These products eliminate the need for numerous, cumbersome sample vessels, connectors, and manual sample transfer steps during concentration, fractionation, solvent, and buffer exchange operations. 2.0 Ultralab System Description 2.1 Ultrareservoir™ Container Description The Ultrareservoir containers are constructed of clear acrylic and have connections in the base plate for simple and convenient hookup to the TFF filtration device and pump. The polypropylene valves and barb connectors can isolate the reservoir from either the pump or the device. This allows for quick changes of pump tubing or replacement of filtration device. A pressure gauge monitors feed pressure, thereby maintaining control during operation. The airtight lid creates a siphon for unattended buffer exchange during constant volume diafiltration. 2.2 Ultrapump™ II Description Ultrapump II laboratory peristaltic pumps provide controlled recirculating flow across the membrane surface. The pump features a quick-access pump head that permits fast and easy tubing replacement. Its self-priming, positivedisplacement operation minimizes sample foaming. A variable speed controller regulates how much fluid can be pumped by the unit allowing for precise adjustment of operating conditions during sample processing. An Ultrapump II pump is also useful for typical liquid transfer operations. 3.0 Ultralab System Components 1 – Ultrareservoir Container 1 - Package with Ultrareservoir components (refer to Ultrareservoir Container Plumbing Assembly diagram on page 3) 1 - Ultrapump II peristaltic pump 1 - Quick Load* pump head 1 – Ultrasette™ Accessory Kit (Ultralab Systems with 500 mL Ultrareservoir Containers, include the Mini-Ultrasette™ Accessory Kit) NOTE: Use Teflon* tape or PTFE tape on all fittings with threaded parts to ensure proper seal and prevent leakage. 4 4.0 Ultrapump™ II Setup 4.1 Tubing Addition/Replacement Pump Head Body Latch Pump Head Body Tubing Retainer Rotor Assembly Latch Latch Rotor Assembly Tubing Retainer Fluted Knob Figure 1 Fluted Knob Figure 2 4.1.1 Attach pump head onto the pump by following the directions that are supplied inside the box with the pump head. 4.1.2 Unscrew the fluted knob on upper part of the pump head and lift out tubing retainer. Pull down on the latch on the underside of the pump head until it snaps open (Figure 1). Swing open the two halves of the pump head as far as they will go. 4.1.3 Cut approximately 2 ft (0.6 m) of PharMed* thick wall tubing, or appropriate length of tubing to fit connection desired, and loop the tubing around the roller on rotor assembly (Figure 2). CAUTION: Carefully center tubing on roller of rotor assembly. If not centered and tubing touches front edge of rotor assembly, wear will be more severe. 4.1.4 While gently pulling up on the tubing, swing down the two halves of the pump head and snap the latch into place (Figure 2). NOTE: To minimize hold-up volume, use the shortest length of tubing possible for operation. 4.1.5 Replace the tubing retainer with the "V" slots facing the tubing and screw on the fluted knob. Tighten only until the tubing is held firmly in place — overtightening will restrict flow. CAUTION: Pall Life Sciences recommends PharMed* or Marprene II* Highperformance tubing for 10-40 psig applications and extended tubing life. Silicone-type pump tubing should not be used for extended operation or at pressures greater than 10 psig because tubing may break. 5 5.0 Ultrareservoir™ Container Setup 5.1 Equipment Required 5.1.1 Vessel to collect filtrate 5.1.2 Vessel to collect final concentrate 5.1.3 Vessel containing diafiltrate solution (if performed) 5.1.4 Vessel containing cleaning solution (see page 11) 5.2 Suggested Connection of Ultrareservoir Container and Tangential Flow Filtration Device From Device Back Pressure Valve 3-Way Valve To Pump From Pump To Device Filtrate Collection Vessel Figure 3 5.2.1 Connect the 3-way/Back Pressure Valve assembly to the “From Device” port on the reservoir. Screw in assembly just enough to ensure a tight fit. (Refer to Ultrareservoir™ Container Plumbing Assembly Diagram on page 3.) CAUTION: Do not apply excessive force to valve assembly after insertion into reservoir, as fracture may occur. It is recommended that the valve assembly always be supported with one hand when opening or closing the 3-way valve. 5.2.2 Place reservoir on top of pump as shown in Figure 3, or on the benchtop next to pump as shown in Figure 4. 5.2.3 When facing the pump, take the tubing that extends from the left side of the pump head and connect it to the “To Pump” barb connector. Secure the tubing on the barb connector with a tubing clamp. 6 From Device 3-way Valve/Back Pressure Assembly Gauge Assembly To Pump From Pump To Device Filtrate from TFF Device Figure 4 5.2.4 Take tubing that extends from the right side of the pump head and connect to the “From Pump” barb connector. Secure the tubing on the barb connector with a tubing clamp. 5.2.5 Insert the polypropylene tee with gauge assembly to the “To Device” port on the reservoir. Screw in assembly just enough to ensure a tight fit. (Refer to Ultrareservoir™ Container Plumbing Assembly diagram on page 3.) 5.2.6 Cut two pieces of PharMed* tubing the appropriate length, attach the Gauge Assembly and the 3-way/Back Pressure Valve Assembly to the TFF device. Secure the tubing on each hose barb connector with tubing clamps. NOTE: To minimize hold-up volume, use the shortest length of tubing possible for operation. 5.2.7 Connect the tubing extending from the Gauge Assembly to the FEED port of the TFF device (Ultrasette shown in Figure 3 and 4) and the tubing extending from the 3-way/Back Pressure Valve Assembly to the Retentate port of the filtration device. Secure with tubing clamps. 5.2.8 Check that both anti-vortexing plugs are seated properly in the bottom of the reservoir. The open ends of each plug should be parallel to the walls of the reservoir so that flow is diverted equally in both directions. This will ensure proper sample exit and return with minimal shear and foaming. 5.2.9 Connect tubing (3/16" I.D.) to the barb fitting on the 3-way valve (which can be used to collect final concentrate or to direct flush volumes to drain). The length should be adequate to reach either a drain or another collection vessel. See Figure 5 on next page. 7 Beaker for final concentrate or drainage of flush volume 3-Way Valve (positioned for retentate collection and closed for recirculation) Back Pressure Valve (closed position shown will not allow for recirculation) Figure 5 6.0 Operation of Ultralab™ System 6.1 Preparation for Start Up 6.1.1 Plug the line cord of the pump into any grounded, three-wire AC receptacle making sure speed dial is at zero and the forward/reverse switch is in the "Off" position. "Forward" position is with the switch pushed to the right; "Reverse" position is with the switch pushed to the left; "Off" is between these two positions. 6.1.2 Turn the 3-way Valve and Back Pressure Valve on the reservoir to allow fluid to recirculate into the reservoir. The recirculation position of these valves is when the valve stem is parallel to the valve body. Be aware of the correct position of these valves for retentate recirculation. 6.1.3 Now, position the 3-way Valve as shown in figure 5, so fluid will not drain from the Ultrareservoir Container when the rinsing or preconditioning solution is added. (Figure 5 shows the 3-way Valve in the retentate collection mode, and the Back Pressure Valve in the closed position.) 6.2 Rinsing and Preconditioning Follow the rinsing steps below before filtering sample through a new membrane filtration device or one that has been stored in a storage agent (0.1 N NaOH). If your sample contains buffer, preconditioning of the membrane filtration device must be performed (see step 11 of this section). 6.2.1 Using Table 1 below as a reference, fill reservoir with appropriate volume of deionized (DI) water. Volume of Deionized Water/Buffer Required 500 mL 2 Liter 5 Liter Ultrareservoir™ Ultrareservoir Ultrareservoir Container Container Container Ultrasette™ 200 mL 500 mL 1000 mL Lab Tangential Flow Device Table 1 6.2.2 Flip the forward/reverse switch into the "Forward" position and slowly turn the speed dial clockwise until the setting corresponds to the required recirculation rate. See Table 2 on next page. 8 6.2.3 Filter Unit Channel Type Pump Recirculation Rates* Pump Tubing *Recirculation Rate Ultrasette™ Screen Ultrapump™ 1/4" I.D. (#24) 1.0-2.0 Liter/min Ultrasette Ultrapump 1/4" I.D. (#24) 1.5-2.5 Liter/min Suspended Screen * Recirculation rates apply to PharMed® tubing only Table 2 6.2.3 Slowly turn the Back Pressure Valve toward the closed position until the pressure gauge reads 20-35 psi. This will generate filtrate flow rate. 6.2.4 Direct filtrate to drain until 50% of added volume passes through filtrate. 6.2.5 Turn speed dial setting to "0". 6.2.6 Open the Back Pressure Valve and position the 3-way Valve to recirculation mode. 6.2.7 Turn the pump on and adjust to a very low recirculation rate. 6.2.8 Discard the Dl water that will exit the Sample Port. 6.2.9 Turn the speed dial setting back to "0", position the 3-way Valve in the recirculation mode, and the Dl water remaining will flow into the reservoir. 6.2.10 Repeat steps (6.2.5 – 6.2.8) above for maximum Dl water removal. 6.2.11 If buffered samples are to be processed, repeat steps 6.2.1 – 6.2.10 above using buffer. This will precondition the Ultralab™ system to the proper pH and ionic conditions prior to sample filtration. 6.3 Sample Filtration 6.3.1 Add sample to be processed to the Ultrareservoir Container. If diafiltration is to be performed, press lid firmly into place and refer to the Diafiltration Procedure (section 6.5). 6.3.2 Position the 3-way Valve in the recirculation mode and open the Back Pressure Valve. 6.3.3 Flip the forward/reverse switch into the "Forward" position and slowly turn the speed dial clockwise to get the required recirculation rate. (See Table 2) 6.3.4 Slowly turn the Back Pressure Valve toward the closed position until the pressure gauge reads 20-35 psi. This will generate filtrate flow rate. 6.3.5 The sample in the reservoir will continue to decrease in volume equal to the volume of filtrate generated. Continue operation until the desired concentration factor is achieved. For example, 2,000 mL concentrated to 200 mL is a 10X or ten-fold concentration. 6.3.6 Monitor pressure while maintaining a constant recirculation rate (speed dial setting). The pressure may increase during concentration due to viscosity. Adjust pressure if it is above or below 20-35 psi. 6.3.7 Sample has reached maximum volume reduction (final concentrate) when air begins to be drawn into the pump. Stop filtration at this point. 9 6.4 Concentrate Recovery 6.4.1 When final concentration is attained, turn the pump speed dial setting to "0" to stop recirculation. 6.4.2 Fully open the Back Pressure Valve and then position the 3-way Valve to direct the retentate into a collection vessel. 6.4.3 Turn the pump on and adjust to a very low recirculation rate. 6.4.4 Collect the concentrated retentate that will exit the Sample Port. 6.4.5 Turn the speed dial setting back to "0", position the 3-way Valve to recirculation mode, and begin recirculation at a very low recirculation rate. The concentrate remaining in the filtration device will flow into the reservoir. 6.4.6 Repeat steps (6.4.1 – 6.4.5) above for maximum concentrate recovery. 6.5 Diafiltration Procedure For salt removal, buffer exchange, or macromolecular fractionation, use diafiltration. See the Diafiltration and Buffer Exchange article referenced on the Pall Corporation website for more information on this technique. Figure 6 6.5.1 Gently press the lid onto the reservoir until it is firmly seated. 6.5.2 Cut a 12-20 inch piece of 3/16 inch I.D. tubing and connect to barb connector located on top of lid. Secure tubing with clamp if necessary. 10 6.5.3 To initiate diafiltration during sample filtration, place end of tubing into vessel containing either buffer for buffer exchange or water for salt removal. Once a vacuum is created in the closed system, the solution will begin moving up the tubing and into the reservoir. The rate the fluid is drawn into the Ultrareservoir Container is the same as the rate the filtrate is collected from the Ultrasette TFF Device. NOTE: For best operation, the tubing end should rest at the bottom of the vessel. If siphoning does not occur, gently press down on the lid to insure that system is properly sealed. 6.5.4 The diafiltration technique can be interrupted or stopped by simply removing the tubing from the diafiltraion fluid. 6.5.5 The sample will begin to concentrate once all the diafiltration volume has been drawn into the reservoir. 7.0 Ultrareservoir Shutdown 7.1 Rinsing Procedure To maximize recovery of sample concentrate, a rinsing cycle can be utilized. 7.1.1 Referencing Table 3 below, add appropriate volume of water or buffer to reservoir. NOTE: If sample contains buffer, then utilize buffer in the rinsing step to prevent possible sample loss due to precipitation or denaturization. Volume of Deionized Water/Buffer Required Ultralab™ System Ultralab System Ultralab System 2L 5L 500 mL Ultrasette™ 40 mL 50 mL 70 mL Lab Tangential Flow Device Table 3 7.1.2 Fully open the Back Pressure Valve and position the 3-way Valve for retentate collection (closed for recirculation mode). 7.1.3 Turn the pump on and adjust to a very low recirculation rate (speed dial setting 1-3). 7.1.4 Collect the concentrate that will exit the Sample Port. 7.1.5 Turn the speed dial setting back to "0", position the 3-Way Valve in recirculation mode, and return speed dial setting to 1-3. The concentrate remaining in the filtration device will flow into the reservoir. 7.1.6 Repeat steps (7.1.2 – 7.1.5) above for maximum concentrate recovery. 11 7.2 Cleaning Procedure 7.2.1 Follow steps 6.2.1 – 6.2.10 in the Rinsing and Preconditioning procedure (section 6.2) using one of the following cleaning agents in place of DI (deionized) water or buffer: Cleaning Agents Cleaning Agent Alconox® Powdered Precision Cleaner Sodium Hydroxide Tergazyme™ Enzyme-Active Powdered Detergent Sodium hypochlorite Concentration 1% 0.1N @ 25°C 1% 0.005% Table 4 7.2.2 Repeat steps 6.2.1 – 6.2.10 in the Rinsing and Preconditioning procedure using DI water to remove residual cleaning agents. 7.2.3 The anti-vortexing plugs may be removed for manual cleaning. 7.2.4 Follow manufacturer’s instructions for cleaning the filtration device. 7.3 Storage After cleaning, the Ultrareservoir™ Container can be stored dry. If the filter unit is attached, the system should be stored wet. If stored wet, use 0.1 N Sodium Hydroxide (NaOH) solution as the storage agent. Follow manufacturer’s instructions for filtration device storage. 7.4 Pump and Pump Tubing Care 7.4.1 Replace the pump tubing after cleaning or prior to initial operation. 7.4.2 Periodically, wipe off the pump and pump head with soap and water. NOTE: Check pump tubing frequently for wear. 12 8.0 Ultrareservoir™ Container Chemical Compatibility √ = Compatible NR = Not Recommended Reagent Acetic Acid (5%) Acetic Acid (25.5%) Acetone (≤ 30%) Acetonitrile (≤ 40%) Alconox(1%) Aliphatic and Aromatic Esters Amines Ammonium Chloride (1%) Ammonium Hydroxide (5%) Aromatic and Chlorinated Hydrocarbons Butanol (70%) Butyl Acetate (40%) Butyl Cellosolve (10%) Calcium Chloride (5%) Chloroform (0.8%) Citric Acid (1%) Dimethylacetamide (DMAC) (≤ 40%) Dimethylformamide (≤ 40%) Dimethyl Sulfoxide (≤ 40%) Disodium Salt of EDTA (10%) Ethanol (70%) Ethers Ethyl Acetate (≤ 30%) Formaldehyde (1%) Formic Acid (5%) Glutaraldehyde (0.5%) Glycerin (50%) Guanidine HCI (6M) Hydrochloric Acid (0.1N @ 25° C) Hydrochloric Acid (0.1N @ 50° C) Hydrochloric Acid (1.0N @ 25° C) Hydrogen Peroxide (1%) Isopropyl Acetate (1%) Isopropyl Alcohol (25%) Ketone Lactic Acid (5%) Mercaptoethanol (0.1%) Methyl Alcohol (25%) Methylene Chloride (1%) Methyl Ethyl Ketone(1%) N-Methyl Pyrrolidone (1%) Nitric Acid (£1%) Oxalic Acid (1%) Phenol (0.5%) Phosphate Buffer (pH: 8.2) (1M) Phosphoric Acid (1N) Sodium Azide(1%) Sodium Chloride (5%) (50° C) Sodium Deoxycholate (5%) Sodium Dodecyl Sulfate (0.01M) Sodium Hydroxide (0.1 N @ 25° C) Sodium Hydroxide (0.1 N @ 50° C) Sodium Hydroxide (0.5N @ 25° C) Sodium Hydroxide (1.0N @ 25° C) Sodium Hypochlorite (0.005%) Sodium Hypochlorite (0.02%) Sodium Nitrate Sulfuric Acid(1%) TergaZyme™ (1%) Tetrahydrofuran (5%) Toluene (1%) Tris® buffer (pH: 8.2)(1M) Triton® X-100 (0.002M) Urea (25%) Ultrasil® 11 (1%) Table 5 13 √ NR NR NR √ NR NR √ √ NR NR NR NR √ NR √ NR NR NR √ √ NR NR √ √ √ √ √ √ NR NR √ √ √ NR √ √ √ √ √ √ √ √ √ √ √ √ √ NR √ √ NR √ NR √ NR √ √ √ NR √ √ √ √ √ 9.0 Ultralab™ System Specifications 9.1 Ultrareservoir™ Container Specifications Total Volume Ultrareservoir Container 500 mL 500 mL Ultrareservoir Container 2 mL 2,000 mL Ultrareservoir Container 5L 5,000 mL 15-20 mL 20-30 mL 20-30 mL < 2 mL 4.0 mm (5/32 in.) < 2mL 6.4 mm (1/4 in.) < 5 mL 6.4 mm (1/4 in.)
