Microbiology Terms Electronic Balance Definition balance that generates a current proportional to the displacement of the pan. Advantage compact, easier and they can be often transported without problems Function used in the accurate measurement of weight of materials Auto-Clave Definition a strong heated container used for chemical reactions and other processes using high pressures and temperatures Advantage Economical or cheap. Short procedure time. Function uses steam under pressure to kill harmful bacteria, viruses, fungi, and spores on items that are placed inside a pressure vessel Hot Air Oven Definition A hot air oven is a laboratory instrument that uses dry heat to sterilize laboratory equipment and other materials Advantage It can work at a higher temperature than autoclave and is faster Function uses dry heat to sterilize laboratory equipment and other materials Laminar flow Definition Laminar Hood is a closed device primarily for processes or instruments sensitive to microbial contamination. Advantage A Laminar Hood is made up of stainless steel, avoiding joints and corners to Function prevent the accumulation of bacterial spores. Direct unrestricted airflow towards sterility and prevent contamination Cooling Incubator Definition An incubator, in microbiology, is an insulated and enclosed device that provides an optimal condition of temperature, humidity, and other environmental conditions required for the growth of organisms. Advantage provides accurate and dependable temperature control Function used to grow and maintain microbiological cultures or cell cultures Wire Loop Definition A tool usually made of platinum or nichrome wire in which the tip forms a small loop with a diameter of about 5 mm. Advantage ensure accuracy by assisting lab researchers to completely transfer the liquid through consistent wetting Function used to smear, streak, or take an inoculum from, a culture of microorganisms Holder Definition is a laboratory utensil shaped like a spoon and is generally made up of carbon steel, stainless steel, porcelain, etc Advantage consists of an insulator handle that allows the user to have a firm grip and avoid injuries. Function used for mixing substances into a solution, stirring the solution, and scrapping objects. Filter Paper Definition A semi-permeable paper barrier placed perpendicular to a liquid or air flow. Advantage Paperless filter assembly can filter particles down to 100 microns Function used to separate fine solid particles from liquids or gases Bottle Definition chemically-resistant containers. Advantage strong enough to withstand significant pressure Function used for holding and dispensing fluids. Beakers Definition cylindrical glass or plastic vessel Advantage beakers can hold samples of whatever you're studying. Function used for holding and measuring liquids Agar Plate Definition thin layer of nutrient gel in a Petri dish Advantage They allow bacteria and fungi to grow on a semi-solid surface to produce discrete Function colonies used to grow bacteria and fungi in the microbiology laboratory Nutrient Agar ML Water 1000 ml Gram Powder 32g Patients max 2000 Citrate Agar ML Water 1000 ml Gram Powder 27.2 g Patients max 15 Plan Agar ML Water 1000 ml Gram Powder 40 g Patients Max 20
