Features and Benefits
The CTD 600 has mayor advantage:
• Extremely small temperature gradients
• No temperature overshoots
• PT100 signal reflects true sample temperature
• No icing at low temperatures
• Compact, robust design
• Automatic adjustment of LN2 consumption as evaporation unit
actively controls continuous flow of liquid nitrogen
• Easy to open, good sample access
• Sample observation during measurement
• Temperature-isolated jacket (hand-warm for safe use)
• Actively cooled jacket according to EN61010-1:2001
• Modular configuration (DMTA torsion/tension, Photo DMTA/UV,
reaction kinetics, SER extensional viscosity, disposable plates, etc.
