Hoses All circulators and cryostats are always delivered with nozzles manufacturer for tubings with an inner Ø of 8 and 12 mm. The tubings and insulation (if applicable) have to be ordered separately and should be selected according to the application. The carefully selected and proven heat transfer liquids offer the following advantages: • Eliminates health hazards and minimizes unpleasant odors. • High resistance against aging while retaining a lowviscosity with a low corrosive tendency. Description Order-No. 333-0292 Insulated metal tubing made from stainless steel 100 cm long with M 16 x 1 unions on both ends. To be used from -50 to +300°C. 50 cm long 333-0293 Note: Good ventilation is recommended when working at temperatures > 200°C. 150 cm long 333-0294 coupling to connect 2 tubings to each other 001-2560
Tubings / Bath Liquids coupling for circulation set C-/DC-line 333-0302Insulated metal tubing made from stainless steel with M 16 x 1 unions on both ends. Especially for the low temperature range -90..105°C100 cm long 1. Viscosity For optimum temperature accuracy it is very important that the heat transfer liquid be of low viscosity. 333-0578 150 cm long 333-0579 coupling to connect 2 tubings to each other 001-2560 coupling for circulation set C-/DC-line 333-0302PVC tubing 2.

Ø ; per meter 082-0173Foam rubber insulation This is the range within which the circulator can be operated optimally over a longer period of time. The maximum viscosity is approx. 5 mPas. Operating temperature range: The circulator may be operated only within this range over a longer period of time under certain conditions. Viscosity may rise to a maximum of 30 mPas. The pump capacity no longer matches the specifications made in the brochure. Heating range: for PVC, Viton, silicone and Perbunan tubingsfor tubings with 8 mm i. Long-term temperature control in this range is notpermissible as the pump motor’s excess temperatureprotection may switch off the pump. Ø ; per meter 806-0373 for tubings with 12 mm i.
