EQUIPMENT & ACCESSORIES CATALOG EDITION IV RECIRCULATING HEATERS & CHILLERS
Using the EMS 3500 with Critical Point Dryers
The EMS 3500 will give controlled heating of EMS 3100 Critical Point Dryer. It is connected directly to the inlet and outlet of the EMS 3100 water jacket. The temperature of the circulating fluid is pre-set, typically set to 37°C (eg just above the critical temperature of carbon dioxide).
zzz EMS 3500 Thermocirculator
The EMS 3500 Thermocirculator is a low cost, portable water circulating system for supplying a constant temperature supply for closed and open loop applications at near ambient to +60°C.
Features
z Precise control of heating z Compact z Robust and reliable z No running water to waste
z Ideal for use with the EMS 3100 Critical Point Dryer
Mature Spruce Wood
Critical point dried block of mature spruce wood block, demonstrating transverse, tangential and radial views of tracheids and vessels.
The EMS 3500 is suitable for open and closed loop applications and has all controls and liquid connections on the front panel. The temperature controller shows not only the ‘set’ temperature (between ambient and +65°C), but also the actual liquid temperature. The fluid is circulated by a glandless magnetic pump, through an aluminum reservoir.
A cooling coil is mounted in the liquid reservoir. This coil can be directly connected to the main water supply and is primarily used when temperature control near to ambient is required. The electronic control system features a zero voltage switching unit which minimizes mains electrical interference, enabling the EMS 3500 to be used and sited with other sensitive electronic instruments.
