The E3500 is a water thermocirculator with a heating range of ambient to +65°C) and is suitable for open and closed loop applications. The E3500 is an option for the Quorum E3100 Critical Point Dryer. For heating and cooling applications the E4860 Recirculating Heater/Chiller is recommended.
• Precise control of heating
• Compact design, small footprint
• Robust and reliable
• No running water to waste
• Ideal for use with E3100 critical point dryer
The E3500 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 aluminium reservoir.
A cooling coil is mounted in the liquid reservoir that 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 minimises mains electrical interference, enabling the E3500 to be used and sited with sensitive electronic instruments.
Using the E3500 with the E3100 critical point dryer
The E3500 will give controlled heating of Quorum E3100 critical point dryer. It is connected directly to the inlet and outlet of the E3100 water jacket and the temperature of the circulating fluid is preset, typically to 37°C (e.g. to just above the critical point temperature of carbon dioxide).
The E4800 series are of the ‘closed loop’ type and therefore efficiencies are dramatically improved compared with open bath models. The E4800 series are simple to set up and to operate and essentially maintenance free.
Choosing the correct heater/chiller
In order to optimise performance from a heater/chiller system, the correct specification must be selected for a particular application. To cool or heat any instrument or system it is important to obtain the following information from the manufacturer:
