Heater block for single NW type Valve, without heater cartridge

There are two single valve heater block designs: standard and low mass. The low mass heater block, which has a .075" diameter hole for sensor or thermocouple, works well for two position valves. The standard heater block is a high mass, multipurpose design which can be used with any Valco valve. Sample loops or short columns can be wound directly on it.

Heater blocks do not include a heater cartridge.
