Labo Cube External Sealed System Cooling Water Circulator
CF321P
*

External sealed system cooling water circulator with a built-in solvent collection device that can be installed under a draft chamber or a sink and is compatible with Labo Cube.
CF321P has a solvent collection device that has an external link mechanism to stop the circulation pump through the connection to the Teflon diaphragm vacuum pump and an external device.

Operating Temp. Range
-20 deg.C to room temp.
Cooling capacity
400W (at liquid temp.: 10 deg.C)
PDF Catalog
  • Employs non-Freon refrigerant R404A that conforms to the regulations on specific Freon.
  • Settings and display is made digitally on the operation part, which also has a timer function.
  • CF321P has an external link function that reminds the user to turn off the circulator when operation finishes by linking to an external device. You can also use the vacuum pump stop delay timer function of the rotary evaporator RE601/801 by connecting to it.
  • The circulation water flow adjusting cock, the discharge cock, and an overflow discharge port, an over current electric leakage breakers are located on the front of the unit and thus enable easy operation.
