ACCESSORIES

 

 

PolyScience KR and VLT Series Coolers can be used to achieve low-
temperature capability with non-refrigerated circulators or boost the cooling capacity of refrigerated circulators. They're also ideal for replacing dry ice or liquid nitrogen. All models in the KR and VLT Series are designed to run at maximum cooling rate; temperature control must be provided by an external circulator.

Immersion Probe style coolers
are excellent for trapping and dewar type applications and can be used to reduce the expense of using dry ice or liquid nitrogen. A 3-ft. (.9 m) flexible hose allows convenient placement of the cooling probe.

Flow-Through style coolers
must be used in-line with a circulator pump. Because of their high cooling efficiency, an anti-freeze solution is required in the circulating system.
