Acrylic Open Baths. Provide good visibility of immersed samples, never rust,
and cost less than stainless steel baths. The upper working limit of these acrylic

• Low-Cost Operation -
An Economical
Alternative to Dry Ice PolyScience VLT and KR Series Coolers can be used to achieve low-temperature capability with non-refrigerated
or Liquid Nitrogen circulators or boost the cooling capacity of refrigerated circulators.
• Designed For VLT Series Coolers are available with immersion probes only. They are capable of achieving cooling temperatures
Continuous Use as low as -100°C. VLT 100 models feature a digital temperature display and may be ordered with or without
temperature control; non-temperature controlled models operate at maximum cooling. The VLT 60 also operates
at maximum cooling (-60°C). It does not display temperature.
KR Series Coolers are available in both immersion probe and flow-through models. They are capable of achieving
cooling temperatures as low as -45°C. All KR models are designed to run at maximum cooling; temperature
control must be provided by an external circulator. The flow-through model must be used in-line with a circula-
tor pump. Because of its high cooling efficiency, an anti-freeze solution is required in the circulating system.
Immersion Probe style coolers (VLT Series, KR 50, and KR 80) are excellent for trapping and Dewar type
applications and can be used to reduce the expense of using dry ice or liquid nitrogen. PolyScience offers
several different styles of immersion probes; all have an insulated flexible hose that allows convenient
placement of the cooling probe.
