Flow-Through Cooler
This auxiliary device is often used with open baths or
heated Circulators when rapid cool down or operation at
or near ambient temperature is required. A Flow-Though
Cooler can also serve as a source of supplemental
cooling when used in conjunction with a refrigerated
Circulator or to add cooling to heated Circulators.
Because a Flow-Through Cooler provides refrigeration
only, an external pump or other source of circulation
is required.
Flow Rate
The volume of fluid pumped in a given amount of time. It
is measured using water at a pressure of 0 psi (0.0 bar).
Pressure Flow Rate is measured at the outlet port of the
unit; Suction Flow Rate is measured at the inlet port.
General Purpose Water Bath
A vessel that can be held at a desired temperature via
an integral heater and temperature controller. A General
Purpose Water Bath does not incorporate a mechanical
means of fluid circulation.
Heat Exchanger
A device used to transfer heat from one material
or medium to another. Example: 3370 Liquid-to-
Air Recirculator. May also be called a condenser or
evaporator when used within a system.
Heat Load
The amount of heat that is being generated by a device.
Heat load calculations are generally used to determine
the amount of heat removal needed to maintain the
device at a desired temperature.
Heated Circulating Bath
A bath with an integral pump, heater, and temperature
controller. The circulation of fluid inside the bath
reservoir results in better temperature stability and
uniformity. All PolyScience Circulating Baths are capable
of external circulation.
Immersion Circulator
A combination integral pump, heater, and temperature
controller that can be secured to a stand-alone tank
or reservoir to form a complete Circulating Bath. The
PolyScience MX Immersion Circulator can provide
precise temperature control for tanks up to 28 liters.
Immersion Cooler
An auxiliary device used to provide rapid cooling for small
quantities of liquids or as a replacement for dry ice. An
Immersion Cooler can also be used in conjunction with
an open bath or heated Circulator to speed cool down or
provide more precise control when operating at or near
ambient temperature. Cooling is provided via a probe or
cooling coil inserted directly in the liquid.
LidDock
An innovative design that provides for convenient,
no-mess reservoir cover placement when adding liquid
or working with samples. Available on PolyScience
integrated Circulating Baths, the LidDock System allows
condensate to drain back into the reservoir, yet doesn’t
interfere with controller viewing or operation.
Liquid-to-Air Recirculator/Heat Exchanger
A closed-loop, non-refrigerated system designed to cool
an external device by transferring its heat to the air via
an integrated heat exchanger.
Liquid-to-Liquid Recirculator/Heat Exchanger
A closed-loop, non-refrigerated system designed to cool
an external device by transferring its heat to facility
cooling water via an integrated heat exchanger.
Open-Loop Circulation
This is generally used in reference to systems or
applications where liquid is pumped from a Circulating
Bath to an external open tank and then returned to the
circulating bath. A Duplex pump (pressure/suction),
such as that featured on PolyScience Circulating Baths
with Performance and Advanced Series Temperature
Controllers, is required for open-loop circulation
OpenMode Programming
Unique to PolyScience Performance Programmable
Controllers, this feature places no restrictions on the
number of time/temperature programs that can be stored
or the number of steps a program can have. Limit is
dependent on controller memory.
Operating Temperature Range
This is the temperature range that the equipment is
capable of achieving and may be broader than the Working
Temperature Range. This extended temperature range
is particularly useful for the cooling of devices — such as
lasers — that must be brought up to a temperature above
ambient before operation can begin.
