PolyScience Laboratory Baths, Circulators & Chillers

For technical assistance in choosing the right product for your application please contact ThermX at 800-284-3769.

In addition to offering excellent performance and reliability, PolyScience Analog Water Baths come equipped with a tilting, see-through polycarbonate cover and -20° to 150°C alcohol thermometer. The steeply gabled cover is particularly ‘lab friendly’, accommodating glassware of varying heights and permitting easy loading and removal of samples while allowing condensate to drain neatly back into the bath.

Dual thermostats provide optimum protection for your work and water bath. A secondary Safety Set thermostat guards against thermal runaway, automatically disconnecting heater power should bath temperature get too high or the liquid level drop too low.

Digital Microprocessor Controlled Water Baths

• Range: 30 to 100°C
  86 to 212°F
  
• ±0.2°C Uniformity
  
• Accurate microprocessor control
  
• Three user-defined temperature preset buttons
  
• Redundant safety backup
  
• Front panel lockout
  
• Electronic calibration

The latest generation of Digital PolyScience Water Baths offer superior temperature control, range, and uniformity. Bath fluids can be controlled at temperatures as high as 100ºC (60ºC without cover) with 0.1ºC precision and ±0.2ºC uniformity. Bath temperature is displayed continuously on a bright, easy-to-read LED panel in your choice of ºC or ºF. Set point temperature is recalled with just the touch of a button. Three user-defined temperature preset buttons allow for quick selection of often used temperature set points.

Dual thermostats provide optimum protection for your work and water bath. The high limit alarm alerts you if bath temperature exceeds your pre-set limit. A secondary Safety Set thermostat guards against thermal runaway, automatically disconnecting heater power should bath temperature get too high or the liquid level drop too low.

PolyScience Water Baths are also designed for operating convenience. The steeply gabled, polycarbonate cover accommodates glassware of varying heights and tilts out of your way when loading or removing samples, allowing condensate to drain neatly back into the bath.

The Programmable Controller features a multi-language graphic display and time/temperature programming. Ten programs can be stored in the controller's memory; each can have up to fifty steps and can be cycled up to 999 times. An RS232 interface and remote probe capability are standard. The included software supports LabView™ drivers and Excel® macros to offer even greater programming and data logging convenience.

For internal circulation or external open and closed loop applications, the 7312 has a strong pressure and suction (duplex) pump with five selectable speeds. The optional remote probe gives more accurate temperature control in applications where external circulation is required.

The expandable mounting bridge spans openings from 15 to 25 in. across to allow placement on almost any bath container. Choose from PolyScience's selection of stainless steel or acrylic baths or use your own reservoir.
