The PolyScience family of Immersion Circulators makes it easy to create your own unique bath for above ambient temperature control. Simply combine one of our versatile Analog, Standard, or Programmable Controllers with any PolyScience open bath or your own tank or container.
- Standard, analog, or programmable controller
- Up to 30 liter/minute pumping pressure
- Control at temperatures up to 200°C
- Integral temperature and low-liquid level protection
- Time/temperature programmability, RS-232 interface and remote probe capability (Model 7312)
Analog Model 712
This low-cost circulator offers good temperature control for routine lab applications. Proportional heater control combined with redundant safety backup makes this analog model an excellent value. The 2-speed pressure (simplex) pump minimizes turbulence in small tanks and can provide higher flow and greater uniformity in large tanks. Temperature readout is via the supplied thermometer (alcohol).
Standard Model 7306
The PID microprocessor controller provides precise temperature control and greater temperature stability. The 2-speed pressure (simplex) pump minimizes turbulence in small tanks and provides higher flow and greater uniformity in large tanks. An adjustable flow director accepts ½” (13mm) ID tubing for external circulation.
Progammable Model 7312
The full-featured PolyScience Programmable Controller, combined with circulator placement flexibility, makes this "design your own bath" circulator a great value. Microprocessor PID control assures high accuracy and stability.
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” 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.
