open bath or your own tank or container.
Standard Digital 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 provide higher flow and greater uniformity in large tanks. An adjustable flow director accepts 1/2 in. (13mm) ID tubing for external circulation.

Basic 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).
