TSB Series Standard and Extended Range Immersion Circulators

Thermo Scientific™ TSB series Standard and Extended Range Immersion Circulators add controlled heating and fluid circulation to a compatible open bath or vessel. Choose a standard controller for temperatures up to +100°C or an extended controller for temperatures up to +200°C. The integrated pump can also circulate temperature-controlled fluid through an external application. Cooling below ambient requires a compatible refrigerated bath.

Features and benefits

• Maintain fluid temperature with stability up to ±0.06°C.
• Select a standard or extended controller to match the required maximum temperature.
• Program five step and five ramp routines, each with up to 10 segments.
• Circulate fluid within the bath or through an external application.
• Monitor operation on the digital display and respond to audible and visual alarms.

Additional product details

These configurations provide the immersion circulator head for use with a compatible bath or vessel. Immersion-circulator-only models include a bridge plate assembly for mounting the head. Check bath size and compatibility before connecting the unit.

The standard controller supports one pump speed and temperatures up to +100°C. The extended controller supports three preset pump speeds or adjustment from 30% to 100%, with temperatures up to +200°C. Maximum flow rates are 15 L/min for the standard controller and 25 L/min for the extended controller.

Select the unit's internal sensor or connect an external PT100 probe for temperature control at the application. The external probe is sold separately. RS232 and RS485 serial interfaces with Modbus RTU support remote monitoring and control. A refrigerated bath is required for cooling.
