Description

The TSB Series Standard Range Heating-only Bath Circulators - Versatile heating-only bath circulators delivering efficient thermal performance and precision temperature control for a wide range of laboratory instruments. Suitable for applications requiring internal or external circulation.

Thermo Scientific™ TSB series Standard Range heating-only bath circulators combine a stainless-steel reservoir with an integrated circulator for heating laboratory samples and circulating fluid to external equipment. Available in 8, 12, 24, 36, and 48 L sizes, these models heat to +100°C, with the minimum operating temperature above ambient depending on bath size.

Features and benefits

• Maintain bath temperature with stability up to ±0.06°C.
• Select an 8 to 48 L bath volume to suit the sample or vessel size.
• Program five step and five ramp routines, each with up to 10 segments.
• Circulate heated fluid to an external application using the integrated pump.
• Monitor operation with audible and visual alarms and an adjustable high-temperature cut-off.

Additional product details

Use the bath for temperature-controlled sample work, or connect compatible tubing to circulate heated fluid through an external application. The standard controller supports temperatures up to +100°C. The minimum operating temperature ranges from ambient +5°C to ambient +8°C across bath sizes.

Each bath includes a stainless-steel reservoir and a drain to help remove heat-transfer fluid during routine maintenance. The controller provides a connection for an external PT100 probe, sold separately, and supports RS232 or RS485 communication using Modbus RTU.

These models provide heating without active refrigeration. Choose a suitable heat-transfer fluid for the target temperature and application. For temperatures near or below ambient, use a refrigerated bath or supplemental cooling.
