Description

The TSB Series Extended Range Refrigerated Bath Circulators - Versatile refrigerated bath circulator with low-GWP natural refrigerants delivering efficient thermal performance and precision temperature control for a wide range of laboratory instruments.

Thermo Scientific™ TSB series Extended Range refrigerated bath circulators combine a stainless-steel bath, refrigeration system, and extended temperature controller for applications that require both deep cooling and high-temperature operation. Available in 8, 12, and 24 L sizes, select models support setpoints from -45°C to +200°C.

Features and benefits

• Reach model-dependent setpoints from -45°C to +200°C.
• Maintain temperature stability up to ±0.06°C.
• Choose an 8, 12, or 24 L reservoir for your sample or application.
• Deliver cooling capacity up to 1 kW at 20°C on select models.
• Adjust pump speed from 30% to 100% or select one of three presets.

Additional product details

Use the bath for temperature-controlled sample work or connect compatible tubing to circulate fluid through an external application. The minimum temperature and cooling capacity depend on the selected bath model. Extended range refrigerated models provide cooling capacities from 450 W to 1 kW at 20°C.

The extended controller supports five step and five ramp programs, each with up to 10 segments. It also provides a connection for an external PT100 probe, sold separately, and RS232 or RS485 communication using Modbus RTU. Audible and visual alarms help monitor temperature and fluid-level conditions.

Fill the reservoir with a heat-transfer fluid approved for the intended temperature range. The selected fluid limits the temperatures available for operation.
