Navigating the challenges of precise temperature control requires tools that are both capable and adaptable. Lab1st's three circulator series—DC, HR, and HRV—offer a spectrum of solutions designed to meet your critical requirements without compromise. From benchtop efficiency to expansive thermal performance, explore our range to discover the perfect balance of size, capability, and value for your application.

DC Series Heating Cooling Circulator
The DC series is a compact, open-bath circulator ideal for space-conscious lab environments. With an operating range of -5 °C to 95 °C, it supports both internal and external circulation, enabling precise temperature control inside the bath or with external apparatus. Its intelligent control system ensures rapid heating and stable temperature maintenance. Additionally, the compressor can initiate cooling even at high temperatures, enhancing operational flexibility.

• Desktop design with a small footprint
• Suitable for internal and external circulation
• High temperature stability and control accuracy
• Compressor-assisted fast cooling at elevated temperatures

HRV Series Hermetic Heating Cooling Circulator
Engineered for demanding applications in pharmaceutical, chemical, and biological sectors, the HRV series operates across an extensive temperature range of -100 °C to 200 °C. It incorporates a fully sealed fluid path paired with a high-efficiency plate heat exchanger, minimizing thermal fluid volume while improving heat transfer efficiency for faster heating and cooling rates. The system features an expansion vessel maintained at 60 °C, ensuring that the heat transfer fluid remains stable, reducing moisture absorption and evaporation risks throughout operation.

• Broad operating range with both heating and cooling capabilities
• Comprehensive safety protection: PT100 sensor, overvoltage, delay, overcurrent, overheating, and leakage protection
• Customizable high-power configurations available
• Upgradeable to PLC-based remote control
