  This Refigerating/Heating circulator combines -25°C cooling capacity with a spacious 28-liter reservoir to provide precise temperature control for large or multiple samples even under rapidly changing heat loads. Plus they feature large 10¼ by 10¼ in. reservoir openings to make immersion and retrieval of samples quick and easy.

This model features the "Cool Command" refrigeration system and fuzzy logic energy management technique to deliver up to 50% greater energy efficiency than traditional systems. This advanced technology carefully monitors heat load to deliver only the amount of refrigerant needed. As a result, it permits fast bath cooling even at high temperatures without excessive energy consumption.

A fine choice for more modest applications and budgets, the 9602 features -25° to +150°C temperature control, a powerful 5-speed pressure/suction (duplex) pump for open or closed loop applications, and integral RS232 interface. A full graphic LCD display with multi-language help menus simplify operation and set-up.
