QB Series Dry Block Heating Systems

Designed for flexibility and efficiency the block heaters come with a choice of standard and custom blocks. The versatile dry block heater series are ideal for general sample heating, research or chemistry applications.

A versatile general purpose system with removable/interchangeable blocks and a comprehensive specification to suit most dry block heating applications in the laboratory.

Temperature range ambient +5ºC to 130ºC, with rapid heat-up time
Stability: ±0.1ºC
Uniformity: ±0.1ºC
Digital temperature control for optimal precision
Range of convenient features including alarms, single and dual point calibration, programmed start/stop, 'offset' for known sample temperature variation and choice of external or internal probes
External probe available for accurate in-sample or in-block temperature control
Includes block removal tool for easy and safe removal of blocks.
