G GRANT QB Series Dry Block Heating Systems

The dry block heating systems combines digital temperature control for precision, and uniformity.

Applications

A source of precision temperature control for general, routing applications and sensitive analytical procedures including enzyme digestions, enzyme activity studies and nucleid acid hybridisations.

About

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.
