Grant QBD4 Digital Dry Block Heater four block
Description:
For controlled, dry heating of test tubes, microplates and Eppendorf tubes in aluminium blocks.
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.
High power heater for fast heat-up: 25ºC to 100ºC in only 15 minutes
Clear digital display - easy to read from a distance for instant reassurance
Convenient timer facility, with audible buzzer, for reaction timing and function timing, e.g. delayed heater switch-on/turn-off
Wide range of interchangeable blocks enables you to mix and match sample tubes as desired - extraction tool supplied as standard for easy and safe removal of blocks.
Optional safety cover - protects samples from contamination and users from accidental contact with hot blocks
