A versatile general purpose system with two 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.

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.

Specifications

High power heater for fast heat-up – 25ºC to 100ºC in only 15 minutes.
Simple-to-use rotor plus two keys provide access to the interactive interface for fast, accurate set-up and use
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
Overtemperature cut-out protects your samples and your workplace
High quality, robust construction in streamlined coolwall aluminium and chemical-resistant plastic – durable in demanding environments
Compact footprint to optimise use of benchspace
Options include blocks for 0.2 ml tubes, strips and 96-well microtitre plates used in molecular biology and biotechnology applications (QBD2 & QBH2 only)
Three programmable temperature/time segments plus end-of program segments (QBH2 only)
