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)
