The Grant QBD4 is a versatile, general purpose dry block heating system with four removable/interchangeable blocks and a comprehensive specification to suit most dry block heating applications.
- Digital temperature control for optimum precision
- Heating range ambient + 5º to 130ºC, with rapid heat-up time
- Stability and uniformity ± 0.1ºC
- 4-block system (models with 1 block and 2 blocks also available)
- Range of convenient programming features
- High power heater for fast heat-up – 25º to 100ºC in only 15 minutes.
- Simple-to-use rotor plus two keys provide access to the interactive interface for fast, accurate set-up
- 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
