Main TabsDescriptionA 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. QBD / QBH series The Grant QBD / QBH series are a versatile range of high quality digital dry block heating systems with excellent temperature control and a wide choice of interchangeable blocks for maximum flexibility. The outstanding performance of the QBD / QBH series is based on advanced digital temperature control combined with high quality, precision-engineered blocks providing excellent thermal contact. The result is accurate, reproducible and safe heating of your samples. There is a full range of models and options to cater for basic through to more sophisticated applications - choose from three digital systems with 1, 2 or 4 interchangeable blocks (QBD models) and one digital high-temperature system (QBH2) with 2 blocks. These are complemented by an extensive range of interchangeable heating blocks to accommodate your sample tubes - from our standard range of blocks or tailored to suit your application. In addition, for 2-block systems QBD2 and QBH2 we offer accessory blocks for accommodating microplates and microtube strips. Heating range ambient + 5°C to 130°C (all three QBD models) or ambient + 5°C to 200°C (QBH2) Rapid heat-up time Stability and uniformity ± 0.1°C Integral timer function optional external probe for in-sample or in-block temperature control Robust, compact, contemporary design Block extraction tool included as standard, for easy and safe removal of blocks SpecificationHigh 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) • = standard QBD1 QBD2 QBD4 QBH2 Dimensions (h x d x w) 120 x 240 x 200mm 120 x 285 x 200mm 120 x 390 x 200mm 120 x 295 x 200mm Temperature range @37°C Ambient +5 to 130°C Ambient +5 to 130°C Ambient +5 to 130°C Ambient +5 to 200°C Stability @37°C 0.1±ºC 0.1±ºC 0.1±ºC 0.1±ºC Uniformity within the block @37°C 0.1±ºC 0.1±ºC 0.1±ºC 0.1±ºC Uniformity across similar blocks @37°C 0.2±ºC 0.2±ºC 0.2±ºC 0.2±ºC Temperature display • • • • Display resolution 0.1°C 0.1°C 0.1°C 0.1°C Heat up time 25ºC to 100ºC 20 minutes 20 minutes 20 minutes 15 minutes Three programmable temperature/ time segments plus end-of-program segments - - - • Reaction timer, with audible buzzer 1 to 999 minutes 1 to 999 minutes 1 to 999 minutes 1 to 999 minutes Function timer for delay of heater start-up/switch-off Up to 72 hours Up to 72 hours Up to 72 hours Up to 72 hours Off-set adjustment • • • • Two-point calibration of internal and external probes • • • • High/low temperature alarms, settable to within 0.5ºC of set temperature • • • • Fault indication display • • • • Extraction tool for easy and safe block removal • • • • Safety Thermal fuse Thermal fuse Thermal fuse Thermal fuse Heater power - 230V 150W 300W 600W 300W Heater power - 120V 100W 200W 400W 200W Supply voltage 120 or 230V 120 or 230V 120 or 230V 120 or 230V Weight 2.2kg 2.7kg 3.6kg 3kg DownloadsProduct Manuals: QBA QBD QBH Block Heater Operating Manual - Multi-Language Product Manuals QBA QBD QBH Block Heater Operating Manual - Multi-Language Further Information: 7.2 Q8D2 Dry Block Heaters Further Information 7.2 Q8D2 Dry Block Heaters Video Grant Instruments digital dry block heater with interchangable blocks HD Video of Grant Instruments digital dry block heater with interchangable blocks HD ApplicationsA source of precision temperature control for general, routing applications and sensitive analytical procedures including enzyme digestions, enzyme activity studies and nucleid acid hybridisations. * Offer valid on new orders only.
