Grant QBA1 Heat Block

• Enzyme digestions and activity studies requiring consistent and controlled heating.
• Nucleic acid hybridizations and other temperature-sensitive molecular biology processes.
• Incubation of samples in tubes or microplates for various biochemical assays.
• Sample preparation for analytical techniques where precise temperature control is critical.

Typical capacity

Designed to accommodate various tube and microplate formats via interchangeable blocks; specific capacity depends on the block installed.

Power supply

Typically operates on a standard laboratory power supply, commonly 230V, 50/60Hz for units of this type in the UK.

Temperature range

For this class of equipment, typically ambient +5°C up to 100-130°C, depending on the associated dry block heater.

Temperature uniformity

Often specified as ±0.1°C to ±0.2°C across the block, critical for sensitive applications.

Block material

Commonly constructed from anodised aluminium for efficient heat transfer and durability.

Compatibility

Specifically designed for use with Grant Instruments QB Series Dry Block Heating Systems.
