What types of tubes can this heat block accommodate?

This specific listing includes a block designed for 24 x 1.5 mL tubes. Other blocks are available for different tube sizes, but these would need to be sourced separately or confirmed with the seller.

Is this unit suitable for high-temperature applications?

Dry block heaters like the QBT1 are generally suitable for temperatures up to around 100°C, making them appropriate for many common laboratory heating tasks.

Does this unit require any consumables?

Beyond the sample tubes themselves, dry block heaters do not typically require ongoing consumables such as water or oil, which is a key advantage over traditional baths.

How accurate is the temperature control?

Grant dry block heaters are known for precise temperature control, commonly offering stability within a narrow range, which is crucial for reproducible experimental results.

Can I use this for cooling applications?

No, the Grant QBT1 is a heat block designed solely for heating applications. It does not provide cooling functionality.

This listing is for the Grant QBT1 Heat Block.

The unit is in full working condition and is ready for immediate release.

The Grant Model QBT1 Dry Block Heater With 24x10.5mm Well Block is a compact dry block heater designed for laboratory temperature-controlled heating of small sample tubes.

It’s part of Grant Instruments’ dry block heater family, used widely in molecular biology, biochemistry and general lab work for consistent incubations or reactions in tubes.

A dry bath / heat block heater that provides precise, stable heating for tubes (especially 1.5 mL Eppendorf-style tubes), without using water or oil baths.

The heat is delivered through a removable aluminium block tuned to fit a specific tube format — in this case typically 24×1.5 mL tubes.

Dry block heaters are valued in laboratory and biotech settings for reliable, uniform sample heating. Buyers typically appreciate their compact design, precise temperature control, and ease of use. When purchasing used units, checking calibration accuracy, element functionality, and power cord condition remains important. Industry sentiment favours models with consistent performance records and minimal maintenance history. Common strengths include rapid heat-up times, good temperature stability, and compatibility with standard microtubes and vials. Corrosion resistance in the heating block surface is often considered desirable for longevity.
