Precision temperature control for microtubes and vials is essential for enzyme reactions, DNA amplification, and sample incubation. Professional laboratory thermoblocks are engineered from high-thermal-conductivity materials to ensure rapid heating and uniform temperature distribution across all samples. As a core component of our heating and cooling technology range, these interchangeable blocks provide the versatility needed for diverse molecular biology and clinical applications.
Why Choose Professional Thermoblocks?
Our curated collection of heating blocks is designed for technical compatibility and thermal stability:
- Specialized Eppendorf Tube Support: We stock Grant Block QBEO and QBE2 models, featuring 24 holes specifically designed for 0.5 ml and 2.0 ml Eppendorf tubes.
- Versatile Tube Diameters: Utilize Grant QB series blocks to accommodate various tube sizes, including 10 mm (QB10), 12 mm (QB12), 16 mm (QB16), and 18 mm (QB18) diameters at a 50 mm depth.
- High-Capacity Interchangeable Blocks: Explore the Grant QB50 for larger vessels, designed to hold 4 tubes with a 29 x 50 mm (Diam x Depth) configuration.
- Protective Thermal Covers: Use the Grant QBL2 Cover, designed for QBA2, QBD2, and QBH2 units, to maintain temperature uniformity and protect samples from ambient air fluctuations.
LabFriend supplies thermoblocks from industry-leading manufacturers specialized in high-performance thermal management:

Stable heating is the first step in successful biochemical assays; to further enhance your laboratory system, we recommend exploring these related categories:
- Cryogenic Tubes: Use Thermo Nunc or LLG polypropylene tubes for samples that require transition from heating blocks to long-term cold storage.
- Tube Racks: Organize your tubes before and after heating using LLG or Heathrow Scientific racks.
- Biobanking: Manage high-throughput heated samples using Thermo Matrix 2D barcoded tubes for permanent identification.
- Wide-Mouth Bottles: Store bulk reagents for your assays in Kartell PE bottles for secure containment.
Unsure if your assay requires a Grant QB10 block for 10 mm tubes or a specialized QBEO for Eppendorf tubes? Our team provides local technical support to help you find the correct heating solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. What is the benefit of using an interchangeable block system?
Interchangeable systems, like the Grant QB series, allow a single heating unit to accommodate multiple tube sizes (from 0.5 ml Eppendorf tubes to 29 mm diameter vessels) simply by swapping the block.
2. Why should I use a block cover like the Grant QBL2?
A cover helps maintain a stable internal micro-environment, reducing heat loss to the room and ensuring that the top of the tubes stays closer to the target temperature for better assay reproducibility.
3. Are Grant thermoblocks compatible with other brands of dry baths?
Grant QB blocks are specifically engineered for Grant's range of dry block heaters (such as the QBD and QBH series); always verify dimensions and compatibility before using them with other manufacturers' equipment.
4. What materials are these blocks made from?
Professional thermoblocks are typically constructed from high-grade aluminium, which provides the excellent thermal conductivity necessary for uniform heating across all 24 tube positions.
