24 Well+36 Well Aluminum Cooling Block for 0.2/1.5/2 ML Tube

Description

Product Overview

Designed for demanding laboratory environments, the 24 Well+36 Well Aluminum Cooling Block from SLIYXTWIO combines precision engineering with durable construction. The block is machined from high‑grade aluminum that has been treated with oxidation electrophoresis coating, a process that creates a hard, corrosion‑resistant surface while preserving excellent thermal conductivity. Each of the 24 larger wells (11 mm diameter, 21 mm depth) and 36 smaller wells (6 mm diameter, 14 mm depth) is precisely drilled to accommodate standard 0.2 mL, 1.5 mL, and 2 mL tubes, allowing simultaneous cooling of multiple samples. The overall dimensions of the block measure 115 mm × 75 mm × 30 mm, and the compact footprint fits easily on most bench tops and incubators. A thermally insulating silicone sleeve surrounds the aluminum body, reducing heat loss and providing a non‑slip grip for safe handling during temperature‑sensitive procedures. The block’s design supports rapid temperature equilibration, making it ideal for applications that require consistent cooling from –20 °C to ambient conditions.

Usage

The cooling block is suited for a wide range of laboratory workflows, including enzyme assays, PCR preparation, cell culture media cooling, and analytical chemistry sample handling. Researchers can pre‑cool the block at –20 °C for four to six hours, then maintain sample temperatures for one to two hours at room temperature, ensuring reaction stability and reproducibility. Its versatile well sizes accommodate both micro‑tubes and larger vials, making it a flexible tool for multi‑step protocols. The silicone sleeve not only protects the aluminum from accidental impacts but also offers a comfortable grip when moving the block between cold storage and workstations. Because the block is compatible with standard laboratory racks and incubators, it integrates seamlessly into existing bench layouts without requiring additional accessories. Users in academic, biotech, and pharmaceutical settings will find the block especially valuable for high‑throughput screening where uniform cooling across many samples is critical.

Why Choose Us

SLIYXTWIO has a reputation for delivering laboratory equipment that meets rigorous quality standards, and this cooling block is no exception. The oxidation electrophoresis coating process is performed in a controlled environment, guaranteeing a uniform protective layer that prevents rust, corrosion, and aging even after repeated freeze‑thaw cycles. The aluminum core provides superior heat transfer compared with plastic alternatives, reducing cooling time and improving temperature stability. The included silicone sleeve is engineered from medical‑grade silicone, offering both thermal insulation and a non‑slip surface that enhances user safety. Each block undergoes a full functional test before shipment, confirming that all wells meet dimensional tolerances and that the block achieves the specified cooling performance. In addition, SLIYXTWIO offers responsive technical support and a one‑year warranty, giving customers confidence that any issues will be addressed promptly.

FAQ

Can the cooling block be used with tubes larger than 2 mL?

The block is optimized for standard 0.2 mL, 1.5 mL, and 2 mL tubes. Larger tubes may not fit securely in the wells, which could affect temperature uniformity. For larger volumes, we recommend a block designed specifically for those dimensions.

How long does it take for the block to reach –20 °C?

When placed in a standard laboratory freezer set to –20 °C, the block typically reaches the target temperature within 4 to 6 hours. This time can vary slightly depending on freezer load and ambient conditions.

Is the silicone sleeve replaceable?

Yes, the silicone sleeve is a separate component that can be removed and replaced if it becomes worn or damaged. Replacement sleeves are available from SLIYXTWIO and are designed to fit the exact dimensions of the cooling block.

What cleaning procedures are recommended?

To clean the block, wipe the aluminum surface with a soft, lint‑free cloth dampened with mild detergent and distilled water. Avoid abrasive cleaners or solvents that could damage the protective coating. The silicone sleeve can be cleaned with the same solution and then rinsed thoroughly before drying.

Does the block interfere with magnetic stirrers?

The block’s aluminum composition is non‑magnetic, so it does not interfere with magnetic stirrers. However, the silicone sleeve adds a thin insulating layer, so magnetic coupling strength may be slightly reduced compared to a bare metal surface.
