Description
Product Overview
The Dual-Size Aluminum Cooling Block from Lowhigh is engineered to meet the demanding needs of modern laboratories, home‑brew enthusiasts, and field researchers alike. Constructed from high‑purity aluminum, the block offers superior thermal conductivity, allowing rapid temperature equilibration when placed in an ice bath or refrigerated environment. The anodized surface provides a rust‑resistant finish that endures repeated cleaning cycles with water, alcohol wipes, or mild detergents, ensuring long‑term durability. With a compact footprint of approximately 4.5″×3″×1.2″, the cooler fits comfortably into standard freezer compartments, incubators, or benchtop workspaces without sacrificing capacity.
Designed with a dual‑size well layout, the block accommodates 24 wells sized for 1.5 ml and 2 ml centrifuge tubes as well as 36 wells for 0.2 ml PCR tubes. The universal spacing prevents tube caps from touching, reducing the risk of cross‑contamination and simplifying sample handling. Each well is precisely machined to provide a snug fit, minimizing air gaps and maximizing thermal transfer efficiency. The block is reusable, eliminating the need for disposable ice packs and reducing overall laboratory waste.

Usage
Whether you are conducting short‑term enzymatic reactions, preparing reagents for molecular biology protocols, or simply chilling beverages for a field experiment, this cooling block adapts to a wide range of scenarios. In a molecular biology lab, the 0.2 ml PCR tube wells enable rapid cooling of reaction mixes, preserving enzyme activity and improving reproducibility. In a chemistry teaching environment, the larger wells accommodate 1.5 ml and 2 ml centrifuge tubes for quick temperature control during precipitation or crystallization steps. Home brewers can use the block to chill fermentation vessels, while cosmetics formulators benefit from the ability to keep sensitive ingredients at low temperatures during mixing.
The block’s lightweight design (approximately 1.27 lb) makes it easy to transport between workstations, field sites, or classroom benches. Its compatibility with standard ice‑bath containers means you can achieve sub‑zero temperatures without specialized equipment. Simply fill a larger container with ice and water, submerge the block, and allow the aluminum to draw heat away from your samples within minutes. The block also works well in refrigerated freezers for longer‑term storage, maintaining a consistent temperature that protects temperature‑sensitive samples.

FAQ
Can the cooling block be used with standard laboratory freezers?
Yes, the block’s dimensions are designed to fit typical laboratory freezers. It can be placed directly on a freezer shelf to maintain low temperatures for extended periods without the need for additional ice.
Is the anodized surface safe for contact with biological samples?
The anodized coating is chemically inert and does not leach substances that could interfere with biological assays. It is safe for use with a wide range of samples, including PCR reactions and cell culture media.
How do I clean the cooling block after use?
Cleaning is straightforward: rinse the block with distilled water, wipe with an alcohol‑based wipe or mild detergent, and allow it to air‑dry. The anodized surface resists staining and corrosion, making routine maintenance easy.
What is the warranty period for this product?
Lowhigh provides a one‑year limited warranty covering manufacturing defects. Should any issue arise within this period, contact our support team for a replacement or repair.
Can I use the block for applications other than cooling?
While primarily designed for cooling, the block’s excellent thermal conductivity also makes it suitable for gentle heating when placed in a warm water bath, allowing controlled temperature adjustments for certain protocols.
