Benchmark Scientific DC0650 Dry Chill Ice-Free Cooling Block

Description

Product Overview

The Benchmark Scientific DC0650 Dry Chill Ice-Free Cooling Block is engineered to deliver precise, short‑term cooling for a variety of laboratory applications. Constructed from high‑impact polymer with a sealed internal chamber, the block maintains a stable temperature of up to 4 °C for approximately 100 minutes without the need for ice or external refrigeration units. Its compact footprint of 5.9 × 4.2 × 3.8 in. (14.7 × 10.5 × 9.5 cm) and lightweight design (2.2 lb) allow it to fit easily on benchtops, inside incubators, or on portable workstations. The block accommodates six standard 50 ml centrifuge tubes, each seated in individual recessed wells that provide uniform cooling across all samples. The product dimensions of 10 × 9 × 7 in. for the packaging ensure safe shipping, while the model number DC0650 clearly identifies the specific configuration.

Usage

Designed for researchers who require short‑term temperature control, the DC0650 excels in molecular biology protocols such as enzyme reactions, PCR setup, and sample preparation where maintaining a cool environment is critical. It is equally suitable for chemistry labs performing temperature‑sensitive syntheses, as well as field scientists who need a portable cooling solution for on‑site sample preservation. The block can be pre‑cooled in a standard laboratory refrigerator before use, and once removed, it sustains the target temperature without additional power sources, making it ideal for time‑critical workflows, batch processing, and educational laboratory demonstrations. Its user‑friendly design requires no assembly; simply insert the tubes, and the block begins delivering consistent cooling immediately.

FAQ

How long does the block stay at the target temperature?

The DC0650 is rated to hold a temperature of up to 4 °C for approximately 100 minutes after being pre‑cooled, provided the ambient conditions are within typical laboratory ranges.

Can the block be used with tube sizes other than 50 ml?

While the recessed wells are optimized for standard 50 ml tubes, the block can accommodate slightly smaller tubes as long as they fit securely within the wells. Larger tubes may not achieve uniform cooling.

Is any external power required during operation?

No external power source is needed once the block has been pre‑cooled. The insulated polymer construction retains the cold temperature, allowing the block to function independently for the full hold time.

What warranty coverage does Benchmark Scientific provide?

The product comes with a two‑year limited warranty that covers any manufacturing defects. Customers can contact Benchmark Scientific support for warranty claims, replacement parts, or technical assistance.

How should the block be cleaned after use?

Wipe the exterior with a soft, damp cloth and mild detergent if needed. Avoid submerging the block in water or using abrasive cleaners, as this could compromise the sealed internal chamber.
