Thermo Scientific XBF40D General Purpose Blast Freezer

Rapidly freeze plasma with the new Thermo Scientific XBF40D-MD -40°C Blast Freezer - a breakthrough sample preparation device for use prior to cold storage. Your freezer is not a sample preparation device. Ultra-low and laboratory-grade freezers are designed to maintain samples at cold temperatures for long-term storage. They are not designed for and do not have the speed or refrigeration capacity to rapidly freeze plasma and other critical storage. Using the new XBF40D-MD for rapid cooling reduces the stress on your sample storage freezer, and freezes your plasma quickly and efficiently.

Features and benefits

Prepare product for storagein a fraction of the time

These examples show how much time you can save by using the XBF40D to bring any critical sample, or volume, to storage temperatures.

As shown below, a test of 5L bottles filled with 3.5L of tap water reached 0°C on average of 100 minutes and -30°C on average of 600 minutes. A grouping of 2mL vials reached 0°C in 5 minutes and -30°C in 25 minutes.

In a test comparing freezing times between the XBF40D and a -80°C ultra-low freezer, a group of 5L bottles on average reached -70°C in the XBF40D 75% faster than an ultra-low freezer.
