Controlled rate freezer for biological samples
In research laboratories, accurately freezing biological samples such as embryos, tissues, and blood is crucial to maintain their integrity. Traditional methods often involve hazardous expendable refrigerants, posing safety and cost challenges.

Precisely control freezing with mechanical refrigeration
The FTS BioCool™ Controlled Rate Freezer, supplied by ATS Scientific Products, offers a precise mechanical refrigeration system for freezing a wide range of biological materials. This freezer eliminates the need for hazardous refrigerants, delivering controlled and consistent temperature management from -40°C to +30°C. Its 1.5 L bath capacity and built-in magnetic stirrer ensure uniform temperatures, accommodating substantial heat loads more effectively than liquid nitrogen counterparts. User-specified ramp control with up to ten segments allows a fully customized freezing process, making it suitable for various applications such as the freezing of embryos, tissue, and blood. An optional selection of container holder racks provides further customization.
