IsoFreeze® MCT Color-Change Racks

Leave the Ice Buckets Behind!
IsoFreeze Color-Changing Racks take the guesswork out of sample preparation!

Using proven IsoFreeze temperature maintenance technology, the filled racks maintain a cool (refrigerator) environment on the bench or the workstation platform. This helps maintain a stable environment for PCR reagents, cells, enzymes, or other temperature-sensitive reagents. Industry Standard format tubes, strips, and 96 well plates, in both standard and low profile well shapes, are accommodated and are efficiently cooled in PCR, QPCR, and many other applications.

IsoFreeze PCR Racks are manufactured using polypropylene containing temperature-dependent color-change dye giving at-a-glance temperature indication for each well. There is a dramatic change to a contrasting color at 7ºC. IsoFreeze gel technology means the wells will stay cool for up to 4 hours, depending on ambient temperature and other factors.

• Available in 2 color changing formats
• Material: Rugged polypropylene and inert gel
• Maintains temperature of less than 4°C for up to 2.5 or 3.5 hours depending on Rack
