IceRack™ Crushed Ice Microtube Racks

IceRack™ Crushed Ice Microtube Racks are a practical solution for keeping temperature-sensitive samples stable during processing. Each rack features a removable white microtube tray that allows the blue polypropylene base to be filled with crushed ice or other cooling materials. This creates an insulated environment to protect samples from temperature fluctuations during handling.

Compatible with both screw-cap and snap-cap microtubes ranging from 0.5 to 2.0 mL, the IceRack™ is ideal for use in molecular biology, clinical diagnostics, and other cold-sensitive workflows.

A translucent lift-off lid helps maintain internal temperature while providing easy visibility and access to samples. Made from durable polypropylene, the racks are autoclavable and withstand temperatures from -80 to 135°C, offering long-term performance and versatility.

Key Features

• Designed for crushed ice or cooling beads – Ideal for cold sample processing
• Fits 0.5 mL to 2.0 mL microtubes – Screw-cap and snap-cap compatible
• Durable polypropylene construction – Withstands -80 to 135°C

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
