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

DryChill™ Ice-free Cooling Block

The DryChill™ cooling blocks are designed to store samples safely on the lab-bench without sample degradation due to temperature increase or fluctuation. Unlike traditional ice buckets, these blocks do not require any ice and are uniquely designed to minimize condensation, resulting in a convenient, mess-free cooling.

Each DryChill™ Cooling Block utilizes a proprietary gel refrigerant, designed to maintain cold (but not freezing) temperatures for extended time periods. Once the block temperature begins to warm, the visual indicator alerts the user by changing from purple to pink.

Four blocks are available for accepting a wide variety of commonly used research tubes and plates.

• Ice-free, stable cooling for sample tubes
• Unique design reduces condensation
• Maintains 4°C for up to +200 minutes
• 4 sizes for various tubes up to 50 mL
• Visual temperature indicator

Forensic MicroSpin

• Forensic MicroSpin is a valuable device for the extraction of DNA from crime scene samples.
• Forensic MicroSpin is specifically manufactured to prevent DNA or RNA contamination of the device prior to use.
• The receiver tube can be capped to protect the sample for storage or freezing

Spec and Instructions:

• The device has a filter unit, and a 2ml graduated micro centrifuge tube with an attached cap.
• The filter unit has an integral perforated bottom that filter acts like a strainer and allows fluids to pass but retains small cloth samples in the filter unit.
• A cloth sample from the crime scene is cut into small pieces and inserted in the filter unit.
• Add appropriate solvents or buffers to the cloth sample in the filter unit that will permit extraction of DNA.
• The filter unit is then placed into the 2ml microcentrifuge receiver tube, and the entire assembly is centrifuged in a microcentrifuge as indicated in the DNA extraction protocol being used by the forensic laboratory.
• Following centrifugation, the filter unit is removed from the filtrate receiver tube, and the cellular debris in the bottom of the tube can be DNA fingerprinted by the forensic technician.
• Maximum centrifugal force is 20,000 x g. Non-Sterile.
• Includes Filter Unit & 2.0ml Receiver Tube

These Items are Back in Stock!

• Sterile
• Certified DNAse, RNAse, pyrogen, and DNA-free.
