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

PurePlus® Polymerase Chain Reaction (PCR) consumables are made without additives so you don't need to wonder what is different about the plates, tubes, or strips you are using this week. We also test every batch for contamination by Human DNA as well as the more common tests that other suppliers offer for RNase and DNase enzymes. Many of our plates are printed with black alpha numeric reference grids to make it easier for you to keep track of your samples. We also offer optically clear caps and opaque black or white plates for Real Time PCR. And we also offer re-usable silicone sealing mats and polypropylene sealing film. Labcon PurePlus® PCR tubes, strips and plates are designed to fit many popular thermocyclers including brands like Applied Biosystems, Eppendorf, Thermo Scientific, and Bio Rad. All our PCR disposables are made from 100% virgin polypropylene and are lot tested and certified to be free of RNase, DNase, and Human DNA. Autoclavable. Our pure resin consumables are available in strips, individual tubes, plates in clear natural or colors.

PurePlus® sterile disposables, like all our other sterile products, receive valid sterilization processing compliant with ISO 11137. So unlike "pre-sterile" products from other suppliers you can use PurePlus® PCR disposables for diagnostic and regulated procedures.
