Metabolic Cage Rack, Vertical, 12-Cage Rack
When preparing PCR samples in plates, strips and single tubes, PCR solutions must be kept cool as warming may result in unspecific PCR products. Our new IsoFreeze® PCR Racks prevent sample damage caused by premature warming. Using IsoFreeze® PCR Racks provides considerable advantages: Once pre-chilled, the rack can maintain the PCR sample temperature at approximately 4°C for up to 3 hours in ambient conditions. If sample temperatures exceed 7°C, the rack visibly changes color from purple to pink to alert users. The racks are sold in a pack of two so that a warm rack can be conveniently exchanged for a chilled rack during prolonged use.
