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: 

Consistently cooled samples – when the product leaves the optimal temperature range (at 7°C), the rack's cooling block undergoes a clearly visible colour change – from purple to pink. 

With the lid closed, the sample temperature can be maintained at abt. 4°C for a standard ambient temperature for 3 hours. 

The rack with 8x12 wells in a 96-well format accommodates PCR plates, strips and individual tubes (0.2 mL)
