Cap strips provide extremely tight sealing of all Bio-Rad 0.2 ml PCR tubes and plates during thermal cycling and cold storage. Flat cap strips feature ultraclear upper surfaces that are ideal for light-based assays such as real-time PCR. Average light transmittance is 1.7-fold higher than with standard-clarity domed cap strips. Flat caps are available in strips of 8, and domed caps are available in strips of 8 or 12.
Use of a capping tool is recommended for proper seating of caps on tubes or plates.
The caps are process-sampled and tested to be free of DNase, RNase, and human DNA.
