Use Axygen® PCR Strip Caps for polymerase chain reaction (PCR) and real-time PCR (qPCR) experiments. Compatible with Axygen® PCR Strip Tubes (Catalog #38094) and Axygen® PCR Microplates (Catalog #38098), the cap design ensures a tight seal and reduces sample evaporation. These RNase/DNase-free, non-pyrogenic, non-sterile strip caps are available in domed, flat, or flat/ultraclear designs. The flat cap version ensures easy sample labeling, while the domed cap variation enhances the efficiency of heat transfer, and the flat/ultra-clear caps increase light transmittance by 75%.
