Our optical caps are semi-dome thin-walled 8-cap strips. These caps are optically flat and have parallel area on top, which allow performing Real-Time qPCR experiments. Their extremely clear glass-grade area equals the performance properties of optical seals. When combined with our qPCR plates they exhibit better closure than other brand, thus less evaporation. Please refer to our compatibility table to use the correct caps compatible with your Real Time thermocycler.
