Micronic’s Pierceable TPE Capmat-96 is compatible with the 0.50ml, 0.75ml, 1.10ml, 1.40ml, 2.00ml, and 2.50ml 96-well format tubes. The TPE capmat is a sheet of 96 caps with a fixed foil that can be used to seal a full rack of 96 tubes at once. Unlike tubes capped with a TPE capcluster, tubes capped with a TPE capmat cannot be individually removed from the rack—all 96 tubes are capped together.

Available in 8 different colors (natural, grey, yellow, red, pink, blue, light green, and black), the TPE capmats are pierceable and available pre-split, sterile, and DNase/RNase free.

TPE Capmats are available in natural for the following externally threaded tube sizes: 0.30ml, 0.40ml, 0.75ml, 0.80ml, 1.40ml, and 2.00ml.
