Microseal® 'A' PCR Plate and PCR Tube Sealing Film #MSA5001


Use Microseal 'A' Film* to quickly seal any Bio-Rad PCR plate or tube. This nonadhesive film seals tightly to the majority of surfaces, from rimless polycarbonate plates to irregular surfaces. The silicone-based seal eliminates the need for a wax or oil overlay. The seals are free of DNase, RNase, and human DNA.

  • Smooth release — minimize aerosols and cross-contamination
  • Compliant sealing surface — conforms tightly to most surfaces; seals every PCR vessel offered by Bio-Rad
  • Low volume PCR — down to 5 μl in 384-well plates**, or 10 μl in 96-well plates
  • Peel away liner — keeps surface contamination-free
  • Cuts easily — for use with less than a full plate

Microseal 'A' Film is not designed for optical use. Do not use this film with real-time PCR detection systems.
