Matrix DuraSeal Septa

  • Autoclavable
  • Strong seal down to -180°C
  • Fit on all Matrix and most other 7mm open-top tubes
  • Permanent capped
  • Pierceable
The Matrix DuraSeal Caps are made out of an advanced thermoplastic elastomer which is an excellent vapor barrier for water and DMSO. DuraSeal caps will maintain a strong seal at temperatures down to -180°C, and are chemically resistant to DMSO.

DuraSeal caps are the thicker, permanently installed version of the pre-split SepraSeal caps. The caps can be continually pierced and have a thick v-shaped lead-in that reliably guides liquid handler needles towards the split in the cap. The caps are autoclavable and fit on the Thermo Scientific Matrix and most other 7mm open-top tubes.
