Matrix SepraSeal Septa

  • Seal down to -80°C
  • Solid or Pre-split caps
  • Different colours for fast visual sample recognition
The matrix SepraSeal tube sealing solutions are designed with the flexibility of individual tube capping with the ability to apply 96 caps at once. Caps are made out of an advanced thermoplastic elastomer which is an excellent vapor barrier for water and DMSO. SepraSeal caps will maintain a strong seal at temperatures down to -80°C, and are chemically resistant to DMSO.

Solid and Pre-split SepraSeal caps can be removed for sample access or pierced by liquid handling piercing needles. The solid caps can only be pierced a single time while pre-split caps can be pierced up to 200 times without increasing in sample evaporation or water uptake. Solid caps need more piercing pressure than pre-split caps.
