SepraSeal® and DuraSeal® capping systems offer a pierceable, individual tube sealing solution. They are made from thermoplastic elastomer (TPE) with colorants and are DMSO resistant.
- Low vapour transmission rates minimises evaporation and water uptake
- Pierceable design allows samples to be accessed without removing caps
- TPE construction ensures sealing performance will not degrade, even after multiple piercings
The SepraSeal® offers the flexibility of individual tube capping plus the ability to apply 96 caps at once. With a choice of available colours, different experiments and conditions can be identified at a glance.
DuraSeal® is a permanently-installed, ultra-robust version of a SepraSeal® that enables storage down to the vapour phase of liquid nitrogen. It is ideal for applications requiring repetitive piercings. The V-shape of the DuraSeal® reliably guides liquid handling needles to the same location repeatedly with same self-healing capability as a SepraSeal®.
