Thermo Scientific Matrix SepraSeal® and DuraSeal tube sealing solutions complement our line of innovative storage tubes. The SepraSeal capping system offers the flexibility of individual tube capping with the ability to apply 96 caps at once. New, colored SepraSeals enable different experiments and conditions to be identified at a glance. The DuraSeal option, an ultra-robust version of the SepraSeal, is available pre-installed in any of our storage tubes.
Low vapor transmission rates minimizes evaporation and water uptake
Pierceable design allows samples to be accessed without removing caps
Thermoplastic elastomer construction ensures sealing performance will not degrade, even after multiple piercings
SepraSeal caps are applied in mats of 96 caps with our SuperSealer automated cap mat applicator. After the mat is applied, simply remove the backing sheet to leave each tube individually sealed.
Sample Access Options—Individual Tube Caps are Available as:
Solid SepraSeal caps that can be removed for sample access, or pierced a single time.
Pre-split SepraSeal caps can be removed for sample access or easily pierced by liquid handling piercing needles. Due to their resealing properties, caps can be pierce even up to 200 times without increasing in sample evaporation or water uptake. Pre-split caps require much less piercing pressure than solid caps.
DuraSeal caps are available pre-installed in any of our tubes and are a thicker, permanently installed version of the pre-split SepraSeal. Ideal for use when caps will be continually pierced, DuraSeals feature a thick v-shaped lead-in that reliably guides liquid handler needles towards the split in the cap.
Cap Removal Tool: To access a single tube, or an entire row, SepraSeal caps can be quickly and easily removed with our cap removal tool. Caps can then be ejected or replaced on tubes without direct touch to avoid contamination.
Our team has a strong reputation for supporting both equipment and consumables and can demonstrate how Matrix SepraSeals and DuraSeals can meet your specific tube sealing needs.
