Arctic White sealing mat applicators ensure consistent, uniform application of ArctiSeal silicone sealing mats to 96-well and 384-well microplates — eliminating the uneven pressure and partial sealing that occurs with manual mat application. A properly applied sealing mat creates an individual well-by-well seal that is more reliable than adhesive films for repeated freeze-thaw applications and DMSO-based compound storage.
The MatCapper is a manual plate press that applies precisely calibrated downward force across the full plate footprint, seating the sealing mat evenly across all wells simultaneously. It is compact, requires no power, and operates with any standard SBS-footprint 96-well plate and compatible ArctiSeal mat. The Autocapper provides semi-automated cap application with consistent, reproducible force for labs processing higher plate volumes where operator-to-operator variation in manual application is unacceptable.
Sealing mat applicators are a low-cost, high-impact accessory for any compound management or sample storage operation using reusable silicone mats. Paired with the correct ArctiSeal mat format for your plate well geometry (round or square, 96-well or 384-well), they ensure repeatable seal integrity across every application cycle.
