Plate Sealing & Closures

Arctic White plate sealing closures protect microplate wells from evaporation, cross-contamination, and compound degradation across all standard SBS formats. The ArctiSeal™ line of silicone sealing mats creates individual plug seals in each well—delivering superior re-sealability compared to adhesive films, critical for compound libraries requiring repeated access over months or years. Available in format-matched configurations for 96 round-well, 96 square-well, 384-well, and 48-well plates, with silicone and PTFE-coated variants for DMSO-based compound libraries where chemical inertness is essential.

The collection also includes adhesive pattern sealing films for selective well access and thermal sealing foils for permanent closures. Pair with a MatCapper or Autocapper sealing mat applicator for consistent, reproducible mat seating.
