Microsoft RL-PLT-01 Excel Scientific Multiwell Plate Roller

The Excel Scientific RL-PLT-01 Multiwell Plate Roller is a benchtop accessory designed for one specific but critical laboratory task: applying sealing films securely and uniformly to multiwell plates. Proper sealing is essential in plate-based assays and storage to prevent sample evaporation, cross-contamination between wells, and environmental exposure. This roller is compatible with 96-well, 384-well, and 1536-well plate formats, making it versatile enough to serve across a range of common experimental workflows including PCR preparation, compound storage, and cell-based assays.

The handheld design requires no power or calibration — the user simply rolls it across the sealing film after it has been placed on the plate, applying even pressure to ensure a complete seal around each well. This eliminates the uneven adhesion and trapped air pockets that can occur when seals are pressed on by hand. While automated plate sealers exist for very high-throughput laboratories, this manual roller provides a reliable and cost-effective solution for labs that process plates at moderate volumes and need consistent results without investing in powered equipment.
