WebSeal™ 7 mm diameter Round 96-well plate Sealing mats are designed to ensure high quality data with an uninterrupted workflow for high-throughput applications using GC and HPLC/UHPLC and are ideal for regulated labs that use water and polar solvents.

• Ideal for non-regulated labs using water and polar solvents

  GC-MS and LC-MS tested

  Suitable for HPLC/UHPLC,QA/QC, and sensitive applications

  Eliminates cross contamination of samples

  Resists coring and tearing

  Superior resealability after multiple injections

These 96-well plate sealing mats are specification certified to ensure autosampler compatible physical dimensions and conform to ANSI-SLAS 4-2004 standards. WebSeal mats are manufactured from EVA (Ethylene-vinyl acetate) or pure silicone with or without a PTFE coating. Silicone mats are dry heat autoclavable with excellent chemical compatibility, and can withstand low temperatures down to −80 °C.  Ideal for verifying compound presence and quantification using detection techniques such as UV, DAD/PDA, RI, fluorescence, and ELSD.

Silicone mats: Using a silicone mat with the correct profile reduces sample and solvent evaporation during your workflows, provides better consistency, and is ideal for long-term storage. Pre-slit mats: Pre-slit mats are effective at reducing mis-injections and can be used again for confirmatory runs on the same plates without solvent loss. Their slits allow the use of pipette tips as well as multichannel pipettes. Adhesive seals: Adhesive seals are effective as a one-time seal, but cannot be used for repeat runs. The exception is our three-layer re-sealing tape without glue at the cavity area.

Level 2 products are for high-throughput applications and are suitable for regulated labs using water and polar solvents.  100% traceable through the manufacturing process.
