Performance Level 2 Mats – for High-Throughput Applications 

• 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
• Ideal for verifying compound presence and quantification using detection techniques such as UV, DAD/PDA, RI, fluorescence, and ELSD
• Eliminates cross contamination of samples
• Resists coring and tearing
• Superior resealability after multiple injections
• 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

Reduce the risk of mis-injection – To seal your plates correctly, it’s important to use the right mat

• 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.
