Waters offers a wide range of 96-well plates, 384-well plates and accessories for use as sample plates in autosamplers and as collection plates for sample preparation extracts.
Polypropylene Cap Mats with high chemical resistance are available for 96-well plates
Silicone / PTFE Cap Mats are available for 96-well plates and 96-well plates with glass inserts. The mats come in slit and non-slit versions. The slit versions are recommended for use in autosamplers for proper venting and accuracy of the sample draw with excellent resealing characteristics. The non-slit versions are recommended for long term sample storage.
Clear Polyester Heat Seal can be used with most sample solvents and buffers over a -80°C to 80°C temperature range. A heat sealer is required to apply the seals.
Aluminum Foil Heat Seal is made from a polyester/aluminum laminate. The addition of the aluminum layer reduces the gas permeability of the seal. For longer term storage, the aluminum foil heat seal is a better choice to reduce evaporative loss. The seal can be used at temperatures from -200°C to 90°C. A heat sealer is required to apply the seals.
Adhesive Seal is a polyolefin film with a synthetic rubber adhesive. This seal is ideal for use with protein and peptide samples in buffers. The adhesive is resistant to small concentrations (0% to 30%) of polar organic solvents and can be used from -80°C to 80°C. The seal requires no heat sealing equipment to apply.
