ILP PTFE Coated Sealing Mats

ILP PTFE Coated Sealing Mats are engineered from premium medical-grade silicone and coated with PTFE (polytetrafluoroethylene) for unmatched chemical resistance and airtight sealing performance. These high-quality sealing mats are ideal for laboratories requiring secure sample storage, especially in volatile organic compound (VOC) environments or chromatography workflows.

Designed to fit tightly into deep well plates, the mats effectively prevent evaporation, eliminate cross-contamination, and reduce aerosol or pathogen venting. Their self-sealing perforations allow repeated pipette penetration without compromising sample integrity, perfect for automated or manual liquid handling.

These mats are thermally stable and suitable for use across a broad temperature range, making them ideal for incubation, high-temperature storage, or exposure to harsh solvents. Resistant to coring, tearing, and leaching, they ensure no particulate contamination enters your wells.

Fully autoclavable, reusable, and certified RNase-, DNase-, and Pyrogen-free, ILP’s PTFE-coated mats are the preferred choice for chromatography, high-throughput screening, and demanding lab environments.

Key Features

• PTFE-coated for enhanced corrosion and chemical resistance
• Pre-slit options available for easy pipetting and reduced mis-injection
• Perforations self-seal after use, maintaining airtight integrity
• Ideal for chromatography and solvent-sensitive applications
• Free from RNase, DNase, and Pyrogens
• Reusable and autoclavable; no adhesives or extractables

ILP Sealing Mats - Bulk

Silicone Sealing Mats are engineered for reliable, airtight sealing of deep well plates, microplates, and PCR plates in both automated and manual laboratory workflows. These high-performance mats are ideal for high-throughput screening, sample storage, and protocols requiring frequent plate access.

Made from high-quality, chemically resistant silicone, these mats form a tight seal that helps prevent evaporation of VOCs, minimize sample loss, and eliminate cross-contamination, even during vigorous automation processes. They are thermally stable, making them suitable for incubation and storage in high-temperature environments or use with aggressive solvents.

Each mat includes self-sealing perforations, which maintain an airtight closure after pipette penetration, reducing the risk of aerosol exposure or pathogen venting. Available in scored or pre-slit formats for easy pipetting and reduced mis-injection, with optional PTFE-coated versions offering enhanced resistance to harsh chemicals. A printed alphanumeric grid is included on each mat for easy sample identification.

These mats are sold in bulk quantities, ideal for labs with high usage needs. Choose bulk packs to save time, reduce packaging waste, and ensure uninterrupted workflow.

Nest Sealing Mats for 96 Well Plates

Nest silicon sealing mats are designed for 96-well storage. Produced from the highest quality research-grade silicone, they are specially designed to provide a positive and airtight seal.

Mats fit tightly into wells preventing evaporation of VOCs, sample loss in storage, cross contamination, and reducing the risk of aerosols and pathogens venting during the automation process. They work in a wide range of temperatures for incubation and storage applications; especially for storage at higher temperatures or for applications involving aggressive solvents.

These seals go well with automation as well as manual laboratory protocols. Often used in high-throughput applications or those involving accessing the sample through the cover multiple times.

High-quality silicone resists coring and tearing, reducing the risk of mat particulate entering the well. Well perforations will seal themselves after penetration, ensuring an airtight closure. These mats are chemically resistant and reusable, containing no adhesives or extractables to contaminate samples.

• High-quality silicone, resists coring and tearing reducing the risk of mat particulate entering the well
• Autoclavable
• May be reused after a 10% bleach wash and ethanol rinse protocol
