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.

Key Features

• Designed for bulk laboratory use with deep well, micro, and PCR plates
• Forms an airtight seal to prevent evaporation, contamination, and sample loss
• Perforations self-seal after sample access to maintain integrity
• Available pre-slit for efficient pipetting and workflow speed
• Printed alphanumeric grid for fast sample referencing
• Manufactured with no adhesives or extractables to preserve sample purity
• Temperature-resistant and automation-compatible

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
• Printed alphanumeric grid for easy reference.
• ISO9001&13485 certified
• Manufactured in 100,000 grade cleaning room with USP 6 grade raw materials   

PetriSeal™ Sealing Film

PetriSeal™ stretches and conforms to form a tight seal and is temperature resistant, waterproof and chemically resistant. It resists abrasion and puncture and blocks vapor loss while reducing the rate of gas exchange. Use PetriSeal™ with microtiter plates, Petri dishes and culture plates to prevent to entry of contaminants. The seal remains flexible down to -30°C and can withstand continuous exposure from -40°C to +77°C (with intermittent exposure up to 100°C). Tests have shown that PetriSeal™ leaves no adhesive residue even after two years.

• Colors: Blue, Clear, Red, White & Yellow
• Tape Size: 0.50 In. x 108 Ft.

ELISA, Incubation, and Short Term Incubation Sealing Films

All films on this page are designed for ELISA, Incubation, and Short Term Incubation Sealing Films. If you are looking for something specific please consult our selection guides by attribute or application on this page. All films are certified DNase- & RNase-Free.

Specific film descriptions:

1x8 MiniStrips (GP-CS1X8-400 and GPS-CS1X8-400) are less expensive than full-size sheets when using only a partial plate. Designed for use with either 1x8 strip-well ELISA plates or standard 96-well plates where rows must be selectively protected or accessed. Ideal for COVID-19 testing to seal a row of 8 wells after swabs are deposited into a deep-well plate.

General Purpose (GP-PP-100 and GPS-PP-100) polypropylene lms oer superior barrier properties to minimize evaporation and prevent well-to-well contamination. Ideal for use with polypropylene plates.

Pre-scored lm (SP2-RL-500) on a roll is a more economical and ecient alternative to rapidly seal microplates or racked test tubes; faster than applying single sheeted lm. Self-standing, non-slip supports hold the pre-scored lm roll securely in place for quick and easy bench- top dispensement. The roll unwind tension can be easily adjusted to user preference. Continuous backing liner can be torn o or fed directly into a waste basket for disposal.

The SealMate SealPlate Starter Kit (SM-KIT-SP and replacement rolls) features a re-usable dispenser and two rolls of perforated lm. The dispenser facilitates the quick and easy dispensing of lm from a roll allowing microplates to be sealed three times faster than using sheeted lms. Cost-eective replacement rolls are sold separately. Ideal for use under the hood; the SealMate dispenser minimizes lm contamination.

SealPla te (100-SEAL-PLT and STR-SEAL-PLT) minimizes evaporation, prevents well-to-well contamination and spillage. Eliminates the edge eect which can occur with plate lids (e.g. greater evaporation in the outside plate wells).

SealPlate Color Tabs (SP-IDx-100) Each end-tab features a colored dot and white writing area. An inscribed color-coded end-tab can be removed and pasted into a laboratory notebook while the other remains on the plate for identication. The lm sheet can be removed from the plate without disturbing the identication label due to the nely perforated end-tabs. Choose from 5 dierent individual colors or the assortment pack.

SealPlate 2x8 MiniStrips (SP-2X8-50 and SPS-2X8-50) are less expensive than full-size sheets when using only a partial plate. Designed for use with either 1x8 strip- well ELISA plates or standard 96-well plates where rows must be selectively protected or accessed.

ValueSeal (SP-VS-100) features smaller dimensions and a single non-perforated end-tab to provide a more cost-eective alternative to protect samples from evaporation, external contamination, dust and particulates.

DuraSeal Cling is a heat resistant, solvent-proof laboratory stretch film that can be used on a wide range of vessels.

IT CLINGS- Film can cling to itself and glass vessels.

HEAT RESISTANT- Softens at 100°C
