SealPlate® SealMate™ Rolls

For Fast and Efficient Microplate Sealing. The SealMate SealPlate Starter Kit features a re-usable dispenser and two rolls of perforated film.
 
The dispenser facilitates the quick and easy dispensing of film from a roll allowing microplates to be sealed three times faster than using sheeted films. Cost-effective replacement rolls are sold separately. Ideal for use under the hood; the SealMate dispenser minimizes film contamination.

• Environmentally friendly; no paper liner to remove and discard; utilizes approximately 72% less material than SealPlate sheeted film
• Each sheet is separated by an adhesive-free, perforated, color-coded green band
• The smooth lower surface of the dispenser can be used to seal the film to the plate
• Dispenser protects unused seals from contamination
• Lower support prop prevents dispensing bill from contacting surfaces to prevent contamination
• Replacement rolls can be easily installed by releasing the locking clasps on the dispenser

• General laboratory use
• Short-term storage
• Incubation
• ELISA

• -40°C to +120°C

General Purpose Sealing Film

• Certified DNase- & RNase- free
• Features good chemical resistance
• Provides a very secure seal to minimize evaporation, but is slightly harder to remove than SealPlate films
• Less rigid polypropylene film reduces aerosols upon removal
• Specially formulated adhesive minimizes plate residue
• Can be used as a temporary seal while awaiting further processing

SealPlate® Sealing Film

Industry Standard for Sample Protection.
 
SealPlate® minimizes evaporation, prevents well-to-well contamination and spillage. Eliminates the “edge effect” which can occur with plate lids (e.g. greater evaporation in the outside plate wells).

• Provides a secure seal and is easy to remove
• Rigid polyester film features good clarity and easy handling
• Can be used as a temporary economical seal while awaiting further processing
• Features two end-tabs with perforations

AlumaSeal® II™ Easy-to-pierce Aluminum Foil Seal
 
Easy-to-pierce, Medical Grade Acrylic Adhesive. 

FoilSeal™

AdvanceSeal™ Sealing Film

AdvanceSeal™ Sealing Film offers high-performance sealing solutions for laboratory microplates, designed for use with automated roll format heat seal applicators. Available in two configurations, pierceable foil heat seal and peelable transparent heat seal, this film is ideal for demanding applications such as PCR, compound storage, and high-throughput screening.

Pierceable Foil Heat Seal

Engineered for automated workflows, the pierceable foil heat seal delivers a hermetic seal that protects sample integrity by being highly impermeable to light, gas, and moisture. Its non-adhesive design ensures that no residue is left on pipette tips, reducing the risk of cross-contamination.

Key Features

• Pierceable with pipette tips or robotic probes
• Ideal for low-volume and sensitive samples
• Strong microbial barrier for sterile applications
• Excellent chemical resistance (e.g. DMSO)
• Free of detectable RNase, DNase, human DNA, PCR inhibitors, and endotoxins (PCR Certified) 

Peelable Transparent Heat Seal

The peelable transparent heat seal provides superior evaporation protection and is easily removed without leaving residue, making it suitable for workflows that require easy sample access post-processing.

Key Features

• Clear, peelable design allows for visual inspection of samples
• Easy removal without damaging the plate surface
• Effective in temperature ranges from -80°C to +105°C
• Compatible with polypropylene, polycarbonate/polypropylene, and polystyrene plates
• PCR Certified: Free of detectable DNase, RNase, and human DNA
• Compatible with leading heat sealers:
• Kbiosystems, Porvair®, Azenta, ThermoFisher®, Agilent PlateLoc™                            

Ideal For

• PCR and qPCR
• Sample storage (short- and long-term)
• Compound screening
• Automation and robotic systems

Storage Recommendation
 

For optimal shelf life and performance, store at 137°F ±10°F with 50% relative humidity.

eXTReme™ Seal Extra Strong Sealing Film

eXTReme™ Seal features an extra-strong thick adhesive to minimize evaporation, yet removes easily without leaving residue on the plate.

Features chamfered corners to eliminate plate overhang for robotics applications and tight storage conditions.

• Certified DNase- & RNase- free
• Ideal for use with raised-rim and non-skirted PCR plates
• Available in a larger cut for flat-top semi-skirted and full-skirted PCR plates: eXTReme™ Seal, Large

Application

• PCR
• Robotics

Helpful Tips

• Selection of the proper film size will minimize evaporation
• The film should not overhang or ride up the wall of a raised-rim plate
• More complete coverage of skirted flat-top plates will reduce evaporation in the outer wells
• End-tab removal before thermal cycling is highly recommended

Parafilm® M Sealing Film

Flexible, stretchable lab film for moisture-resistant sealing.

Parafilm® M Sealing Film is a trusted solution for sealing and protecting labware, widely used in scientific, medical, and industrial settings. This semi-transparent, thermoplastic film is made from a blend of polyolefins and waxes, offering two-way stretch and excellent sealing capabilities on various surfaces, including test tubes, flasks, beakers, and petri dishes.

With the ability to stretch over 200% of its original size, Parafilm® M conforms tightly to irregular surfaces and forms a strong, moisture-resistant barrier that prevents evaporation and contamination. It is odorless, non-toxic, and resistant to acids, alkalis, and organic solvents, making it ideal for sensitive applications.

Available in various sizes, Parafilm® M is an essential lab consumable for preserving sample integrity and minimizing environmental exposure.

Key Features

• Forms a tight, moisture-resistant seal that adheres to glass, plastic, and metal
• Highly stretchable, extends over 200% to fit irregular shapes
