PR1MA™ Stretch Multi-Purpose Laboratory Sealing Film is a premium, transparent plastic/paraffin film designed to provide a reliable and adaptable seal for a wide variety of laboratory applications. Engineered to mold to virtually any surface, it delivers secure coverage for laboratory containers such as test tubes, centrifuge tubes, petri dishes, flasks, beakers, and bottles.
Whether you're preserving sensitive biological samples or securing vessels for transport or storage, PR1MA™ Stretch is the go-to sealing solution trusted by scientists across research, pharmaceutical, academic, and industrial laboratories.
Key Benefits & Features
- Multi-surface adaptability – Seals securely to glass, plastic, and metal surfaces
- High stretchability – Stretches up to 350% for a snug, custom fit
- Self-sealing – Sticks to itself and forms a tight wrap around irregular surfaces
- Liquid-tight barrier – Ideal as an overwrap for caps, lids, and stoppers
- Flexible and translucent – Allows for easy visual inspection of contents
- RNase & DNase free – Safe for molecular biology applications
- Latex-free – Suitable for sensitive lab environments

Advanced Formulation for Sample Integrity
PR1MA™ Stretch is composed of a proprietary blend of paraffin and polyolefins, engineered to provide a flexible moisture barrier that protects delicate samples from contamination and evaporation. While delivering an airtight seal, it still permits the exchange of essential gases like oxygen (O), carbon dioxide (CO), and water vapor (HO)—ideal for cell culture and biological sample storage.

Continuous backing liner can be torn off or fed directly into a waste basket for disposal.
- Economical
- Quicker, more efficient sealing
- Provides a secure seal and is easy to remove
- Rigid polyester film features good clarity and easy handling
- Can be used as a temporary seal while awaiting further processing
Applications
- General laboratory use
- Short-term storage
- Incubation
- ELISA

EZcap™FoilStrips
An economical and more user-friendly alternative to PCR strip caps; no sore thumbs and fingers guaranteed!Application: PCR and light sensitive assays
Temp. Range: -20°C to +120°C
Proudly made in the USA! Click here for more made in America products!
Precision cut to a smaller dimension for sealing one PCR 8-tube strip or a single row of a 96-well PCR or deep-well storage plate whenever rows must be
selectively protected or accessed. FoilStrips remove easily with no splash back as can occur with strip-caps.
- Certified DNase- & RNase- free
- Each sheet contains 6 strips on a continuous liner for ease of use
- Pierceable with a pipet tip or robotic probe for direct sample recovery
- The conformable nature of foil allows for the visual verification of the seal’s security around each well
- 2.0 mil aluminum foil removes easily without tearing
Helpful Tips:
- A non-locking workstation is recommended for sample prep (e.g. 96-well round-boom plate)
- Removal of the end-tabs at the perforations is recommended before cycling
- A final sealing step is highly recommended in the thermal cycler because 8-tube strips flex during handling
- Do not fold foil around sides of tubes

AlumaSeal® CS™
With a 50 uM layer of acrylic adhesive that withstands cold storage at temperatures to -80 °C.
Unlike other sealing films in the AlumaSeal® group, AlumaSeal® CS™ sealing films are not recommended for PCR or thermocycling. A single non-perforated end tab simplifies application. Simply hold the tab and strip the backing from the body of the sealing film as it lays on the plate to avoid curling. Dimensions are 82.6 by 132.6 mm, including the single 9.5 mm end tab. AlumaSeal® CS™ sealing films are certified DNase-, RNase-, and nucleic-acid-free.
- Specially formulated for cold storage to -80 °C
- Excellent barrier properties to retard evaporation
- Easily pierceable with pipet tips or robotic probes for sample recovery
*Completing application of AlumaSeal® CS™ sealing films by pressing with the accessory plate roller assures a secure uniform seal around all wells.

- Available in a smaller cut for raised-rim and non-skirted PCR plates: ThermalSeal® Advanced
Application
- PCR
Temp. Range
- -40°C to +120°C
Helpful Tips
- Selection of the proper film size will minimize evaporation

Zone-Free™ Multilayer Film
Zone-Free™ is a multilayer film consisting of a top pierceable clear polyethylene film and a white polypropylene sublayer with 96 circular areas void of adhesive.
Application: Short-term storage and robotics
Temp. Range: -40°C to +90°C
Proudly made in the USA! Click here for more made in America products!
The white sublayer aids in the alignment of the film to the plate; alignment of opposing corner wells ensures that all 96 wells will be properly aligned. The adhesive-free zones are 9mm on center to facilitate multi-channel pipetting without adhesive fouling of pipet tips or robotic probes.
- Pierceable
- Offers excellent chemical resistance
- Samples have minimal contact with adhesive due to the adhesive-free zones
