HyperStretch™ Sealing Film & Steri-Sheets™

HyperStretch™ is a flexible, colorless paraffin-based laboratory sealing film that molds tightly to nearly any surface. It forms secure, liquid-tight seals on a wide range of lab vessels including test tubes, centrifuge tubes, petri dishes, flasks, bottles, and beakers—making it an essential tool for everyday laboratory workflows.

Manufactured from a proprietary paraffin and polyolefin formulation, HyperStretch™ is latex-free and provides a strong yet flexible moisture barrier. The film protects sensitive samples while allowing controlled exchange of H₂O vapor, O₂, and CO₂, enabling safe off-gassing without compromising seal integrity.

Highly stretchable and self-adhering, HyperStretch™ conforms easily to glass, plastic, and metal surfaces, sticking to itself or most materials without additional adhesives. It performs reliably across a broad temperature range, including low-temperature applications down to –80°C and select liquid nitrogen (LN₂) environments, and can also be used as an overwrap for lids, caps, and stoppers to create an exceptionally airtight and liquid-tight seal.

The tennis balls are very well made.
Color: Yellow, Size: 20 PACK
Bought this bag of tennis balls for my son’s dog. He has a tennis ball launcher that he shoots and she runs to get the ball and bring it back. Perfect training toy!

Great value.
Color: Yellow, Size: 20 PACK
They bounce and they float. Color is bright. Great for my dogs. I let my dogs use these instead of the ChuckIt brand when unsupervised because they tend to get punctured.

Great color but destroy easily
Color: Orange, Size: 20 PACK
These balls are easily visible and excellent in situations where green balls may be difficult to find. I only take these balls out to play fetch. The balls only last a couple of fetch sessions before being destroyed.

Great quality and great color!
Color: Yellow, Size: 6 PACK, Color: Yellow, Size: 6 PACK
I bought this pack of six tennis balls for weekend games with my kids and some casual practice, and they’ve been great so far. The bounce is consistent, they feel solid off the racket, and they don’t go flat quickly like some cheaper balls I’ve tried before. They work well on both the court and just for backyard play.
