Slit Sealing is a method that involves sealing two or more layers of film together in the machine direction. The slit-seal technique is usually used to convert a single large tube of film into smaller tubes. For in-line operation, we have two styles of continuous slit seal units.

BAG MAKING AND FILM PROCESSING MACHINERY: TELEPHONE: 508-443-3439 EMAIL: sales@qualityconvertingproducts.com. The slit-seal technique is usually used to convert a single large tube of film into smaller tubes. The Slit Seal is a resistant, instant self-closing 96-well plate seal. The Slit Seal’s main purpose is to prevent solvent evaporation and cross-contamination.

Slit Seal, 96 well plate seal

Instant Self Closing Seal

The Slit Seal is a resistant, instant self-closing 96-well plate seal.
The adhesive-free, pre-cut slits made of silicone and PET allows easy insertion and withdrawal of pipette tips and sampling needles without catching and dragging.
The Slit Seal is proven to prevent solvent evaporation and cross-contamination. Acrylic-based adhesive is not above wells to prevent sample leaching. Seal can be easily applied and removed.
Suggested applications include automated pipetting and liquid handling, SPE, HPLC, LC/MS, cell culturing and ADME.

“We run quite a lot of samples with our mass spec, which is why some people in our lab prefer to use the autosampler plate for the samples so that they can just run 96 samples in one sitting…The plate seals are working perfectly for our application.”

Data Analysis Sheet

Differences from Silicone Mats:

• Pre-cut slits open easily, and PET layer reduces friction for very easy handling.
• Lower cost than silicone mats.

Very Effective at Preventing Evaporation:

• After 22 hours, 95% of 150 µl water will remain at 37°C
• After 22 hours, 95% of 150 µl of Acetonitrile will remain at 4°C
