Detail
Overview
Non-woven gas permeable seal that limits evaporation. The seal is peelable, pierceable; suitable for cell culture and seed & insect storage too.
Heat sealing offers a 100% effective method for plate sealing for a complete seal integrity, as well as being quick and cost effective
Our Gas PermASeal Heat Seal is made from a non-woven material and is designed for use in cell culture, due to its porous nature
The seal is compatible with polypropylene and polystyrene
It can be removed by peeling, or it can be pierced with a pipette tip manually, using a liquid handling robot.
Gas PermASeal Heat Seal can be utilized for effective overnight incubations, during which it demonstrates significant reductions in evaporation compared to lids
It can also be used for insect and seed storage as it enables gas exchange, whilst providing an inert surface with no adhesive to interfere with the well contents
This seal is available as sheets, for use with manual and semi-automated sealers, such as our HeatASeal 500 Sealing Machine
Also available in multiple roll formats compatible with specified automated heat sealers, such as our Wasp or Chameleon XT

Product Info
The Permagen 384-well post magnet plate was designed for use in manual or automation applications for Low Elution high throughput PCR
Magnetic beads are pulled midway up onto well wall to help eliminate accidental bead pellet disruption and to achieve lower volumes
Features include solid aluminum alloy construction and hard coat anodized finish for years of trouble-free use, compatible with any magnetic beads, and integrated cushion base to help aid in robot/ consumable inconsistencies
Dietary fiber can generally be described as the carbohydrate content of food that is not digested in the human small intestine. It passes into the large intestine where it is partially or fully fermented. These characteristics of dietary fiber are associated with its numerous well documented health benefits.
Dietary Fiber is a mixture of complex organic substances, including hydrophilic compounds, such as soluble and insoluble polysaccharides and non-digestable oligosaccharides, as well as a range of non-swellable, more or less hydrophobic, compounds such as cutins, suberins and lignins. The procedures for the determination and analysis of total dietary fiber as outlined in our assay protocol are based on the methods of Lee et al.1 and Prosky et al.2,3 (AOAC 991.43, AOAC 985.29, AACC 32-07.01 and AACC 32-05.01). However, the enzymes in the Megazyme Total Dietary Fiber Kit can also be used in other dietary fiber analytical methods such as AACC Method 32-21.01 and AACC Method 32-06.01.

Two separate methods are described in the associated assay protocol:
METHOD 1: DETERMINATION OF TOTAL, SOLUBLE AND INSOLUBLE DIETARY FIBER Based on AOAC Method 991.43 “Total, Soluble, and Insoluble Dietary Fiber in Foods” (First Action 1991) and AACC Method 32-07.01 “Determination of Soluble, Insoluble, and Total Dietary Fiber in Foods and Food Products” (Final Approval 10-16-91).
METHOD 2: DETERMINATION OF TOTAL DIETARY FIBER Based on AACC method 32-05.01 and AOAC Method 985.29.
