Heat sealing offers a 100% effective method of plate sealing, for complete seal integrity, as well as being quick and cost effective.
Our Individual Access Peel Heat Seal is a laminate seal compatible with polypropylene plates, featuring 96 individual foil seal spots or 12 strips of individual spots on a removable backing.
These seals result in individually sealed tubes/strips, and they can be removed from polypropylene plates by peeling, even with a plate which has been removed directly from -80°C storage.
Individual Access Peel Heat Seal forms a complete seal to a plate enabling very low temperature uses, including very low temperature storage, and high temperature uses, such as PCR (when used with a pressurized heated lid).
The seal demonstrates moderate solvent resistance and can be utilized for short term compound storage at room temperature.
This seal is available as sheets, for use with manual and semi-automated sealers, such as our Semi-Automated Sheet Heat Sealer (using the 59-2005 Individual Access adapter).

| Method recognition: | Methods based on this principle have been accepted by MEBAK, OIV, EU, ISO2963, AOAC and IFU22 (NOTE: If the enzyme oxaloacetate decarboxylase is present in the sample, some of the oxaloacetate product is converted to pyruvate. Therefore, to ensure citric acid is measured quantitatively, D-lactate dehydrogenase (D-LDH) is employed to efficiently convert any pyruvate produced into D-lactate and NAD+). |
The Citric Acid test kit is a flexible and simple method for the rapid and reliable measurement and analysis of citric acid (citrate) in foods, beverages and other materials.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).

Advantages
The Citric Acid test kit is a flexible and simple method for the rapid and reliable measurement and analysis of citric acid (citrate) in foods, beverages and other materials.
This kit provides a rapid spin column method for the purification of total DNA from a broad spectrum of bacteriophages propagated in bacteria grown in liquid cultures. The DNA is isolated without the use of phenol, chloroform or cesium chloride banding procedures. The spin-column based procedure is rapid and can be completed in less than 45 minutes. The kit is highly efficient for processing small volumes of phage supernatant (500 µL – 1 mL) and with the optional DNase and Proteinase K treatments phage DNA yields are maximized while host DNA contamination is minimized. Purified total phage DNA is of the highest integrity, and can be used in a number of downstream applications including PCR, qPCR, Restriction Fragment Length Polymorphism (RFLP), sequencing, cloning, Southern Blot and more.
