Thermo Fisher Scientific Inc. has introduced new and improved AcroSeal® packaging designed for air- and moisture-sensitive Acros Organics reagents and solvents. The new packaging better maintains chemical integrity, reducing the cost associated with purchasing replacement products.
Ideal for aggressive solvents and reagents, the adhesive-free AcroSeal packaging significantly reduces the rate of moisture uptake and the risk of contamination in tests comparing tetrahyrofuran in the new AcroSeal packaging and in a competitor’s packaging. It features an innovative, patent-pending quadrant septum, developed from a polymeric elastomer coated with inert fluoropolymer. With multiple layers, the septum holds its shape and forms a superior re-seal after puncturing to withdraw chemicals. With a large surface area, the convenient quadrant-style screw cap provides easier access to larger volumes of solvent and supports multiple punctures to the septum, further minimizing contamination risk.
Extra-dry solvents, including methanol, acetonitrile, dichloromethane and methyl sulfoxide, are available in the new and improved AcroSeal packaging. This extends across three different grades: standard grade solvents, which are suitable for most applications; molecular sieves grade solvents, which have been stored over molecular sieves for prolonged shelf life; and finally supreme grade solvents, which have been filtered through 0.2 micron filters. The new packaging will be available for other Acros Organics product groups in the near future.
