Reveal® 3-D for Peanut offers results in just 5 minutes and can be used in virtually any environment to screen environmental swabs and clean-in-place rinses. The Reveal 3-D line of food allergen tests kits is uniquely designed to guard against oversaturation and false negative results, with results displayed in three visual lines on the lateral flow test strip. A control line assures the test is working properly, and two other lines outline nondetectable, low, and high levels of peanut.

For the separation and purification of samples of cells, macromolecular proteins, blood, body fluids, DNA/RNA, plasmids, bacteria and viruses.

Sterile TPP TubeSpin® Bioreactor vessel, 50 ml, with pH and O2 sensor spots, 1 pce.

Applicable for storing wholeblood, medicines, biological products and other laboratory products that need to be stored at 4℃. Suitable for the storage of blood and blood articles in areas that have power shortages.

The ES-20 is a compact bench–top Shaker–Incubator used for mixing of biological liquids as well as for incubation and cultivation of biological liquids according to the operator set program

A-12, adapter for work with tubes which are 12 mm in external diameter.

LN2 backup cooling system is an independent refrigeration system for a ULT freezer. When there is a loss of power or the temperature of the freezer rises to the high alarm set point, the LN2 backup system can be automatically activated to inject LN2 into the chamber to maintain the freezer temperature. The backup system operates on a rechargeable battery when there is a loss of main power.
