Envirocheck® contact slides are widely used to check critical control points (CCP's) within the HACCP (Hazardous Analysis Critical Control Point) for the microbiological hygiene control of surfaces in production lines and equipment. Additionally these slides can be used to check the microbiological hygiene status of liquids. The use of a variety of media on the contact slides allows the detection of organisms from liquids as well as surfaces. These slides provide semi-quantitative results for five different parameters. Easy incubation in the Cultura® mini incubator also reduces the necessary workspace. Each contact slide is packed in a PC tube, which protects the agar media against contamination before and after sampling.

Dip slides for microbiological monitoring of surfaces and in liquids. Each slide has media on both sides, with a choice of the same medium, or two different media on the two sides of the slide. This allows sampling of two surfaces with every slide. Testing with dip slides is a safe, reliable, economical and fast indicator of the presence of microorganisms. Dip slides, with a push cap, have a larger contact area.

PolyFreeze is a water-soluble support matrix and a form of embedding medium for frozen sectioning. PolyFreeze sections flawlessly at routine frozen specimen thickness of 5-6 μ and leaves no slide residue. It provides for -20 ºC cryostat sectioning in rapid set embedment. This medium freezes quickly supporting the tissue for sectioning at 3 mm and up with no cracking of the matrix at temperatures from -8 °C to -25 °C.

RNA-Solv® Reagent is a one reagent system for the isolation of total RNA from cells and tissues. The reagent, a single-phase solution consisting of phenol and guanidine isothiocyanate, is a modification of the single-step RNA isolation method developed by Chomczynski and Sacchi. The sample is homogenised and lysed in RNA-Solv® Reagent, which maintains the integrity of the RNA while disrupting and denaturing endogenous RNases and other cellular components. Extraction of the lysate with chloroform further denatures proteins and separates the mixture into an organic and an aqueous phase. RNA remains exclusively in the aqueous phase, and is subsequently recovered by isopropanol.

When sectioning frozen tissue for rapid surgical biopsy diagnosis or for research (typically in Histochemistry), the tissue sample must be firmly attached to the microtome stage or chuck. Embedding material such as OCT are preferred as these also provide a supportive and protective aid to sectioning.
