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.

Two-sided slide with agar-agar centre. Operating instructions: 1. Unscrew the cap containing the agar-agar slide. Hold the bottle in the other hand and lightly apply pressure to the sampling area using the agar-agar slide; or 2. Apply directly to the middle of the swab brush if you have completed a swab sample; or 3. Immerse the agar-agar slide in the liquid to analyse. 4. Insert the slide into the bottle and screw back on. Place in the oven at 37 °C for 24/48 hours. To detect yeasts, increase the incubation by 24/48 hours at 25/30 °C.

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.

Differentiation solution comprises acidified ethanol or isopropanol that is used to decolourise hematoxylin stain. The duration of exposure to the solution determines the degree of decolourisation. Differentiation is a crucial step in hematoxylin-eosin staining to achieve the proper colour contrast necessary for visualisation, by selectively removing excess hematoxylin from the tissue section and leaving behind the desired staining intensity.

Micro Extraction by Packed Sorbent (MEPS™) is a new development in the field of sample preparation by SPE (solid phase extraction). The MEPS™ product consists of two parts, the MEPS™ syringe and the MEPS™ Barrel Insert and Needle assembly (BIN). The MEPS™ approach to sample preparation is suitable for reversed phases, normal phases, mixed mode and ion exchange chemistries. Because MEPS™ BINs can be used for sample volumes as small as 10 µl it makes them particularly well suited to on-line use with LC-MS analysis of volume limited samples.

The Epoxy Embedding Medium Kit is a very widely used embedding medium for electron microscopy. The embedding formulation originally published by Luft (1961) is excellent for both plant and animal tissues. Due to the low viscosity of the resin, it penetrates the tissue specimen faster than Araldite and other polymers. It hardens easily and uniformly at low temperatures with the addition of dodecenylsuccinic anhydride (DDSA), methyl nadic anhydride (MNA), and the accelerator 2,4,6-tris(dimethylaminomethyl)phenol (DMP-30). Slight shrinkage may occur during curing. This kit is useful for embedding a variety of tissues as a wide range of hardness can be obtained with this resin to suit a specific tissue type by using two different anhydride curing agents (DDSA and MNA).
