VWR offers a broad line of reagent droppers, diagnostic kits, and antigens and antisera, for aid in identifying a variety of microscopic organisms. The visualization of bacteria by means of staining procedures is an important tool for any microbiologist to have at their disposal, and these carefully standardized and reproducible stain reagents help to ensure accurate and easily interpretable results. Stains are also available to provide early detection of positive blood cultures by fluorescence procedures.

Zinc Formalin Fixative
Supplier: SIGMA ALDRICH MICROSCOPY
Zinc formalin fixative is a non-precipitating fixative. This fixative is compatible with histochemical, immunochemical and special stains. It may be used with automated tissue processors and also in manual methods. The zinc chloride component of the formulation increases the rigidity of cellular components to withstand subsequent processing, sectioning and staining procedures. Tissue specimens initially fixed using 10% neutral buffered formalin solution may be post-fixed using the zinc formalin fixative.

Immersion oil viscosity 150 cSt (lit.), Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
Immersion Oil has a defined refractive index of about 1,516. It is important that the refractive index (nD) is about 1,5, similar to that of glass. This enables a homogeneous oil immersion to be achieved.

Embedding medium, PolyFreeze, Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
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.

Mounting Medium, CC/Mount™
Supplier: SIGMA ALDRICH MICROSCOPY
CC/mount is an aqueous based permanent mounting medium with a very high refractive index, which when applied to the stained tissue sections can store the tissue specimens permanently without the fading of the chromogens. Because of the superior refractive index of CC/mount, tissues mounted in this medium look like specimens mounted with organic based mounting media. No coverslipping is required with CC/mount. However, if coverslipping is required, dried CC/mount can be post mounted by using an organic based mounting medium. CC/mount permits the long-term storage of antigens localised using organic insoluble chromogen substrates, including AEC, DAB, Fast Red, BCIP/NBT, BCIP/INT and fluorescent dyes like FITC and phycobiliproteins. The high pH of CC/mount ensures increased stability of fluorescence intensity.

Mounting medium, Entellan® new
Supplier: Merck
Entellan® new is a new mounting medium for cover slippers and is specially suited for commercial automated mounting instruments that operate with cover slippers. Its viscosity ranges between 250 and 600 mPas, 1,00869 has a small viscosity range. This narrow viscosity range improves and accelerates the application, as neither the dropping rate nor the volume need to be reset after the first run with a new bottle of Entellan® new.

Water-free mounting medium, Neo-Mount®
Supplier: Merck
Water-free mounting media, such as Neo-Mount®, should be used for permanent mounting and long-term storage of samples. Slides processed in pathologyl laboratories need to be stored up to 10 years, whereby the staining results need to be stable and fading-out is not acceptable. Neo-Mount®, anhydrous mounting medium for microscopy is an extremely colour-stable mounting medium for microscopy, which is produced with solvents based on mixtures of aliphatic hydrocarbons. It contains an aromatic-free substitute for xylene, thus, Neo-Mount® needs to be combined with Neo-Clear® exclusively. Xylene must be avoided in the mounting step, as it will cause the slides to become cloudy and streaked. In addition, by placing the dehydrated slides on filter paper for approx. 1 minute prior to mounting, any excess Neo-Clear® should be circumvented, as air bubbles might arise under the cover slip. The same pre-condition should also be met when mounting specimens using cover slip machines; in this area, Neo-Clear® can be most efficiently eliminated by incubating the slides for 1 minute in an empty slide rack.
