Description

Buffer tablets with a pH of 6.8 are recommended for the preparation of buffer solutions according to WEISE for the staining of blood smears. These tablets are used to make buffer solutions and pH-buffered staining solutions, specifically phosphate buffer solutions, which are commonly used in hematology. They are also used to dilute staining solutions and rinse stained samples during the staining process.

100 buffer tablets are sufficient for preparing 100 liters of buffer solution, and each solution can remain stable for up to four weeks. The buffer tablets according to WEISE are in vitro diagnostic products that are CE registered.

Description

Gram-Color – stain set for the Gram staining method, is used for human-medical cell diagnosis and serves the purpose of the bacteriological investigation of sample material of human origin, for example smears of body fluids. The Gram-Color solutions are modified and designed in such a way that staining can be carried out in staining cells, on the staining rack, and also in automated staining systems. Gram-color modified, phenol-free is a staining set for staining microorganisms. Aniline dyes in the cell tissue of microorganisms form a red dye-iodine complex when exposed to iodine. Sodium hydrogen carbonate enhances the formation of this complex further still. In gram-positive microorganisms the dye-iodine complex cannot be subsequently dissolved from the cells by decolorizing agents such as alcohol or acetone. The cell remains dark blue in color. In gram-negative microorganisms the dye-iodine complex is dissolved and the cell turns red as a result of counterstaining with fuchsin. Gram-color modified, phenol-free is an IVD / CE product.

The package is sufficient for 250 applications. For further information, please see the IFU which can be found in the kit.

Description

Silica gel is a type of stationary phase material used in column chromatography, a separation technique that separates components of a mixture based on their chemical properties. The silica gel 60 offered by Merck has a particle size of 0.040-0.063 mm, which is equivalent to 230-400 mesh according to the ASTM standard. This makes it suitable for use in column chromatography applications where a fine, uniform particle size is required for efficient separation of target compounds. Merck’s Silica Gel 60 is a high-quality product that is widely used in research and industrial laboratories for various chromatography applications.

Silica gel 60 (0.063-0.200 mm) for column chromatography (70-230 mesh ASTM). CAS No. 7631-86-9, EC Number 231-545-4.

Description

For thin-layer chromatography applications, we offer Aluminum TLC plates that are coated with silica gel containing a fluorescent indicator F254. These silica gel TLC plates are available in a set of 50 and measure 5×10 cm. Our classical silica TLC plates are created by combining our established silica gel 60 with a unique polymeric binder. This combination produces a very adherent and robust surface that will not crack or blister and can even withstand writing with a pencil without risking damage to the layer.
