Our original set of dyes and microscopic preparation tools, professionally selected and prepared by our specialist. Probably the most interesting ready-to-use set of this kind on the market. The set includes a comprehensive instruction with instructions for preparing preparations and selection of the proper method of coloring for a specific biological material.

COLORS

Prepared dyes are aqueous solutions with concentrations from 0.1% to 10% - concentrations are prepared depending on the nature of the dye and needs. Distilled water was used for the preparation of the solutions, as well as the corresponding addition of ethyl alcohol, depending on the needs.

The set contains the following dyes (approx. 10 ml each) in brown glass bottles, equipped with a spatula - dropper:

Lugol's liquid - an aqueous solution of iodine in potassium iodide used for staining bacteria by Gram, starch, cell cytoplasm and many other methods

crystal violet - an aqueous solution with the addition of alcohol to stain the bacteria using the Gram method

safranina O - an aqueous solution with the addition of alcohol to stain the bacteria using the Gram method

nigrozyna - 10% aqueous solution - negative staining of experimental microorganisms including bacteria

neutral red - an aqueous solution with the addition of acetic acid - experimental staining of microorganisms, in particular protozoa

Congo red - dyeing yeasts, bacteria as well as survival staining of protozoa. Used also as an indicator of acidity

methylene blue - staining of white blood cells, bacteria, pH indicator. The component of Giemsa dye

Nile blue - lipid staining, as well as an experimental dye in the staining of microorganisms, staining

eosin Y - cytoplasmic staining, red blood cells (component of the Giemsa dye). Widely used in histology and cytology dye, as a contrast dye for hematoxylin

hematoxylin - staining of nucleic acids, a cell nucleus; the basic dye used in histology together with eosin. Includes a dye solution together with alum-potassium alum - Mitchell's hematoxylin

isopropanol - isopropyl alcohol - used interchangeably for decolourising instead of toxic methanol and ethanol


The above uses of dyes are not exhaustive, examples of applications and typical experiments can be found in the accompanying information brochure as well as in specialist and popular literature.

microscope slides - clean basic 50 pieces + 100 covers

specimen needle - preparation needle with a steel knurled handle
