Laboratory & Testing
Indicators and stains are low-volume, high-impact reagents: a titration, a Gram stain or a blood smear fails without the right one. RXSOL stocks the standard list used by water, chemical, clinical and teaching laboratories. pH and complexometric indicators: phenolphthalein, thymolphthalein ACS grade, o-cresolphthalein, bromothymol blue, methyl orange, PAN indicator, alpha-naphtholbenzein, ferroin, potassium chromate, starch–iodide paper. Biological and microbiological stains: methylene blue AR, crystal violet, auramine, Field's Stain A and B, JSB stain, Luxol fast blue, Congo red, indigo carmine, brilliant yellow, metanil yellow, Turk's solution and WBC diluting fluid. Reagent intermediates for synthesis: 1,3-dibromopropane, 1-amino-2-naphthol-4-sulphonic acid and similar.
Pages give the indicator's transition range and colour change, recommended concentration (for example 1% phenolphthalein in ethanol), preparation of the working solution and storage. Small packs (25 g, 100 g, 100 ml, 500 ml) ship by courier from Navi Mumbai.
Colourless below pH 8.2, pink to magenta from 8.2 to 10.0; used for P-alkalinity titrations in boiler water.
Dissolve 1 g methylene blue AR in 100 ml distilled water (or 95% ethanol for some stains); filter before use.
Yes — Field's Stain A (methylene blue/azure) and B (eosin) as ready solutions.
As a redox indicator (0.025 M) in COD and cerium/dichromate titrations; it changes from blue to red-brown at the end-point.
Both; the page states the form and the solvent for the working solution.
