1. Fill a water sample of approx. ...
2. Fill a 10 ml water sample into another cuvette.
3. Add 1 Hard check tablet, crush it and after having closed the cuvette mix until everything is dissolved.
4. Wait 5 minutes until the reaction time is over.
5. Switch the Spectro 3 Photometer on with any of the keys.

The total hardness test can be used to measure water hardness. Water hardness is caused by the presence of alkaline earths, primarily calcium and magnesium.

Crystals or granules are dark purple with a metallic sheen, sometimes with a dark bronze-like appearance. Free-Flowing Grade is gray due to an additive. Potassium permanganate has a sweetish, astringent taste and is odorless.

It is used as a dehydrating agent for natural gas processing; as a lubricating and finishing agent for textiles; a constituent in brake fluids, lubricants, antifreeze formulations, wallpaper strippers and in artificial fog solutions; a solvent for printing inks and textile dyes; and is used as an intermediate in the 

Potassium permanganate (KMnO4) is a strong oxidizing agent . As an oxidizing agent it has the ability to add oxygen, remove hydrogen or remove electrons from an element or compound. Potassium permanganate is made up of 1 manganese atom surrounded by 4 oxygen atoms. The molecular weight of permanganate is 158.04 g/mol.

TREHALOSE FOR BIOCHEMISTRY  used in Japan to prolong food shelf life, trehalose protects foods from drying out, starch-containing products from going stale, and fruits and vegetables from discolouring

 now  widely used in Japan to prolong food shelf life, trehalose protects foods from drying out, starch-containing products from going stale, and fruits and vegetables from discolouring. It also suppresses ice crystal growth in frozen foods, reducing food loss.

Uranyl acetate is extensively used as a negative stain in electron microscopy. Most procedures in electron microscopy for biology require the use of uranyl acetate.

Uranyl acetate produces negative stain contrast in TEM micrographs due to its exclusion from the dense ordered peptide structures, providing dark highlights along the fiber edges.

Trypan blue is commonly used in microscopy (for cell counting) and in laboratory mice for assessment of tissue viability. The method cannot distinguish between necrotic and apoptotic cells. It may be used to observe fungal hyphae and stramenopiles.

Appearance: deep blue in aqueous solution.

Trypan Blue has a greater affinity for serum

proteins than for cellular protein. If the background is

too dark, cells should be pelleted and resuspended in
