- A very common use for diatoms is for filtration. The fine structures of diatom shells trap foreign particles in fluids, such as dirt, lint, hair and some other microscopic organisms. Diatoms are often used to filter water, particularly water in hot tubs and swimming pools.However, a vast variety of fluids can be filtered with diatoms, including different syrups, alcoholic beverages, medicines, solvents and other chemicals.iatoms are often used to filter water, particularly water in hot tubs and swimming pools.

Pasteur pipette For other uses, see Dropper (disambiguation). Pasteur pipettes, also known as droppers or eye droppers, are used to transfer small quantities of liquids. They are usually glass tubes tapered to a narrow point, and fitted with a rubber bulb at the top. The combination of the Pasteur pipette and rubber bulb has also been referred to as a teat pipette.

Lab Manual for SFGH The preferred pediatric collection container for chemistry testing is the amber SST bullet (500 µL). When collecting blood specimens (venous, capillary, arterial) for chemistry testing from newborns (hematocrit greater than 50%), we recommend the use of a green top bullet with heparin (400 µL).

Apothecary Jars and Bottles Apothecary shelf bottles usually had ground glass stoppers. Both the stopper and the inside of the jar’s mouth would be sanded to form a tight seal. They served their obvious practical purpose of keeping materials inside the jars, but like the jars themselves, they were also often ornate and decorative. Apothecary glassware would have adorned the inside of an old-time pharmacy.

Particle Theory The simple particle model is less helpful in explaining why there is a limit to the solubility of any material or why the solubility varies at different temperature. Although we most commonly think of dissolving solids in water other liquids can act as solvents. Nail varnish remover is used to dissolve nail varnish and, white spirit to dissolve some kinds of paint and petrol is a good solvent for grease. Many non water solvents are not really suitable for use with primary children.

Strontium hydroxide From here, the solution is filtered, and the Sr(OH) 2 is washed with cold water and dried. Applications. Strontium hydroxide is used chiefly in the refining of beet sugar and as a stabilizer in plastic. It may be used as a source of strontium ions when the chlorine from strontium chloride is undesirable.

Gas syringe Gas syringe. A gas syringe is a piece of laboratory glassware used to insert or withdraw a volume of a gas from a closed system, or to measure the volume of gas evolved from a chemical reaction. A gas syringe can also be used to measure and dispense liquids, especially where these liquids need to be kept free from air.

hopper hopper A hopper is a funnel-shaped device used to move material from one receptacle to another. This type of hopper has nothing to do with hopping or jumping: it's a device — the kind you're most likely to see in a chemistry lab — for moving substances from one container to another. If you need to pour a large beaker of liquid into a tiny test tube, the hopper lets you move the liquid without spilling.

Chemistry Chemistry. The primary function of the Chemistry Section is to analyze items of evidence in order to determine the presence or absence of controlled substances.hemists provide expert testimony to the courts, supply the courts and other state agencies with factual drug information, and provide information to the general public and news media about drug abuse. Additionaly, a team of scientists is trained to assist police officers in clandestine laboratory seizures.

Toxic Substances Portal - Tetrachloroethylene (PERC) Tetrachloroethylene is used as a dry cleaning agent and metal degreasing solvent. It is also used as a starting material (building block) for making other chemicals and is used in some consumer products. When you bring clothes from the dry cleaners, they will release small amounts of tetrachloroethylene into the air. 2  When you drink water containing tetrachloroethylene, you are exposed to it. 3  You might also be exposed to tetrachloroethylene that is released into the air during showering and bathing.

Alum for Pickling 1 Shaving alum is a powdered form of alum used as an astringent to prevent bleeding from small shaving cuts. 2  The styptic pencils sold for this purpose contain aluminium sulfate or potassium aluminium sulfate.3  Similar products are also used on animals to prevent bleeding after nail-clipping.f good quality produce and modern canning methods are employed, there is no need to use alum to bolster the crispness of the pickles and cherries. In any event, even if alum is used to soak the pickles, it should not be used in the final pickling liquid.
