Some Chemistry in the Laboratory Equipment and its Functions

NAME OF TOOLS	FUNCTION
Rotavapor	To separate a mixture of substances. For example, to separate the solvent n-hexane is used for oil megektraksi of materials.
Spray bottle	typically used for distilled water of saving and used to wash or rinse the materials are not soluble in water. In addition it is also used to wash or neutralize the equipment to be used. How to use: press the bottle then distilled water will come out.
Petri dish or cloud Eko or telepa Petri (there are 2 kinds of glass and plastic)	used for culturing the cells. Petri dishes are always in pairs, whose size is rather small as the larger container and a lid
pH meter (there are 2 kinds of digital and anolog)	Various pH meter that has been produced by the factories. Used to measure the acidity of a substance. Usually before use dikalibarasi first using a buffer solution. Buffer solution has usually been included in the packaging, can also be purchased in stores chemicals.
Multimeter (there are 2 kinds of digital and analog)	To measure the electric current strength or resistance. For example, to measure the strong currents generated by redox reactions in the galvanic cell.
ozone generator	To create ozone in the laboratory with the basic ingredients of oxygen (O2) pure
Fire Tube API Powder / Multipurs	fire brigade
Büchner funnel connected to a flask connected to a vacuum pump.	Used to filter. Filter material (usually paper filter) is placed on top of the funnel and wetted with solvent to prevent leakage at the start of screening. The liquid to be filtered poured into the funnel and sucked into the flask from a porous base funnel with vacuum pump.
bomb calorimeter	Bomb calorimeter is a device used to measure the amount of heat (calorific value) are released on combustion (in excess O2) a compound, groceries, fuel. A number of samples were placed in tubes submerged in oxygenated medium heat absorber (calorimeter), and samples will be burned by the fire power of erpasang metal wire inside the tube.
solution calorimeter	Solution calorimeter is a device used to measure the amount of heat involved in chemical reactions in the system of systems. Basically, the heat released / absorbed causing temperature changes in the calorimeter.
Scales or balance	To weigh the mass of a substance
analytical balance	To weigh the mass of a substance. Higher level of accuracy in the balance sheet.
Evaporating dish atau cawan porselin	Used as a container to react or change a substance at high temperatures. For example, evaporation of solvent from a material that does not easily evaporate, cremate filter paper.
Nichrome wire (alloy of nickel and chromium) (flame color elements sodium, lithium and copper, potassium, calcium, antimony)	To identify a substance by way of flame test. This is due to any substance that gives color to flame specific meaning each agent has a different color from one another. However some substances give almost the same color of the flame so it is difficult to distinguish. Besides nichrome wire, a platinum wire is also Often used.
	Container or a place to store chemicals
Bottles reagent or reagent bottles	Used to store chemical solutions or often also used to store the acid-base indicator such as phenolphthalein.
Lup	Magnifying glass. Can be used to observe an increase or decrease in temperature on the thermometer mercury thermometer mainly colorless.
