Basic School Science and Lab Equipment
It is generally desirable to own a maximum of two or three students using each pair of equipment. There also needs to be adequate clean beakers, etc., so the period is not wasted in the small amount of time allotted to the experiment by having to re-wash and clean equipment.
While there could be certain components of equipment unique to a number of the experiments that the students will cover in the year, there are several basic items that you will find in virtually every school science laboratory.
Every laboratory should be near to emergency washing and even showering facilities. Furthermore, the lab should be equipped by having an eyewash station.
Then you will find the safety procedures that the teacher should be knowledgeable about, in addition to all safety equipment that might be required for himself and for every single student. These generally include safety glasses, appropriate gloves when required for some experiments, lab coats to safeguard clothing and fire extinguishing equipment for all types of fires likely to occur.
The glassware that's normally part of a laboratory includes:
* Test tubes and graduated cylinders.
* Beakers, graduated in 50ml to 400ml capacities.
* Flasks of varying types, such as for example Florence flasks with rounded bottoms for heating substances, graduated Erlenmeyer flasks, Filter flasks with and without vacuum connections and/or taps. Volumetric flasks have an exact graduation mark for a particular quantity of whatever substance has been measured.
* Pipettes; these come in single graduation for delivering one exact volume, called a Volumetric pipette. You then get graduated pipettes which can take different volumes of liquid, called a Mohr pipette.
* To opt for the pipettes you obtain pipette bulbs or pipette fillers for sucking liquids to the pipettes.
* There are evaporating dishes and watch glasses that the same things, in much smaller quantities.
* Funnels and filter funnels.
* Stirring rods and chemical spoons.
In addition to the various components laboratory refurbishment of graduated glassware, other measurements have to be taken as well. Electronic scales and balances are used to discover mass. There are several electronic instruments available for measuring dimensions, pH and moisture, among those ideas that could be highly relevant to the students experiments.
Bunsen burners are used in virtually every school laboratory, and all the paraphernalia that goes with them, such as for example hoses, ring stands, many different clamps and supports, and wire gauze.
Other equipment includes crucibles with tongs, many different racks for test tubes and flasks, pestles and mortars, and stoppers of all types with and without holes for glass tubing.
