Lab Instruments And Chemicals
Generally speaking, due to homework, we can find various laboratory equipment and devices, but many times it is difficult to distinguish between suitable laboratory chemical equipment, laboratory biological equipment and other similar means. The basic concepts of suitable and necessary chemical laboratory equipment should be clarified Students start from the day they conduct basic chemistry experiments in the school laboratory.
The need to be familiar with various equipment means that students have solid basic knowledge and skills Schools and universities should pay special attention to making students aware of this.
Let's take a look and try to understand the basic equipment used in the school's chemistry laboratory and its specific use in any chemistry experiment.
The first equipment that any student or participant entering a chemistry laboratory should know is a safety device.
In these areas, security protocols must be strictly followed, because a small mistake or misfortune can lead to serious losses and serious consequences.
Closed shoes should always be worn in the laboratory, ...
... not sandals or slippers.
Safety glasses:
Safety glasses should be worn in chemical laboratories. Protect your eyes from the irritation of chemicals or fumes released during the experiment. If chemicals or acids are accidentally spilled, it can also protect us from blindness.
Glasses:
The glasses are cylindrical bowls made of borosilicate glass with a flat bottom and an upper opening with a rim and spout. The spout on the edge helps to pour out the solution correctly, and there is no lid on the top. In most cases, the table mirror is used to cover the solution. They are available in a variety of sizes to accommodate, heat or mix the right amount of material. Although they come with hierarchical calibration, they are not designed to accurately calculate solutions, so other devices are also useful.
Cooking bottle:
The cooking bottle is also called the Florence bottle, with a round bottom and a long neck. It can be closed with a rubber or glass stopper and is mainly used to store solutions, and can be easily heated by the corresponding rotating motion for proper mixing.
Watch glass:
The device consists of a concave glass. It is often used to hold solids, evaporate liquids, and heat a small amount of various substances according to the needs of the experiment. Sometimes, they can also be used as a lid for a cup.
Pipette.
Pipettes come in different sizes and are designed to reach a certain volume. These are narrow cylindrical glass tubes that allow you to accurately measure the volume of liquid and pour it into another container.
Ring stand, ring and clamp:
These are devices used to hang burettes, flasks, crucibles, etc. Heat through other containers or through Bunsen burner. When heating these lamps, the metal grille is a necessary device to evenly distribute the heat.
Watch glass:
The device consists of a concave glass.
Crucible-
The crucible is made of porcelain and is used to store and heat the fabric as needed. Heat to high temperature, because glassware is not always suitable for such high temperature experiments.
Funnel:
Funnel is an indispensable device for filling materials and solutions into narrow neck tubes and conical flasks. There are many options, the most common of which are filters, thistles and drip funnels.
Volumetric Flasks:-
Volumetric flask is one of the most important laboratory glassware in any laboratory instruments the glass is calibrated to withstand precise volumes of liquid at any precise temperature. Volumetric flasks are available in a variety of sizes, each of which is calibrated to accurately measure liquids and solutions.
Lab Apron:
Lab apron has a similar role as the safety goggles, but here the difference just being that It is not only used to protect the eyes, but also to prevent injuries caused by spills or splashes. So as not to be injured by spilling or splashing.
Mainly used to prepare standard solutions.
Oxidationsmittel:
anorganische Nitrate, Nitrite, Permanganate, Chlorate, Perchlorate, Jodate, Periodate, Persulfate, Chromate, Hypochlorite, Peroxide, Peroxide Borate.(ex: Potassium Perchlorate, Calcium hypochlorite, Sodium nitrate, Sodium iodate, Ammonium persulfate, Sodium peroxide)
Acidic Flammable Liquids:
Glacial acetic acid (100%), acetic acid (>80%), acetic anhydride, formic acid (and >85%), propionic acid (100%) (Also called propionic acid)Mixtures of acids and flammable liquids Cyanides Sodium cyanide, Potassium cyanide, Calcium cyanide
Pyrophorics (air-reactive):
Metal alkyl and arylene methyl lithium, trimethyl aluminum, diethyl zinc, phenyl lithium. On-metal alkyl, such as triethylborane, trimethylphosphine, phosphorus (white)
