In most labs, you'll encounter the same basic apparatus. Here, you will find a picture and an explanation for how to use each piece of equipment. You will learn about: 1. Safety goggles and safety equipment 2. Beakers 3. Erlenmeyer flasks, AKA conical flasks 4. Florence flasks, AKA boiling flasks 5. Test tubes, tongs, and racks 6. Watch glasses 7. ...
The first and foremost rule of any laboratory is to be safe! This may seem obvious, but people often disregard safety protocols for one reason or another, putting themselves and those around them in danger. The best thing you can do is to make sure you follow all safety protocols at all times.
Safety goggles are required wear in all chemistry labs. Not wearing them puts you in danger of eye irritation and possibly blindness in the case of an accident. A small droplet of acid could splash out of the container at any time. Better safe than permanently blinded! Latex gloves should be used when there is a possibility of corrosive chemicals s...
A beaker is a common container in most labs. It is used for mixing, stirring, and heating chemicals. Most beakers have spouts on their rims to aid in pouring. They also commonly have lips around their rims and markings to measure the volume they contain, although they are not a precise way to measure liquids. Beakers come in a wide range of sizes. ...
Also known as a conical flask, the Erlenmeyer flask was named after its inventor in 1861. It has a narrow neck and expands toward its base. This allows easy mixing and swirling of the flask without too much risk of spilling. The narrow opening also allows for the use of a rubber or glass stopper. It can easily be clamped to a ring stand (discussed ...
Also known as a boiling flask, the Florence flask has a round bottom and a long neck. It is used to hold liquids and can be easily swirled and heated. It can also easily be capped by rubber or glass stoppers. Once again, safety dictates that this flask never be heated when capped. Pressure build-up and explosions can and do occur.
A test tube is a glass tube with one end open and the other end closed. The closed end is rounded. Test tubes are used to hold small samples. They are primarily used for qualitative assessment and comparison. A common place to see these is the biochemistry lab. When a large number of samples need to be tested and compared, test tubes are used to ma...
A watch glass is just a round piece of glass that is slightly concave/convex (think of a lens). It can hold a small amount of liquid or solid. They can be used for evaporation purposes and also can function as a lid for a beaker.
A crucible is a small clay cup made of a material that can withstand extreme temperatures. They are used for heating substances and come with lids.
A lab funnel is just like any other funnel except that it was designed to be used in a laboratory setting. They can be made of plastic or glass and can have either a short stem or a long stem, depending on what they are needed for. There are several sizes that can be chosen from based on the amount of liquid that needs to go through them quickly.
- Bunsen burner. A Bunsen burner is a source of heat or mechanical appliances for which absolute safety is required while using Bunsen Burner. it is linked to a flammable gas source.
- Tripod stand. It is usually made of stainless steel or Aluminium having three supporting legs. The apparatus to be heated is placed on the tripod stand. It is mainly used to support or hold the beakers or flasks during the experiments.
- Wire Gauze. It is the iron wire gauze piece posted with asbestos in the center. It is placed on the tripod stand so that the flame does not touch the glass apparatus directly, reducing the danger of its breaking.
- Test Tubes. You have to wait 30 seconds. Generating Next Article link. A test tube is a glass tube with one end closed and the other end open. The closed-end is in a round shape.
- Bunsen Burner. A Bunsen burner is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilizing, and combustion.
- Erlenmeyer Flask. An Erlenmeyer flask is a conical shaped container with a flat bottom and a cylindrical neck. The narrow neck of the flask helps to prevent the escape of fumes and vapors, while the wide base helps in stability.
- Graduated Cylinder. A graduated cylinder is a common piece of laboratory glassware used to measure the volume of liquids. It has a cylindrical shape with a narrow neck, and it comes in different sizes, from small to large.
- Beaker. A beaker is a common piece of laboratory equipment used to hold and mix chemicals. It has a cylindrical shape with a flat bottom and a lip around the rim to aid in pouring.
Introduction. This resource shows the standard pieces of equipment found in most university and research chemistry laboratories. Contents. A-C: Addition funnels, balances, chromatography columns, condensers. D-F: Dean-Stark apparatus, desiccators, distillation recievers, filtration. F-M: Flasks, fractionating columns, lab jacks, manometers.
It is essential to understand the functioning of these apparatus, as an ineffectiveness not only increases the risk of experimental error but also poses a potential laboratory hazard. The following is a list of commonly used chemistry lab apparatus, along with their uses.
Laboratory apparatus are essential tools that enable scientists to conduct experiments. By using lab tools, they can make measurements, and gather data in a controlled environment. These instruments range from basic items like beakers and test tubes for mixing and storing liquids.
