ASSIGNMENT APPARATUS IN LAB

          Science is a field of knowledge that includes organized studies of physical and natural phenomena. Chemical science involves studying the behavior of matter  around us through observation and experimentation. The  curriculum of chemical science schools in most countries consists of two parts: theory and practice. Theory literally conveys knowledge to students, while practice connects theory with physical reality. Experiments are an important part of  chemical science as they help us better understand the complex interactions of chemicals. Common facilities that provide a controlled environment for conducting these experiments are known by the name of the institute of a school, institution, or  other organization. When working in a chemistry laboratory, you will come across a variety of equipment needed to carry out experiments. It is important to understand how these devices work. If it doesn't work, not only does it increase the risk of experimental error, but it also creates potential laboratory risk. The following is a list of commonly used chemical experimental equipment and its applications.

From all of the apparatus above, we will choose three to make in 3D using Autocad or Solidwork.

1. TEST TUBE

           In a chemistry lab, the test tube is one of the most widely used glassware apparatus. It is a cylindrical vessel with a round bottom that is used to hold chemicals during the experiments. Due to their high thermal stability, test tubes can be used to heat or boil chemical samples. While heating, it’s essential to hold the test tube at a 45-degree angle so that the gases formed inside the narrow tube may easily escape without causing the hot liquid to shoot up.

The real size of the test tube, the height is 150 mm and diameter is 18 mm.

2. BEAKER

Beakers are the most widely used laboratory apparatus. They are usually made out of glass, plastic, or heat-resistant glass and are generally cylindrical in shape with a flat bottom.

 It is a container with many functions and often times it is used for stirring, mixing and heating processes for experimental or procedural purposes. 

They come in different sizes like 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, and even 1000ml. Each beaker typically has readings on the surface to indicate volume levels in the container. The beaker shown is a 250mL sized beaker done in Solidwork.

3. Droppers

The dropper is a  simple small lab instrument, generally comprised of a plastic or glass cylinder, with a small nose on one side and an elastic holder on the other. It is utilized to hold reagent or solutions and utilized dropwise during any chemical analysis.

The capability of a medication dropper is to dispense liquid medication. Droppers have graduated mark on them to decide the appropriate measurements. A dropper is utilized to drop a little sum on your device. A dropper is utilized to apportion modest quantities of a fluid.

Volume of fluid in a CBD dropper For this standard size, the dropper normally has 1 ml of all out fluid. This expects a full dropper.
