Laboratory apparatus drawing and their uses pdf Continue Many types of devices are used for scientific work in laboratories. however, we have compiled all possible general and comprehensive lists of 20 laboratory machines and their use. they allow us to successfully conduct experiments and make accurate measurements or observations. all common laboratory machines should be structured in general terms only and in their correct proportions. 50 common Laboratory machine is this: Bunsen burner Tripod Tripod Stand Wire Gauze Bath Tube Test Tube Test Tube Booth Beakers Conical or Titratling Flask Funnel Glass Funnel Rubber Cork Reagent Bottle Washing Bottle Aspirator Glass Tube Ring Clip Porcelain Dish (Evaporating Dish) Crucible Tongs Capacitor Crucible with Cap Measuring cylinders mortar and pestle Forceps Flat bottom flask Paper Measuring Flag No Weights Desiccator Spatula Stirring Rod Separation Funnel pH meter Burette Burette clip Buchner funnel Pipette Test Tube Rack Tube Brush Thermometer Watch Glass Iron Stand Iron Iron Clip Ring Rubber Tube Litmus Paper Clay Triangles Pipet Bulb Now! Below are some elements of a common laboratory used in the lab. The name and function of the device used in the lab: The Bunsen A Bunsen burner is a source of heat or mechanical devices that require absolute safety when using Bunsen Burner. it is associated with the source of flammable gas. The main stick is used to adjust the amount of gas flow and the web collar that drives the airflow. Both the handle and the collar need to be adjusted to get a great flame to heat things up. Tripod Stand It is usually stainless steel or aluminum having three auxiliary legs. The heating device is placed on the stand tripod. It is mainly used to support or hold glasses or flasks during experiments. The Bunsen burner is placed under the tripod stand because of its height. Wire Gauze Is a piece of gauli iron wire placed with asbestos in the center. It is placed on a tripod stand so that the flame does not touch the glass apparatus directly, reducing the risk of its destruction. The test tube is a glass tube with one end closed and the other end open. The closed end is in a round shape. Test tubes are used in laboratories to hit small samples. They are mainly used for qualitative comparison and evaluation. It is very common to see test tubes of biochemistry laboratory. When a large number of samples need to be compared and tested, these test tubes are used to make it easier. They are also easily covered or limited by glass or rubber cork. Safety Tip: Never heat a covered or limited test tube. Glasses are a very common laboratory tool and are widely useful in the laboratory as a reaction container.they are also used to conduct liquid and solid samples or catch fluids from a variety of different or filters from filtering operations. The glass is a simple can in most laboratories. Used for heating, mixing and mixing chemicals. Most glasses have spouts on the wallpaper to easily fill. Use glasses in the lab They also usually have lips around their rim and markings to measure the amount of fluid they contain. They are not part of proper fluid measurement equipment. Glasses are available in a wide range depending on their size, such as 50cm3, 100cm3, 250cm3, or 500cm3 available. Beaker Tongs Titration flasks It is also known as the Conical Flask. Erlenmeyer's flask was named in 1861, after its inventor. It has a thin neck and expands to its base. This allows for easy swirling and mixing flasks without too much possibility of spilling. The narrow hole also allows the use of a glass or rubber cork. It can be conveniently clamped to the ring bench as well as shaken or heated easily. Once again, the rooms on the side are designed mainly for evaluation not for accuracy. Safety Tip: A significant safety tip here is to never heat the flask until it is covered. This leads to an increase in pressure, which leads to an explosion. The funnels are a laboratory funnel just like any other funnel, but it has been specifically designed for use in the lab. They are made of glass or plastic and have either a long stem or a short stem, depending on the purpose they are needed for. There are many sizes that can be selected depending on the amount of fluid that needs to go through them easily and quickly. Funnels of different sizes 3cm, 5cm, 8cm, etc. Evaporation Dish (China Dish) This small dish of porcelain is used for evaporation and concentration of diluted solutions. It is available in different sizes. Graded or measuring cylinders are a necessary measuring tool for the volume of any liquid. There are many markings up and down the entire length of the container with special steps. The scaled cylinders have many sizes. The smaller they are in size or diameter, the more accurate or accurate the volume measurements will be. When considering the volume of graded cylinders, you will assume that the liquid seems to have some indentation. At the edges of the graded cylinders, the liquid will be higher than the liquid in the center. It's known as meniscus. Keep the cylinder on the leveled surface to read the volume correctly. They are also available in various sizes 5cm3, 10cm3, 20cm3, 50cm3, 100cm3 and 1000cm3. The Rod Stirring Rod mixing or glass stirring rod is used to mix and mix various chemicals. It consists of solid glass (borosilicate or) with rounded edges a little thick and longer than a straw of soda water. Stirring rods often 10 to 45 cm long with almost half a centimeter in diameter. It is also available in a triangular paddle, flat paddle, or round button shape. Measurements OR Tomtric flasks Volume Flask is a round flask with a flat bottom and a long neck. The tomtric flask is used to measure the exact volume of liquids. There is a short line around the neck that hints at how far to fill the flask. Special caps are available that won't let anything in or through the flask. They are available in a variety of sizes, i.e. 100cm3, 250cm3, 500cm3 and 1000 cm3. Just remember: the temperature affects the volume; so always avoid using liquids that will change in temperature (e.g. hot water that will cool). Buret Burets are often used to add accurate and accurate volume of liquids. With the help of drills you can measure or determine the volume of liquids to almost 0.01 ml. They are usually attached to the ring stand with a clamp. The drill is also similar to a glass tube, which is opened from above and becomes a narrow sharpened hole at the bottom. Right above the bottom hole; There's a stop. This stop can be turned on to control the amount of fluid released. There are also certain markings along the length of the storm that indicates the volume of any liquid present in them. The drill is especially used for extremely accurate addition of liquids. Slightly adjusting the stop, the amount of liquid released can slow down to one drop every few seconds. Buret is one of the most accurate tools in the lab. To determine the added amount of liquid in the solution, write down the readings of how much is initially present in the drill. Then, when you're done adding liquids, write down how much liquid is left. Now subtract the final amount of liquid from the original amount and you have the exact amount of liquid that is added. Forceps Forcep comes from the Latin word forcipes used to capture and capture small objects in laboratories. They are used when things are picked up in bulk or when thumbs are unable to collect small and tiny things. in addition, force is a very common word in the medical field. In the general world, the forces are called different names like pliers, tweezers, clip, stongs, or clips, etc. basically there are two main types of types: Nondegradable Force and Disposable Pipettes types like a laboratory apparatus There is a great variety of pipettes that are designed to achieve many specific goals. However, they all measure the exact volume of liquids and then place the liquids in other containers. Generally available sizes are 10cm3, 20cm3 and 25cm3. The temperature of the substance is measured by a thermometer. The temperature in the lab is usually measured in units of the Degree Celsius ( . often used for a time a small amount of solid or liquid to make fluid, while weighed and many other targets. Watch glasses are also used for a variety of purposes such as evaporation. It can also work as a cover for the glass to prevent dust from entering the glass. The chemical laboratory uses two types of watch glasses, such as glass glasses and plastic glasses. Both types have different sizes and varieties on the market. The type of glass is better known than the plastic type. basically the type of glass is reused, and the plastic types are disposable, i.e. for disposable use. Pipet Bulb Pipet Bulb is used to wring various liquids into the pipe. Iron stand It is used for hanging (thermometer), clamp/holding (burett, round lower flask, etc.). The ring clip clip is used with a ring stand to hold different types of glassware like a funnel or glass. Washing bottle Currently plastic bottles are used in the laboratory to store distilled water for various operations, such as transporting sediment from the container to the filter paper or washing the precipitation.
