It is easy to clean and sterilise. It allows you see what is going on. Silica is considered Cleaning laboratory glassware is sometimes necessary and may be done using multiple methods. Glass can be used for heating. 2. Glassware can be soaked in a detergent solution to remove grease and loosen most contaminations. Students (upto class 10+2) preparing for All Government Exams, 2. Glass is transparent material and we can see through it clearly. Give the reasons why most laboratory apparatus are made of glass . Glass is transparent material and we can see through it clearly. 4.

Lab apparatus made of glass. Faimus answered the question on December 3, 2017 at 15:15. * Glass is relatively chemically inert so it is neither attacked nor will it contaminate most reagents. Most of the laboratory apparatus is made of glass because: 1. glass is easy to clean. Sturdy glassware may be able to withstand There are many different kinds of laboratory glassware items: It is commonly stopped with a Laboratory glassware can be used for high precision volumetric measurements. It is strong enough to protect us, but it can also shatter frantically into thousands of pieces. The task may require a piece of glassware made with a specific type of glass. Our glass apparatuses are made of borosilicate glass or quartz glass that has good corrosion resistance and high temperature resistance. Borosilicate glass is transparent and can withstand thermal stress. Many parts are available fused to a length of When using glassware it is often necessary to control the flow of fluid. Glass resists heat well. Glass can be easily cleaned. Answers. (Photo Credits : Pxhere) Mysticism of Glass. Glass apparatus is very popular in the laboratories and many chemical industries. Scientific glassblowing involves precisely controlling the shape and dimension of glass, repairing expensive or difficult-to-replace glassware, and fusing together various glass parts. (a) A glass funnel is used to pour off liquids.To prevent the escape of a gas from a gas jar, you will cover its mouth with 1. watch glass 2. crucible 3. beaker 4. round bottom flask Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. These contaminations are then scrubbed with a brush or scouring pad to remove particles which cannot be rinsed. Most importantly does not react with almost all chemicals. It does not react with most of the chemicals used in experiments. 3. Laboratory glassware may be made from several types of glass, each with different capabilities and used for different purposes. The task may be readily performed using low cost, Laboratory glassware may be made from several types of Scientific glass blowing, which is practiced in some larger laboratories, is a specialized field of glassblowing. 5. 5. Although glass has a plethora of applications, it also has a tinge of mysticism around it—likely due to its strange chemical and physical behavior. Laboratory glassware is typically selected by a person in charge of a particular laboratory analysis to match the needs of a given task. Glass does not react with most of the reagents used in the laboratory. Such glasses do not break even at high temperatures.The apparatus to measure an accurate volume of liquid, is 1. beaker 2. conical flask 3. measuring cylinder 4. test tubeThe spirit lamp is made of 1. glass 2. brass 3. steel 4. all of the aboveThe evaporating dish is made of 1. porcelain 2. glass 3. metal 4. plasticWrite true or false against the following statements and correct the false ones. Examples of glassware used for measurements include: Next: What is chemistry?

With high precision measurements, such as those made in a testing laboratory, the Laboratory glassware is composed of silica. Because glass is not expensive, transparent, not porous, doesn't react with many chemicals, it is easily manufactured and formed in very special installations, easily joined with metals, etc. * It is transparent so you can see colour changes etc which is often very important in experimental chemistry. Glass Condenser, Glass Water Separator Has Anti-Corrosion, Sealing Tightly. 3. Quartz glass can withstand very high temperatures and is transparent in certain parts of the electromagnetic spectrum.Darkened brown or amber (actinic) glass can block ultraviolet and infrared radiation. Glass withstands high temperatures. It does not react with most of the chemicals used in experiments. Pyrex glass or borosil glass is a special type of glass which hardly expands on heating.
