What type of glassware is used in laboratories?
Borosilicate Glasses This is among the most common type of glass found in laboratories and is used in beakers, vials, test tubes, flasks etc. This material has a low expansion that makes it suitable for a wide variety of laboratory applications.
What are the three type of laboratory glassware?
Types of Laboratory Glassware
- Beakers – One of the most common types of laboratory glassware, beakers are basic containers used to hold samples and reagents.
- Desiccators – Absorb moisture from a substance.
- Graduated Cylinders – Very similar to a beaker but with volume measurements.
What is the meaning of laboratory glassware?
Laboratory glassware refers to a variety of equipment used in scientific work, and traditionally made of glass. Glass can be blown, bent, cut, molded, and formed into many sizes and shapes, and is therefore common in chemistry, biology, and analytical laboratories.
Why is borosilicate glass used for laboratory glassware?
Virtually all modern laboratory glassware is made of borosilicate glass. It is widely used in this application due to its chemical and thermal resistance and good optical clarity, but the glass can react with sodium hydride upon heating to produce sodium borohydride, a common laboratory reducing agent.
What are lab tubes called?
A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom.
What are the names of beakers?
The Names of Chemistry Flasks
- Flask and Beaker Chemistry. Most flasks and beakers are made of glass, but specialized uses sometimes suggest using other materials.
- Types of Beakers.
- Erlenmeyer Flasks.
- Round Bottom Flasks.
- Volumetric Flasks.
- Filtering Flasks.
- Distillation Flasks.
What is the function of glassware?
Glassware used as laboratory apparatus offers a wide range of containment and transport functions for solutions and other liquids used in laboratories.
How can you tell if glass is borosilicate?
How to identify if an unknown glass is borosilicate glass, without leaving the Lab!
- Boroslicate glass can be readily identified by its’ refractive index, 1.474.
- By immersing the glass in a container of a liquid of similar refractive index, the glass will disappear.
- Such liquids are: Mineral oil,
What are test tubes called?
What are the two main types of glassware?
There are four main types or strengths of glass:
- Annealed Glass. Annealed glass is a basic product formed from the annealing stage of the float process.
- Heat Strengthened Glass. Heat Strengthened Glass is semi tempered or semi toughened glass.
- Tempered or Toughened Glass.
- Laminated Glass.
How many ml is a pipette?
These disposable pipets are also called pipettes and work similar to an eye dropper or medicine dropper. Use them for quick, safe transfer of liquids. Each is 6 inches long and the tip is graduated to 1 ml and marked at . 5 ml.
Why did Pyrex stop using borosilicate?
But in 1998, Corning, the company which made Pyrex, sold the brand to World Kitchen LLC. World Kitchen decided to stop the manufacture of borosilicate glass, and since then, Pyrex sold in the United States is made of tempered soda-lime glass, which does not handle heat as well as borosilicate glass does.
