Basic Laboratory Glassware and Equipment

Mar 12 Read Mar 11 Read Jan 29 Read Jan 27 Read Mar 09 Read Mar 07 Read Feb 27 Read Feb 24 Read Glassware is found in abundance in laboratories and comes in all shapes and sizes.

Though it has become preferable in recent years to substitute glass vessels for cheaper, more durable and less fragile plastic materials, some substances and experiments or applications still require the use of glassware.

The reasons for these are manifold. Firstly, glass is relatively inert, meaning it will not react with the chemicals or substances placed inside and thereby upset or skew the results. It is also transparent, allowing for easy monitoring, and heat-resistant, allowing for high temperatures. Furthermore, it is easy to shape and mould into any form required. There is a vast variety of different glass apparatuses in a laboratory, and they can be manufactured from various types of glass depending on the purpose.

For example, quartz glass is resistant to high temperatures and transparent in specific areas of the electromagnetic spectrum. Heavy-wall glass is specifically strengthened to be used in pressurised experiments, while amber glass is darkened to block out UV and infrared radiation, thereby making it ideal for storing fluids.

With such an extensive range of glassware in the workplace and maximum precision required in all experiments, it is imperative that the equipment is kept in top-quality condition.

Though glass is resistant to high temperatures and most chemicals barring a handful , prolonged use over a protracted period of time will inevitably lead to degradation.

Here are some of the different types of glass instruments used in laboratories: Bulb and graduated pipettes. These are used to transport specific amounts of fluids from one place to another. These are used to dispense exact quantities of liquid into another vessel. Simple containers used to hold samples and reagents.

Volumetric flasks. Similar to beakers, these are used to hold samples, but usually come in a conical or spherical shape with a tapering neck. Specifically used to cool heated liquid or gas. These are used for distillation purposes. The tapered neck of a funnel allows easy pouring of a liquid into a narrow orifice. Petri dishes. Shallow dishes used to culture living cells.

Graduated Cylinders. Similar to beakers, these cylindrical vessels have volumetric markings to allow for monitoring of volume. Small bottles used to store samples or reagents. Used to hold items under a microscope for inspection and study. Stirring Rods. Used to mix solvents and samples together.

A container designed to absorb moisture from a substance. Drying pistols. Similar to a desiccator, the pistol is a more direct method of removing moisture from a sample.

Exceptional strength and stability. Brilliant transparency. Superior resistance to chemicals, contaminants, and drastic changes in temperature. Effective January 1, , customers will be able to download digital certificates as PDF files from the Corning Life Sciences online resource library simply by entering the item ID number and serial number from their PYREX product, and we will no longer provide printed certificates. This new process will improve customer convenience and reduce paper waste while delivering the same calibration information customers require.

From tumblers to champagne flutes, glassware is used to serve water, cocktails, beer, liquor, wine, coffee, tea and other beverages. With a wide variety of sizes and shapes, each one has a purpose. Alcoholic drinks are often served in specific types of glassware. Common barware include the following:. Stemware is a type of glassware that sits on a base and is typically used for formal family gatherings and holidays; the most well-known is the wine glass. Other types include the following:.

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. Many laboratories have training programs to demonstrate how glassware is used and to alert first—time users to the safety hazards involved with using glassware. The history of glassware dates back to the Phoenicians who fused obsidian together in campfires making the first glassware.
