Laboratory Glassware Full Set For Chemistry Used For Scientific
Laboratory glassware refers to a variety of equipment, traditionally made of glass,
used for scientific experiments and other work in science,
especially in chemistry and biology laboratories. Especially
borosilicate glass, pioneered by Otto Schott, or sodalime glass are
preferred glass types for scientific experiments and other work in
science, especially in chemistry and biology laboratories.
Glass use in laboratory applications is not as commonplace as it
once was because of cheaper, less breakable, plasticware; however,
certain applications still require glassware because glass is
relatively inert, transparent, heat-resistant, and easy to
customize. There are several types of glass, each used for
different purposes. Borosilicate glass, which is commonly used in
reagent bottles, can withstand thermal stress. Quartz glass, which
is common in cuvettes, can withstand high temperatures and is
transparent in certain parts of the electromagnetic spectrum.
Darkened brown or amber (actinic) glass, which is common in dark
storage bottles, can blockultraviolet and infrared radiation.
Heavy-wall glass, which is common in glass pressure reactors, can
withstand pressurized applications
There are many different kinds of laboratory glassware items. Examples of glassware containers include:
1. Beakers are simple cylindrical shaped containers used to hold
reagents or samples.
2. Flasks are narrow-necked glass containers, typically conical or
spherical, used in a laboratory to hold reagents or samples.
Examples flasks include the Erlenmeyer flasks and Florence flasks.
3. Bottles are containers with narrow openings generally used to
store reagents or samples. Small bottles are called vials.
4. Jars are cylindrical containers with wide openings that may be
sealed. Bell jars are used to contain vacuums.
5. Watch glasses are shallow glass dishes used as an evaporating
surface or to cover a beaker.
6. Test tubes are used by chemists to hold, mix, or heat small
quantities of solid or liquid chemicals, especially for
qualitativeexperiments and assays
7. Desiccators of glass construction are used to dry materials or
keep material dry.
8. Glass evaporating dishes are used to evaporate materials.
9. Microscope slides are thin strips used to hold items under a
10 Glass petri dishes are used to culture living cells.
Examples of glassware used for measurements include:
1. Graduated cylinders are cylindrical containers used for
|2. Burettes are used to disperse precise amounts of liquid reagents.|
3. Glass pipettes are used to transfer precise quantities of
4. Glass Ebulliometers are used to accurately measure the boiling
point of liquids.
Other examples of glassware includes:
1. Glass tubes are cylindrical pieces of glassware used to hold or
2. Stirring rods are used to mix chemicals.
3. Funnels are used to get materials through a narrow opening.
4. Condensers are used to cool hot liquids or vapors.
5. Glass retorts are used for distillation.
6. Drying pistols are used to free samples from traces of water, or
Most laboratory glassware is currently mass-produced, but large
laboratories may employ a glass blower to construct specialized
pieces. This construction forms a specialized field of glassblowing
requiring precise control of shape and dimension. In addition to
repairing expensive or difficult-to-replace glassware, scientific
glassblowing commonly involves fusing together various glass
parts—such as glass joints and tubing, stopcocks, transition
pieces, and/or other glassware or parts of them to form items of
glassware, such as vacuum manifolds, special reaction flasks, etc.
Various types of joints and stopcocks are available separately and
come fused with a length of glass tubing, which a glassblower may
use to fuse to another piece of glassware.
