Introduction To Glasswares Used In Pharmaceutical Laboratory


Beakers, cylindrically shaped containers that store reagents and samples in sizes from 10 to 4000ml, can be used to store them. Beakers are the most commonly used glass equipment in laboratories. They are used to store solids and liquids and for pouring and decanting fluids.
The beaker’s flat bottom makes it easy to place on flat surfaces such as a hot plate or lab bench. It’s easy to pour liquids into other containers because of the spout. Additionally, the large opening makes it possible to add materials to your beaker.


Flasks can be narrow-necked glass containers made of conical or square glass used in laboratories to keep samples or reagents. Examples of flasks include the Erlenmeyer flask, Florence flask, and Schlenk Flask.
They help swirl contents without spitting. They come with stoppers. They are fitted with stoppers. An Erlenmeyer flask features a flat top, which is helpful for direct heating. A Florence flask comes in two sizes.

Test tubes

Test tubes are cylindrical lab equipment that is relatively smaller than beakers. Chemistry professionals use test tubes to store, mix, heat, and preserve small quantities of liquid or solid chemicals. They are beneficial for qualitative tests and assays.
They can be used in observational processes.

Test tube holders

A is used to hold test tubes. It is used to hold a test tube when it is hot or should not be touched. Structurally, the jaws of a test tube holder are self-closed by a spring.

Test tube stands

For easy handling and spillage prevention, test tube stands or racks support tubes upright and aligned. It is an essential tool in any biology and chemistry lab.

Graduated Cylinders

Graduated cylinders, cylindrical containers of thin and tall size used for volumetric measurements, have volumetric markings that allow for volume monitoring. It’s used for measuring liquid volume semi-precisely. They measure delivery volumes more precisely than a flask or flask graduated cylindrical.

Volumetric flask

Volumetric flasks are similar to beakers. They can hold samples and come in conical, spherical, or tapered necks.
To make precise solutions that are four-digit precision, volumetric glassware will be required.
Volumetric flasks measure specific volumes of fluid. They have an etched marking on their neck that displays the precise volume at the desired temperature.


Glass pipettes allow fluids to be transferred precisely from one place to another. These are also volumetric glassware that measures liquid volumes and can be used to dispense liquids. They are one of the most precise laboratory ware. The solution can be drawn using a pipette lamp. Micropipettes are also available if you’re dealing with small amounts, such as 1microlitre to 1,000microlitres.


Burettes are similar in appearance to graduated cylinders. They have a valve on end, used to disperse exact amounts of liquid agents, often for titrations. These burettes can be identified according to dispensing volume, resolution, or accuracy.

Petri dishes

A Petri dish is a cylindrical, transparent, and small-sized dish that has a transparent lid. It can be made in plastic or glass. Petri dishes are transparent cylindrical lidded dishes made of glass or plastic that can contain a thin layer (or both) of agar to allow for the rapid growth of microorganisms.

Stirring rods

Also known as glass rods stirring rods can be used for mixing liquids and chemicals in laboratory settings.


A funnel’s tapered neck makes it easy to pour liquids or powders into small containers. They have a narrow necks.


A thermometer is used to measure the temperature of liquids and other compounds. To measure the temperature taken, thermometers are equipped with a calibrated scale.

round-bottom flask

A round-bottom flask is also known as an Erlenmeyer bulk or round-bottomed flask and can be used for heating or boiling liquids uniformly. They are used chiefly in distillation experiments because they have a cylindrical neck and a spherical top.

Evaporating Dish

Evaporating plates are made from glazed porcelain. The dishes are heated and evaporated liquids with high heat. Some evaporating dishes have a spout that can be used to pour liquids.

Separatory funnels

Separatory bottles are a type of chemistry glassware that has a wide top and narrow bottom. This allows for a stopcock. These are used to separate liquids of different densities and solubilities.


A spatula is a broad, flat, flexible blade that mix, distribute, and lift material such as foods, plaster, paints, and drugs.

Iodometric flask

These flasks will be used to determine the iodine level. Each flask features a ground socket and a cup-shaped cap. The total cup capacity for all flasks within the range is 20ml.

glass viscometer

Cannon-Fenske Routine Viscometer is an inexpensive, rugged viscometer. This viscometer works best if the liquid being measured is transparent. To measure transparent liquids, you can also use the Ubbelohde viscometer and other suspended-level viscometers.


A stalagmometer can be described as a glass instrument that measures the tension of liquids. It is often used to determine alcohol concentration.


A container for measuring the density of a liquid/powder. It is usually a container with a defined volume. It was often equipped with a thermometer, indicating its contents’ temperature.


A container is designed to absorb moisture from a substance. Desiccators of glass construction are used to dry materials or keep materials dry.


Condensers cool vapors, cool them down and turn them into liquids.


A sieve, fine-mesh filter, or sift can separate unwanted elements from desired material.
