Laboratory Glass Materials

November 1, 2021

There are many scientific advances that have been achieved thanks to the study and research of various phenomena, experimentation with the help of laboratory materials made of glass, wood, metal, or any other material is key, thus ensuring reliable results.

This group of instruments, necessary to carry out any experiment or research, are usually cataloged according to their nature, although the most used are those made of glass or those that have this as their main component, due to their high resistance to high temperatures.

What are Laboratory Glass Materials?

Next, I leave you this list so that you have faster access to the most popular Laboratory Glass Materials;

In any laboratory, different types of materials are usually used, among the most used are the so-called glass materials or laboratory glassware, made mainly with glass or with an alloy of it with other materials, making them equally resistant to high temperatures and sudden changes in it.

Among the most used glass instruments that are considered the most basic and associated in any physics, chemistry, medicine or biology laboratory are:

  • Beaker

It consists of a tank that is tubular in shape and is basically used to heat, dissolve and prepare substances or to transfer or measure any liquid. It has a flat bottom, they can be found high or low, graduated or not, there are different capacities from 100 ml to several liters, it can be heated but not directly over the flame, it must be placed on a grid.

  • Test tubes

Also known as a sample tube, it is a very abundant utensil in any laboratory, it is a small, cylindrical tube commonly the size of a finger that has one end open and the other closed and rounded. It is generally used to contain small solid or liquid samples and to carry out chemical reactions on small scales.

  • Dropper bottle with teat

This type of container is normally used to hold the solutions that are freshly prepared. It is accompanied by a dropper or dropper to facilitate qualitative reactions , transferring small amounts of liquids and placing them drop by drop. They come in different capacities and colors to protect mixtures that are usually sensitive and that can be affected by ultraviolet rays.

  • Volumetric flask

The volumetric flask is a container used to measure the volume of solutions with complete precision . It has a flat base and a narrow and high neck, which increases the timeliness of the measurements, since a small change in the volume of the solution will be accurately reflected in the height that the liquid will have in the neck of the flask.

  • Test tube

It is a transparent and volumetric tube with a sealed base that allows it to be held, it has a graduation indicated with a series of engraved marks that go from the base and the entire cylinder to the maximum of it, starting from 0 ml.

In its upper part it has an opening through which the liquid to be measured is introduced and there is a spout that allows the liquid to be poured easily, without running the risk of spillage. There are different sizes, generally they are 25 to 50 ml, but there are also some that can measure up to 2000 ml.

  • Cold finger

This part is used in the laboratory to generate a localized cold surface, is usually used in a sublimation apparatus, and can be used as a compact version of a reflux condenser for either distillation or chemical reactions .

This tool consists of two parts, one that is like a test tube with a side tab and a tube bent at a right angle that is placed inside the previous one. This is placed inside an external conduit in which the substance to be sublimated is put, leading a side outlet to a vacuum pump.

  • Glass funnel

The funnel is an instrument found in all laboratories and is used for various tasks . It is used to mix the different compounds of a solution, to transfer chemical products from one place to another and it is also usually used to filter separating solids from liquids, in this case a pleated or conical paper filter must be placed.

In laboratories, funnels of different sizes are usually found and you can even find the settling funnel, which allows you to regulate the amount of liquid to be filtered or transferred.

  • Graduated Pipette

It is an instrument used to measure the volume of dispensed liquids , although not with as much precision as is measured with the volumetric pipette. It is a transparent tube that ends in a conical shaped tip, it has a series of marks that indicate the different volumes.

  • Watch glass

This is a concave-convex circle shaped glass sheet that is generally used in laboratories to weigh solids. It is also widely used to cover any solution momentarily to prevent dust from falling on it , since by not closing hermetically, it allows gas exchange.

  • Petri dish

It is a circular container with a lid, of a larger diameter, that covers it but not hermetically. It is used to place and grow samples of cells , tissues and bacteria, observe how seeds germinate and be aware of the behavior of microorganisms.

It is important to know that before starting to work in any laboratory you must have the knowledge of the necessary basic material and its handling. It is essential to locate and familiarize yourself with the available security measures, in addition to knowing its duly marked location.

Laboratory Glass Materials

Laboratory instruments are all those materials such as containers, meters, containers and many other tools, which are needed to perform the analysis and synthesis in the environment of the various works that are carried out in a laboratory.

These materials can be made up of very varied elements, but the most used are those made of glass, due to their resistance to high temperatures and their variations. Its use depends on the function to be performed. Apart from those already mentioned, others, of equal importance, can be found when conducting an experiment or research.

  • Retorta

In every laboratory it is very common to find a retort, it is a spherical glass container with a very elongated neck that has a certain downward inclination. It is used for the distillation of any substance .

The liquid is placed inside the glass and it is heated, the neck will act as a condenser allowing the vapors to flow through it, to store it a glass must be placed at the end.

  • Refrigerant pipe

A condenser or cooling tube is a laboratory tool whose purpose is to condense the vapors that come off the distillation flask, through a cooling liquid that circulates through this tube, usually this liquid is water.

  • Glass stirring rod

The stirring rod is a piece of solid, thin glass used to stir chemical solutions in the laboratory. It has rounded ends and in some cases it has a plastic on one of its tips that is used to drag any remaining solute that remains on the walls of the container.

It is also used to introduce any liquid substance that can have a high reaction through runoff, in this way any type of accidents can be avoided.

  • Crystallizer

This instrument is a short glass container with a wide base that allows the solvent of any solution to evaporate quickly, thus crystallizing the solute, it is also used as a container and as a lid.

  • Kitasato

The kitasato or kitasato flask is another of the glass materials that can be found in a laboratory, it is like an Erlenmeyer flask but with a lateral nozzle or with a detachment tube, it is used to carry out distillation experiments or with water , filtrations vacuum, gas collection and volume displacement.

Glass is one of the most used materials in chemistry, physics and biology laboratories, it is very common for these to be heat resistant to avoid accidents when exposed to the flames of the burner or barbecue.

Glass Laboratory Materials and Their Use

The glass instruments in a laboratory are used for any development or analytical determination of an experiment, knowing and being clear about their handling and maintenance. These materials are created to measure volumes, store, transfer and distill any solution .

Glass instruments are the most widely used and oldest in physics, chemistry and biology. They are generally refractory since many of them are exposed to different temperatures through flames, lighters and other forms of heating, which require that the utensils be of good quality.

Something extremely important for the use of each of these instruments is precision, it is necessary to know the veracity of each one of them in order to know which one is going to be used in a certain study or experiment that is going to be carried out.

What are Glass Laboratory Materials for?

Glass materials in a laboratory serve multiple uses, many of them are graduated and others are not , some are used to measure quantities and volumes, to carry out experiments, formulas and quality control.

In general, they are tools that resist high temperatures, since many of them heat up, they are also invulnerable against bases and acids. In them you can easily observe the changes that occur during the reactions.

The glass materials found in a laboratory can be classified into two categories , the well-known common glassware, which comprises beakers, funnels, round-bottom and flat-bottomed balloons, condensers, test tubes, glassware. watch, stopper bottles, among many others.

In addition, those of high precision volumetric glassware are obtained that are usually more expensive due to the time that has been invested in the calibration process, among these are those that are used to measure volumes with accuracy, in these they are indicated if it is to pour or to contain and the temperature at which it has been calibrated.

Importance of Laboratory Glass Materials

Glass laboratory materials are one of the essential elements in a laboratory, the advantages are their manageability, their inert nature, their transparency, their resistance to heat and the possibility of designing custom fractions, but it should also be clear that its biggest drawback is fragility .

For optimal experimental knowledge, it is essential to have the necessary materials, machines and instruments of good quality, in order to guarantee a longer useful life and achieve the expected results in the investigations . Although it should be noted that these are usually very expensive and somewhat complex to handle.

In many cases, it has been proven that the use of low-quality materials in laboratories has had a negative impact on investigations, altering results and creating complications. This leads to the scientist having to work much more to achieve the expected results.

A simple to use instrument can cause serious damage to the property or physical integrity of the user, if it is not used properly. For this reason, certain care must be taken in its handling and working with the optimal conditions, the necessary safety measures and the appropriate protection to effectively avoid all types of accidents.

When choosing a laboratory material it is important to consider the use that will be given to it and consult its technical specifications, so you will have total assurance that it is fully functional and the risks that may arise from its use will be reduced in such a way. .
