Piseta

November 1, 2021

All the instruments that are part of a laboratory are extremely important, regardless of the role they play, since it is all about teamwork. The tank, although simple in its appearance, is a very useful instrument in biology or chemistry laboratories.

The tank is an instrument designed primarily to maintain hygiene conditions, so important in these spaces, hence its importance and the need to know each of its aspects.

What is a T-shirt?

The tank is also known under the names of washing flask and  washing flask . It is a common bottle that has a built-in straw-like outlet, which contains a solvent inside, mostly distilled water.

The primary function of this instrument is to clean or wash other instruments, to avoid contamination with the samples placed in these places.

What is a T Shirt for?

The tank is used for many related activities, mostly cleaning and maintaining the phytosanitary conditions of other laboratory instruments. To name the main functions we have:

  • Clean all the plastic materials that are in the laboratory and of different qualities.
  • Cleaning of glass instruments that deserve a more delicate cleaning.
  • Clean instruments that are delicate at least what they have
  • Rinse the capacity for the preparation of different solutions.
  • It allows saving costs in the cleaning of the bottles, since being specialized it has a system that saves in large quantities product and time.
  • It is the perfect for cleaning frosted glass.
  • It primarily cleans beakers, flask and test tubes.
  • It has a function other than cleaning, which is to dissolve substances with distilled water or some other solvent.
  • In some cases, a different nozzle is installed that allows it to collect liquids and keep them isolated within the tank of other compounds.

The t-shirts have a universal applicability since they can fulfill a great number of functions, to earn the cataloging of being a complete and indispensable auxiliary instrument for any laboratory worker.

How does a T-shirt work?

The operating mechanism of the tank will vary depending on the purpose for which it will be used, whether it is for washing or for collecting liquids.

If you lean by the primary, that is cleaning instruments simply have to unclog the neck the squeeze bottle and pour the solvent , which may be ethanol, distilled water, hexane, methanol, among others. Then you proceed to seal the t- shirt again.

If the tank is made of plastic, you can press in the middle of the bottle to expel the cleaning liquid. In the case of those that are made of glass, you have to hold it by the neck and press down on the straw and this will expel the liquid.

There are some t- shirts that consist of two straws, one to blow the liquid, once the t-shirt is filled with the solvent, and another straw through which the liquid will come out.

On the other hand, if you want to collect a liquid with the tank, what you have to do is change the nozzle for a specialized one to absorb. In this case, you just have to squeeze or suck, depending on the model of the t- shirt .

Uses of the T-shirt

The uses of the tank are related to three axes, fundamentally, which are nothing more than the distribution of liquid in controlled portions, washing of instruments and absorption of liquids.

The uses extend mainly to laboratories, since they allow the removal of waste, remains or toxic elements from the instruments, to purify them in such a way that they do not contaminate the new mixtures.

In addition, having a straw at its outlet allows small portions of liquid to come out, so you can distribute it to other instruments, for unlimited functions.

If there is a liquid end product left, from a reaction, or just a portion that you want to store left over, just change the nozzle and voila, you can do it without problems. As we have seen, it is all about laboratory procedures for the processes of transformation, creation, elimination or experimentation of substances.

The tank is an instrument of indisputable utility within the laboratory. Its function guarantees that the procedures performed in it have the necessary asepsis, ensuring reliable results.

Types of Piseta

There are many types of tank that you can work with in the laboratory and one model differs from another by the manufacturing material, the solvent it uses or simply by the operating mechanism.

Next, I share the main types of t-shirt that exist and with which you will surely come across in any laboratory, these are:

According to the manufacturing material

Not all t- shirts are made of the same material, because they comply with the safety conditions required by solvents. This is why we see that they are made of plastic or glass.

    • Polyethylene Plastic

It is a more economical material and allows to have a tank with simple functions and whose solvents are not reactive or of high temperatures that damage this material.

    • Glass

It is a more resistant material with which we can work the elements that polyethylene plastic could not support.

    • Nalgene plastic

It is a specialized plastic capable of withstanding almost any solvent and best of all, it always maintains a purity inside, which is ideal for microbiology work .

Depending on the solvent you use

Under this classification, a color code has been established on the caps that indicate what type of solvent you can place in that tank, specifically.

    • Blue top pads

They are the ones that specialize to contain only distilled or demineralized water in this case, inside.

    • White capped pisetas

It is the one most frequently used in laboratories and although you can also use distilled water, its original function is to contain sodium hypochlorite or, failing that, ethanol.

    • Yellow top t-shirts

They are specialized to contain only isopropanol.

    • Green lid pods

This type of tank is intended to contain methanol.

    • Red capped pisetas

This is one of the most resistant models and is capable of containing acetone as a solvent.

According to the operating mechanism

It refers to whether it is unilateral or dual, as we mentioned earlier because it will depend on the number of straws you have.

    • Single outlet

They are the ones that have a single straw which we activate to stimulate the exit or entry of liquids.

    • Two-way

This uses a propulsion mechanism in the attached straw that is why we blow or suck, to let out or allow the entry of some liquid.

Despite being a simple element, the t-shirts are well differentiated to be able to fulfill all the cleaning tasks in any laboratory with excellence.

Characteristics of the T Shirt

The tank is a particular instrument that has a series of particular characteristics that differentiate it from any other instrument found in the laboratory, the main ones being the following:

  • This bottle is only made from specialized plastics or glass.
  • Its base is cylindrical in shape and has a straw-like outlet, very long and curved.
  • Only inside they can they contain solvents as some other different compound can be contaminated inside or, simply, will damage the container completely.
  • The parts of the tank are three, a cylindrical container, a screw cap and the thin tubular extension that comes out of the container and has a small opening at the end for the exit of liquids.
  • Some models may have two outlet tubes.
  • Its use is almost exclusively for laboratories that can be of different branches, be it chemical, physical, biology or medical.

It is an easy-to-understand instrument, it has a wide number of properties that allow it to carry out these aseptic tasks , taking care of all the details in terms of operation and structure.

Importance of the T Shirt

The tank from the unknown has had a significant importance in laboratories around the world, since it facilitates the cleaning of other equipment in this field, which, as we know, is essential for any process that is carried out.

In addition, it is a device that allows to contain solvents that dilute substances in different reactions, without having any contact with it, as well as to absorb those that we need to store.

The tank is undoubtedly a first-hand instrument , since it intervenes in the various processes, prior, in the development and at the end of a laboratory experiment.  Best of all, it is extremely easy to use, which makes it one of the most practical.

Recommendations about T-shirts

To ensure that the life of the tank is lengthened, it is necessary that you comply with a series of special cares and recommendations, to achieve this and even to ensure the correct operation of this instrument. What you should do is the following:

  • Be guided by the caps and their colors to know which solvents to put inside because a mistake can damage the whole If in this case, you have trouble learning the color nomenclature you can place the names of the solvents with a label on the outside.
  • To handle solvents that generate gases, it is necessary for the tank to have an outlet that allows the liquid to escape.
  • They should be thoroughly cleaned on a regular basis with distilled water or some permitted chemical component so that they are not contaminated.
  • This instrument must be within the reach of any laboratory personnel to be used immediately.
  • Take the instrument with great care and when there are elements at high temperatures, hold by the neck or where it is screwed.
  • It is necessary to know the correct operation of this instrument as it is used regularly.
  • When you are going to change the nozzle for one that absorbs you must be careful when screwing.
