Laboratory Tweezers, how to choose them and at what price?

November 2, 2021

Among the various laboratory materials that we find, there are some that stand out more than others and that happens with the Laboratory Tweezers . Although it may seem that they are not so essential, the reality is that it is a very important tool in laboratories.

What are Laboratory Tweezers?

When we talk about Laboratory Tweezers we refer to an object of continuous use, which is essential to carry out various jobs. In other words, this instrument is of vital importance in laboratories.

Basically it allows us to efficiently take or hold any delicate element that we need without having direct contact with it. It is an instrument made of resistant materials , including metal.

Although it may seem simple, a Laboratory Clamp is an indispensable instrument. Keep in mind that holding objects is essential in laboratories, since in these places some objects have a high or very low temperature. So holding it with your hands can cause damage to the skin.

If we take all of the above into account, we can say that although it may seem like a simple instrument, it is actually a basic tool in laboratories. If this simple but effective device did not exist, the most probable thing is that a large number of inconveniences would arise when wanting to move and hold an object.

Laboratory Tweezers Features

Regarding the characteristics of this instrument, we can say that they are not complicated at all, so it is very easy to detect. In fact, this laboratory material has specific characteristics , which is why we were able to detect them.

To begin with, we must know that the Laboratory Tweezers have a main characteristic that would be to have a cylindrical rod. This being the one that allows connection to a support, by means of a clamp known as a double nut.

It is thanks to this piece that the laboratory tweezers can work, since they allow us to make the necessary adjustments. So we can take objects of a great variety of sizes . Apart from this, it allows us to rotate the instrument to a certain angle, which makes it easier for us to assemble the object that we are holding.

Moving on to the second part of this material we have the pliers . Which is composed of two arms and with which we can easily hold objects, which we can find in laboratories.

With all this in mind we can say that this instrument is not at all difficult to identify. Besides, when we know how it works, we can recognize it without any kind of problem.

What are the Laboratory Tweezers for?

As we have mentioned, this is basic laboratory instruments that are used to hold objects. Thanks to it, we can transport or take an item without problems. Something that could not be used otherwise.

But what is it that holds or carries this tool? The answer is very varied, some more common examples are the test tubes , burettes or laboratory funnels . Apart from those mentioned we can say the Laboratory Tweezers can also be used to make assemblies.

A clear example of this is in distillation systems, where all the substances in a mixture that is in a liquid state must be separated . The same is carried out by means of a process of selective boiling and condensation.

What are the uses of Laboratory Tweezers?

The places where this tool can be used are in laboratories, where it is widely used. In this place it can be used in multiple ways, the main one being to hold any type of object .

We must indicate that this is used in objects, which have a high temperature or some other characteristic that makes it impossible for us to come into direct contact with them. This can be either because it would represent a danger to our health , or as a means not to end up altering the sample.

With this tool we can get to hold different types of objects, including test tubes and burettes. But it also has another use, which is to allow the flow of a substance to be calibrated or to carry out a chemical process within the laboratory.

It should be noted that this tool has the ability to hold some objects due to its characteristics. Specifically for its double nut that is on a fine grid . Logically, this ability is also due to the fact that it has different types of presentations.

Types of Laboratory Tweezers

Because this instrument has a very varied use, a large number of models have been created that allow to do a much easier task. For example, when it comes to holding a test tube, it is not possible to use any laboratory clamp, but we must use the one that is specifically intended for that task.

With everything mentioned in mind we can say that there are different types of Laboratory Tweezers, among which we find;

Plastic tweezers

As its name indicates, this type of clamp is designed in plastic, which has a wide variety of advantages. To begin with, we can say that this is not a material that conducts heat . So it manages to avoid burns or injuries. We must bear in mind that the plastic Laboratory Tweezers have the ability to withstand temperatures above 200 degrees Celsius.

On the other hand, we must add that plastic has practically zero electricity conductivity . In this sense, if we work with electricity, this instrument is essential. To all this we must add that they are very resistant clamps, so they can withstand alcohols, ketones and some acids.

Three-finger tweezers

Another of the Laboratory Tweezers are those with three fingers, which are in fact the most common there is. It has two arms, where you can place two fingers and one finger on the other, hence its name. Another characteristic of this instrument is that it has a maximum opening of 180 ° and does not have a minimum distance.

Crucible tongs

Another type of Laboratory Tweezers is the crucible one that, as its name indicates, is intended to be used with crucibles . It has an appearance similar to that of pliers and works as if it were a pair of scissors.

Regarding its use, we can say that it works to safely heat laboratory crucibles. Regarding its elaboration, we can say that it is generally made of very resistant metals , since they are constantly exposed to high temperatures.

Test tube clamps

As its name indicates, this clamp is intended to deal with test tubes. It is usually used for heating, since it allows to maintain distance between the person and the flames. It should be noted that this tool is much more comfortable and simple to use than other tweezers.

Besides we can say that this instrument works with test tubes of any size, so it does not matter if it is very small or very large. Regarding their characteristics, they have curved arms to facilitate the fact of having to hold the tube in an effective way.

In relation to the materials used for its manufacture, these may vary, but they are usually wood, metal or plastic. It should be noted that depending on the material with which the clamp is made, it will be used for one task or another.

For example, if we must work with fire we cannot use wood, since although it is functional, wood is a combustible material. That is, it can end up burning too, which endangers the experiment and the user manipulating the clamp.

Wood clamp

This can be thought of as a kind of clamp for holding test tubes, since it is what it is normally used for. Due to this, it has one arm that is longer than the other, to maintain a certain distance between the test tube. We must emphasize that these are one of the most common tweezers out there, and they are usually used for analysis where boiling is needed.

Dissection Forceps

In this case we are talking about very important Laboratory Tweezers in areas such as biology and medicine. They can usually be found in dissection kits, where there are other tools that allow efficient cutting and extraction of samples from a living material.

Pinza fisherman

In this case we are talking about Laboratory Tweezers, used to hold or manipulate burettes in an optimal way. They are characterized by having a double fastening system, which is located in two nearby points.

Thanks to this feature we ensure that the burette does not suffer any kind of doubles. Keep in mind that bends in laboratory burettes are very common, especially when mounting with a thick laboratory clamp, so this is perfect for this task.
