Pipettes are laboratory instruments/tools used to transfer liquids, usually chemicals from one place to another. They are used very extensively in experiments that involve reactions of acids and alkalis, so known as titration experiments. Accuracy is one of the salient features of these tools and they come about owing to many features. One of these is the precise calibration of the tube that allows accurate markings and liquid capacity to be noted. Another feature is the pipette filler that is available separately but from the same manufacture that one may decide to buy the tube from. These allow safe and accurate filling of any chemical. A very important sub instrument available with this is the pipette tip that is places towards the end or suction area of the tool and helps in accurate and easy injection of fluids.
Pipette tips are disposable. This is good news for many users as a lot of experiments do require the use of the tools without a protrusion. This will help flexibility with which scientists and chemists can perform experiments. Although the user may buy any form of tip they want, but experts highly recommend that it be bought from the same manufacturer they got the pepittor from as it will fit in properly as required and will also be of the desired accuracy. The manufacturer can also guarantee or offer a warrantee offer on any items that may be returned in case they do not work as advertised.
Pipette tips are available in many sizes and forms. They can be available in sizes depending on the size of the tool they have to be attached to. So for instance if the tube is wider in diameter, the tip will be made accordingly. This is exactly why experts ask for the same manufacturer's pipette and tip, because they fit together more effectively. They are prepared in sizes exactly the same as the pipettes are manufactured in order to ensure perfect functionality.
The varieties that these tips are available in include sterilized, non-sterile and filtered tips. They come in five together in a single tray. The sterilized variety is actually more common in experiments that involve the use of medicine and vaccine. Also when the study of blood is involved, all possible care needs to be taken to ensure that pathogens and bacteria do not contaminate the culture or whatever experiment is under study. Filtered variety is used to extract liquid that contain tiny solid particles for example a mixture of sand and water. The filter acts as a permeable layer that leaves out any unnecessary particles. A non-sterile form is the simplest form of tip that is available. It is the cheapest too, given that no extra work is put into it. The tip works fine for regular experiments and all kinds of liquid.
The tips are made of hard or good quality plastic. The reason for that is that plastic is a non reactive matter so it does not alter any acids or alkalis. The tips are also made of part plastic, part glass or even rubber. These also ensure that the tip flexibly fits the tube without breaking and it also ensures that it is fit in tight.
The introduction of these extras has made experimentation a lot easier compared to earlier times along with this experimentation has become a lot safer as well. It has allowed experimenters and many other to use precision and transfer their liquids under study to small areas. The nozzles of the tips allow the liquid to escape but not too quickly allowing more control and precision.
