2-hole stopper silicone

The laboratory equipment has to be diverse and plenty. Every piece has to be present for the efficiency of the institution. If there are missing pieces, your experiments will be compromised which will lead to results that are not controlled. This means that if you do everything the same way as before, the results will not match. Instead of having this worry, all you have to do is check whether you are missing something, and purchase it on time. Many people tend to forget about small pieces of equipment like the 2-hole stopper silicone pieces. 

They are essential pieces of the lab, and without them, you will not be able to do distillation processes and every other circular system. They are cylindrical pieces that are meant to be placed inside the openings of the glass equipment to cause a sealing effect. Without them, you will have leaks or gasses that will get away from the system uncontrollably. The reason that they have two holes, is to place the stopper on a larger container and have it connected with two separate pieces. For example, liquids will come in from one hole, and gasses will get out from the second hole. That way, you are creating a circular system that many experiments require. 

These 2-hole stopper silicone pieces as their name says, are made from silicone. This material offers the qualities that are needed for such purposes. Because it can withstand heat, it is great for laboratory testing. It can be sterilized using heat without causing damage, so it can be reused again. Also, it is both sturdy and soft which is great for fitment and sealing purposes. However, to make it work the best, you will have to get the right size of them. That is why it is recommended to get multiple dimensions so you can fit every glass item in your lab. If you require a stopper with special dimensions, our firm can produce them for you.
