Buyer's Guide: Glass Test Tubes

Tips on Purchasing Glass Test Tubes

A: The use of glass jars and tubes is widespread in the scientific and medical laboratories all over the world. Glass jars and tubes have been used in chemistry labs for years, as have the glass test tubes. The quality and size of these jars and tubes will affect the quality and duration of the life of the scientific laboratory equipment. The glass used in the scientific glass jars and tubes must be free of defects, cloudy glass and spots and must meet strict requirements for chemical purity.

A: The glass test tubes and jars used in chemistry laboratories are made from different types of materials. They are usually made from borosilicate glass. The borosilicate glass of these high quality scientific glass test tubes and jars is usually 100% chemical free. These types of glass products are available in different sizes and shapes.

B: There are many types of glass test tubes available in the market. The commonest types are those that contain unbroken and uninterrupted polystyrene film. This type of material can be found in polystyrene sheets having other compounds added inside. These are known as polystyrene films which are chemically resistant. These glass test tubes may also contain other materials like EDTA, mercury, silver or cadmium.

C: Corrosion is a very common problem when handling glass tubes, jars or bottles. There are solutions that can help you combat this problem. For instance, it is possible to heat the sample tubes after usage so that they retain their freshness. You should also clean the glass test tubes after use so that they do not retain any kind of contamination. It is important to avoid exposing the sample tubes to salt water for curing.

D: Disposable plastic test tubes are also popular because of their ease of handling. These types of test tubes have a long shelf life and thus can be used indefinitely. Disposable glass test tubes are made of high quality plastic material that does not undergo chemical treatment during manufacturing. You should make sure that the plastic tubes have been made using high end thermoplastic polymers, otherwise they may undergo chemical reaction and degrade over time. These are available in different shapes, sizes and colors. The tubes may be easily available at online stores.

E: Cork stoppers are one of the best ways of cleaning your glass test tubes. The cork stopper helps you to remove dust, hair, and other particulates from your glass tubes. The stopper also ensures that the jar maintains its shape and integrity, even after repeated use. In addition, there are various sizes of cork stoppers available in the market, depending on the diameter of your jar. One of the most important things to keep in mind while purchasing these stoppers is that only cork stoppers should be used with certain types of jar.

F: Rubber stoppers are ideal for borosilicate glass test tubes. These rubber stoppers ensure that your jars remain airtight and do not allow any form of air to enter inside your jars. It is important to wash and dry these rubber stoppers before use. If these rubber stoppers are used without proper care, they may break or deform, causing harmful contamination inside your jar. The length of these stoppers is adjustable and available in different sizes, depending on the diameter of your jar.

G: Glass Test Tube Disinfection is very important. These chemicals can easily destroy many useful materials inside your test tubes, including plastic and rubber stoppers. These chemicals are very harmful and can even poison humans, especially if they are consumed by humans. To avoid this, you must always use glass containers when storing and handling chemical solutions. You must also purchase glass jars specifically meant for chemical reactions and other such uses from reputable dealers.
