Bolium lets you store and transport liquids more efficiently than ever, thanks to the glass or plastic tubes with caps we offer in this category. These tubes will be an ideal packaging solution for a wide range of applications. What is more, thanks to the screw caps and the airtight closure they provide, you will never have to worry about accidental spills. Bolium offers you a wide range of sizes and pack quantities, so that you can store all types of liquid samples in various volumes as effectively as possible.
At Bolium, we take quality very seriously, and the tubes offered here for packaging your liquids, whether glass tubes or plastic tubes, represent the best value for money. Are you torn between the advantages of glass and those of plastic for packaging your liquids? That is quite understandable, which is why we will try to look at both below.
Glass tubes are an ideal solution for packaging many liquids because they are impermeable and non-reactive. This means that the liquid in the tube will not be affected by the glass itself; in other words, it will not degrade or react with the glass over time.
Plastic tubes are also an excellent solution for packaging liquids, because they are lighter and less expensive than their glass counterparts.
In reality, choosing well between the advantages of the glass tube and those of the plastic tube depends entirely on your needs and objectives.
While, for many people, glass tubes and plastic tubes with caps will be used in medical and scientific laboratories (the famous test tubes), they can just as well be put to good use in many situations other than taking samples and carrying out tests in laboratories.
For example, they can be considered for floral decoration, as a bud vase or for an arrangement; in gastronomy, to store oils or dressings in an attractive container that is out of the ordinary; or in the arts, to test colour mixes, for example.
