Self sealing blood vial stopper
Without self sealing blood vial stopper blood test results would be significantly compromised. Vacutainer is a sterile glass tube, which is increasingly made of plastic too. This sterile tube is used for blood collection and that is why you can find it in medical laboratories. An indispensable part is the self sealing blood vial stopper. Vacutainer and self sealing blood vial stopper create a vacuum and thus facilitating the drawing of a predetermined volume of liquid. Without a vacuum seal, the volume of the liquid would change and this would compromise the results of blood tests. Vacutainer is important because it is sterile, but the most important thing to create a vacuum seal is a rubber stopper.
From this you can clearly conclude that each self sealing blood vial stopper must be made for a particular vacutainer or series of vacutainers, because otherwise it would not be possible to create a vacuum. So when you order a blood vial stopper from us, you need to know the exact dimensions of the vacutainer, so that we can do exactly what you need. We generally offer the option to choose different colors when ordering rubber stoppers, rubber grommets and other products, but this is especially important in the case of self sealing blood vial stopper. In this case, the color stopper indicates which additives are inside the sterile test tube, and the additives are necessary to obtain accurate results. If you used a test tube where the wrong additive is, it would mean that blood samples are unusable.
Self sealing blood vial stopper can be made of several different types of rubber to be equally effective. Silicone is certainly one of the most popular choices for customers, but you can also opt for some other rubber material, if you need some different material characteristics.
