Silicone stopper two hole
You will find silicone stopper two hole as a very important part of laboratory equipment. Almost every laboratory has at least one silicone stopper two hole, and most laboratories need a very large number of this type of stopper due to the very versatile application. According to our clients who are ordering silicone stoppers for their labs, silicone stopper two hole is suitable for all general laboratory uses and that is why this is one of the rubber stoppers for which we have the most orders.
Different specifications require different dimensions, and in our offer you can find a large number of different dimensions. We also offer you the opportunity to order a silicone stopper size that suits you. Sizes of not only stoppers but also holes vary for different applications. The size of the silicone stopper depends on the diameter, length and shape of the laboratory flask or some other type of laboratory equipment where you need to install the rubber stopper. On the other hand, those dimensions do not play such an important role when choosing the diameter of the hole, which can be 2, 3 and 4 mm diameter, as well as some other sizes. You choose the diameter of the hole to fit the instruments you need to insert into the laboratory flask through that hole.
As two hole stoppers are most commonly used in the laboratory, then silicone is the best choice of material. Silicone has extremely high chemical stability, which means that it can withstand laboratory conditions without losing its characteristics. And it can withstand such specific conditions for a very long time. An additional advantage of using silicone in laboratory conditions is the ability to be exposed to very high temperatures, also over prolonged time. Silicone and FKM have the best chemical stability, and silicone withstands even greater temperature ranges.
Stopper & Plug Size Catalog
Compare four stopper profiles and check the selected part dimensions against your opening and available depth. Each profile has its own drawing and dimension meanings.
RST T-Shaped Plugs
Match stem diameter A, flange diameter B, stem length C and flange thickness D. E refers to the underside recess; use the selected row and approved drawing to confirm the actual profile.
RSA Tapered Corks
Compare large-end diameter A, small-end diameter B and Height, in mm. The mating bore and required seating depth determine where the taper contacts the opening.
RSB Undercut Plugs
Compare neck diameter A, flange diameter B, flange-to-lip distance C and flange thickness D. Check panel thickness and rear clearance. E refers to the underside recess.
RSD T-Shaped Stoppers
Compare stem diameter A, flange diameter B, stem length C and head thickness D, in mm. Check the seating surface and available depth as well as the hole diameter.
