Product Description
Getting a dependable vacuum seal between a filter holder and its flask starts with the right stopper. This No. 8 silicone stopper fits the neck of common filtering flasks and holds tight under vacuum, so filtration runs steadily without leaks or the frustration of air bleeding in.
This listing is for catalog number 6168-4751: No. 8 Silicone Stopper. Silicone stays flexible across a wide temperature range and resists many chemicals better than natural rubber, so it holds up to repeated use. This stopper is a replacement component for the Heathrow Scientific glass filter holder systems, connecting the support base to a receiving flask. It also serves general stoppering needs where a No. 8 size fits. Order it from LIGHT LABS and keep your bench running smoothly.
