Erlenmeyer flask rubber stoppers
Erlenmeyer flask rubber stoppers are essential to almost every kind of lab work. In fact, without these small tools, storing sensitive chemical ingredients would become downright impossible. One of the reasons why most labs choose rubber as their preferred material for sealing Erlenmeyer flasks is their resistance to all kinds of aggressive substances, which are often used in laboratory work. Of course, not all Erlenmeyer flask rubber stoppers are made equal. They are usually a mixture of different rubber materials, which should be considered depending on the substance’s specific characteristics that require careful handling. If you’re unsure which type of rubber is the most suitable for your particular needs, we suggest seeking assistance from an expert before making your order. In regards to ordering your Erlenmeyer flask rubber stoppers, the best course of action is purchasing them in bulk, especially when it comes to large-scale projects. In this way, you’ll get the best possible price-to-quality ratio and ensure you never run out of rubber stoppers in your lab or factory.
Besides their resistance to strong, aggressive chemicals, Erlenmeyer flask rubber stoppers can withstand excessive external conditions such as extreme temperatures and exposure to corrosive liquids. Again, that makes them a perfect solution for any lab or factory that needs to store a wide range of hazardous or reactive substances. As you already know, many chemical ingredients need to be held in highly controlled environments, which requires the use of sturdy and durable materials for these purposes.
Luckily, today you can find a wide range of options available on the market, especially when it comes to sizing, diameters, or in some specific cases, shapes and colors. If you can’t find a rubber stopper that fits your Erlenmeyer flasks properly, you can always make a custom order with a supplier of your choice.
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.
Custom colors are available to your Pantone color code. Include the code in your inquiry.
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.
