This is a burette with Medical burette rubber stopper. It’s made for the medical industry. It’s a specialized part in medical testing and fluid control systems. It’s also closely linked with Orthopedic and Nursing Operation Accessories—especially in scenarios where precise reagent delivery is needed.It has a slender tubular shape. One end has a slightly larger diameter. This end is either rolled outward or flared like a trumpet. This design makes it easy to grip with fingers or align with the burette mouth for installation. The other end is relatively thin. It has a smooth, rounded closed design.Its length is usually a few centimeters. The length depends on the specifications of the burette it fits. The mouth diameter also has multiple specifications. These specifications let it fit burettes with different inner diameters. The inner diameter of the larger end can fit tightly over the outflow end of the burette. The size of the smaller end is designed to balance two things: sealing performance and liquid outflow control.It’s made of medical-grade elastic materials. It meets the basic performance standards of medical silicone seal. It gives reliable support to precise fluid control in medical testing.
Product Features
1. Functions
1)Burette Sealing:It’s installed at the liquid outlet of the burette. It works as a seal. When not in use, it stops solutions (like medical fluids, testing reagents) inside the burette from leaking or volatilizing. This makes sure the solution’s concentration and volume are accurate. It avoids problems—like medical test results or treatment effects being affected because of solution loss. Its sealing performance is the same as the core protective role of Medical Device Seals and Sterile Medical Seals. It meets the strict precision requirements of medical fluid control.
2)Liquid Flow Rate Control:During titration operations, you can control the outflow speed and volume of liquid in the burette flexibly. You do this by squeezing or releasing the rubber stopper. This makes it easy to add reagents or drugs precisely. It meets the high-precision requirements for solution addition in medical testing. It also lets you deliver drugs accurately in drug preparation and injection processes. This functional advantage goes beyond basic sealing. It’s different from Nursing Equipment Gaskets that only focus on static sealing.
3)Contamination Prevention:It separates the solution inside the burette from the external environment. It blocks impurities—like dust and microorganisms—from getting into the burette. This stops the solution from being contaminated. It makes sure the solution is pure and effective. This is especially important in medical testing and treatment scenarios where solution purity is extremely important. For example, titration of sterile medical fluids. This protective effect helps meet the hygiene standards of Orthopedic Sealing Parts and Surgical Instrument Seals.
2. Required Characteristics
1)Chemical Stability:It must stand different chemical solutions commonly used in the medical industry. Like acids, alkalis, and organic solvents. When it touches solutions with different chemical properties for a long time, it won’t have problems. Things like swelling, changing shape, being corroded, or having chemical reactions won’t happen. It keeps the rubber stopper’s shape and sealing performance stable. This stability meets the material standards of Medical Grade Silicone Seals and Medical Device Seals in harsh chemical environments.
2)Sealing Performance:It has excellent elasticity and flexibility. It fits tightly with the burette mouth. This forms a reliable sealing structure. Even under different temperatures and pressures, it can stop solution from leaking and gas from getting in effectively. This sealing reliability is as good as that of Medical Vial Cap Seals. It makes sure solutions can be stored and used stably for a long time.
3)Biocompatibility:It’s used in the medical industry. It may touch the human body or medical test samples. So the rubber stopper material must have excellent biocompatibility. It’s non-toxic, won’t cause allergies, and won’t irritate. It doesn’t harm human health. It also won’t react with medical samples or fluids—so testing or treatment isn’t affected. This is a basic requirement for all Ortho Care Components and Medical Device Seals that touch biological materials.
4)Wear Resistance:It’s often squeezed and inserted or removed. Even so, it has good wear resistance. Its surface won’t get worn or cracked easily. This makes sure the rubber stopper lasts a long time and its performance stays stable. This durability matches the service life requirements of Surgical Instrument Seals in high-frequency use scenarios.
5)Cleaning and Disinfection Adaptability:It’s easy to clean. It can stand common medical disinfection methods. Like high-temperature and high-pressure sterilization, or soaking in chemical disinfectants. After disinfection, its physical and chemical properties don’t change. It also doesn’t leave harmful substances that could contaminate the solution inside the burette. This meets the hygiene standards of Sterile Medical Seals in medical settings.
6)Dimensional Adaptability:It has precise dimensions. It also fits the burette mouth well. This makes installation and removal easy. It makes sure the connection is tight. It doesn’t affect the operational experience or sealing performance because it’s too tight or too loose. This dimensional precision matches the assembly requirements of Nursing Equipment Gaskets and Orthopedic Sealing Parts.
