Medical Bullet-Shaped Rubber Stopper



Product Description

This is a Medical bullet-shaped rubber stopper, widely adapted to fluid control components of devices such as micro-pipettes, medical samplers, and small testing instruments. As a key component ensuring precise equipment operation, it belongs to General Medical Sealing And Basic Components and Silicone Medical Components. Its overall volume is compact, allowing it to fit into the tight spaces of equipment; its dimensional accuracy meets medical-grade standards, ensuring a seamless fit with equipment interfaces; its surface is finely processed to be smooth and burr-free, avoiding residual liquids or impurities; the rounded arc design on the top fits the operating hand feel. Crafted from medical-grade elastic materials with high uniformity, it combines durability and biocompatibility, providing support for the accuracy and safety of medical fluid manipulation—fully complying with the performance requirements of Medical Seals and Medical Silicone Seal.

Product Features

1. Functions

1)Sealing and Protection: Used at the nozzles and interfaces of medical equipment, it plays a sealing role—preventing leakage of liquids (e.g., medical fluids, cleaning fluids) and gases, while blocking external dust, microorganisms, and other impurities from entering the equipment interior. This ensures a clean internal environment of the equipment, prevents contamination of precision components inside the equipment, and maintains normal equipment operation. For example, at the sample inlet and outlet of some medical testing equipment, it prevents sample leakage and external contamination. Its sealing reliability meets the strict standards of Medical Device Seals and Sterile Medical Seals for medical fluid systems.

2)Shock Absorption and Cushioning: During the operation of medical equipment, it can buffer vibrations and impact forces between components—reducing noise and wear caused by equipment vibration, and extending the service life of the equipment. For instance, when installed at the connection of moving parts of some medical equipment, it reduces collision damage between components. This buffering performance complements the functional advantages of Universal Gaskets and aligns with the durability requirements of Medical Equipment Basics.

3)Positioning and Fixing: It can be installed on equipment as a small component to position and fix other parts—preventing parts from shifting or loosening during equipment operation, and ensuring the stability and accuracy of equipment operation. This positioning function extends the application of Silicone Medical Components beyond pure sealing, supporting the overall operational reliability of medical equipment.

2. Required Characteristics

1)Biocompatibility: It must possess excellent biocompatibility—non-toxic, non-sensitizing, and non-irritating—since it may come into contact with the human body or medical samples. It must not pose harm to human health, nor undergo chemical reactions with medical samples or medical fluids that would affect test results or treatment effects. This is a fundamental requirement for all Medical Grade Silicone Seals and Medical Seals that interact with biological materials.

2)Chemical Stability: It must withstand common disinfectants, cleaning agents (e.g., alcohol, chlorine-containing disinfectants), and various medical fluids in the medical environment. During long-term contact with these chemical substances, it must not experience swelling, deformation, discoloration, aging, or other phenomena—maintaining the intact performance and appearance of the rubber tip, and ensuring the long-term effectiveness of its functions. This stability complies with the material standards of Sterile Medical Seals exposed to harsh medical environments.

3)Excellent Sealing Performance: It must have good elasticity and flexibility, enabling tight fitting with the connection parts of the equipment. Under different temperature and pressure conditions, it can effectively prevent liquid and gas leakage, forming a reliable sealing effect. This sealing performance is comparable to that of high-precision Medical Vial Cap Seals, ensuring leak-proof protection for medical fluid systems.

4)Wear Resistance: Its surface must have a certain degree of wear resistance. During daily use of the equipment, even if it rubs against other components, it must not be easily damaged—ensuring the service life of the rubber tip and the stability of its functions. This durability meets the service life requirements of General Medical Sealing and Basic Components in high-frequency use scenarios.

5)Dimensional Adaptability: It must have precise dimensions and good adaptability to the installation position of medical equipment. After installation, it must be firm and stable—without excessive gaps that affect sealing performance, nor improper dimensions that cause installation difficulties or hinder normal equipment operation. This dimensional precision aligns with the assembly standards of Medical Device Seals and other precision medical components.
