Understanding the Critical Role of 6 Rubber Stoppers in Modern Applications

Rubber stoppers serve as indispensable components in laboratory, medical, and industrial environments. The 6 rubber stopper
variant specifically addresses high-demand scenarios requiring precise chemical resistance (up to 95% HCl compatibility) and thermal stability (-40°C to 220°C). Recent industry surveys indicate 78% of lab equipment failures stem from subpar sealing solutions, emphasizing the need for precision-engineered options like the rubber stopper for flask series.

Technical Advantages: Why Material Quality Matters

Premium-grade vulcanized rubber compounds demonstrate 3x greater longevity compared to standard silicone alternatives. Key performance metrics include:

• Shore A hardness: 50±5 for optimal sealing pressure
• Compression set: ≤15% after 72hrs @ 100°C
• Autoclavable cycles: 150+ without deformation

FAQS on 6 rubber stopper

Q: What is a 6 rubber stopper used for?

A: A 6 rubber stopper is a standardized laboratory accessory designed to seal glassware like flasks or test tubes. Its size (6) corresponds to specific ASTM dimensions, ensuring compatibility with equipment requiring airtight closures.

Q: How does a rubber stopper for a flask differ from others?

A: Rubber stoppers for flasks are pre-drilled to accommodate thermometers, tubing, or vents. They often have a tapered shape to fit conical flask necks securely, unlike non-customized rubber stoppers used in simpler sealing tasks.

Q: Can a rubber stopper flask withstand high temperatures?

A: Yes, high-quality rubber stoppers for flasks are made of heat-resistant materials like silicone or bromobutyl rubber. They typically endure temperatures up to 200°C (392°F), ideal for boiling experiments or autoclaving.

Q: Are rubber stoppers for blood collection tubes reusable?

A: No, rubber stoppers for blood collection tubes are single-use components to prevent cross-contamination. They’re designed with self-sealing properties for needle punctures and cannot maintain sterility after initial use.

Q: What size rubber stopper fits a standard blood collection tube?

A: Most blood collection tubes use 6 rubber stoppers (13mm diameter). These stoppers comply with ISO standards for vacuum tube seals, ensuring proper blood sample integrity during storage and transport.
