Turnover Flange Septa are precision-moulded sealing components designed for laboratory glassware such as flasks, tubes, and bottles. They provide a secure, leak-proof barrier while allowing controlled access for needles, probes, or sampling devices. Manufactured from high-quality silicone or natural rubber, they ensure reliable sealing performance essential for sterile workflows, chemical handling, and analytical procedures.

Key Features

• Excellent sealing efficiency for preventing leaks, contamination, and sample loss
• Flexible turnover flange design ensures a firm grip on glassware openings
• Chemical-resistant and thermally stable (varies by material)
• Compatible with vacuum operations and sterile techniques
• Durable, reusable, and easy to install/remove
• Available in multiple sizes to suit various laboratory glassware

Material Specifications

• Material Options: Silicone rubber / Natural rubber
• Thermal Properties: Silicone: High-temperature stability, suitable for autoclaving. Natural Rubber: Good elasticity and mechanical strength
• Chemical Resistance: Silicone: High chemical and solvent resistance. Natural Rubber: Resistant to mild acids and bases
• Certifications/Standards: Manufactured in compliance with common laboratory quality standards (ISO & ASTM moulds where applicable)

 Technical Specifications

• Available Sizes: Wide range to fit standard laboratory flasks and tubing ports
• Dimensions: Customised diameters and flange profiles based on application
• Accuracy/Tolerance: Precision-moulded for consistent sealing performance
• Accessories Included: Supplied as individual units or assorted packs (as required)

 Handling & Precautions

• Ensure proper fit to avoid air leakage or vacuum loss
• Clean with mild detergents; silicone variants are autoclavable
• Avoid exposure to harsh solvents when using natural rubber models
• Do not use damaged or worn septa; replace them immediately for safety
• Store in a cool, dry place away from direct sunlight to maintain longevity

 Applications

• Ideal for microbiology labs, analytical labs, and chemical processing units
• Used for sealing Erlenmeyer flasks, filtering flasks, reaction vessels, and sample containers
• Suitable for pharmaceutical QA/QC labs, biotech research, academic labs, and industrial testing environments
• Ensures contamination-free sampling, liquid transfer, fermentation work, and controlled laboratory operations
