MEDILAB Joint Clips are precision-engineered metal clamps designed to securely lock interchangeable Borosilicate Glass 3.3 joints in laboratory assemblies. They ensure stable, leak-free connections between glass components during distillation, reflux, extraction, and reaction processes. Their strong grip and corrosion-resistant construction make them essential for maintaining system integrity in both routine and demanding laboratory applications.

 Key Features

• Secure Joint Locking: Prevents accidental disconnection of ground-glass joints during operation.
• High-Strength Metal Construction: Provides superior holding force and long service life.
• Compatible with Borosilicate Glass 3.3 joints: Perfect fit for standard laboratory joint sizes.
• Chemical & Heat Resistant: Designed to withstand harsh laboratory conditions.
• Smooth, Non-Scratching Edges: Ensures safe contact with delicate glass surfaces.
• Easy to Attach & Remove: Quick locking mechanism for efficient workflow.
• Corrosion-Resistant Surface Finish: Maintains durability in chemical and humid environments.

Material Specifications

Clip Material: High-quality laboratory-grade metal
Compatible Joint Material: Borosilicate Glass 3.3

Properties:

• Thermal Stability: Withstands elevated temperatures typically used in heating mantles, water/oil baths, and hot plate setups.
• Chemical Resistance: Suitable for use around acids, alkalis, solvents, and vapours.
• Mechanical Strength: Designed for firm clamping without deforming or loosening during prolonged use.

Standards Compliance:

• Fits standard interchangeable joint systems conforming to ISO, DIN, and ASTM laboratory glass joint dimensions.

 Technical Specifications

• Available Joint Sizes: s13 to s41 (as per the standard size table)

• Dimensions: Machined precisely to match standard joint tapers.

• Tolerance: High-dimensional accuracy for consistent gripping pressure.

• Heat Resistance: Suitable for typical lab heating applications (non-flame contact).

• Packaging: Individually packed or bulk-packed for institutional and industrial supply. Protective anti-corrosion coating applied before packaging

• Accessories Included: None required; clips are ready for direct use.

 Handling & Precautions

• Ensure the clip is fully engaged around the joint before starting any heating or vacuum process.
• Do not overtighten; the spring mechanism is designed to apply optimal pressure automatically.
• Keep clips dry and clean after use to avoid rust formation.
• When cleaning, wipe with mild detergent and avoid abrasive scrubbing materials.
• Do not expose clips to direct flame or extreme temperatures beyond their rated limit.
• Inspect regularly for wear or deformation and replace if the holding strength reduces.
• Always ensure proper alignment to prevent stress on glass joints.

Applications

• General Laboratory Use: Distillation, refluxing, and reaction assemblies.
• Pharma & Biopharma: Secure connections in analytical, QC/QA, and formulation labs.
• Chemical & Petrochemical Research: Handling solvents, corrosive chemicals, and high-temperature reactions.
• Biotechnology & Life Sciences: Fermentation setups, extraction systems, and fluid handling.
• Academic & Research Institutions: Daily lab operations and teaching laboratories.
• Industrial R&D: Pilot plant systems and prototype glass assemblies.

Joint Clips play a crucial role in preventing joint separation, ensuring user safety, system integrity, and process continuity.
