MEDILAB Expansion Adapters are precision-designed glass connectors that join laboratory apparatus with different joint sizes, ensuring secure, leak-free assembly. They play an essential role in setups where instruments or glassware require a transition between larger socket joints and smaller cone joints. These adapters support smooth workflow, prevent system incompatibilities, and maintain the integrity of analytical, chemical, and research operations.

Key Features

• Differential Joint Compatibility: A larger socket joint at the top and a smaller cone joint at the base for seamless connectivity.
• Precision-Ground Joints: Ensures airtight, accurate, and reliable fit in lab assemblies.
• High Durability: Resistant to thermal shock and chemical corrosion for long operational life.
• Leak-Proof Performance: Maintains tight, stable joints even under vacuum or pressure-related applications.
• Wide Joint Options: Additional joint sizes can be manufactured as per customer requirements.
• Smooth and Uniform Finish: Prevents joint sticking, ensures ease of handling, and supports repeated use.

Material Specifications

Material: Borosilicate Glass 3.3

• Excellent Thermal Resistance: Low coefficient of expansion (~3.3 × 10⁻⁶/K), ideal for heating and cooling cycles.
• Chemical Stability: Resistant to acids, solvents, alkalis, and laboratory reagents.
• High Mechanical Strength: Provides reliable performance even during frequent joint assembly/disassembly.
• Compliance with Global Standards: Manufactured as per applicable ISO, DIN, and ASTM requirements for laboratory glassware.

Technical Specifications

• Available Joint Sizes: As per the standard size table
• Design: Larger socket joint (top) and smaller cone joint (bottom).
• Tolerance: Precision-ground joints maintained within standard laboratory tolerance limits.
• Dimensions: Vary as per joint configuration; tailored dimensions available on request.
• Calibration: Not applicable (glass joints are uncalibrated components).
• Optional: OEM marking, custom branding, and joint size engraving are available.

Handling & Precautions

• Handle with care to avoid scratches or impact on ground joints.
• Always apply a suitable joint grease if required for airtight sealing or vacuum applications.
• Clean with mild detergents; avoid abrasive cleaning tools that may damage joint surfaces.
• Compatible with autoclaving; avoid sudden temperature shocks (e.g., moving from flame to cold surface).
• Do not force joints apart—use gentle twisting if joints become tight.
• Store in padded compartments to prevent chipping or joint wear.

Applications

• Chemical, Analytical & Research Laboratories: For connecting apparatus with mismatched joints.
• Pharmaceutical & Biotechnology Facilities: Ensures compatibility between glass assemblies during reactions, distillations, and sample transfer.
• Quality Control / Quality Assurance Labs: Provides standardised connections for routine testing setups.
• Academic & University Laboratories: Common in organic chemistry, distillation rigs, teaching setups, and demonstration assemblies.
• Industrial R&D Centres: Supports custom-built systems, pilot-scale operations, and specialised workflows.
