Glass Adapters

Glass adapters play a crucial role in creating secure, leak-proof connections between different laboratory glassware components. Whether you’re setting up a distillation system, connecting hoses, or working with multiple joint sizes, adapters make your workflow smoother, safer, and more versatile.

At MEDILAB, we supply a complete range of high-quality adapters manufactured from Borosilicate 3.3 glass and premium-grade plastics, ideal for distributors, importers, and bulk buyers worldwide. Our products are engineered for durability, chemical resistance, and long-term reliability in professional laboratory environments.

Types of  Glass Adapters We Supply

1. Delivery Adapters (SKU: 11117)

These adapters guide vapours or liquids from condensers into receiving flasks.

  • Ideal for distillation setups
  • The curved design ensures smooth downward flow
  • Prevents splashing and contamination

Perfect for general chemistry, organic synthesis, and teaching labs.

2. Receiver Adapters – Straight (SKU: 11118)

A straight connector is used to transfer condensed liquid directly into receiving vessels.

  • Standard ground glass joints
  • Fits perfectly in vertical distillation setups
  • Ensures controlled, drip-free collection

Commonly used where simple, direct connections are required.

3. Receiver Adapters – Bend with Vent (SKU: 11119)

A bent adapter with an additional vent tube for pressure release.

  • Maintains smooth flow of distillate
  • Prevents vacuum formation or backflow
  • Useful for reactions that generate gas or pressure

Ideal for sensitive distillations where pressure must stay balanced.

4. Receiver Adapter – Straight with Vacuum Connection (SKU: 11120)

Designed for operations involving vacuum support.

  • Built-in hose connector
  • Creates airtight setups for vacuum distillation or filtration
  • Straight design for compact assembly

Frequently used in organic chemistry, extraction, and purification labs.

5. Receiver Adapter – Bend with Vacuum Connection (SKU: 11121)

A bent version that allows easy tubing connection while maintaining a smooth flow path.

  • Excellent for angled setups
  • Ensures safe vacuum operation
  • Reduces strain on hoses and joints

Popular in laboratories running continuous distillation or evaporative processes.

6. Receiver Adapters – Inclined (SKU: 11122)

A T-shaped, angled adapter used to divert flow in specific directions.

  • Ideal for multi-stage setups
  • Helps maintain ergonomics in complex assemblies
  • Strong and stable for repeated use

Often used in fraction collectors and specialized distillation arrangements.

To ensure long service life and safe use:

  • Align joints properly before inserting—never twist or push forcefully.
  • Use joint clips or clamps to secure heavy assemblies.
  • Apply joint grease only when required for airtight sealing.
  • Hold the adapter close to the joint when connecting or disconnecting to avoid strain.
  • Avoid exposing the glass directly to flame unless the design allows for heating.

Precautions

  • Do not subject the adapter to sudden temperature changes to avoid thermal shock.
  • Inspect for chips or cracks before use—replace immediately if damaged.
  • Ensure proper joint size matching to avoid leakage or accidental disconnection.
  • Clean thoroughly after each use to prevent contamination or chemical buildup.
  • Avoid overtightening hoses on receivers with vacuum or vent connections.
