Adapter, Cone Screw Thread, Simple Glands

[table id=598 /]

The GISCOM Adapter, Cone Screw Thread, Simple Glands is a precision glass connector designed for secure attachment of shafts, probes, or tubing to standard ground-joint glassware. It ensures a tight, leak-proof seal using a screw-thread gland assembly, making it essential for laboratory setups requiring stable mechanical connections. This adapter improves workflow safety, prevents air or liquid leakage, and supports efficient integration of rotating or stationary components in various chemical, analytical, and research applications.

Key Features

• Secure cone screw-thread design for reliable sealing of 6 mm diameter shafts or probes.
• Supplied with a high-quality screw cap for fast tightening and easy handling.
• Chemically resistant materials suitable for aggressive reagents and solvents.
• Smooth, accurately ground joint ensures excellent compatibility with standard glassware.
• Provides a strong mechanical hold without the need for additional sealing materials.
• Durable construction is ideal for repeated heating and cooling cycles.
• Clear, high-transparency glass allows visual monitoring of connections.

 Material Specifications

• Material: Premium Borosilicate Glass 3.3
• Thermal Properties: Low thermal expansion (3.3 × 10⁻⁶ /°C), Excellent resistance to thermal shock Suitable for autoclaving and high-temperature operations
• Chemical Properties: Highly resistant to acids, alkalis, solvents, and corrosive vapours. Ensures non-contaminating, inert interaction with samples
• Mechanical Properties: Scratch-resistant, durable glass body. Precision-ground joint for high sealing integrity
• Standards:  Joint dimensions follow international interchangeability standards

Technical Specifications

• Thread Type: Cone screw-thread gland connection
• Cap Compatibility: Supplied with screw cap to fit 6 mm diameter shafts
• Joint Sizes: As per the standard size table
• Tolerance: Precision-ground joints for a tight, leak-free fit. Not a calibrated measuring device
• Accessories Included: Screw cap (gland), glass adapter body

Handling & Precautions

• Avoid overtightening the screw cap to protect the glass thread.
• Always insert shafts gently to prevent stress on the joint.
• Clean with mild laboratory detergents; avoid abrasive cleaners.
• Autoclave only with gradual heating and cooling to prevent thermal shock.
• Inspect routinely for chips or cracks, and discontinue use if damage is found.
• Use only compatible-sized shafts to maintain sealing performance.

 Applications

• Ideal for research laboratories, chemical industries, pharmaceuticals, QC/QA labs, and academic institutions.
• Used for securely connecting thermometers, stirrer shafts, probes, sensors, or tubing to reaction systems.
• Ensures airtight and liquid-tight operation in distillation setups, reaction assemblies, and analytical instrumentation.
• Enhances workflow safety by preventing accidental leaks when introducing rotating or stationary equipment.
