Gas Bulb

The GISCOM Gas Bulb is a high-quality plastic bulb designed for controlled gas transfer, dispensing, and flow regulation in laboratory systems. It enables users to increase or decrease gas volume through manual squeezing, allowing highly accurate and repeatable gas manipulation. Essential for analytical, educational, and research workflows, the gas bulb ensures safe, contamination-free handling of gases across scientific and industrial environments.

Key Features

• Consistent, controlled gas delivery via a manual squeeze-and-release mechanism
• Chemical-resistant polypropylene construction for long-term laboratory use
• Leak-proof integrated valves ensure safe and precise gas flow control
• Lightweight, ergonomic, and easy to operate with one hand
• Durable construction suitable for repeated laboratory operations
• Non-reactive internal surfaces to maintain sample integrity
• Cost-effective, reusable, and low-maintenance design
• Compatible with standard laboratory tubing

Material Specifications

Handling & Precautions

• Ensure valves are securely attached to tubing before operation
• Avoid exposure to high-temperature dry heat; only wet autoclave within PP-safe limits
• Rinse with mild laboratory detergents; avoid strong oxidising solvents
• Do not overcompress the bulb to prevent deformation or fatigue
• Store in a dry, clean environment away from direct sunlight
• Replace bulb if signs of wear, cracking, or valve looseness are observed

Applications

• Controlled gas transfer in chemical, biological, and analytical laboratories
• Air displacement, gas sampling, and purging operations in pharmaceutical and biotech facilities
• Daily teaching and demonstration use in universities and academic labs
• Quality control and process testing in QC/QA labs
• Suitable for general laboratory setups requiring simple and reliable gas management
