Description

Rubber Bellow with Cotton Net is a precision-engineered suction device designed for use with automatic burettes, offering smooth, controlled liquid delivery in analytical procedures. Its reinforced cotton-net covering enhances durability and prevents deformation under repeated compression. The below is ideal for laboratories requiring consistent performance, safety, and long service life in routine titrimetric operations.

Key Features

• Optimized for Automatic Burettes: Ensures stable flow and accurate reagent dispensing.
• Reinforced Cotton Net Design: Protects the bellow from stretching, tearing, or accidental expansion during heavy use.
• Enhanced Finger Grip: Net covering improves handling, even with wet or gloved hands.
• Chemical-Resistant Construction: Suitable for common titration reagents and acidic/alkaline solutions.
• Durable & Long-Lasting: Excellent elasticity and fatigue resistance for extended laboratory use.
• User-Friendly Operation: Smooth compression and rebound for precise control of liquid flow.
