 Pipette Bulbs are high-quality rubber suction devices designed for safe, controlled filling and dispensing of liquids through laboratory pipettes. They provide an efficient, hands-free alternative to mouth pipetting, ensuring user safety and preventing contamination. These bulbs are essential for accurate liquid handling in analytical, research, and industrial environments.

Key Features

• Safe, Hands-Free Operation: Eliminates the risk of mouth pipetting and exposure to hazardous or corrosive chemicals.
• High Elasticity & Grip: Ensures secure handling and consistent pressure for precise suction and dispensing.
• Chemical & Temperature Resistant: Suitable for a broad range of laboratory reagents and working conditions.
• Durable Construction: Tear-resistant and long-lasting—ideal for high-use laboratory workflows.
• Universal Fit: Compatible with most standard glass and plastic pipettes.
• Comfortable Design: Soft rubber texture for easy compression and fatigue-free use.

Material Specifications

Material Options:

• Natural Rubber: Excellent elasticity, strong grip, high mechanical strength.
• Silicone Rubber: Superior chemical resistance, high-temperature tolerance, and long service life.

Properties:

• Thermal Resistance: Silicone: Typically up to +200°C; Natural Rubber: Typically up to +70°C
• Chemical Resistance: Good resistance to water-based solutions, mild chemicals, and commonly used laboratory reagents.
• Mechanical Properties: Flexible, crack-resistant, high tear strength.

Standards Compliance:
Manufactured in accordance with accepted international laboratory consumable standards (ISO/DIN guidelines for general labware; material properties aligned with ASTM rubber specifications).

 Technical Specifications

• Available Sizes: Small, Medium, Large, and Special Shapes (standard pipette compatibility).
• Capacities: Suitable for pipettes from 1 mL to 50 mL.
• Dimensions: Size-dependent (custom sizing available on request).
• Accuracy & Control: Designed for controlled suction and precise liquid release through finger pressure.
• Compatibility: Works with volumetric, serological, graduated, and Pasteur pipettes.
• Accessories: Optional pipette adapters (if required by the user).

Handling & Precautions

• Safe Use: Compress the bulb before attaching to the pipette; release gently for controlled aspiration.
• Cleaning: Wash with mild detergent and rinse with distilled water.
• Sterilisation: Silicone bulbs: Autoclavable at standard laboratory conditions. Natural rubber bulbs: Not recommended for high-temperature autoclaving; disinfect using non-aggressive chemical solutions.
• Dos: Store in a cool, dry environment. Inspect regularly for cracks or wear.
• Don’ts: Avoid exposure to concentrated solvents or oils that may degrade rubber. Do not force onto oversized pipettes.

 Applications

• Research Laboratories: Routine liquid transfers, analytical experiments.
• Pharmaceutical & Biotech: Sample preparation, reagent handling, QC/QA testing.
• Chemical & Industrial Labs: Safe handling of corrosive and toxic samples.
• Academic Institutions: Standard teaching and training workflows.
• Healthcare & Diagnostic Labs: Controlled pipetting in microbiology and clinical chemistry.

Pipette bulbs play a central role in ensuring safety, accuracy, and efficiency in everyday laboratory operations—making them indispensable across scientific, educational, and industrial environments.
