Graduated Pipette (serological)v

Graduated Pipettes (Serological) are high-precision volumetric laboratory glassware designed for the accurate measurement and transfer of liquid samples across scientific and medical fields. Fabricated from premium borosilicate glass, these pipettes feature a uniform bore and a durable structure that offers excellent resistance to chemical corrosion and thermal shock.

Designed as "blow-out" pipettes, these serological models are calibrated to deliver their total rated capacity when the last drop remaining in the tip is blown out into the receiving vessel. The permanent, high-contrast graduation lines extend all the way down to the tip, allowing laboratory professionals to perform serial dilutions and variable volume liquid handling with maximum efficiency.

Key Features

• Manufactured from high-purity borosilicate 3.3 glass for superior chemical inertness and clarity
  
• Calibrated to deliver (TD, "To Deliver") with a blow-out ring indicator at the top stem
  
• Full-length, high-contrast graduation markings using durable fired-on enamel for rapid and accurate volumetric readings
  
• Precision-formed tip engineered for controlled, uniform drop distribution and optimal liquid release
  
• Uniform wall thickness and heavy-duty mouthpieces to reduce the risk of mechanical chipping during filler attachment
• International Standards
• Our serological graduated pipettes are manufactured in strict compliance with globally recognized scientific dimensional and quality parameters, ensuring seamless verification for international export and bidding:

• ISO 835 – Laboratory Glassware – Graduated Pipettes
  
• ASTM E1293 – Standard Specification for Glass Measuring Pipettes
  
• ASTM E438 – Standard Specification for Glasses in Laboratory Apparatus Manufacturing
• Available in multiple standard capacities (e.g., 1ml, 2ml, 5ml, 10ml, 25ml) with options for color-coded bands at the top for rapid volume identification on the lab bench. Custom dimensions, variable graduation intervals, and specialized individual calibration certificates can be provided per bulk commercial requirements.

Applications

Extensively utilized across microbiology, cell culture, clinical pathology laboratories, hematology, pharmaceutical research facilities, and academic institutions for preparing serial dilutions, transferring sterile culture media, and general analytical fluid chemistry.
