Volumetric pipettes are essential laboratory tools designed for precisely measuring and transferring specific liquid volumes. These pipettes are calibrated to Class A tolerances per ASTM E-542 and ASTM E-969 standards, ensuring high accuracy and reliability.
Material: Made from high-grade borosilicate glass, volumetric pipettes are durable and resistant to thermal shock and chemical corrosion, which enhances their longevity and reliability in various laboratory settings.
Calibration: Each pipette is individually serialized and comes with a Certificate of Identification and Capacity, traceable to NIST standards. They are tested and calibrated in ISO/IEC 17025 certified laboratories, ensuring precision in measurements (Corning, Fisher Scientific).
Capacity and Size: Available in various sizes, including 1 mL, 2 mL, 5 mL, 10 mL, 20 mL, 25 mL, 50 mL, and 100 mL, allowing for flexibility in different experimental setups. The accuracy tolerances for these pipettes meet or exceed the stringent requirements for Class A volumetric ware (Sargent Welch).
Design: Volumetric pipettes feature a single graduation mark, ensuring the pipette delivers the exact volume it is calibrated for. They are color-coded for easy identification and have enamel graduations for long-lasting readability (VWR, Corning).
Usage: These pipettes are designed to contain (TC) or deliver (TD) specific volumes of liquid, making them ideal for quantitative analysis in chemical, biological, and clinical laboratories. They are reusable, which makes them cost-effective over time (Sargent Welch).
