Volumetric Pipette (One Mark): Precision Transfer Pipette
High-accuracy Borosilicate glass transfer pipettes calibrated for precise liquid volume delivery.
Engineered for Exact Volumetric Delivery
The Volumetric Pipette (One Mark), also known as a Transfer Pipette, is a staple in analytical chemistry. It is designed to deliver a single, fixed volume of liquid with extremely high precision. Our pipettes are manufactured from low-expansion Borosilicate 3.3 glass, ensuring excellent chemical resistance and thermal stability.
Each pipette features a permanent "One Mark" graduation line, calibrated to deliver (TD, Ex) the specified volume at a reference temperature of $20^{\circ}C$. These are ideal for preparing standard solutions and performing accurate titrations.
Key Technical Features
- Premium Borosilicate 3.3 Glass: Offers superior resistance to acids, alkalis, and thermal shock.
- Precision Calibration: Individually calibrated to meet international standards (ISO/DIN) for Class A or Class B accuracy.
- Color-Coded Markings: Includes standardized color coding for easy identification of capacities in a busy lab environment.
- Optimized Tip Design: Features a smooth, tapered tip for controlled flow and minimal liquid retention.
- Durable Enamel Printing: High-contrast markings that resist fading even after repeated autoclaving or chemical cleaning.
