Glass pipette
Introduction to Glass pipettes
Glass pipettes are measuring tools for accurately aspirating and transferring liquid volumes, widely used in laboratory analytical procedures and sample preparation. Depending on operational requirements, users can choose straight pipettes (graduated pipettes) for flexible volume dispensing or volumetric pipettes (bulb pipettes) to transfer fixed solution volumes.
When purchasing glass pipettes, technical criteria to consider include Class A or Class AS accuracy, construction from borosilicate 3.3 or soda-lime glass, and blue printed graduations or durable amber graduations. Hoa Viet currently distributes glass pipettes from Assistent, Duran, Hirschmann, and Kimble-DWK, complying with technical standards such as DIN EN ISO 835 or DIN EN ISO 3819 with batch certificates or conformity certificates according to inspection needs.
What is the difference between measuring pipettes and volumetric pipettes?
Straight pipettes feature graduation marks along the tube body, allowing flexible aspiration of various volume levels. Bulb pipettes feature a wide bulb section with 1 or 2 graduation marks, specifically designed to draw a precise fixed volume.
What does Class AS accuracy on glass pipettes indicate?
The Class A designation indicates high volumetric accuracy according to standards, while "S" signifies swift delivery under standardized times. Class AS instruments usually come with a batch certificate or conformity certificate from the manufacturer.
Which glass pipette brands is Hoa Viet supplying?
Hoa Viet currently distributes genuine glass pipettes from Assistent (Germany), Duran (Germany), Hirschmann (Germany), and Kimble-DWK (USA).
What are the advantages of a straight glass pipette with a piston?
This pipette type integrates a built-in piston plunger on the body, enabling users to aspirate and dispense liquids directly without requiring a rubber bulb. This design offers safer and more convenient sample aspiration control.
