Pipettes, Graduated, Serological - Class 'A'

These OMSONS graduated serological pipettes are Class A, with a colour code, and made for analytical work that needs exact volume delivery. They're graduated to deliver from any graduation line down to zero at the jet, with the last drop blown out.

Key Features

• Graduations: Permanent amber stain markings fused into the glass, so they stay legible after repeated autoclaving or contact with cleaning solvents.
• Certification: These typically come with a batch certificate.
• Accuracy: Class A (the highest grade), with much tighter tolerances than Class B.
• Standards: Comply with DIN ISO 835 (with colour code) and IS 4423.
• Material: 3.3 borosilicate glass for chemical durability and heat resistance.
• Calibration: Each pipette is individually calibrated "To Deliver" (Ex) at a reference temperature.
• Design: Serological type (graduated to the tip). These are blow-out pipettes, marked with double etched rings at the top.
