Graduation:
Our graduated pipettes are available with amber stain (standard) or blue graduation:
- the amber stain graduation penetrates into the glass surface and is, therefore, more resistant than the blue, fused-on enamel graduation
- the blue graduation is fused on the glass and resistant against most acid and alkaline solutions
On request Marienfeld Superior graduated pipettes are also offered with Schellbach stripe. This stripe at the back of the instrument facilitates reading precisely the meniscus of a liquid.
- made of soda lime glass
- low risk of breakage

Furthermore, it can extend the waiting time and thereby influence the accuracy of the measuring.
