ZORO SELECT Grade B Measuring Pipette
This ZORO SELECT measuring pipette is a Grade B glass instrument calibrated to deliver 1 mL volumes with 0.01 mL graduation subdivisions. It is intended for laboratory personnel who require Class B tolerance volumetric measurement in routine analytical or quality-control workflows. The package supplies twelve pipettes for batch use or stock replenishment.
330 mm glass construction with yellow band
Each pipette is manufactured from glass and measures 330 mm in length, identified by a yellow band that denotes its Class B rating. The single-mark design with 0.01 mL subdivisions allows direct reading without negative graduations, while the glass body provides chemical resistance compatible with standard laboratory solvents and reagents. A tolerance of 0.015 mL applies across the 1 mL capacity.
Verify Class B tolerance and chemical compatibility
Before ordering, confirm that the 0.015 mL tolerance meets your method validation requirements for volumetric accuracy. Ensure the glass material is suitable for the specific chemicals and temperature ranges used in your procedures. Note the product carries a California Proposition 65 warning for substances identified as causing cancer and reproductive harm, which may affect handling protocols or disposal requirements in your facility.

Questions about this item
What graduation subdivisions does the Grade B glass pipette use?
The pipette is graduated in 0.01 mL subdivisions with a tolerance of 0.015 mL per the Class B standard.
What physical dimensions should I allow for the 330 mm pipettes in a rack or drawer?
Each pipette measures 330 mm in length, so storage must accommodate that full span plus clearance for the yellow band.
How should I clean the glass pipettes before first use to avoid the Proposition 65 warning?
Rinse thoroughly with detergent and distilled water, then autoclave or heat-dry; the warning covers trace substances in the glass, not surface residue.
