Choose the opening before the nominal volume

Fit a small pipette or dropper with a blue silicone bulb selected by bulb volume and opening diameter.

Choose the opening before the nominal volume

HS20629A is the 1 mL format with a 6 mm hole; HS20629B is the 3 mL format with a 6.5 mm hole. Compare the pipette or dropper end with the opening before choosing. The bulb volume identifies the model; it is not a statement of calibrated delivery accuracy or of a fixed number of drops.

Compare the two hand-held profiles

The smaller bulb is 1.1 × 0.47 inches (28.7 × 12 mm), while the larger is 1.6 × 0.70 inches (41 × 17.8 mm). Both use blue silicone rubber and are intended for Pasteur pipettes, small pipettes and medicine droppers. The photographs show the bulb shape and collar; the ordering rows identify which volume and opening you receive.

Order replacement bulbs, not a complete dropper

Each SKU is supplied as a pack of 24 bulbs. Pipettes, glass dropper tubes and collection vessels are separate workflow items. For controlled volumetric delivery, select an appropriate calibrated pipette and controller rather than expecting an ungraduated bulb to set a measurement.

Choose the exact catalog number

Compare the configuration and order unit in the ordering table. The listed pack belongs to one selected catalog number; a family photograph is not an assorted kit unless that row explicitly says assorted.
