seripettor® pro Bottletop Dispenser

Product and ordering information for the seripettor pro wiping-seal bottletop dispenser for dispensing a wide range of reagents commonly used in biological and chemical laboratories.

Catalog #: N/A Category:


The seripettor® pro is a bottletop dispenser designed to handle a wider range of liquids than the regular seripettor® for customers who do not require all the features of the Dispensette®. Like the regular seripettor®, it features an easily-replaceable wiping seal dispensing cartridge, making it especially suitable for liquids that tend to form crystals. Its pump assembly has a corrosion resistant spring and an opaque upper sleeve to protect reagents from UV-light during dispensing, while allowing for observation of reagent to confirm purging of bubbles. The seripettor® pro mounts on most common reagent bottles with its 45mm thread.

Product No. & Specs

The seripettor® pro bottletop dispenser is supplied with: spare dispensing cartridge, discharge tube, telescoping filling tube, three PP adapters (45/38mm, 45/33mm and 45/S40mm), operating manual, and one-year warranty.
