Product Description

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 of 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.

Replaceable Dispensing Cartridge:
Quick-change cartridge makes service a breeze and keeps life-time service costs low. If wiping seals wear out, or are damaged by crystallizing reagents, just change the inexpensive cartridge, and you're back in business!

Protects Light-Sensitive Reagents: Pump assembly with corrosion resistant spring. An opaque upper sleeve helps protect liquid from UV-light during dispensing operations, while permitting observation of cylinder to confirm purging of bubbles.

Wide Chemical Range: Valves and seals on the seripettor pro allow a broader range of liquids to be dispensed than the regular seripettor.

Telescoping Filling Tube: Adjusts to fit many bottles without cutting.

Threaded Safety Cap: Attaches and removes with a quick twist.

Spring-Loaded Piston: Permits one-handed, semi-automatic operation.
