Bottletop dispenser, BRAND Seripettor Pro, 0.2-2mL

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 Hastalloy stainless steel 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
