BRAND seripettor ® pro bottle-top dispenser (2.5–25 ml) 4720450

The versatile powerhouse for laboratories and chemistry

The BRAND seripettor ® pro (2.5–25 ml) significantly expands the range of applications of the classic seripettor ®. Thanks to the use of higher-quality materials in the flow path, this model is ideal for dispensing volumes of up to 25 ml of demanding chemicals. It handles diluted to medium-concentration acids, various salt solutions, polar solvents and even essential oils with ease – tasks for which standard equipment often falls short.

Efficiency through automatic stroke

For rapid batch analyses, the seripettor ® pro is equipped with an integrated return spring. This automatically pushes the piston upwards after each dispensing stroke and refills the cylinder automatically. This ensures smooth, fatigue-free operation without the need for manual reloading. Volume adjustment is carried out reliably and precisely via a mechanical rack and pinion system.

High-quality materials for broad compatibility

Unlike the standard version, the seripettor ® pro utilises materials such as borosilicate glass, ceramic (Al₂O₃), PFA, ETFE, FEP and PTFE. This makes it the perfect tool for:

• Acids: e.g. HCl, H₂SO₄, HNO₃ (observe concentration limits).

• Solvents: Polar solvents such as acetone, ethanol or methanol.

• Special media: UV-sensitive reagents, essential oils and crystallising media.

Cost-effective and low-maintenance

Cost-effectiveness is also a key focus of the Pro version: the entire dosing unit can be replaced by the user themselves, without tools and at low cost, in the event of wear or contamination. This minimises downtime and repair costs in day-to-day laboratory work.
