CERTUS FLEX Micro Dispenser

Microdispensing at its best. Flexibility to use the solvents you need, across an ideal range of dispensing volumes, at speeds that keep your laboratory flowing.


The Certus FLEX is a modular system in two basic versions, with 5 or 8 individually controllable channels. These channels can be equipped with different valves to facilitate ideal dispensing of substances with different physical properties. The Certus FLEX has been developed for contactless dispensing of a broad range of liquid substances and large molecules, using Gyger's renowned microvalve technology and air pressure control, giving you maximum precision and flexibility.

FLEX 8 valves

Unique microvalves for more dispensing operations, with less dead volumes

Over 500 million cycles without losing accuracy

The Certus FLEX delivers volumes in single doses, in contrast to many other techniques, allowing you to have the fastest delivery and the longest valve life. With an assortment of valve sizes, you can dispense a wide range of fluid types.

Flexible fluid uptake options to meet your exact needs

FLEX side view

Fluids can be supplied to the dispenser from bottles and tubes for bulk dispensing, or from syringes to achieve the lowest dead volumes. This allows you to more effectively dispense smaller volumes and high value substances from luer-lock syringes (from 3 - 60mL).

Liquids. Large molecules. High and low viscosity

The channels can be equipped with different valves in order to facilitate an ideal dispensing of substances of different physical properties.
