Clarification & Harvest

Clarification steps prepare your bioreactor harvest material for downstream purification by reducing the levels of impurities and particulates. Selecting the right separation technology depends on the properties of your fluid stream, process scale, and downstream processing steps.
Our clarification portfolio has options for every process and encompasses the filters and holders, pretreatment solutions, and hardware & systems you need to achieve efficient, robust, clarification to maximize success of your downstream operations.

Clarification Filter Holders & Systems
Our flexible hardware and systems for disposable depth filters are ideal for clarification at pilot and process scales, featuring the modular Pod device that enables scale-up and scale-down within the same footprint.
Clarification Depth Filters & Pretreatment Solutions
To prepare your cell culture harvest for downstream chromatography and purification, our Millistak+® and Clarisolve® depth filters and flocculation polymers offer upstream process solutions for both primary and secondary clarification. Millistak+® HC and HC Pro can be used as polishing filters at a certain point in the downstream purification process.
