How many speed-controlled pumps do the DASbox Mini Bioreactors feature?

The DASbox Mini Bioreactor System provides two integrated peristaltic speed-controlled pumps per vessel as standard. Two extra feed lines per bioreactor can be added using a DASGIP MP8 multi pump module. Each peristaltic pump can be operated independently.

How are DASGIP vessels agitated?

DASGIP bioreactors feature powerful overhead drives with agitation speeds ranging 30 – 1,600 rpm. The DASGIP TC4SC4 controls temperature and agitation in up to four bioreactors. Users can individually define each outlet set-point as well as choose from different operation modes (e.g. continuous or interval agitation).

Do stainless steel components bear any risk of corrosion?

As it is highly resistant to most laboratory chemicals, stainless steel, e.g. 1.4571 (AISI-316Ti), 1.4404 (AISI-316L), is used for wetted parts in DASGIP Bioreactor Systems. A passive coating made of chrome oxide protects the steel from oxidizing agents. Despite these protective properties, corrosion can still occur in extreme situations such as mechanical surface damage or when the parts come in contact with concentrated acids or alkaline solutions. An indication of corrosion can be discoloration that is visible even after a thorough cleaning (ultrasonic bath with an approved stainless steel cleaning solution).
