The units are offered as used equipment. Six units are available.
Sartorius Stedim BIOSTAT CultiBag RM 50 is a rocking motion single-use bioreactor platform for low-shear cell culture and bioprocessing. The system uses wave-mixed rocking motion with disposable CultiBag RM bags.
Six used units are available. Single-use CultiBag RM bags are supplied to the first buyers.
The 50 L CultiBag RM format has a 25 L maximum working volume. This separates the disposable bag’s nominal format from the usable culture volume for cell culture and seed train planning.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
