Borosilicate glass 1000mL spinner flask with dual sidearms and height-adjustable Teflon stirring blades.
The Kontes Cytostir 882911-1000 is a 1000 mL borosilicate glass microcarrier spinner flask engineered for advanced cell culture applications. Featuring two large sidearms with screw cap closures, it enables sterile and convenient sampling during live-cell culture processes. The flask incorporates a domed base design to prevent microcarrier sediment buildup underneath the stirring blades, ensuring homogenized suspension of microcarriers that is critical in bioprocessing and biopharmaceutical production pipelines.
Key technical features include:
This flask is widely used in biotechnology research fields such as gene editing, molecular cloning, and cell line development where controlled agitation and sampling during culture are paramount. The impeller assembly is sold separately, allowing customization for specific stirring requirements, which makes this equipment valuable for biomanufacturing and live-cell imaging setups demanding precise environmental control.
Optimized for researchers and process engineers, the Kontes Cytostir flask supports scalable cell culture experiments critical in bioprocessing and regenerative medicine research.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
