Description
Flexsafe® RM 20 L optical ViaMass single-use bioreactor bags are built for cell cultivation on Biostat® RM rocking-motion systems where low shear stress and integrated optical monitoring are required. Optical bags feature single-use opto-chemical pH and dissolved oxygen (DO) sensors that are already pre-calibrated, enabling continuous process control. Together with the Biostat® RM control tower they support high-end cultivation with full process automation across rocking-motion workflows. The bags fit Biostat® RM bioreactors and belong to the Flexsafe® RM single-use portfolio from manufacturer Sartorius, available in sizes from 2 L to 200 L. Rocking-motion mixing promotes homogeneous culture conditions while limiting mechanical stress on cells. In this optical ViaMass configuration the 20 L bag is supplied for applications that specify the ViaMass option alongside optical pH and DO sensing. Bags up to 50 L in the line may also use a 38 mm screw cap for adding or removing larger objects such as microcarriers in a laminar flow cabinet. This pack contains 5 pieces for single-use bioprocess and cell-culture work.
This article is part of Cell culture accessories, in Cell culture.

Questions about Flexsafe® RM 20L opt ViaMass (5 pcs)
What is this article?
Flexsafe® RM 20L opt ViaMass (5 pcs) is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Cell culture accessories, inside Cell culture, in Microbiology lab supplies.
Cell-culture accessories are the pipettes, the filters and the small tools that stay sterile around a cabinet: aspirators, tube caps, rack inserts. The point is sterility and a material that does not leach into the medium. A non-sterile version of the same shape is a different article.
Cell culture grows cells outside the body. The medium, often with serum, supplies what the flask does not. A flask or a dish is the vessel, treated so the cells attach or left untreated so they float. Contamination by microbes, or by another cell line, is the ordinary failure. Cold-chain articles in this work, including serum, are never part of free standard delivery. Lines are catalogued by ATCC. Papers are on PubMed. Practice is summarised by the WHO laboratory biosafety topic.
Which category should I open next?
The category is Cell culture. The sub-category is Cell culture accessories. The catalogue is Microbiology lab supplies.
Shelves beside this one are Cell culture media & sera, Cell culture flasks, Cell culture plates & dishes and Cell strainers, inserts & scrapers.
What should I check before I order?
