The Techne Model MCS-104L 4 Postion Biological Stirrer is designed for optimal suspension cell culture and the use of microcarriers. It can accommodate up to four culture vessels and features a speed range of 0 to 80rpm, softstart/stop for slow acceleration and deceleration, interval setting option, a stainless steel stirrer platform with locators for the culture vessels, and is designed for incubator environments up to 40°C with 95% humidity.

The culture vessels incorporate a unique base design which, together with the bulb-ended stirrer, ensures that the cells are lifted into suspension at the lowest possible speeds. This gentle stirring action promotes high cell yields by preventing cell shearing.

Cell attachment to microcarriers and high cell yields are ensured by the special softstart/stop design and interval stirring option. The former ensures slow acceleration and deceleration of the stirrer, avoiding excessive turbulence in the culture media and eliminating cell damage. The interval stirring can be used during the attachment phase to further reduce agitation of the media or when culturing particularly fragile cells.

The stirrers create virtually no heat so there is negligible heat transfer from the magnetic drive to the culture vessel, making the system suitable for use in both incubators and cold rooms.
