ID Rocker

Rocking and Instrumented T-Flasks are Better Flasks. Combine closed-loop, gentle tissue culture flask agitation from real-time optical sensor data for better cell culture outcomes.

Gentle agitation of tissue culture flasks has been shown to improve cell outcomes. Vallejos et al. (2012) showed that cells grew faster, had higher viable cell density, and produced less lactate with rocking compared to static cultures.

The ID · Rocker combines adjustable T-flask rocking with real-time, non-invasive monitoring of pH and dissolved oxygen (DO). An interface box allows for closed loop control of rocking speed with feedback from the sensor measurements so that your cells can reach target DO levels.

Place the compact ID · Rocker in your cell culture incubator
and elevate your static T-flask cultures.

How do I incorporate optical sensors in my T-flasks?

The ID • Rocker monitors pH and dissolved oxygen and controls rocking speed to help you reach your experimental design parameters.

  • ID • Sensors pH and ID • Sensors DO are securely attached to the T-flasks.
  • Four ID • Readers are embedded into the laboratory shaker platform. T-flasks with ID · Sensors are placed on top of ID • Readers and secured on the rocking platform.
  • ID • Data Hub software loaded onto your laptop collects pH and DO data through the ID • Converter for each of the tissue culture flasks.
