Testing performed by our in-house service team:

The Biostat B/RM 50 Rocker System passed all tests and was found to be fully functional:

- We verified the power and communication to the system.
- We tested the operation of the touchscreen display.
- We checked the functionality of all peristaltic pumps.
- We inspected all gas tubing connections for secure fitment and leaks.
- We tested the accuracy and uniformity of temperature control.
- We evaluated the bag rocking mechanism for consistent motion.
- We tested alarm and safety interlock functionality.
- We tested pH and o2 sensor output functionality.
- We tested the load cell on the rocker mechanism.

Instrument Overview:

- The Sartorius Stedim Biostat B is a benchtop bioreactor controller for flexible cell culture conditions.
- It supports single-use bag systems and integrates with the RM 50 rocker for gentle mixing.
- The Biostat B allows control of key parameters like pH, DO, and temperature.
- Biostat RM 50 Rocker accommodates 1–50 L bags with adjustable rocking angles and speeds.

WHY DO CUSTOMERS MAKING CRITICAL LAB PURCHASES CHOOSE TO ORDER WAVE BIOREACTORS FROM US?

They want to ensure the controller has been fully tested with live feedback from the rocker, verifying PID control accuracy across temperature, pH, and dissolved oxygen loops.

They want to confirm that the rocker platform delivers correct agitation angles and speeds, tested under simulated load to identify mechanical asymmetry, drift, or motor lag that can disrupt shear-sensitive cultures.

They want assurance that the rocker motion controller executes full-duty cycles without servo skipping, vibration anomalies, or uncontrolled ramp acceleration, common failure points in poorly serviced systems.

They want to ensure pH and DO channels have been calibrated using two-point measurements that verify the supplied probe inputs are capable of adjusting to replacement probes.

They want to confirm that electronic noise and EMI levels at the detector/amplifier stage remain within tolerance and will not distort signal fidelity.

They want to ensure that all pump heads (Ex, base/acid/antifoam/feed) are functional, calibratable, and cycle-tested, preventing dosage drift or reagent starvation during long perfusion runs.

They want to ensure the controller has been tested through full-simulation runs with live signal feedback from sensors, not just idle boot checks.

They want peace of mind, knowing their instrument is backed by a warranty from a company that can stand behind it.
