Process Analytics
Our process analytics solutions, featuring Variable Pathlength Spectroscopy for at-line and in-line concentration monitoring systems, ensure that products meet required Process Analytical Technology (PAT) standards. These tools provide critical data for optimizing bioprocesses and ensuring compliance with regulatory requirements.
MAVEN gives you optimized, automated, don’t-even-sweat-it control of glucose and lactate concentrations in cell culture and fermentation. Suddenly, you’re the boss of your bioreactor.
Keep Your Cells Happy with Accurate Analyte Concentrations
Fluctuations in glucose levels, associated with infrequent measurements and bolus feeding, may cause metabolic deregulation and undesirable process deviations.
That’s where MAVEN comes in. It has your back, automatically monitoring and controlling glucose and lactate concentrations, helping you realize your PAT strategy.
Precise & Sterile Measurement Using Diffusion Sampling Technology
MAVEN’s measurement cell connects to a diffusion probe installed in your bioreactor via a pre-configured tubing set. Only glucose and lactate molecules are small enough to diffuse through the semipermeable membrane into the buffer fluid, meaning there is no loss of bioreactor volume and no increased risk of process contamination.
Step 1:
Small amount of clean buffer solution is delivered from the buffer bag into the diffusion probe
Step 2:
Buffer flow is paused and analyte molecules diffuse through the membrane into the buffer fluid
Step 3:
Flow is resumed, the loaded buffer is delivered to the measuring cell
Step 4:
Analyte concentrations are measured by the biosensor, and the used buffer is disposed of into the waste container
Automated Control of Glucose and Lactate for Optimal Productivity
MAVEN answers the urgent need for on-line measurements and automated control of glucose and lactate levels, which reduces manual labor, lowers risk of contamination from sampling, decreases risk of human error with feeding, and reduces the stress that cells may experience from variable glucose and lactate levels. Ultimately, MAVEN helps ensure optimal productivity and consistent product quality.

MAVEN Loves to Collaborate with Your Bioreactors and Fermenters
Reusable autoclavable and single-use probes and flow cells make MAVEN compatible with most types and sizes of bioreactors and fermenters.
Improve process understanding and develop process control and feeding strategies in the lab and use the same PAT technology to achieve a more robust process control in clinical and commercial manufacturing. With MAVEN, you can develop and refine your process control strategies, ensuring optimal performance and scalability of your bioprocess.

How Will You Use MAVEN?
MAVEN is here to give you control and help you maintain optimal cell culture or fermentation process conditions for laboratory or industrial cultivations of microorganisms and cell cultures.
Biologics
Maintain optimal concentrations of glucose and lactate to maximize yield and product quality.
Cell Therapy
Improve efficacy and safety of CAR-T cell therapies with tight control of glucose.
Fermentation
Precisely control substrate feeding in microbial fermentation processes.
Industrial Biotechnology
Monitor and control production of cultivated meats, beverages, and biofuels.
Resources
Manual sampling always carries a greater risk of process contamination than on-line measurement with sterilized diffusion probes. Reusable probes and flow cells are steam autoclavable and their performance has been demonstrated in GMP applications. A great advantage of the diffusion technology is that it does not consume any media, making closed loop control possible for very small bioreactors.
The compact devices utilize preconfigured single-use tubing sets. The tubing sets connect to a calibration standard for automated recalibration at user-specified times or intervals throughout the duration of the batch. The only components that require sterilization are the reusable diffusion probes and flow cells. Single-use probes and flow cells are also available and can be pre-sterilized.
On-board PID and On/Off controllers enable direct feedback control of substrate feeds. External pumps can be directly connected via the digital or analog outputs. Alternatively, if a SCADA system or dedicated bioreactor controller is available, the measurement results can be instantly transferred over analog (0-10V or 4-20 mA) or digital (Modbus TCP or OPC UA) signals.
MAVEN products and support are available for purchase directly from 908 Devices in North America and Europe and through a network of distributors.
At this time, each bioreactor or fermenter would need a dedicated MAVEN device.
Bulk transport buffer solution cannot ingress into the process medium. However, a small number of salt ions from the buffer solution may cross the membrane barrier but would not have any undesirable effects on cells or micro-organisms.
