The Variable Speed Pump is the Plug&Play module you need to carry out substrate additions (i.e. for Fed-batch and semi-continuous processes) or withdrawal/harvesting actions according to a number of feeding/bleeding profiles.

The bVSP gathers hardware and software capabilities for the addition of substrates to the bioreactor in a precise, versatile and analysable way

features and accesories

Adaptable to a variety of bioprocess particularities

The VSP is available in a wide range of head and speed formats, which renders it adaptable to a variety of bioprocess contexts and needs (e.g. large biomass size, high viscosities, etc).

Its Plug&Play design allows for an immediate usage upon purchase

The bVSP includes everything for its direct connection to a compatible bioreactor and the subsequent recognition and automatic upgrade of Bionet’s software capabilities.


The bVSP software module enhances further data and process control possibilities

The bVSP software offers different pump control strategies:

•Direct configuration of constant, lineal and exponential feeding profiles (non feedback automation)

•Establishment of a control loop that relate flow rates with turbidity-, weight-, or other PATs- measurements when these are present (feedback automation).

•Establishment of a control loop that relates the bVSP functioning with the DO value, within the DO cascade-mode control (feedback automation).

•Activation of flow rate upon the occurrence of an event (time or measurement) configured as a recipe transition.

The bVSP software module also activates data registration and visualization features.

•Online visualization of flow measurements by the pump in the summary tables as well as trend and comparative graphs

•Data registration (in csv format).


The bVSP, in turn, can be further expanded with extras to enhance precision, or to enable further data and control possibilities… Find more about these options…


The bScale Module is comprised of a connectivity module designed to recognize most of the scales in lab and production settings, and the scale(s) themselves.

It expands the bioreactor weight control functions, by providing visualization and registration of weight measurements data as well as by providing feedback control of the addition and/or withdrawal pumps if present.

OD Sensor

The OD sensor is recognized by the software to allow for turbidity measurement data to be visualized real-time, registered and to expand the bioreactor automation possibilities.
