This is a cost-effective solution to register the presence of fluids inside clear tubing. The sensor is able to trigger a signal to another instrument and act accordingly in many ways: stop the flow, wait a certain amount of time, allow enough flow to clear the tubing or reset the sensor.It is an easy way to stop an experiment if a bubble appears or to correlate flow rate behavior with bubbles that could appear during an experiment.
Available for 1/16" OD (Small) or 1/8" OD (Large) clear tubing.
General
The microfluidic bubble detector comes in two different housings suited to the use with 1/16″ or 1/4″ outside diameter (OD) tubes. It can be plugged directly into the Elveflow OB1 pressure controller, or it can be used as a standalone unit with the Elveflow Sensor Reader and another instrument able to read voltage signals.
The Bubble Detector cannot be directly connected to a computer! The Bubble Detector can work in digital mode only and it needs to be connected to the Sensor Reader. The Sensor Reader is sold separately and can manage up to 4 different sensors at the same time. Thanks to the integrated software you will able to record, store and analyze the data gathered by the sensor directly on your computer.
Features & Benefits
- Reliable non invasive technique
- Cost effective compared to camera check
- Based on true/false logic
- Large compatibility: wide range of tubing size
- Software average functions
- Use anywhere in your setup
- Prevents damage in cells with bubble bursts
- Setup automation (possibility to use if conditions)
Applications
Bubbles are a big challenge to address in microfluidics, as they can induce flow modifications or interact with the experiment and cause damages to the sample. One can monitor the formation of microfluidic bubbles (change of the working fluid) at any given point of his setup and automate the experiment accordingly (increase the pressure or switching valves to direct the bubble in another fluidic path for instance).
- Bubble detection
- Liquid level sensing
- Blood processing equipment
- Patent connected medical devices
- Perform bilateral recirculation based on air detection
Principle
How the detection works: changing in the medium flowing (bubbles for instance) causes variations (diffraction and absorption) of the light path of the detector.
A LED creates a light beam at known power. This emitted light crosses the capillary and the fluid passing through. It is then collected by an NPN silicon phototransistor. This phototransistor converts the light power into an electrical power.
When a fluid changes, the optical index and the light absorption coefficient change accordingly. It induces a change in the electrical power and allows to detect changes in the fluid.
