Particle tracking analysis measures the number concentration and particle size of ultrafine bubbles around 100 nm — from low to high concentration, in a short time.
"Fine bubble" and "ultrafine bubble" are registered trademarks of the Fine Bubble Industries Association.
The top model of the BLASE Series. Particle tracking analysis measures ultrafine bubbles in a short time, from a low concentration of around 100,000 (105) to a high concentration of around one billion (109)1.
1 The measurable concentration range depends on water quality.
The challenge
Ultrafine bubbles can be observed with a laser — but how they appear depends on the laser’s output and wavelength.
Change the output or wavelength and the same sample looks different. Comparisons between instruments and conditions become subjective.
The more dilute the sample, the fewer particles enter the field of view. In a narrow field, number concentration does not settle.
Dense samples are usually diluted before measurement. Every added step is another assumption behind the value.
BLASE X captures a wide field and counts particles by tracking them. From low to high concentration, in a short time.
Features
Proprietary image processing and a laser system, combined with particle tracking analysis software.
Each imaged particle is tracked individually to obtain its size and the count. Ultrafine bubble measurement is defined by the Fine Bubble Industries Association (FBIA standard), which reviews measurement procedures and instruments.
From around 100,000 (105) to around one billion (109)1. Wide-field image processing and proprietary control processing measure even dilute samples in a short time.
A system that captures ultrafine bubbles over a wide field in a short time gives stable measurement. Bubbles invisible to the eye can be monitored in real time.

Options
A range of options and consumables is available, and we can propose a configuration for your application.
Measure while the liquid sample flows through. No cell change between samples, and suction by syringe allows repeated measurement of the same sample.
Window plate, cell stand and cell as one set. Prepare several sets and throughput rises for consecutive measurement of multiple specimens.
Quartz cell with platinum deposition. Suppresses reflection from below, reducing unwanted scatter and noise.
The base that holds the cell and window plate.
A transparent plate placed over the cell. The liquid spreads stably at the interface, making the measurement area uniform and repeatable.
From measurement-result PDFs: CSV aggregation of number concentration, side-by-side comparison of different PDFs, and re-plotting of graphs.
For calibrating the BLASE series. Scattering intensity, particle characteristics and number concentration approximate UFB, enabling accurate calibration.
The optical magnification is changed to match the particle quantity, so the field of view can be proposed to suit your needs.

Design through manufacture completed domestically. We are happy to advise on operation after installation.
Developed by Schwalbel, which handles control design, mechanical design and software development in-house.
Process
Start with a conversation. Our specialists advise free of charge.
Contact us via the form or by telephone (+81 3-6304-0333). Our specialists advise free of charge.
We discuss your objective, application and schedule and, where appropriate, carry out a preliminary study to determine whether the measurement you need is feasible.
We submit a requirements definition document and a quotation based on your needs.
The equipment is delivered and functionally evaluated in your presence, concluding with acceptance.
A preliminary study requires several evaluation samples, and may incur a separate charge depending on its scope.
FAQ
The measurement method differs. BLASE uses particle analysis software to measure low concentrations in a short time, and high concentrations after dilution. BLASE X uses particle tracking analysis (PTA) to measure from low to high concentration in a short time.
From around 100,000 (105) to around one billion (109) ultrafine bubbles. The range depends on water quality, so please tell us about your sample.
BLASE X is designed for ultrafine bubbles around 100 nm. For microbubbles (approx. 5–450 µm), please consider BLASE MICRO.
Yes. As a test laboratory officially registered with the Fine Bubble Industries Association, we can begin with a sample evaluation before any equipment is considered.
Flow cells, cell sets, cells, cell stands, window plates, the PDF analysis app and PSL standard particles, among others. We propose what suits your application.
This depends on the destination and specification. Please tell us the country of installation and the application via the enquiry form.
