Non-destructive
particle size
in closed containers
- Measure in closed containers
- In closed vials, flasks and bags
- Non-invasive, no sampling, no dilution
- Maintain sterility
Non-destructive Nanoparticle Size Analysis
What is it?
The NanoLabSizer is an analytical instrument for offline particle sizing based on Spatially Resolved Dynamic Light Scattering (SR-DLS).
SR-DLS operates in full backscattering mode and resolves scattering as a function of depth, enabling measurements inside closed containers, even with curved geometries and at higher turbidities than conventional DLS workflows typically tolerate.
Typical challenges in offline particle sizing:
- “We can’t waste sample.”
- “Opening risks contamination.”
- “We don’t want exposure.”
- “Handling changes the result.”
- “Too manual, too variable.”
- “Dilution hides the truth.”
- “Inline is overkill.”

Measure in any transparent packaging:
- Vials, Tubes, Syringes Flasks, Bags up to 3L
- Plastic vessels
- Prefilled syringes
- IV bags
The NanoLabSizer
Practical Advantages
- No sampling, no aseptic transfers: measure directly in the container (vial, syringe, flask, bag)
- Maintains sterility
- Direct non-invasive measurements in closed vials, tubes, flasks or bags (up to 3L)
- Handles wider turbidity/concentration range: no dilution needed
- Automation ready: simple pick-and-place, minimal handling
- Safety: Container stays closed for analysis
- Ideal system for process development and validation
