Capillary Probe
Collect and analyse liquid droplets safely and accurately. The Serstech Capillary Probe is a disposable, snap‑on accessory that reduces surface interference and lets you measure micro‑volumes (around 10 µL) in a controlled way—ideal when reading directly off the ground would be unsafe or unreliable.
Why organisations choose this probe
- Analyse tiny droplets: measure approximately 10 µL samples with confidence.
- Cleaner spectra: capillary sampling minimises interference from underlying surfaces.
- Rapid deployment: snap‑on design—no tools or fiddly alignment.
- Disposable: helps prevent cross‑contamination between samples.
- Platform‑ready: designed for Serstech Arx mkII handheld workflow.
Typical applications
- Field identification of liquid spills (narcotics, HazMat/TICs)
- CBRN/HazMat response where in‑situ reads are risky
- Quality checks on small liquid residues in labs/production
FAQs
Why not measure directly on the ground?
Direct reads can be inaccurate from substrate interference (e.g., asphalt or soil). The Capillary Probe moves the liquid into a controlled path for cleaner spectra.
Which instruments does it fit?
It’s designed for use with Serstech Arx mkII.
