Fully automatic two-insect detection and analysis system
Waterborne protozoan testing depends as much on recovery rates and reproducibility as on detection. The published figures here are specific enough to test against a laboratory’s own validation requirements.
Water utilities and public-health laboratories monitor Giardia lamblia cysts and Cryptosporidium oocysts through concentration, separation, and identification. The Guoke Medical Fully automatic two-insect detection and analysis system belongs to the company’s Microbial Culture and Analysis System portfolio and combines filtration enrichment with automated scanning.
The stated workflow uses density gradient and membrane concentration for collection, then DAPI, FITC, and DIC imaging with automated image analysis to locate oocysts and spores. Multiple hosts can run in parallel, with up to ten channels.
Published figures include filtration recovery ≥100%, elution ≥85%, immunomagnetic separation ≥90%, and relative standard deviation ≤8%. The filtration figure exceeds 100 percent as written, which should be clarified before it is used in method comparison or tender documents.
Samples up to 100 NTU turbidity are stated as within scope, relevant where surface-water quality varies seasonally.
Configuration, pack size, compatible options, documentation, minimum order quantity, and lead time are confirmed at quotation rather than published, so buyers should expect a specification-matching step.
The decisive question in procurement is whether stated recovery and reproducibility hold under the laboratory’s own sample matrices and accreditation requirements, and whether method documentation supports the intended reporting use.
Why it matters:
Automation reduces reliance on manual microscopy, but recovery, RSD, and method documentation decide whether results withstand regulatory review.
