Forensic fingerprint brush #122L

The Sirchie Standard Size Fiberglass Brush is built for latent print development in professional forensic and criminal investigation work. Its precision-engineered fiberglass filaments retain fingerprint powder effectively, reducing the frequency of replenishment during evidence collection. The soft, cloudlike bristle cluster allows gentle application on delicate surfaces. This tool serves investigators and technicians who require reliable powder adhesion.

Limits of fiberglass filament brushes

Fiberglass bristles are designed for powder retention and gentle contact, not for aggressive scrubbing or chemical cleaning. The filaments can fracture if excessive pressure is applied, which reduces powder-holding capacity over time. The protective container with cap preserves the bristle cluster between uses but does not sterilise the brush. Users must follow standard evidence-handling protocols to avoid cross-contamination between scenes.

Check your kit compatibility before ordering

Verify that a standard-size brush fits the storage slots in your existing fingerprint field kit or carrying case. The reduced handle length may alter the balance compared to longer conventional brushes you currently use. Confirm that your team's procedures accept fiberglass filaments as a replacement for traditional animal-hair or synthetic alternatives. The protective container adds bulk, so ensure adequate space in your kit layout.
