This article compares performance between flocked swabs and standard swabs, highlighting key differences in sample collection, yield, and usability for labs and forensics.
Core Performance Metrics
-
Sample Collection: Flocked swabs (3D nylon fibers) trap 40–50% more cells/DNA; standard swabs (cotton/polyester) have lower surface area for adhesion.
-
Release Efficiency: Flocked swabs release >90% collected sample into buffers; standard swabs retain 30–40% due to fiber absorption.
-
Handling & Durability: Flocked swabs have rigid shafts for precise targeting; standard swabs may fray or bend, risking sample loss.
-
Contamination Risk: Flocked swabs (non-absorbent fibers) reduce carryover; standard swabs’ porous material may trap contaminants.
Key特点
-
Flocked Swabs: High-yield, efficient release, ideal for low-abundance samples (trace DNA).
-
Standard Swabs: Cost-effective, suitable for non-critical sampling (routine clinical tests).
Application Scope
-
Flocked Swabs: Forensic trace DNA, viral testing, genetic research (high-yield needs).
-
Standard Swabs: Routine clinical sampling, non-sensitive microbial tests (budget-focused).
