Disposable USP Grade Cotton Swabs

Available in multiple lengths and head shapes to accommodate deep-vessel sampling or precision detail work.

Features:

• Precision Head Styles: Choose the Pointed Head (394325) for tight crevices and electronic components, or the Small Head (394345) for low-volume broth inoculation.
• Autoclave Compatible: These wood-shaft swabs can be safely autoclaved, allowing you to prepare sterile swabs for sensitive clinical or aseptic procedures.
• High Absorbency: The USP grade cotton ensures maximum pickup of liquid specimens and efficient application of reagents or cleaning solvents.
• Extended Reach: The 6-inch models provide ample length for reaching the bottom of standard test tubes or navigating around complex machinery parts.

Laboratory Usage Tips:

• Sterile Technique: When autoclaving, ensure swabs are placed in a sterilization pouch or wrap. The wood shafts can hold residual moisture, so include a proper drying cycle to prevent the cotton from remaining damp.
• Cleaning Sensitivity: When using with cleaning solvents (like Isopropanol) on delicate optics, always apply the solvent to the swab first rather than dipping into the primary container to avoid cross-contamination.
• Single-Use Policy: To ensure sample integrity and prevent cross-contamination in microbiology, always dispose of swabs immediately after a single contact with a specimen or media.
