5 µL, PS, Lavender — 333-5006-U1I | Caplugs® Evergreen

InocuLoop™ 5 µL Inoculating Loops with Spreader — Sterile, Polystyrene, Lavender, Individually Packed (333-5006-U1I)

The InocuLoop™ 5 µL loop and spreader combination tools are individually wrapped sterile inoculating loops molded from polystyrene, supplied in lavender for easy visual identification. Each unit features both a calibrated 5 µL loop end and an integrated spreader, providing two essential microbiology functions in a single disposable instrument. Part number 333-5006-U1I is well suited for streaking plates, transferring fixed inoculum volumes, and spreading liquid samples across agar surfaces without the need for separate utensils.

Technical Specifications

Applications

• Streaking agar plates for microbial isolation using the calibrated 5 µL loop end
• Transferring a fixed, reproducible inoculum volume in quantitative plating workflows
• Spreading liquid samples or dilutions evenly across agar plate surfaces with the integrated spreader
• Routine clinical, environmental, and research microbiology plating procedures
• Single-use sterile inoculation where heat-based loop sterilization between uses is not practical

Material & Chemical Resistance

These inoculating loops are molded from polystyrene, a rigid, cost-effective material well suited to single-use disposable labware. Polystyrene performs reliably with aqueous samples, standard biological buffers, and typical culture media. Because polystyrene is not autoclavable and is not resistant to acetone, alcohols above 70%, or aromatic and chlorinated solvents, these loops are intended for single-use disposable applications only and should not be resterilized by heat or chemical means incompatible with the material.

Quality & Procurement

Made in USA, Caplugs® Evergreen InocuLoop™ inoculating tools are manufactured under ISO 9001 quality management and supplied treated and sterile in individual packaging, ensuring each loop is ready to use directly from the wrapper. Produced from BPA-free, phthalate-free, latex-free resin, these loops meet the demands of regulated clinical and research environments. LabSupplies.com is an authorized dealer and ships from USA inventory, with volume pricing available for high-throughput laboratories and institutional procurement programs.

Frequently Asked Questions

Are these inoculating loops ready to use straight from the package?
Yes. Each loop is individually packed, treated, and sterile, so it can be used directly from its wrapper without any additional sterilization step.

What is the calibrated loop volume, and why does it matter?
Each loop is calibrated to deliver 5 µL, providing a reproducible inoculum volume that is important for quantitative plating, colony counting, and standardized microbiological procedures.

Can these loops be resterilized and reused?
No. These are single-use disposable tools. Polystyrene is not autoclavable, and the loops should be discarded after a single use in accordance with standard biosafety and waste disposal practices.
