InocuLoop™ Sterile Needle & Spreader Inoculating Loops — Polystyrene, Green, 25/Box (333-5012-G10)

The InocuLoop™ Needle & Spreader Inoculating Loops are a dual-function disposable microbiology tool, combining a needle tip and spreader in a single sterile instrument for streaking and spreading on agar plates and other solid media. Supplied treated and sterile in convenient 25/Box packaging, part number 333-5012-G10 is molded from green polystyrene for easy bench identification and lot-to-lot consistency. These single-use loops eliminate the need for flame sterilization between transfers, reducing contamination risk and improving workflow throughput in routine microbiological work.

Technical Specifications

Applications

• Streaking and spreading microorganisms on agar plates and solid media
• Single-use inoculation of culture media to prevent cross-contamination between samples
• Colony isolation and subculturing in clinical, environmental, and research microbiology
• Teaching and training laboratories where disposable, pre-sterilized loops simplify workflow
• Quality control microbiology in pharmaceutical, food, and beverage testing environments

Material & Chemical Resistance

These loops are molded from polystyrene, a clear, rigid thermoplastic well suited to handling aqueous biological samples and standard microbiological media. Polystyrene is compatible with aqueous buffers and dilute biological solutions but is not resistant to acetone, alcohols above 70%, or aromatic and chlorinated solvents, which can craze or dissolve the material. As with all PS labware, these loops are not autoclavable; however, because they are supplied pre-sterilized, autoclaving is not required or recommended — dispose of after each use per your facility's biohazard waste protocols.

Quality & Procurement

Made in USA, Caplugs® Evergreen InocuLoop™ instruments are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free resin. Each loop is individually treated and sterile, providing reliable, ready-to-use performance straight from the box. LabSupplies.com is an authorized dealer and ships from USA inventory, with volume pricing available for high-throughput labs, core facilities, and institutional procurement programs.

Frequently Asked Questions

Are these inoculating loops ready to use directly from the box?
Yes — each loop is supplied treated and sterile, so no flame sterilization or additional preparation is needed before use. Simply open the packaging and inoculate directly.

What does the "Needle & Spreader" designation mean?
This dual-function design incorporates both a needle tip, useful for picking and stabbing inoculations, and a spreader end for distributing organisms across the surface of solid media — combining two common microbiology tools in one disposable instrument.

Can these loops be reused or autoclaved after use?
No. These are single-use disposable instruments and are not designed for reuse or autoclaving. Polystyrene is not autoclavable, and re-sterilization could compromise both the material and sterility assurance. Dispose of after each use according to your facility's biohazard waste guidelines.
