1 µL, PS, Blue — 333-5001-B10 | 25/Box | Caplugs® Evergreen

InocuLoop™ 1 µL Inoculating Loop & Spreader — Sterile Polystyrene, Blue, 25/Box (333-5001-B10)

The InocuLoop™ 1 µL Loop & Spreader combines an inoculating loop and spreader in a single sterile instrument, molded from blue polystyrene for easy visual identification at the bench. Supplied treated and individually sterile in convenient 25/Box packaging, part number 333-5001-B10 is designed for consistent, disposable use in routine microbiological inoculation and plating workflows. The fixed 1 µL loop volume delivers a standardized inoculum, eliminating calibration steps associated with reusable wire loops.

Technical Specifications

Applications

• Quantitative inoculation of agar plates using the calibrated 1 µL fixed-volume loop
• Streak-plating solid media for bacterial or fungal colony isolation
• Even spreading of liquid samples across agar surfaces using the integrated spreader end
• Clinical, veterinary, and research microbiology workflows requiring single-use sterile disposables
• Teaching and training laboratories where consistent inoculum volume and ready-to-use sterility are important

Material & Chemical Resistance

These inoculating loops are molded from polystyrene, which provides the rigidity needed for controlled loop and spreading technique. Polystyrene is well suited to aqueous biological samples, standard culture broths, and saline-based suspensions. As with all PS labware, polystyrene is not compatible with acetone, alcohols above 70%, or aromatic and chlorinated solvents, and it is not autoclavable — making single-use disposable design the appropriate format for this material in sterile microbiology applications.

Quality & Procurement

Made in USA, Caplugs® Evergreen InocuLoop™ instruments are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free resin and are supplied treated and sterile for immediate use. LabSupplies.com is an authorized dealer and ships from USA inventory, with tiered pricing available for high-volume institutional and clinical laboratory purchasers.

Frequently Asked Questions

Are these inoculating loops ready to use straight from the box?
Yes — each loop is supplied treated and sterile, so no flaming or additional sterilization step is required before use. Simply remove from packaging and inoculate directly.

Can the same instrument both loop and spread a sample?
Yes. The combination design provides a calibrated 1 µL loop on one end and a spreader on the other, allowing both inoculation and plating tasks to be performed with a single disposable instrument.

Are these loops suitable for use with alcohol-based disinfectants or solvent-containing reagents?
No — polystyrene is not compatible with alcohols above 70%, acetone, or aromatic and chlorinated solvents, which can craze or dissolve the material. These loops are intended for single-use with aqueous biological samples and standard microbiological media.
