PR1MA™ Disposable Inoculating Loops and Needles

Polypropylene and polystyrene options.

Our sterile disposable inoculating loops and needles are essential tools for accurate microbial sampling and inoculation in clinical, research, and industrial laboratories. Designed for single-use, they eliminate the risk of cross-contamination and remove the need for flaming or sterilization, improving workflow efficiency and safety.

Ideal for quantitative procedures such as urine counts, serial dilutions, and bacterial inoculation, these loops and needles are available in both flexible polypropylene and rigid polystyrene to suit a variety of microbiological applications.

The ergonomic hexagonal shaft design ensures improved grip, orientation, and control during streaking procedures. Each loop features smooth surfaces without burrs or rough edges, reducing the risk of cutting or damaging the agar surface during use.
