PR1MA™ Disposable Inoculating Loops and Needles

 

Polypropylene & Polystyrene.

 

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.

 

Flexible Polypropylene Loops

• Excellent for maneuvering in Petri dishes, test tubes, and other tight spaces
• Gentle on delicate microbial colonies
• Allows for precise sample collection and transfer 

Rigid Polystyrene Loops & Needles

• Ideal for precise streaking and isolation of colonies
• Suitable for dense or viscous samples
• Provides better control during quantitative assays

Key Features

• Sterile and single-use – no risk of contamination, no flaming needed
• Available in loop and needle formats
• Hexagonal shaft for improved handling and control
• Smooth loop surfaces to prevent agar damage
• Available in flexible (polypropylene) and rigid (polystyrene) materials 

These inoculating tools are perfect for laboratories looking for consistent, contamination-free performance in microbial handling and culturing.
 

Inoculating Loops and Needles

Our Inoculating Loops and Needles are smooth and flexible to facilitate uniform, smooth streaking without damage to media/gel surfaces. The needles are straight and suitable for removal of single colony specimens. The loops are extra-smooth and constructed of polypropylene and rubber. Both the loops and needles are packed sterile in safe, tamper-proof, zip-seal resealable bags. Cross contamination due to improper sterilization is eliminated. They can be used under hoods without danger, are color coded for ease of size identification, and are extra long to reduce the risk of contamination. Certificate of conformity is available upon request.
