Inoculation Loop KJ509-1 (CAT#: STEM-BC-1509-ZJF)

The KJ509-1 inoculation loop or needle is a disposable microbiological tool designed for the transfer, streaking, and inoculation of microorganisms onto or between culture media. It is manufactured from high-impact polystyrene (HIPS) that meets USP Plastic Class VI biocompatibility standards, providing reliable mechanical properties and low microbial toxicity. The loop tip is pre-formed to a defined calibrated diameter providing a fixed transfer volume per loop, ensuring reproducible inoculum delivery for quantitative plating applications. The handle design allows a stable three-finger grip for controlled streaking motions on agar plates and slant tube surfaces. Both loop (circular) and needle (straight) configurations are available: loops for streak-plate inoculation and isolation, needles for stab inoculation of semi-solid media. The plastic shaft material is compatible with standard laboratory disinfectant solutions and the product can be discarded into sharps containers or autoclaved for waste disposal. The product surface is processed for hydrophilicity, improving contact with aqueous microbial suspensions and enhancing organism uptake and release during the inoculation process. Individually wrapped sterile packaging options are available for applications requiring guaranteed sterility at the point of use. Multi-pack configurations in sterile bags provide a cost-effective solution for high-throughput microbiology laboratories performing large numbers of routine plate inoculations. The product is suitable for clinical microbiology, food safety testing, pharmaceutical environmental monitoring, and research bacteriology applications.
