Disposable Inoculating Loops and Needles for Streaking

Disposable inoculating loops and needles are commonly used inoculating, sampling, and specimen transfer tools in microbiology laboratories, suitable for tasks such as colony picking, plate streaking, serial dilution, sterile sampling, sample transfer, and microbial sample spreading. The products are typically made from PP or PS plastic materials. Disposable use reduces the need for flame sterilization steps, decreases the risk of cross-contamination, and enhances laboratory operation efficiency.

Features

Disposable use: No flame sterilization required; ready for use immediately after opening, reducing the risk of cross-contamination.
Quantitative sampling: Inoculating loops commonly come in 1 μL and 10 μL volumes, suitable for sample transfer and semi-quantitative inoculation.
Smooth loop surface: The loop opening is flat and smooth, minimizing damage to the agar medium surface during streaking.
Hydrophilic treatment: Liquids adhere more reliably, helping to reduce sample droplet loss and sampling errors.
Color differentiation: Different sizes can be quickly identified by color, facilitating accurate selection during experiments.
Loop and needle complementarity: Inoculating Loops are suitable for streaking and transferring, while Inoculating Needles are suitable for colony picking, puncture inoculation, and operations in narrow-mouth containers.

Application

Disposable inoculating loops and needles are mainly used for sampling, transferring, and inoculating microbial samples, suitable for routine laboratory microbial testing and cultivation processes.

Plate streaking: Used for strain isolation, purification, and culture inoculation.
Colony picking: Inoculating Needles are suitable for picking single colonies or small amounts of samples.
Puncture inoculation: Suitable for semi-solid culture media or deep culture operations.
Bacterial suspension transfer: Used for transferring liquid samples, bacterial suspensions, or culture fluids.

Laboratory personnel use a disposable inoculating loop to sample and inoculate the agar surface.
