Precision and Efficiency

Sterile microbiological loops and needles from Biologix are the best solution in laboratory equipment in every microbiological laboratory. Microbiology loops have been designed to work with a wide range of cell and microbiological cultures, ensuring the best possible results. Sterile microbiological loops and needles are designed with optimal stiffness and consistent dimensions, made of the highest quality plastic to ensure comfortable, ergonomic work. They are distinguished by ultra-smoothness when collecting cells.

Sterile microbiology loops and needles are extremely important tools in the field of microbiology. These laboratory tools are characterized by precision and effectiveness, which makes them irreplaceable when performing various microbiological tests and analyses.

Sterility and Safety

Loose loops and needles are available in a sterile form, which is extremely important in microbiology, where avoiding contamination is crucial. The microbiological diagnostic materials described are subjected to rigorous sterilization processes, such as UV radiation or autoclaving, to ensure the purity and safety of samples.

Reliability of Ez and Needle

Biologix products are known for their high quality workmanship. The loops and needles are made of durable materials that are resistant to chemicals and microorganisms. Thanks to this, they ensure reliability and long-term use. Biologix pays attention to user comfort. The loops are contoured to provide a comfortable and secure grip, which facilitates the maVATulation of microbiological samples. The ergonomic shape prevents hand fatigue during long-term work in the laboratory.

  • Microbial Sampling: Inoculating Loops are used to collect precise amounts of microorganisms from bacterial cultures, yeast cultures, agar plates, and other sources. This allows scientists to transfer microorganisms from one container to another for further study, identification or cultivation.
  • Microbial Screening: Inoculating Loops are also used to screen microorganisms on agar media. Scientists can apply a sample of microorganisms to an agar surface, creating uniform colonies of microorganisms that can then be analyzed for phenotypic or genetic characteristics.
  • Preparing microscopic smears: Inoculating Loops are useful for preparing smears of microorganisms on microscope slides. They can be used to take samples from a bacterial or yeast culture and then smeared onto a slide so that the microorganisms are evenly distributed and can be observed under a microscope.
  • Genetic Transfer: In molecular biology, Inoculating Loops are used for gene transfer. For example, they can be used to transfer plasmids that contain the gene of interest into bacterial cells. Inoculating Loops allow for precise transfer and introduction of genetic material into cells, which is important in many genetic experiments.
