An Ibex Sciences Inoculating Loop (also known as a smear loop) is a handheld tool used by microbiologists to pick up, transfer, and streak microscopic samples like bacteria or yeast onto growth agar. [1]
Key Product Variants & Build
- Reusable Metal Loops: Standard school and university lab kits feature a durable, heat-resistant Nichrome or Platinum wire loop. This wire is securely fitted onto an insulated aluminum rod handle. [1, 2, 3, 4, 5]
- Disposable Plastic Loops: For clinical setups requiring perfect sterility without open flames, molded medical-grade polystyrene plastic loops are available in pre-sterilized peel packs. [1, 2]
- Standard Capacity Sizes: Available in calibrated 1µL (micro-liter) and 10µL options to ensure accurate, quantitative sample handling. [1, 2]
- Dual Design Configurations: Many plastic versions feature a circular loop on one side and a straight inoculating needle on the flip side for stabbing subsurface cultures. [1, 2, 3]
Core Laboratory Functions
- Streak Plating: Spreading a microbial sample across an agar plate to isolate individual pure colonies.
- Culture Transfer: Moving active microbes safely from a test tube liquid broth over to a solid petri dish.
- Microscopic Sampling: Snagging tiny specimen amounts safely to slide under a Student Microscope. [1, 2, 3, 4, 5]
Safety & Flaming Rules for Metal Loops
- Flame Sterilization: Red-heat the metal loop in a Bunsen burner flame before and after every single use to destroy lingering microbes.
- Cooling Time: Always let the hot loop cool down for a few seconds before touching your sample. If it is too hot, it will instantly kill the cells you want to study.
- Safe Disposal: Toss single-use plastic loops straight into marked biohazard waste containers. Never try to flame a plastic loop. [1, 2, 3, 4, 5]
