Specifications
The Nalge Nunc Inoculating Loops and Needles, Sterile, NUNC 251586 Inoculating Loops, 50 comes with several key specifications that directly impact its utility in a laboratory setting. The primary component is the polystyrene material, chosen for its rigidity, smooth surface, and ability to be manufactured to precise tolerances. This ensures each loop performs identically, providing predictable results.
The 10 µL volume is a critical specification for semi-quantitative inoculating procedures, allowing for consistent and measurable sample transfer. The blue color serves as an immediate visual identifier, aiding in organization and preventing mix-ups, especially in larger lab settings. Crucially, these loops are sterilized by irradiation, guaranteeing aseptic conditions right out of the bag, which is non-negotiable for microbial work.
These specifications matter because they directly translate to improved experimental outcomes. The precise 10 µL volume is essential for reproducible dilutions and quantitative assessments, minimizing variables that could skew results. The smooth loop surfaces and surface treatment for enhanced droplet adhesion ensure that the correct amount of sample is transferred without clumping or significant loss, which is vital for accurate colony counting and isolation. The ** irradiation sterilization** eliminates the need for autoclaving, saving time and energy, while also guaranteeing a high level of sterility that is difficult to achieve consistently with reusable loops.
