Description
Product Overview
The Reusable Inoculating Loops and Needle Set from Surgical Design is engineered for precision and durability in microbiology and cell culture laboratories. Constructed from ASTM‑standard nichrome wire, each loop offers superior heat resistance and maintains its shape after repeated sterilization cycles. The set includes five loops with color‑coded handles—red (2 mm), orange (3 mm), blue (4 mm), purple (5 mm)—and a black‑handled needle for versatile applications ranging from bacterial streaking to tissue manipulation. Package dimensions measure 12.56 x 4.65 x 0.51 inches and weigh only 1.73 ounces, making storage and handling effortless. The product model SL‑ILSO5 reflects a commitment to quality and consistency, as evidenced by its ranking as #18 in Lab Cell Scrapers & Spreaders on Amazon.

Usage
Designed for both academic and industrial settings, these loops excel in environments where reproducibility and sterility are paramount. Users heat the loop until it glows, then allow it to cool for approximately thirty seconds before contacting the culture, ensuring optimal transfer of microorganisms without damaging the agar surface. The color‑coded handles enable rapid identification of loop diameter, reducing preparation time and minimizing the risk of cross‑contamination. While the loops are reusable, they should be disinfected with ethanol rather than autoclaved, preserving the integrity of the nichrome wire and extending the product’s lifespan. Ideal for bacterial streak plating, colony isolation, and delicate cell scraping, the set meets the rigorous demands of microbiology, molecular biology, and tissue culture workflows.
Why Choose Us
Choosing Surgical Design means selecting a brand with a proven track record in laboratory instrumentation.

FAQ
How do I properly sterilize the loops?
Heat the loop until it glows, allow it to cool for about thirty seconds, then dip it in 70% ethanol. Avoid autoclaving, as high pressure can deform the nichrome wire.
Can the loops be used for both bacterial and eukaryotic cell work?
Yes, the loops are suitable for bacterial streak plating as well as gentle scraping of eukaryotic cell layers, thanks to their smooth, non‑abrasive surface.
What does the color‑coding represent?
Each color corresponds to a specific loop diameter: red = 2 mm, orange = 3 mm, blue = 4 mm, purple = 5 mm. The black‑handled needle is used for precise inoculation tasks.
Is the set compatible with standard incubators?
The loops and needle are designed to fit standard laboratory incubators and biosafety cabinets without obstruction, making them versatile for a range of experimental setups.
What warranty does Surgical Design provide?
We offer a one‑year limited warranty covering manufacturing defects, ensuring you receive a reliable product backed by professional support.
