Frequently Asked Questions
Are these inoculating loops sterile out of the package?
Yes. Each loop is sterilized and individually packed, so the tip stays sterile until you open the wrapper at the bench, reducing the risk of cross-contamination.
What is the difference between the needle and spreader on this loop?
This product combines two formats: a needle end for stabbing media and precise colony picks, and a spreader end for distributing inoculum evenly across an agar surface for lawn growth.
What material are the loops made from?
The loops are molded from treated polystyrene (PS), which provides rigid, single-use handling and a surface suited to consistent microbial transfer.
How many loops are in each pack?
Each pack contains 500 individually packed loops (SKU 333-5013-G1I), and pricing is listed per pack.
