OESS Reusable Inoculating Loop with 50pcs 10uL Nichrome Needle Tips Inoculation Loop for Bacterial Tissue Culture

I ordered this for the usual purpose -- transferring inoculum to microscope slides, selecting colonies for transfer to new media etc. This is a very nice unit. It has a long handle (useful for reaching into culture tubes) and it comes with a vial of replacement nichrome loops. Nichrome is a durable choice for this purpose as it withstands flame sterilization with ease, so you don't have to throw it out after a single use. (You flame before and after use.) The construction is pretty simple -- there are two cuts at right angles to each other at the end of the threads. You insert the loop, and then tighten down the cap. There was a bit of debris from the manufacturing process that kept me from being able to insert the loop until I discovered and removed the debris. But that is a very minor defect. Anyway, this is an excellent and cost-effective choice and I recommend it highly. It also came quickly and well packaged.

they came quick. it comes with many extra loops that are in their own little tube. The handle is very sturdy, and perfect for what its supposed purpose.

I had trouble getting the loop into the handle. There was no opening to be seen or pushed into. After reading another review, they said they had to clean it out. I tried that but it still would not accept the loop but would accept a pin. I had to use the pin to wedge it open and then get the loop in. Once I got the loop in, the system worked perfectly. It's just the manufacturing did not produce the proper slits needed.

The plastic handle was significantly bent on arrival and broke off when I tried to correct it. I can replace the handle with a 3D printed part, so NBD. Also, like others have mentioned, the jaws were too narrow to accept the loops and required some prying open with a pair of tweezers. Aside from those modifications, this is a good product for the price point.

Great tool!!! Easy to use, removable tips, amazing packaging!!! -Using to inoculate agar dishes and tube slants

I used these years ago while maintaining cultures in the bio lab. They are a must have for clean transfers and inoculation of agar medium.

The metal loop attachment was flimsy so i just reinforced it with another loop, twisting them together, to pick up (isolate) heavy agar pieces (colonies).

The attachment mechanism is difficult to insert the wire into. I had to pry them apart.

not heat sterilizable.
