Its tip is a wire made of platinum or nichrome, the latter being inferior but less expensive. The wire forms a small loop with a diameter of about 5 mm. This loop is handy for taking an inoculum from a liquid by using the phenomenon of surface tension.
The loop is used to cultivate microbes in Agar jelly and to use the streak manouvre to transfer microbes.
