Molded from a special medical grade of polystyrene, these inoculation loops offer a strong, rigid feel to provide comfortable, stable and uniform streaking. The loops are enclosed in peel-apart packages or individually wrapped. All loops are sterilized by gamma irradiation. The 1µl and 10µl inoculation loops are available with the loop on one end and an integrated needle on the other end. A separate needle is therefore not required.
