Handles for Microbiology

Microbiology is the science that studies microscopic living beings, that is, those that can only be observed with the help of a microscope.

Microbiology is divided into several disciplines that study each taxonomic group of microorganisms. Some are not actually microorganisms, but their study is based on microscopic structures.

Types of Microbiological Loops and Their Use

Handles for Bacteriology
Straight or threaded handle - Not calibrated It is used to transfer a single colony to identification media, or subculture.
Ring or loop handle – Calibrated They are usually made of nichrome wire. They are used for streak sowing and inoculations in general.
Platinum ring handle – Calibrated To take 0.001 ml, for urine culture

The bacteriological loop is a laboratory instrument of the type of clamp that consists of a base that can be made of nichrome, tungsten or platinum that ends in a ring or a point. It is used to transport, drag or transfer inocula (small volume containing microorganisms in suspension) from the working solution, also called "mother solution" to the culture medium (solid or liquid) or from one medium to another (reseeding). It is also used to perform smears.

Bacteriological loops must be completely closed, with a diameter of no more than 3 mm, and with a stem no longer than 5 cm. They must be held in metal handles, not glass.

The amount of inoculum that is passed through is determined by the diameter of the final ring of the filament, which is calibrated and normally ranges between 0.1 and 0.001 ml.
