Description
Inoculation loop 50 x 4,00 mm is a laboratory inoculation tool intended for microbiological transfer, streaking and culture handling. Specified as 50 x 4,00 mm, it combines a 50 mm length with a larger 4,00 mm loop opening for applications that benefit from a wider loop geometry during sample pickup and distribution on solid media. The product is delivered in a pack of 100 pc(s), which suits busy microbiology benches that require a steady supply of dimensionally defined loops. This inoculation loop is offered by manufacturer RSG and belongs to the assortment of inoculation loops, needles, holders and related instruments used in routine bacteriology and mycology work. The 4,00 mm loop size differentiates it from narrower variants in the same series, helping laboratories match loop diameter to inoculum volume and plating technique. Compatible holder systems allow secure mounting for flame or other laboratory handling practices according to local SOPs. Country of origin is Germany. Classification under laboratory inoculation instruments supports clear cataloguing next to matching lancets, needles and loop holders for complete inoculation setups.

Questions about Loop, 50 x 4,00 mm
What is this article?
Loop, 50 x 4,00 mm is the article on this page. Luminix Health distributes RSG for laboratory use. It sits in Inoculation loops, spreaders & needles, inside Culture media & microbiology, in Microbiology lab supplies.
A loop, a needle or a spreader transfers and streaks a culture. A calibrated loop of 1 µL or 10 µL is a volume claim. A needle stabs a deep. Disposable sterile plastic and reusable nichrome are different articles. A loop that is not sterile is a mixed culture.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
