Inoculating Loops and Needles
Devices used for inoculation, serial dilution, sterile sampling, sample transfer, and microbiological sample spreading; available in materials such as polymers, aluminum, and other metals. Includes disposable and color-coded products.
Inoculating loops and needles (sometimes called microstreakers or inoculating wands) are hand-held devices for inoculating plated or tubed growth media with micro-organisms such as bacteria or yeasts prior to incubation, multiplication, and growth. The inoculum is typically streaked onto, or stabbed into, solid agar-based media, or simply introduced and dispersed into liquid media. Inoculating loops and needles are also useful for sampling and transferring small quantities of micro-organism prior to further analysis, microscopic examination, or serial dilution.
Inoculating loops and needles consist of a handle with a terminal loop or needle that is designed to pick up and transfer a small quantity of inoculum (typically 1 to 10 μL) from a donor culture to the growth medium of choice. Some loops are calibrated and color-coded to transfer semi-quantitative amounts of inoculum.
Electron Microscopy Sciences 10 mcL Loop/Needle Yellow, Individually Wrapped
Disposable incubation loops and needles eliminating the need for flaming metal loops and exposure to airborne pathogens. Precision molded from biological inert polymers. Irradiation sterilized.
Cole-Parmer Argos Technologies Small Inoculating Loops, 2.45 mm ID; 25/Pk
These inoculating loops are made from high quality twisted nichrome wire. The loops have been designed to slide along agar surfaces without cutting or tearing. They cool rapidly and are less expensive than platinum. The loops are supplied without handles and available calibrated or non-calibrated. Brass loop handles are sold separately as models 04396-40 and -41.
Alkali Scientific CellPro Inoculating Loops Flex
These sterile disposable plastic loops and needles are designed for use in quantitative procedures such as sampling urine counts and serial dilutions as well as for bacterial inoculation Because they are pre-sterilized and designed for single use there is no risk of cross-contamination and no need for flaming The unique hexagonal shape of the shaft makes it easier to grip orientate and guide through a smooth streaking process The loop surfaces are extremely smooth with no rough edges and no flashing or burrs on the loop head This results in the elimination of cutting or gouging of the agar surface The flexibility of polypropylene loops makes it easier to maneuver them within Petri dishes test tubes or other confined spaces improving the researchers ability to collect and transfer samples efficiently The flexibility allows for more precise sampling from cultures especially when working with small or delicate colonies that could be easily damaged by more rigid instruments
Mitegen M5-L18SP-100, Dual-Thickness MicroLoops; box of 20 with 100 micron aperture loops; mounted on 18 mm rods
Simplify crystal harvesting, and obtain the best possible data from your crystals, using the most advanced lithographic cryo-loops available. Composed of X-ray transparent material, crystals can be mounted directly on the loops, reducing excess fluid, preventing damage, and making getting the crystals out of the drop easier. MiTeGen crystal mounts come in various styles and aperture sizes that allow for various approaches in choosing the right crystal mount for your application. Our mounts are hand made and inspected, packed into boxes of 20, traditionally on 18mm pins.
