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.
Mitegen M2-L18SP-A2, MicroMount Medium Aperture Assortment - 5 each of 75, 100, 150 and 200 micron aperture mounts; 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.

Instech Loop Connector for 2 Channel Rat Vascular Access Button™, Primer
The Instech VABR2L is a two-channel loop connector designed for rats using the Vascular Access Button™ system. This specialized shunt links the red and white ports of a 2-channel button to create a continuous extracorporeal circuit, typically between a bile duct catheter and a duodenal catheter. By allowing bile to circulate naturally during recovery or between sampling intervals, the loop maintains the animal's physiological homeostasis and prevents bile salt depletion. The low-profile connector attaches magnetically, providing a secure yet low-stress connection that allows for pair or group housing when used with a protective cap.
Features
- Product Type: 2-channel loop connector (shunt)
- Compatibility: 2-channel Rat VAB™ (VABR2B)
- Application: Bile duct to duodenum bypass
- Connection: Magnetic quick-connect
- Benefit: Maintains enterohepatic circulation
- Housing: Compatible with VABRC protective caps
MTC Bio Inoculating loops, 1µL, flexible PP, sterile, individually wrapped, 1000/cs
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 researcher’s ability to collect and transfer samples efficiently. The flexibility allows for more precise sampling from cultures, especially when working with small or delicate colonies.
