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 Twist Hook, Twist Right Only
Twist right only, made from all stainless steel construction.
Cole-Parmer Argos Technologies Inoculating Streaker Loops, Small, Blue; 2.5 mm ID; 5/Pk
These loops attached to a light-weight aluminum handle are made of high quality twisted nichrome wire. The handles are insulated to protect the hand, during use. The loops have been designed to slide along agar surfaces without cutting or tearing. Loops and handles cool rapidly, after sterilization. They are offered calibrated (1l & 10l) or non-calibrated. Non-calibrated loops and handles are available as small, medium or large and color coded for easy identification.
Cole-Parmer Argos Technologies Inoculating Needles, 3", 25 Gauge; 12/Pk
Needles are made from high quality nichrome wire that cools rapidly after sterilization. Available with or without handle and straight or angled needle.
