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.
Cole-Parmer Essentials Inoculating Loop, Platinum, 3 mm ID, 26 Gauge, 70 mm
Calibrated loops 01850-00 and 01850-02 are ideal for milk samples. The 1-microliter loops are made of 26-ga B&S platinum wire with 15% iridium. The 10-microliter loops are calibrated and made of 19-ga B&S platinum wire with 5% rhodium. Order insulated loop and needle holder separately. Platinum loops and needles are used for transferring bacterial cultlres. These loops and needles are made of B&S platinum wire with 15% iridium added for rigidity, permitting a thinner wire for delicate work. Loops are fused to form a "perfect circle" with an inside tolerance of +/-0.02 mm to ensure accurate delivery. Order insulated loop and needle holder separetly.
Key Scientific Products THE HOOK / EACH, Angled for Easier Capture of Cryo Bead
"The Hook" has a special angle to assist in easier capture of a single CryoCare bead or other freeze systems for recovery of stored frozen microorganisms. It can also be used in a Mycology Lab as a teasing needle.
