Pipet/Infusion Needle, 18 Gauge, Roboz Surgical Instrument Co., Inc. (CAT#: STEM-LEAR-0621-YJL)

Pipet/Infusion Needle, 18 Gauge, model PN-7936 is manufactured by Roboz Surgical Instrument Co., Inc.
Micro injection or infusion needles (30-33 gaugel) can perform a variety of functions. They can be used for portal vein injections, thymus injections, bile duct injections, and blood or fluid extraction. These needles have a number of advantages. First, they are stainless steel therefore they can be autoclaved and reused. Second, since they are so thin the potential for clotting is reduced thus lessening the trauma to the animal. Third, there is greater control of the volume of fluid and the overall injection site.

Size: 18 Gauge; 4" Length

The letters "O. D" and "I. D. " after the number size of the needle refer to the outer diameter and the inner diameter of the needle tip. Needle sizes are generally identified by gauge size. The higher the gauge the thinner the needle and the lower the gauge the thicker the needle. For example, a 32 gauge needle is much thinner than an 18 gauge needle.
