Industrial Syringes with Blunt Tip Fill Needles. Syringes are of the disposable type. They may be used multiple times for various applications. Due to the large gauge/size of the filling needle, these syringes work well with viscous liquids. The tips on the needles are blunt and flat so they cannot pierce skin. The needles are non-sterile. They may not be used for injection or any medical purposes. The markings on the syringe barrels are made with a high quality ink which is resistant to rubbing off. Our needles have a large gauge and are a true blunt tip so that cutting/scrapes are unlikely when using our syringes.
