Tech TeamIndustrial Precision Luer Lock Tip Applicator, 20 mL Syringe, Non-Sterile, Dispense Adhesives, Oil, Lubricants, Sealants, Alcohol, Includes 6 Syringes and 6 Nozzles with Caps, by Tech Team
Main highlights- These syringes are NON-STERILE and are intended for industrial and hobby use. The ability of the syringe to work easily is directly dependent on the viscosity of the fluid. Thin fluids work well, thick ones can become problematic.
- The syringes feature a polypropylene body and plunger with a vinyl seal. Using volatile solvents and corrosive chemicals such as, but not limited to, lacquer thinner and acetone should be avoided, and a 24-hour compatibility test is advised for any fluids that fit this category. Appropriate safety gear such as gloves and eye protection should be used at all times.
- The set includes six (6) syringes and six (6) nozzles with break-away caps.
- Each applicator nozzle comes sealed with a break-away cap on the end. Simply break the cap off, reverse it and use it to seal the end of the applicator tube. The applicator tube connects to the syringe body with a secure Luer Lock twist-on connection.
- 20 mL polypropylene syringes with secure Luer Lock applicator nozzles and caps for drop by drop application of oils, lubricants, adhesives, inks, paint, perfume, flux, and essential oils. Each syringe has a clearly marked ml scale for accurate measurement of fluids which makes it ideal for measuring additives for 2 cycle engine fuel mixes.
