1ml Syringe Luer Lock (1-Pack) - Shatter & Heat Resistant, Borosilicate Glass Syringe 1ml for Use With Liquids, Glue, Oils, Ink | Premium Quality for Use in Labs & for Crafts

Good stuff. Perfect for filling 510 carts. Eventually wears out like anything so if you plan to use continuously, buy the 10 pack like I did for the day it wears out. Originally used 10 unit syringe but switched to one. Easier to use and when it wears out or breaks, much less product loss.

I recently purchased the Kopperko Borosilicate Glass Syringe, and it has exceeded my expectations in every way. The 1ml capacity is perfect for my needs, and the heat-resistant borosilicate glass construction ensures it’s durable and reliable. I primarily use it for filling vape cartridges that require the application of heat to make the solution soluble, and the Luer lock design makes it incredibly easy to attach and secure the 14GA blunt tip needle.What sets this syringe apart is its versatility and precision. The blunt tip needle is non-hypodermic, making it safe and ideal for use with a variety of substances, including liquids, glues, oils, and ink. The syringe's construction allows for smooth and controlled dispensing, which is essential for delicate tasks. Overall, this Kopperko glass syringe is a high-quality, versatile tool that has become indispensable in my projects. Highly recommend!

Great quality

in my perfect world these would be made of all glass but i’m guessing that’s hard to manufacture. The plug comes undone from rod if you have high viscosity oil so super glue is needed to keep it in place otherwise one of the best on the market.

Was on time and worked and functioned properly I recommend

Does not suck well. The vial is glass but the pusher is plastic, and the end comes off too easily.

These fit well over a gram and are easy to clean and reuse. They are also durable to heat up. Great value for the money!!

Just ask your pharmacy for more disposable syringes. We used this less than a month before it was unusable. There is a rubber piece that connects to the part that you push and pull, and it just won’t stay connected anymore. The rubber has loosened up too much and won’t stay screwed onto the other piece.We needed this for the clear markings for administering our baby’s daily reflex medicine. The disposable syringes’ markings wear off after regular washing. When I refilled the prescription this time I just asked for additional syringes. This super cool glass guy will go in the trash.
