Kopperko ホウケイ酸ガラス注射器 1パック (シングル) - 1ml注射器 耐熱ルアーロックシリンジ 実験室用 - 液体、接着剤、油、インク用接着剤注射器 - ボーナス14GAブラントチップ非皮皮下注射針

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!

I have purchased 2 of these. After the first one started having issues, I bought 2nd one just to see if it is a design issue or not. It is. The rubber stoppers end up expanding after just a couple uses, making it harder and harder to move the plunger back and forth. On top of this, the connection between the clear plastic plunger and the rubber end is literally just a screw in loose fit. Meaning that anytime it becomes even a little difficult to move the rubber inside the glass, the plastic plunger comes completely out, leaving the rubber piece still inside. I've tried several glues to no avail, as the rubbers just keep expanding more and more, making the movement harder and harder with every use. I say they are ok for the price, but it depends on what you're using this for, and if you can afford better. If you can afford better with no problem, do so. I won't be buying this one again.

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.

Perfect for my needs
