10 pack 30ml Syringes luer lock with Caps, Plastic Syringe for Scientific Labs and liquid Dispensing Metric Multiple Uses

I purchase these syringes to prime a small diffusion pump in one of my company's products. The pumps are hypersensitive to air bubbles because of thier rotational motor design. If there is one small bubble in the pump, it instantly cavitates and makes a noise I have no way to describe, but it is one of those noises that has a catastrophic squeal that you inherently know is signaling the death of the pump.We also ship the syringes with a tube on the end to our customers so they can prime the pump when the product arrives. I like the syringes because they are very tight and are designed to allow air to escape easily as the bubbles crawl up the point of the plunger. They are very consistant and reliable and have never had a complaint. You can hit them pretty hard with fluids that have a higher viscosity and they perform perfectly.These syringes are a good deal - reliable, professional, and an excellent value.

When drilling, tapping, or threading metal, use of a good lubricant is crucial. The use is using too much cutting oil, making an unnecessary mess and wasting that expensive consumable. These syringes allow precise control of the location and amount of cutting lube (Tap Magic for me). I’m using the 30 mL size, but now think the 20 mL size would be better for my use since I’ve been much more efficient in my cutting oil use than expected.

We bought these to help my dad take the right dose of medicine multiple times a day he needed to take 30 mL 4 times a day so I bought these so that he didn’t have to pay attention to little dashes or numbers he just needed to fill the syringes up all the way and take that as his dose four times a day. Worked perfectly

If this syringe is needed for sterile purposes, it's a one time use. Not able to be autoclaved.

Liked the size, but fairly hard to pull liquid from wound

Bought this for son’s science project and they were in excellent condition. Everything works and they have no defects.

Used to store taps and milling machine cutters. Seal the needle end, add a small sponge (stops rattling) soaked in oil, at the top add another sponge. Rust proof, secure storage for expensive parts. Try it!

This product works fantastic for accurately dispensing acrylic into tight places, however it can be tricky to ensure that there are no bubbles. I attribute this to a less then great suction ability. Overall this item is a fantastic price for a good performance.
