Yikki 5 x Monoject Curved 412 Tip Syringes 12 Cc , 5pcs - Tyco/healthcare- Kendal

When first tried it, it squirted sideways. Huh! THE TIP IS TINY * 2mm OD and 1mm ID*, I didn't notice a burr on the tip that blocked the end. I carefully trimmed off the tip about 2 mm back with a good scissors and I was good to go.After I trimmed the tip and put water in the reservoir, it ran out the bottom. I had to put my finger tip on the tip to block the hole, then put some water in the syringe. I then place the plunger lightly in the syringe and turned the unit so the tip was upwards. I slowly pressed the plunger to vacate some air and turn the syringe so the tip was down. No water leaked because of the vacuum created by the plunger. It acted like a pipet would.I needed this syringe to get into a tight spot with some bleach and this did the job. The tip, 2 cm from the base, curves off to a 60° angle. BTW, I immediately rinsed out the syringe to avoid the bleach from possibly degrading the plunger.And brother, does it squirt out a strong stream. I was impressed.Update: 2/7/2015. WELL, what a dunce! I just realized that the syringe can be fully assembled and with the plunger all the way in, you can dip it in water or some other fluid and pull the plunger back sucking the fluid up the chamber through the tip. No muss, no fuss. Super easy and a great tool. Sorry for being dopey.

These syringes are very well made. I'm using them for applying glue in tight spaces and they're perfect for my needs.

Great syringes. I've used these for years and 5 of these for the price is a great buy. My first use like many, was after wisdom tooth extraction. But of course there's thousands of other uses for them. From hobby/craft applications to mixing up your favorite hard fruit to bleeding brakes, these can be used for many different things.One thing to keep in mind is that some substances will either bond with or break down the rubber plunger, so you might get one use out of a syringe before it has to be trashed. One way to extend the life of the syringes is to pull the plunger back before you draw any liquid, or use a tube on the end of the syringe to siphon.Cleaning... They're not sterile, if you need something sterile, you need a different syringe. But, keeping them clean for oral hygene is a simple matter of mouthwash, salt water or hydrogen peroxide. I woudn't use alchohol to clean them, the alcohol can break down the plunger I've found. But they're so inexpensive, if I had to worry about getting one really clean, I'd toss it into the recycling and buy some more.

I use these to remove tonsil stones and to clean between my teeth. I don't think these are really meant for oral hygiene, as several of the syringes in the 5 pack has plastic barbs that on the end of the tips, which scratched the inside of my mouth when I tried to use them. Trimming off the barb was only moderately successful, it was still a little scratchy after that. I need the small stream to clean out small cavities in my tonsils, so trimming too much off the end wasn't an option.For the syringes that didn't have the plastic barbs at the end, they worked quite well at the beginning. However, after a month or two, the lubricant on the inside wears out and it takes Herculean strength to get it to squirt anything. At this point, they're cheap enough to buy some more (my 5 pack lasted me about 10 months, despite a few having barbs).

I use these for extracting herbicide from containers without spilling. Also useful for Albizzia control applications.
