2Pcs 30ml Plastic Syringes and 2Pcs Blunt Needle Tip Luer Lock 14Ga x 10", Great for Scientific Labs, Measuring and Refilling

I bought these for putting methylene blue in two small bottles because otherwise it's very extremely messy and using these, I absolutely have NO MESS!!!!! You can use these for anything basically any kind of product to redistribute it somewhere especially into small little bottles from a large bottle or something that you're making It's just wonderful The metal part literally screws onto the syringe that holds quite a lot I was having a heck of a time trying to transport that stuff and I lost so much of the methylene blue and you don't want to lose it plus it stains everything but with these syringes in the metal extension I can reach all the way down into the large bottle with a small top whereas I couldn't before with a different type of a syringe it didn't fit and this way it stores the product right into the syringe nicely not one drop that I lose because the tip of the metal is so tiny It stores it in there and not a drop has been lost every single time I've done this four times now So I am so grateful for these They are just fantastic! I only need one but it's great having a backup just in case you know It's always best to have backups with anything in life actually in my opinion but this one will last a very long time It looks brand new I just wish water through the syringes after I get done with the methylene blue back and forth until it runs clear and unscrew the metal piece from the syringe and shake out whatever moisture may be inside and simply just let them sit out to dry for a logical amount of time which is not too long and put them back in the drawer... Actually I don't always let him sit out I just put it back in the drawer which I'm sure would be fine It's really nice stainless steel the middle tip is that screws onto the syringe The plastic is really strong and sturdy It's really solid the whole device set up and it's secures perfectly when you screw it in the end I was pleasantly surprised The first time I used it and discovered that it screwed on so tightly and securely that was a really nice touch for them to create it like that I thought it just snapped in the bottom and was trying to stick it in the end and discovered that it screwed in and wow Yes it's very nice product Very solid will last indefinitely really a lifetime I'd say have taken care of properly Thank you so much Greatest blessings upon you all

I mistakenly put the wrong ink color into one of the tanks of my HP Smart Tank 6000 printer. This tool worked perfectly in allowing me to extract the ink from the wrong tank & put it into the correct tank.ide

Used this to target hard to reach aiptasia. Killed it on contact!

Just what I needed. The markings wear off after a few uses. I know it says dust 1use but I use them for awhile.

This was the only item that I could find to help remove the ink that I put in the wrong well of our printer.

Horrible!!! Spend an hour messing around with this stupid thing, doesn't work at all, couldn't get it to prime, don't waste your money, threw it out in the garbage.

Useful for delivering liquid fertilizer to specific areas of my aquarium for plants.

Works great for what I use them for. I use them to feed my aquarium plants their liquid food.
