Karlling 250ML Large Big Plastic Hydroponics Nutrient Measuring Syringe

They’re are ok. They get the job done.

We purchased these to repair a MEL science experiment kit and they worked great.

Its plastic, and it is impervious to 88% lactic acid - we use this to drop pH when making beer. Markings are clear and 1 ml each. Nuff said.

Very satisfied with this one. Purchased the 20 mL. The tip is the same size as a standard dosing syringe (like the ones that come with children's medicine). The tip is smaller than many of the other larger capacity syringes which are 0.15 in/0.38cm. It fit great inside my noseFrida pacifier doser which is what I bought it for.

Suction and press out in this is great. Tube did not stay attached to syringe, so my hands got covered with oil trying to make it work. Poor construction.

I have to decant large quantities of a liquid into smaller containers for customer samples. The first three pulls and fills with this were great and I couldn't have been happier. However, nearly every subsequent pull to fill the syringe resulted in the plastic pull slipping off of the rubber seal. This resulted in a hefty splash back into the original container and another splash of product all over my face, arms and upper body. It required me to push the plastic plunger back into the syringe and force the liquid out, then get a wire hangar to force the rubber seal back out of the syringe. This tripled and often quadrupled the amount of time it took to fill the small sample containers. However, I dealt with it as it was the only large syringe I could find at an affordable price. Today, I returned to fill more sample bottles and while trying to reassemble the syringe (putting the rubber seal and plunger back into the syringe) it would not go back in. I put some water around the edges to grease the edges (so to speak) and it still wouldn't re-enter the syringe. Disappointed. On top of that, while trying to push the plunger back in, the damn thing slipped from my hand and the nozzle smashed into the table and broke. 8-[ I'm on here this morning to purchase another syringe (from another manufacturer), but needed to post this review to alert others not to expect a long service life for the $18 plastic syringe.

It’s the perfect size, however, it’s really difficult to push the saline through, vey hard.

Okay, I bought this for a weird reason. I bought this to remove water from afountain that I have in my finch birdcage. It's genius actually, I don't have to removethe whole fountain (though I will to wash it out once a week) but to change the water(freshen it up) I can just use this syringe. Terrific. At first I thought an aquariumhose was the way to go but that was too large. This is large, has great suction andshould last a long long time. :)

Used for measuring chemicals for a hot tub. Not easy when the tube holds a load, but still does the job. As stated the tube has a tendancy to fall off, which if you have chemicals or something in it, can get messy.

A piece of the syringe was broken and the broken piece enclosed within the syringe (probably for me to try to attempt to glue it together).

Used it to extract braking fluid from car, very convenient to use.

Used for motorcycle fork oil measurement

I use this for drawing liquid from bottles it is a precise method of measurement
