5 mL Adjustable Volume Pipette, 1-5 mL Lab Single Channel Micro Pipettor, Manual Liquid Micropipette for Laboratory Scientific School Home

Great pipette for lab and compounding pharmacy. Very easy to change the tip and simple to use. We use it almost everyday and the quality of the pipette is great and long lasting.

I use this to quickly add precise amount of nutrients to water before feeding my plants.I was using typical pull syringes and that’s fine for clear or very light colored nutrients, but with some nutrients the liquid is very dark and hides markings on the syringe making it tedious and annoying to see quickly how much I’m pulling/administering.With this I just set it for the desired amount and bing bang boom I’m loading and distributing quickly and precisely. Makes watering a breeze.Tip: if you should choose to adopt this tool for said chosen purpose I would offer a tip: you only need one pipetter but many tips to avoid cross contamination, obviously.I reuse the tips, keeping them in labeled designated test tubes in a rack - you can easily stick the pipetter into the top of the tube to grab the tip and after using it pop it off directly back into the test tube. Ill add a pic later if I remember.Accuracy - ⭐️⭐️⭐️⭐️⭐️ I didn’t test it down to the micromil but to the mil it’s dead on, so for my purposes it gets a strong 5 stars for accuracy.Tools make life easier. That’s their purpose. This tool serves it’s purpose handsomely.

So I’ve worked in a few labs and had to use Pipettes to draw samples. I found this from 1-10mm and thought it would streamline my nutrient process for gardening. It did, but it took me a little work to get there.When I first took it out of the package I filled a glass with tap water and began testing it. It dropped everywhere. I got upset and arranged an exchange. After I got off the phone I started playing with it and the accessories.First thing I did was take the cover off the end. It twisted off. Then there was a black housing for the piston. It turns a couple degrees then pulls straight off. There is a rubber plunger in there with silicone grease on it. I smeared the grease around better reassembled and viola! It worked!!Now I went to my garden and grabbed a graduated cylinder with 1ml markings. I ran through testing it at 10, 5, 3, and 2 ml (my common nutrient doses) and the meniscus sat right on the Correlating line.Not bad, I was happy and I cancelled my return. I packed it all up and put it away. Later on in the evening I was going to mix nutes and I thought it was a great opportunity to break it in. Well, wouldn’t you know it started dripping again. I switched over to my disposable pipettes and when I got done I started trouble shooting.I got the instructions out and read through them thoroughly. I payed particular attention to forward and reverse pipe tying instructions. I followed them step by step and drew 20-30 samples in a row with no drips.All in all I’d say it’s a great little device, accurate enough for my needs. I think it’s a little finicky, but that could also be operator failure. YMMV, but I think in the long run it’ll work just fine.

Adjustable, simple, reliable…. It’s made my projects MUCH easier.

WORKS FOR THE PROJECT

One of the worse purchases I have ever made and I make LOTS of purchases! I rarely write reviews, but had to on this pipette. The readings are all over the place. All I want and expect it to do is measure PRECISELY 10ml of my aquarium water so that I can run tests for nitrate, alkalinity, magnesium, etc. Every time it gives me a different reading! One time it's 12 ml, another 11ml, another 13ml! I then tried dialing it to 8ml since it was consistently 2 ml off and even that fluctuates! It was supposed to help make testing my water parameters easy, but it's a waste of money! Will collect dust on my shelf!

Works as intended
