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

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.

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.

WORKS FOR THE PROJECT

Pros- Easy to take apart and put back together -Lightweight -InexpensiveCons-Calibration nut does nothing to change quantity -The actual quantity of liquid drawn is highly inaccurate. It reads 1000uL(1mL) too high. Yes I said one entire mL too high. I set to 2.0 (2000uL) or 2mL. I used a standard 5mL pipette tip and drew water. What did I see? The water was to the 3mL mark. I set it 3.0(3000uL) or 3mL. I drew water. The water was to the 4mL mark. I repeated with a setting of 1.0 with the same result. The lowest setting it will go is .25, which ended up being 1.25 mL. This means that this pipette actually draws 1.25mL to 6.25mL instead of the stated 1-5 mL. -It also dripped to start. I did what other have done and took it apart to spread around the grease on the o-ring. It did help greatly.Conclusion- For hobby use it is ok but if precision is needed then stay away. Pay the higher price for higher quanlity.
