Glass Graduated Droppers Pipettes Dropping Pipettes Fluid And Liquid Pipettors with Big Rubber Caps 4 Pcs (10ml)

I really liked the quality of the glass and scale markings. Good quality glass and the seller isn't joking, the blue rubber suction caps are big! They are about the size of a plum or golf ball. The pipettes come with a cleaning brush which i wasn't expecting. Very professionally boxed and individually protected as a complete set of four. Absolutely no doubt in highly recommending this product. I will buy again. Andrew

Measures quantities of liquid accurately. Useful for making fertilizer exactly to the specifications, on the bottle.Just make sure you buy a pipette pump. Those bulbs are no good and you'll get stuff everywhere.

Good quality item, works very well. Ideal for extracting liquids / chemicals from could containers due to length

Easy to use allows you to pinpoint where to put food

Arrived today good quality thank you

These pipettes don’t work, the rubber bulbs don’t fit snug enough over the end to prevent the liquid from falling straight out.So they really don’t work...

Tight fitting bulb, decent bulb allows good control of the dropper. We'll packaged for safety.I have only used 1 out of the packet so cannot vouch for consistency but they seemed decent upon visual inspection.

good

Sono pipette graduate con un'incertezza di misura sui ±0,025 ml, quindi ottime anche per un utilizzo da laboratorio.Purtroppo i tappi in gomma non sembrano esattamente fatti per la testa di queste contagocce: inserendoli nella loro sede non si sigilla il tubicino, serve spingerli oltre con decisione fino a farli aderire parzialmente al corpo della pipetta.

Ces pipettes en verre sont doublement graduées (de 0 à 5 ml et de 5 à 0 ml), par pas mini de 1/40ème de ml.Elles mesurent 327 mm de long, sans la poire (55 mm) et 8 mm de diamètre maximum.Elles sont livrées dans une boîte carton avec protection en mousse adaptée.Je recommande cet article.

Hatte bisher zwecks Länge Probleme beim dosieren vom Dünger... Die langen Glaspipetten sind genial, auch das säubern geht ratz fatz ❗️❗️❗️👌🏼

Pasable la goma se sale rápidamente del tubo de cristal están mal diseñadas las gomas pensaba que seria mejor no conprar

Ich benötige die Pipetten zum eintropfen von destilliertem Wasser in kleine Flaschen, in denen sich Aquarellfarben befinden. Sie erfüllen ihren Zweck.

Perfekt

Beim ersten Einsatz den ersten Balg aufgesteckt und wunderew mich schon dass der so locker sitzt, das kann ja nicht dicht sein.Und natürlich lief die Lösung in voller Geschwindigkeit raus. Der zweite Balg passte nun. Habe noch nicht alle getstet.

Die Qualität des Materials und der Skala sind sehr schlecht. Für diesen Preis ist das Produkt daher nicht zu empfehlen.

It's a quality item as far as construction. But what I can't stand is that it can't hold the liquid inside of it (no matter how much or little) while holding it tip-down... This is very frustrating when trying to dropper 100% bleach, or 91% isopropyl alcohol within an isolated area....If I'm just a ding-dong and there's some simple trick that I just don't know and very well should - I'd be glad to update the rating if I can, but short of plugging the end, or keeping it tilted tip-up, I haven't found a way to keep the liquid from "falling" out....

If you do any photographic chemistry at home, these are great to have. A luxury, perhaps, but real time savers. Pro-grade quality, and fine value.

First of all, these glass pipettes worked perfectly for me. I needed them to measure and transfer a liquid that can’t touch plastics. They are clearly marked, easy to use, however... the rubber bulb at the top used to siphon the liquid into the pipette can be really, REALLY hard to get onto the pipette. I was able to easily attach two and the other two were finally attached after a little struggle. If you have difficulties with dexterity, please be warned that these may not be right for you. That aside, they served their purpose, were well packed, arrived safely, and I was happy with the purchase.

I would say the only drawback of these is that the rubber bulb gets a little tiresome, and requires some skill to operate. For moving liquid between tubes, it works fine, but I didn't check it for accuracy.They do seem to be made of tempered glass, which is nice. I dropped one from the counter to the floor and it shattered. However, the fragments weren't too terribly sharp. I missed sweeping up one piece in my kitchen, which was later stuck to the bottom of my sock. I walked around for about an hour without any injury, and was kind of stupidly thinking, "wow, it feels like there's something hard stuck to the bottom of my foot." Not one of my greater moments...

These pipettes are not accurate and difficult to use. I would not suggest purchasing these unless accurately is totally unnecessary. I would have returned but accidentally broke one when installing cheap rubber cap. Oh, and they leak exeessvly as well. Might be good for an elementary school project but nothing more.

i use these for making ink from mushrooms. Works fantastic. I also use it for making soaps handling essential oils. The long large size is great for long tall bottles or for shaggy mane mushrooms

These things are great! They make filling 5 and 10 mil dropper bottles easy. The contents does slowly drip out after you draw it up, but if you organize your space with the bottles right next to the liquid you are drawing up, there's really not a problem. I like the cleaning brushes they come with, too. Great buy!
