Mudder 200 Pieces 0.2 ml Capacity Disposable Graduated Transfer Pipettes Dropper Polyethylene

Very pleased with these Mudder Disposable Pipettes. Mudder 200 Pieces 0.2 ml Capacity Disposable Graduated Transfer Pipettes Dropper Polyethylene I purchased these strictly for use with my essential oils. They work particularly well for removing denser oils from smaller bottles. Oils like Vetiver, Amyris, and Angelica Root. These pipettes absolutely DO FIT INTO the center of the any standard ORIFICE REDUCER. Having said that, THEY DO NOT, HOWEVER, GO COMPLETELY THROUGH. No pipette is able to do this. This is due to the design of the standard orifice reducers themselves. As far as pipettes go, when it comes to transferring essential oils, these are the best that I found, to date.💢 The same design that allows the oil to drop through, without just pouring straight out, is the same design that prevents a pipette, or any object, from passing completely through it to the other side. These pipettes are, by far, the best that I have found to date.➕ If you have a spare orifice reducer, or one from an empty bottle, turn it upside down, and you will notice that the center hole from the top-side does not go all the way through the underside. At first glance it may look as though the bottom of the orifice reducer is completely closed off, like there is no way for the oil to enter the reducer. But, if you look carefully you will see either a few tiny holes, or a tiny little plastic criss-cross on the underside of the reducer. The oil passes through these tiny holes, or criss-cross, and then drops out through the top of the reducer. Because the path through the reducer is blocked on the underside, sans for these tiny holes or criss-cross, there is no way for a pipette to pass completely through the orifice reducer to the other side. It will go in until it hits that end point, but that's it. It is necessary to tip the bottle some, so that the oil can make contact with the pipette.✔️ SHORTER, FINER, PIPETTE TRANSLATES INTO LESS OIL BEING LOST IN THE TRANSFER: One advantage to these droppers is their size. Because the tip is fine and pipette itself is short, less oil is being drawn up, and less oil is left behind coating the inside of the dropper. This translates into less oil being lost in the transfer. With a long pipette, and/or one with a larger capacity, there is more oil left behind, lost in the transfer.These easily draw the oil up into the bulb portion of the pipette, even the denser oils like Myrh, Vetiver, Angelica Root and Amyris. I have a tool that easily removes the orifice reducers, but having finally found pipettes that fit, I no longer need to. Some of the denser oils are just too "thick" to drop through any orifice reducer at all. It is for these oils in particular that I purchase these pipettes. There are also times when I am working on a new blend and want to be more precise with the amount drops I am adding, and these are perfect for that.✿ FITS INTO THE CENTER OF ANY STANDARD ORIFICE REDUCER:These will fit into the center of any 5ml, 10ml, 15ml, or 1 ounce bottle which has a standard orifice reducer. I use these with all my oils, doTERRA, Young Living, Simply Earth, Rocky Mountain, and Plant Therapy essential oil bottles. It is NOT necessary to remove the orifice reducer.✿ DRAWS EVEN THE DENSER OILS: Even the denser oils, those that will not drop through the orifice reducer at all, I have no trouble drawing into these pipettes.✿ BLENDS: I uses these when I am working on a blend and need to be precise with the number of drops I am working with.✳️ THESE COME PACKAGED AS TWO SEALED PACKS - EACH PACK CONTAINS 100 PIPETTES IN EACH.*️⃣ OVERALL: Overall, I am really pleased with these, they serve my purpose well. I purchased several types that were too large to fit into the orifice reducers at all, so am pleased to have found these that do. If you have any question leave them in the comments and I will be happy to answer.

I use these pipettes for cyanoacrylate adhesives. The high quality ones come in bottles and dispensing directly from them is a really bad idea. These small pipettes are the solution, each use is a precision delivery of adhesive where it needs to go and without risking an adhesive bottle spill accident. If you have leftover inside the pipettes, you can squirt it right back into the bottle. I usually discard the used pipettes, but it may be possible to reuse them. Highly recommend!

I bought these to use with my home hemoglobin & hematocrit monitor due to anemia & they work very well & are eady to use. They are very cost effective. Can be used with any monitor that must have blood to test.

I like the small size of these pipettes to get essential oils out of the bottle without removing the orifice reduced (you have to tip the bottle, but I had zero spillage). I was making sample 2 ml roller balls and know that the conversion is typically 20 drops per 1 ml, however, 40 drops from these pipettes didn't even fill the bottle half way. I counted 120 drops of fractionated coconut oil to fill a 2 ml glass bottle to the shoulder. Knowing this, I was able to calculate the appropriate dilution of the essential oils so that the blends were the correct proportion using this same size pipettes to measure everything. Ideally it would have a ballpark drop per ml listed, or at least point out that the finer tip of the pipettes would result in smaller drops - that is the only reason for the 4 stars instead of 5.

They work great

I have noticed that a few of these are plugged. It's a huge inconvenience in the middle of a project. Still a decent value though.

So I accidentally ordered these thinking they were the larger size. However I have switched to these almost completely.Pro’s- These produce 1/5 of the plastic waste the larger ones do. It feels like such a waste drawing 5 drops of oil and throwing something away. I use glass too, but they are a nightmare to clean, and use tons of water to thoroughly rinse-These are great for drawing oils from bottles with orifice. I don’t have to remove dropper.-They will give you more precise drops. Pure alcohol drop weighs about .010 gram. Depending on the oil .012 - .017 grams per drop. The larger are close to double that. Good to keep on hand for remaking batches and getting closer to original weight.Con’s-Suction not as good as glass or the better quality plastic.-Depending on medium they don’t last. Alcohol, citruses will degrade these. Might not work for higher grade solvent materials.-You’ll need to keep some larger ones on hand for larger bottles to reach material. Also for larger amounts. It takes a lifetime to fill anything larger than 5-10ml.Definitely worth having some of these on hand.

Easy to use works well. great product. I have not found any defective ones and would be willing to buy again when I run out of these.
