SEOH Plastic Hexagonal Weigh Boats Micro Dish 100pk

The perfect little thing for you to use to hold your smallest amounts without spilling it. I use it to measure out an oz of sugar or anything of that substance with out it spilling and getting all over my hands. You can place what your measuring in it and if your not ready to put it in your recipe then it will hold it just fine until your ready. Bottom is flat. They are also bendable so you can bend it outward and it comes out of one of the slants evenly without spilling. I rather use the hexagonal weigh boats than a sauce cup or something like that. Very easy to handle and it's precise.

I bought these for an unconventional reason, so I'll talk about that, but I wanted this review to be useful for people who wanted to use these as weighing boats, as well, so I'll also offer some comments regarding that use. I recently got a set of nail art brushes. These are items that won't fit down into traditional nail polish bottles. So I needed little trays, preferably something disposable, to pour a bit of polish out into so I could use the nail art brushes. Since I spent six years in chemistry graduate school, plastic weighing boats immediately came to mind. These were the smallest ones I could find, which meant I would be wasting the least amount of polish possible. And they definitely work for that purpose. They're big enough to move a nail fan brush around in, but they also work for just dotting tools. You can use a separate one for each color and throw them away afterwards (yay for a no-mess cleanup). In a similar vein, you could probably also use these for mixing small amounts of paint. These also work for weighing small amounts of substances (I checked, using stuff like flour and sugar I found in my kitchen). They would really only be suitable for microscale synthesis experiments or maybe preparing solutions of standards for liquid chromatography or a similar analytical method because the bottoms are only a little bigger in area than a US quarter. They are made of a material with the same finish as practically every other weighing boat I've ever used. They're pretty lightweight, but that's really what you want in a weighing boat.

If you're wanting cheap little weighing boats then these perfectly fit your requirements. I wanted these as a substitute to the included weighing pan with the American Weigh Scales GEMINI-20 Portable MilliGram Scale, 20 by 0.001 G as they provide substantially larger surface area, depth, & volume. If you're able to reuse the same boat over & over this will probably last you forever for just $6 I was curious though on how consistent the weight of these boats are from boat to boat. Testing repeatability of my scale I placed the exact same boat in the exact same place and repeatability was fairly good only varying around ~.003 grams. Making this more difficult though is that the boats are not symmetrical as the width of the edges clearly vary. My method to test their weight consistency was to take a stack of boats and put them all in the same orientation - wide edge to wide edge / thin edge to thin edge. Then I would place a single boat on the scale, let it settle, remove it let it rest to zero and then repeat. I did this for about a dozen boats. Every 3 or 4 boats i would pull an earlier one to see if it still measured within .003 grams of its original weight and they all did. I ended up finding a variation from .460 grams to .550 grams. Depending on what you are measuring this is a fairly huge variance. So you do not want to tare 1 boat once and then measure multiple different boats already loaded. Tare each fresh boat before loading.

I'm getting into craft cocktails and needed these to do measurements properly for various powders like citric acid and agar agar in very small amounts. I use it with this scale: American Weigh Scales GEMINI-20 Portable MilliGram Scale, 20 by 0.001 G and it works. These do fit in the small weighing dish (which is a pain to clean if used by itself) but it's a little clunky. You can wash these and dry them (not in the dishwasher). Although they are cheap enough and come with enough.

Uneven shape, some edges longer than others. Tiny pieces (slivers/needles/shards?) of plastic in between each weigh boat? No thanks... I don't need. This is a MASS produced product made with low low low quality plastic. Quality control non-existent. These look *like* actual weigh boats, but they are thin thin thin "plastic" and should not be used for ANYTHING. Not safe. There is plastic coming off of the plastic. You will contaminate your sample of whatever it is you are trying to weigh with excess plastic. Do. Not. Buy. SEOH

Great product, wasn't what I was looking for. I was needing a smaller tray for powders and fine products. Would be very good for herbs, spices, or anything along those lines also many many many things just not what I thought. Great communication and shipping from seller. I was sold on the thought I wouldn't lose very much if any product but I lost more then expected. That's my expectations though, not anyone else's. Don't let this review not buy. Not a cheap product whatsoever. sturdy and not easy to destroy.

The "micro" dish is listed has having a capacity of 20ml, but I measured it to be less than 8ml. In practice I can comfortably get only about a teaspoon (5ml) of powder in it (around 3g of most powders I've tried), and I judged it to be full with less than 8g of tap water in it. Some powders slide right off the surface, but some powders cling. Of the clingy powders I've tried, I can say they cling a lot less to these dishes than they do to my metal spoons. Otherwise they are sturdy and, for my needs, quite reusable.
