It seems something is not quite right with the markings. I checked them with distilled water and they do not make sense. The marks on both of these appear to have been drawn using a height gauge or something similar, and I think that's okay. My problem lies in the fact that both appear to be more than one inch out of specification. You need 5mL of each solution There is one more thing I need to add. There is a 5mL overflow to get a full 500 grams, so technically the flask is overfilled The full version. Using a non-metal straw I applied the 500mL level to the neck and confirmed it using a non-metal straw The electronic triple-decker I have validated in two different directions with a beam balance and I also got the same results. This confirms the result of two different balances, showing that the markings are incorrect. My first case used the Ohaus SPX2202 and I filled it with 500 grams of water. As I wrote on the neck earlier, this corresponded with the mark I made. Next, I added 250 grams twice more to get to 500 grams, then poured the contents of the flask into a beaker on my Ohaus 700 series triple beam balance. Neither balance is different from the The labels on both flasks appear to be incorrect. The markings on the cards can still be used, but I can't trust them until I figure out why they aren't working. There seems to be less gravity in this area? We will follow it closely and post another update if an explanation comes up. Here's the update It's not helping either that I also checked it with another electronic balance, and the factory marking was still wrong. If you are keeping score, that's 3 different balances (one of them calibrated) and all of them indicate that these are outside Karter Scientific products have never caused this kind of problem for me in the past.
During manufacturing, the product had some type of resin or adhesive on/around the neck fill line and stopper as well, and in the opening of the flask, where the stopper should be, there are three voids where there should be none, accounting for the poor sealing. Paying a price for something ensures a quality outcome.
It is not fit to be used in a laboratory. In my opinion, this isn't a legitimate source of information. The chances of it being a foreclosure are extremely high. There is no way Karcher Scientific would send junk mail This is NOT something to boil in. Though I haven't tried it yet, it looks like I can blow this flask on my own after a week of practice. Trying to blow glass for the very first time. Having a Halloween party set up would be a good price for this setup. Depending on the brand and quality, volumetric flasks with a ground stopper cost $20 and above.
This flask is nice and perfectly acceptable to me. It was bottom-ranked because the results could have been improved if the grind residue in the stopper hole had been cleaned out more thoroughly. A new acid is on the horizon for me Washing it is a great idea, but volumetrics are more difficult to clean when they are Whenever I have leftover residue from them, I NEVER let them dry out. Therefore, I always store them full of DI water. I would have been much happier if I could have started fresh with a For the price, though, it is a very good flask. Since I intend to purchase another one from this manufacturer in the future, it is a very good purchase.
It arrived scratched and is too thin. When the previous one broke, the water just poured out of it as it fell over on its side full of water on a wood surface, not even on It isn't worth my time to return it, but you should note that LabGlass makes better products.
The flasks were both weighed on a calibrated scale and were both within the range their manufacturers have stated they are accurate at +/- There are 1 mL in the tube. Fittings for the glass stoppers in the flasks hold water well. This is a very good.
One bottle had a resin ring around the neck, which tended to indicate that it was used. Despite being a smaller size (250mL) of the product, it was very clean and packaged nicely. The 500mL version of this bottle came with a ring of resin around the neck, which needed to be removed using polar protic solvent. There was some left over and it was pretty hard to remove. I used a little bit. It will take 5mL of homemade Pirhanna solution (Caro's Solution) to thoroughly remove all traces. I am not sure what it was, but it must have been loaded with aromatics since it reacted hot. *There are no major issues with the product, and it is very durable and well made.
Its neck is almost too skinny because they forgot to put a cap on it.
