Your cart is empty.Karter Scientific Class A Volumetric Flasks are manufactured from high quality inert 3.3 borosilicate glass and meet the tolerances requirements as established by ASTM E-694 - ASTM E-542 - and ASTM E-288. Flat bottom. Volumetric flasks provide improved lab convenience, broad selection and precise volume measurement. Accuracy limits conforms to ISO 1042 Laboratory Glassware-One mark volumetric flasks. With one permanent circular mark. Printed with fused-on enamel color, resistant to most acid and alkaline solutions. Calibration is based on the poured in volume ("In") at a +20°C reference temperature.

Precision grind on Stopper. Good fit. Stopper handle ample size. Score marks are very accurate. Great for the lab.

I use this to hold my cooking oil in my science kitchen! looks great and for what I use it for, it is perfect. There are a few glass flaws but for the price its amazing.

The quality is good but marking seems to slightly off but a great product for the money.

For actual lab gear its a tad thin and there are a few very minor imperfections, but with the type of use labe wear gets they could cause it to break over time.On to why i bought it: Its very inexpensive for what it is. Higher quality vol flasks can run in to the hundreds. It makes a great 1L storage container for whisky. That's right, I use these as long term whisky storage decanters. Another name for borosilicate glass is pyrex. The stuff is chemically neutral (mostly) and wont leach lead in to your drink. A great gift for the geeky whisky snob out there. Come with its own stopper which is the icing on the cake.

Used a series of chemistry pieces to build a little 'meth lab' on a tray. Used velcro to secure the flasks & beakers to it, and then with colored water & dry ice, it made a cool effect. I put a link to a photo in the comment section; copy & paste it.

This is a cheap flask, and looks cheap. Not a lot of effort to knock the rough corners off the cast glass stopper, poorly inscribed graduation line, appears scratched on rather than etched. It doesn't give me a lot of confidence in the accuracy. I'm going to need to calibrate this before I have any faith that it's even in the ballpark. Three stars, because you get what you pay for.

High quality and useful. A perfect flask for small quantities of mixes and chemicals.

Poor quality. This company does not provide quality lab equipment. It is for the dabbler or drug synthesizer

Lots of defects in the glass (bubbles and such), arrived very dirty. The glass stopper was cut very poorly I could have done a better job myself than whomever did it.Good for demonstrations and such? Likely. Good for analytical chemistry? I'd avoid it.NOTE: AMZ denied my initial wording in my review, for "it broke guidelines"... which it does not. Wording was changed to submit.
