mox, you high for sure 
a screw-on lid suffer from the limitation that you need a good grip on the lid to close it off well and most of these lids are made from soft aluminum, and this gives in over time if tightened to the limit. so a bit high like you been or rheumatism or similar issue and you won't be able to close these up.
not so with clamp ones, everyone can get them close, there is always a way. they seal tight and the do so over time too. thats the reason why this jar type is still often used in labs |
HOLY FUCKING SHIT, ...i just read this thread now and i couldnt believe it when i saw my post, i dont even remember typing it. For a split second i thought someone was hijacking my account lol. I was pretty fucking drunk last night, im not going to go on my computer anymore when im drunk...very scary
But still, i stand by my thread. Those clamp seals dont really tighten as much as the masons, not to mention that they cost a shitload and have an awkward shape for storage. Also, with masons you have the option of using a pump sealer thingy to increase the pressure...i cant remember where to buy them , but they're around.
