Dear all,
The long-term problem with ground stopper jars is that, due to small temperature fluctuations leading to different expansion-contraction cycles of stopper and jar, the stoppers gradually will sink deeper into the neck of the jar, get stuck, and eventually the neck of the jar might crack. Using a suitable grease (such as soft white paraffin) will at least slow down this process and also prevent fluid to escape by capillary flow between the ground surfaces. When a stopper is already sunk in so far that it cannot be removed, the Universal Stopper Jar Opener produced by Alcomon Company can remove the stopper without the risk of damaging the stopper jar and/or specimen.
Kind regards,
Dries

Grease on ground jar stoppers: Years ago (1960s) my recollection is that ground jar stoppers worked best left uncoated, at least if they were older ones that were ground with some precision. Trouble was usually associated with inadvertent mixing the jars and stoppers such that the fitting was imprecise thereby allowing evaporation (and necesitating some kind of fix). Newer productions may not be fitted with as much precision if not designed for fluid use.

Dear all,
Just a short question - we always use vaseline to seal gound jar stoppers,
now that we cannot use our old supplier anymore the support department
ordered the commercial vaseline petroleum jelly like this
<https://www.drogisterij.net/verzorging/lichaamsverzorging/lichaamsverzorging-verzorging/creme/vaseline-petroleum-jelly-original-42182634?partnercode=222&gclid=EAIaIQobChMIiOnM3_fx5wIVWeN3Ch1X_wOHEAQYASABEgJTI_D_BwE>
one. I was wondering if we can use it or that it has additional additives
that can effect the balance inside the jar. Is there an acid free or other
alternative? Wondering what other people use!
Many thanks,

Hi Esther,
vaseline has few disadvantages
1. it tends to flow inside the jar (especially if you need to close
uneven battery jars etc. with increased amounts of vaseline to produce a
proper seal)
2. it tends to attract additional moisture evaporating from inside the
jar (turning the jelly glossy - usually a good indicator when it slowly
starts running)
3. it sometimes may get backed (might be linked with low RH values
inside storage).
We changed around 2000 to a silicon-free vacuum joint grease called
Alsirol with good results. It is produced from a small company in
Bamberg, Germany and formerly was also distributed (at least in Germany)
via VWR, FisherScientific apparently is also offering it
https://www.fishersci.de/shop/products/joint-grease-1/10130201
But you can also contact and order directly http://www.poellath-labor.de/
The containers are rather small (only 50 ml), but Alsirol is very
economic and you only need little to produce a proper closure (too much
in fact even is disadvantageous). As it is very greasy and stable, it is
possible to build it up on uneven flanges or battery jars.
Hope this helps, with best wishes
Dirk

Thanks Dirk,
I have also had problems with older versions of Vaseline (1970s) where the dehydrating effect of IMS / IDA alcohols produced little tiny coagulated ?pills? of vaseline in the sealed area, whereas Paraffin soft white (a similar product) was fine and didn?t do this. The Alsirol I have used to good effect thus far for at least 7 years but some say it?s quite expensive at E33 per 50ml tub; however, as Dirk suggested, you do only need a thin smear to seal a jar effectively. To that end you only need a small amount of any of the greasy sealants - too much and they gradually flow down into the jar and the lid can ?float? on the excess sealant.
With all good wishes, Simon.

I use vacuum grease, which is more stable than Vaseline and apparently insoluble in ethanol, water or formaldehyde. Dow-Corning make it.

BTW - If you use vacuum grease (what we have used for 40 years) it can be quite difficult to clean off of the glass surfaces should the need arise. For those times when one wishes to clean the jar completely and reseal, I have found mineral oil is helpful, followed by a scrubbing with "Alconox."

Dear all,
Just a short question - we always use vaseline to seal gound jar stoppers, now that we cannot use our old supplier anymore the support department ordered the commercial vaseline petroleum jelly like this<https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.drogisterij.net%2Fverzorging%2Flichaamsverzorging%2Flichaamsverzorging-verzorging%2Fcreme%2Fvaseline-petroleum-jelly-original-42182634%3Fpartnercode%3D222%26gclid%3DEAIaIQobChMIiOnM3_fx5wIVWeN3Ch1X_wOHEAQYASABEgJTI_D_BwE&data=02%7C01%7Ceric.lazo-wasem%40yale.edu%7Ccedc46695e7049889cbb08d7bb9c567d%7Cdd8cbebb21394df8b4114e3e87abeb5c%7C0%7C0%7C637184152457750927&sdata=06C4O4Tx5wzzhuHisssu13B%2B%2BKXc%2Bwcaw279uwj6Qts%3D&reserved=0> one. I was wondering if we can use it or that it has additional additives that can effect the balance inside the jar. Is there an acid free or other alternative? Wondering what other people use!
Many thanks,

BTW - If you use vacuum grease (what we have used for 40 years) it can be quite difficult to clean off of the glass surfaces should the need arise. For those times when one wishes to clean the jar completely and reseal, I have found mineral oil is helpful, followed by a scrubbing with "Alconox."

I use vacuum grease, which is more stable than Vaseline and apparently insoluble in ethanol, water or formaldehyde. Dow-Corning make it.
