<div class="moz-cite-prefix">Hi Esther,</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">vaseline has few disadvantages</div>
<div class="moz-cite-prefix">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)</div>
<div class="moz-cite-prefix">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)</div>
<div class="moz-cite-prefix">3. it sometimes may get backed (might
be linked with low RH values inside storage).</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">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</div>
<div class="moz-cite-prefix"><a class="moz-txt-link-freetext" href="https://www.fishersci.de/shop/products/joint-grease-1/10130201">https://www.fishersci.de/shop/products/joint-grease-1/10130201</a><br>
</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">But you can also contact and order
directly <a class="moz-txt-link-freetext" href="http://www.poellath-labor.de/">http://www.poellath-labor.de/</a><br>
</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">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.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Hope this helps, with best wishes<br>

<div dir="ltr">Dear all,
<div><br>
</div>
<div>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<a
href="https://www.drogisterij.net/verzorging/lichaamsverzorging/lichaamsverzorging-verzorging/creme/vaseline-petroleum-jelly-original-42182634?partnercode=222&gclid=EAIaIQobChMIiOnM3_fx5wIVWeN3Ch1X_wOHEAQYASABEgJTI_D_BwE"
moz-do-not-send="true"> this</a> 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! </div>

<div>Many thanks,</div>
