[Nhcoll-l] Question about jar grease in fluid collections

[Esther Dondorp]

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,
