<div class="moz-cite-prefix">Agree with Erik- this is the easiest
and most time efficient way. Would be careful with too much
underpressure in historic stopper jars, because negative pressure
puts strong physical stress especially on the glass neck of
stoppered jars. Would do this only with industry lids.<br>
<br>
Even then, pickle jars with large opening diameters (> 10 cm)
are difficult to open if the underpressure is too high; you would
then have to lift the lid with a knife or similar to release the
underpressure - and in doing so - scratch the lid (which will then
starts rusting).<br>

All the best<br>

jars with gaskets etc. etc.. Through keeping the temperature

research and discussion whit lots of museum taxidermist
colleagues if come to the conclusion that the best sealed
jar is one with negative pressure, like marmalade jar. The
negative pressure can be reached in an desiccator or a
foodsealing machine. We are trying here at the museum to get
a big vacuum-chamber to pressurize lots of jars at the same

We have metal lids since the 1990ies in our collection. At
the moment, I occasionally have to replace those which
have and additional PE foil originally thought and
introduced to improve the closure. In fact it traps
condensates and accelerates deterioration (rusting ) of
lids.<br>
<br>
As we have huge troubles with our climate control systems
since several years (system dates back to 1985 and never
worked properly, leading to RH shift btw. 80-30 %,
yesterday I was even below 30% ..) and temperature shifts
ranging from 16-24�C, metal lids in our collection are all
but under stable, controlled conditions. Adding to this,
we have the quite aggressive ketone MEK as denaturant.
Still, the metal lids do fine, and our observations in
Munich largely agree with observations Emily Dock made in
Stockholm. (</span><span

production standards between North America and Europe ? I
know the Steigerwald & Laframboise paper, but the
question of taping all jars (and re-doing all taping once
the jars are opened) is a simple cost-benefit question: a
metal lid is less then 10 cent and replacing a lid is less
then 5 seconds, re-doing the taping takes 1-2 minutes plus
tape costs. We have a rather small, but heavily frequented
collection, so replacing metal lids is the cheaper option
for us.<br>
<br>
My observation is that PP-lids with PE-liners do fine up
to 45 mm neck opening. Above that (50 mm), closures are
not that good and jars show increased evaporation issues.
So our strategy at the moment is: PP-lids with PE-Liners
for 100ml-300 ml jars (rarely 500-1000 with 50 mmm necks),
1200-1700 ml jars with metal lids and above only
borosilicate with plane or ground stopper closures
(typical sizes are 300 mm x 80 mm and 300 x 150 mm for
flanged and 400 x 150 mm & 600 x 200 mm for
stoppered).
<br>
<br>
Mike's question was to replace metal lids for jars which
were designed for metal lids. Because of the narrow
threads of those jars and the fact that opening would be
rather wide (if I understood Mike's question correctly), I
doubt that PP-screw on lids for diameters above 50 mm
would be a could replacement. Independent of this I
definitely agree that replacement of entire jars
(compromised metal lids in jars with necks up to 50 mm in
diameter) with jars with PP-lids would be a good idea.
Depending on the climatic conditions inside storage. PP
lids with PE liners are surely a much better oxygen
barrier compared to PVC.-lids, but still allow diffusion
of oxygen. Metal lids have a better performance in this
regard.<br>
<br>
In the end there are several trade-offs and no straight
forwards solution, I guess.<br>
<br>
All the best<br>

<p class="MsoNormal"><span lang="DE-CH">Dear Mike,<br>
<br>
depending on the climatic conditions inside you storage
area and the holding fluid the specimens are stored in
rusting of lids can be a major issue of course. However,
because of the narrow thread of twist-off jars, I am not
entirely sure of the metal lids can be easily replaced
with plastic lids. The latter usually need higher
threads because plastic lids tend to be deformed when
screwed tight. This is the reason why jars with plastic
lids normally have two fully closed thread turns,
compared to jars with metal lids which usually only have
half thread turns. <br>
<br>
Moreover, plastic lids (e.g. PE or PP lids) do not form
a good barrier against oxygen, and changing lids might
increase or trigger oxidation issues inside jars.<br>
<br>
My advice would be to look into modern metal lids
designed for food industry to close jars with sour
ingredients (compared to lids for sweet stuff such as
jam or honey); these usually have thicker liners inside
which protect lids against scratching. Also made bad
experiences with (self-designed) PE-foil inlays, an
earlier curator introduced in our collection: the foil
is no good barrier against compounds evaporation from
holding fluids, but a perfect trap to hold condensates
inside a tiny, highly corrosive atmosphere lid and foil
which tends to accelerate deterioration of metal lids. <br>
<br>
Might be worth to check in the food sector for
replacement lids or inquire such suppliers where to find
130mm lids.<br>
<br>
All the best<br>
