<p class="MsoNormal"><span style="mso-fareast-language:JA">Another problem with “fridge shelving” is that the plastic coating (which is usually not powder coating but hot-dip) can crack and fail in time, especially around welded joints that remain rigid while
the bars bend slightly under the weight of their load. The metal underneath is unprimed mild steel, so it rusts fast.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:JA">Bear in mind too that shelving made of rods does not bear loads evenly; a jar sitting near the edge, for example, will be better supported on one side than the other and will thus lean a bit.

<p class="MsoNormal" style="margin-left:.5in">to me this looks like storage for lab consumables, and even for this purpose you may need to prefer (closed) chemical cabinets instead of open storage (depending on the lab chemicals).<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-left:.5in">For ordinary fluid preserved collections, the recommendation is not to go below 75 ml fluid volume per container. Depending on the quality of the closures and the environmental settings in the storage area, containers
below 75 ml may dry up fast, if the seal/closure is bad. Depending on the number of jars, you would need to adjust your monitoring regime to spot evaporation losses and to prevent damage to objects stored in smaller containers.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in">If you would need or want to store specimens in smaller volumes, it would make more sense to use closed cabinets with drawers. Ideally, as Simon recommends, the drawers are equipped with grids or boxes that stabilise
the small vials or tubes. We have equipped our cool and refrigerated storage with
