<p class="MsoNormal" style="text-autospace:none"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">Always keep in mind that collections are also there to be studied/used and periodically should be monitored/cleaned/topped up, etc., and that
therefore not only the storage conditions but also the use conditions are taken into account when setting up the climate parameters for your storage facility.
<o:p></o:p></span></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">For fluid preserved collections, CONSTANT ambient temperature is preferred above lower temperatures (e.g. below flashpoint). John Simmons already
mentioned several arguments for this recommendation. The more climate control is dependent on heavy heating/cooling equipment (passive/preventive measurements to building would be far more sensible), the more chance (instant) problems will arise when it temporarily
fails.<o:p></o:p></span></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">When a fluid preserved collection is stored below the flashpoint of ethanol, and a user of the collection takes a selection to the laboratory
(where temperature is </span><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">likely 10 degrees higher) and vice versa, it can lead to problems that can seriously affect (shock) the condition of the specimen, fluid, container, and lid/seal.
More info on how temperature affects “</span><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";mso-fareast-language:EN-US">The Interactions of Preservative Fluid, Specimen Container, and Sealant in a Fluid Collection”</span><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">It is highly recommended to seperately store fluid collections and dry collections, for many obvious reasons (RH is far more critical for dry collections, acid vapours of
formalin, spill accidents, etc.). Also, it is advisable to seperate flammable and non-flammable fluid collections. For the latter, less costs have to be made to comply to safety regulations (no fire hazard).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">Hope that this together with the recommendations and suggestions of my peers, will help you in realizing the best conditions for your collections.<o:p></o:p></span></p>
