It might aversively affect the morphology of the tissues (leak cell membranes / shrinkage). The formation of air bubbles is mostly related to the thermodynamic process of mixing when a specimen is subjected or transferred to a fluid with a different composition or concentration. Vacuum can also lead to boiling of the fluid once its vapor pressure is reached. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-family:"Calibri",sans-serif'>Kind regards,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-family:"Calibri",sans-serif'>Dries<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:black;mso-ligatures:none'>--<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:black;mso-ligatures:none'>Andries J. van Dam (director)<br><br>Alcomon Company<br>Leliestraat 54<br>2313BH Leiden<br>Netherlands<br><br>Tel: +31615676299<br>E-mail: <u><a href="mailto:ajvandam@alcomon.com"><span style='color:#0563C1'>ajvandam@alcomon.com</span></a> <br></u>Website: <u><a href="http://www.alcomon.com/"><span style='color:#0563C1'>http://www.alcomon.com</span></a><o:p></o:p></u></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;mso-ligatures:none'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;mso-ligatures:none;mso-fareast-language:NL'><img border=0 width=181 height=41 style='width:1.8854in;height:.427in' id="Afbeelding_x0020_4" src="file:////Users/ajvandam/Library/Containers/com.microsoft.Outlook/Data/Library/Caches/Signatures/signature_4024095363" alt=AlcomonLogo></span><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-AU style='font-family:"Calibri",sans-serif;color:black;mso-ligatures:none;mso-fareast-language:NL'>Van: </span></b><span lang=EN-AU style='font-family:"Calibri",sans-serif;color:black;mso-ligatures:none;mso-fareast-language:NL'>Nhcoll-l <nhcoll-l-bounces@mailman.yale.edu> namens "Haff, Tonya (NCMI, Black Mountain)" <Tonya.Haff@csiro.au><br><b>Datum: </b>woensdag 7 mei 2025 om 06:02<br><b>Aan: </b>"NHCOLL (nhcoll-l@mailman.yale.edu)" <nhcoll-l@mailman.yale.edu><br><b>Onderwerp: </b>[Nhcoll-l] Vacuum jars and pumps<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-AU style='mso-ligatures:none;mso-fareast-language:NL'><o:p> </o:p></span></p></div><p class=MsoNormal><span lang=EN-AU>Hello all,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-AU>I am wondering if any of you have recommendations on vacuum jars, either in terms of styles, brands, or sizes? I’m being inspired by Simon Moore to think we would benefit from being able to remove air bubbles from wet specimens during the preparation process (or rehydration process when I get the time for that). If you also have recommendations for vacuum pumps I would also be very interested as well. Thoughts and caveats also always appreciated.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-AU>Thanks!<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-AU>Tonya<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-AU'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-AU'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-AU'>------------------------------------------------------------------------<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-AU'>Dr Tonya Haff<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-AU'>Senior Collection Manager<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-AU'>Australian National Wildlife Collection<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-AU'>National Research Collections Australia, CSIRO<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-AU'>Canberra, ACT 2602 Australia<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-AU'>+61(0)419569109<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-ligatures:none;mso-fareast-language:NL'>_______________________________________________ Nhcoll-l mailing list Nhcoll-l@mailman.yale.edu https://mailman.yale.edu/mailman/listinfo/nhcoll-l _______________________________________________ NHCOLL-L is brought to you by the Society for the Preservation of Natural History Collections (SPNHC), an international society whose mission is to improve the preservation, conservation and management of natural history collections to ensure their continuing value to society.
