<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Something is expanding in those vials to cause the “explosion”. What temperature is your preservation fluid at? Could it be that you are adding “cold” preservative that is then expanding
as it heats up to room temperature. One thing you may consider is leaving vials unclosed for a short period of time to allow for the fluid temperature to equilibrate before sealing.<o:p></o:p></span></p>

<p><span style="font-size:10.0pt;font-family:Tahoma;color:black">We are having some problems with our glass vials (2-dram, 4-dram, and 6-dram) cracking, breaking, and in some cases exploding. In one instance the top of the vial snapped and shot up a few inches
in the air about 5 minutes after sealing the vial (very exciting). However, most vials that break are found during routine (monthly) checks. In some cases, the vials have been fine for a year, and then will break. In other cases, they break a week or two after
fillign. Breakage occurs several ways: a clean break along the neck, a clean break along the bottom, or spider cracks along the whole vial. Has anyone else had this problem or know of a solution (e.g., do we need higher quality glass vials, are we screwing
down the lids too tight, etc.)?<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:Tahoma;color:black"> <o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:Tahoma;color:black">We use Kimble™ Screw-Thread N-51A Borosilicate Glass Sample Vials with Closed-Top Black Phenolic Caps with Rubber Liners. Vials are filled with ethanol (either 70% or 95%) and larval fishes. Vials
are stored in cardboard vial trays with dividers between vials, and vial trays are stored in wooden drawers in sealed metal cabinets. The room has minimal fluctuations in humidity, but can fluctuate in temperature by about 5 degrees. Once the vials are stored
they are relatively undisturbed, so there is little to no bumping or moving of the vials.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:Tahoma;color:black"> <o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:Tahoma;color:black">Any thoughts or recommendations of other vial manufacturers would be appreciated.<o:p></o:p></span></p>
