<div dir="ltr">Thanks for mentioning Menda! Their catalog (<a href="https://menda.descoindustries.com/">https://menda.descoindustries.com/</a>) is really impressive. I've also had the same problems as Jean-Pierre with cheap pump bottles (poor seal, deformed neck/threading, tube split or cut poorly, pump broken on arrival), and they're one of those things that are so cheap I've never considered how much better a name brand would be. Kind of easy to forget these are a tool. Spending $25+ (4-5x more) for a better tool is not too expensive for the quality of life improvement from getting rid of those annoyances. <div><br></div><div>Good useful thread. As usual, Roman has the most practical advice. There are still plenty of reused jam jars full of mysterious liquids here. :)</div><div><br></div><div>Nathan</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Wed, Jan 28, 2026 at 4:26 PM Jimmy Moore via Synth-diy <<a href="mailto:synth-diy@synth-diy.org">synth-diy@synth-diy.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">I'm used to seeing these described as menda bottles.
