Some of you might remember me, from a while back??
Besides making and using bio for a few years, I also imported high speed centrifuges directly from the manufacturer, added fitting kits and pumps and sold them on Ebay.
Well, I gave it all in a while ago, but spoke to the manufacturer today (BAPL), who make the best product, dynamically balanced, all sizes including the invert models and will ship with viton seals. Their sales manager Paul is a really nice guy and I asked him if he'd be willing to supply forum members directly - as there are now limited options in the UK to source. I'm guessing by the number of requests that I still get that their are plenty out there who want to centrifuge.
Anyway he'd be happy work on a group buy basis from time to time. If this is of interest to members, could you send me a pm or add to the thread and I can send you Paul's details.
