Well I have no where else to look. I have tried various websites stores etc. I have looked into various sources sites extensively. And so far everything is just a source of aggravation. I can find all of the various parts but its over priced and takes to much searching to find parts. I just wanted to know if any one has a site that does laboratory orders so that I could order all the parts that I will need for a long time. The type of order a lab would make. Within a 4000< the cheaper the better. Thanks!
