These pages are meant as an aid to your understanding of our materials and methods. We have included links and information about borosilicate glass in general, tubing and flask sizes and tolerances, connections, stopcocks and valves, fritted glass filters, and considerations about designing glass apparatus. We certainly know more than is listed here; feel free to contact us with any questions.



Please keep in mind that we do not have a catalog. Referencing images in our extensive photo gallery has proven to be very helpful getting to a mutual understanding about specifics. Variation has been the norm.......
