Services

Ohio State's Glassblowing Facility can meet all of your needs for repair, modification and custom design of scientific borosilicate (Pyrex) or quartz glass apparatus. In addition, the shop can reduce your costs by reproducing standard catalog glassware (many designs on file in our shop library). Our glassblower is the third generation in a family of glassblowers and has been recognized by his peers by being awarded The Andrews Glass Award for best technical paper at The American Scientific Glassblowers Symposium, 1999 (see photo of liquid nitrogen cooled carbon monoxide laser). He is readily available for consultation on intricate design work and can perform on-site repair work in your lab as well as all in-shop services.

Hours: 7:30-4:00 PM Monday through Friday

Note: Please, do not hesitate to call or e-mail with questions about your glassware needs. Drawings of your ideas are not necessary. Set up an appointment to explore the possibilites. A complete estimate to be provided upon request.
