The University of Manitoba Glass Shop is run by Lesa Cafferty, a scientific glassblower with over 25 years experience in the field. Growing up in a household where glass blowing was a way of life, as her father James Cafferty was a Scientific Glassblower working at Atomic Energy of Canada Ltd. He was also an artist in glass who made and sold numerous types of glass figurines.  Each day, he would go into the shop at home, sit at the bench with a burner and do a little bit of glassblowing during Lesa’s childhood.  Lesa’s early exposure to the art and developing the glass handling technique from a very young age.  She took on an apprenticeship under her father at Atomic Energy of Canada in April 1992-1996 and later became his successor when he retired.  In August 2006, Lesa relocated to the University of Manitoba where she continues to expand her knowledge as a scientific glassblower, providing clients with knowledge and expertise, and quality glassware for their specific work needs.



With a large inventory of different sizes of Pyrex tubing, along with ground glass joints and all varieties of stopcocks from Teflon to hi-vacuum, graded seals, Kovar seals and quartz glass, the product is available for many types of glassware required.  Any special items required will be ordered to accommodate the client’s requests.
