Lumiglas exhibited its latest sight-glass and optical solutions at the 67th Qingdao Pharmaceutical Expo. During the show, our sintered sight glass, borosilicate glass, sapphire glass and explosion-proof Lumistar luminaires attracted broad attention and technical enquiries from visitors and procurement teams.
Highlights from our booth
- Sintered sight glass: Engineers praised the product’s durability and clarity for demanding process conditions. Visitors asked about customization for high-temperature and abrasive media.
- Borosilicate glass: Our borosilicate sight windows and tubes received many replacement and OEM inquiries because of their thermal-shock resistance and chemical stability.
- Sapphire glass: The sapphire optics lineup generated interest from high-precision and high-temperature applications, especially in laboratories and analytical equipment.
- Lumistar USL series (explosion-proof luminaires): The USL 07 LED-Ex and related models stood out for their IP65/67 protection and certified Ex ratings. Attendees asked about mounting options for DIN 28120/28121 sight glass fittings.
Why attendees engaged with our products
First, our booth combined product displays with live datasheets and CAD examples. This allowed engineers to verify dimensions, materials and certification quickly. Second, we offered on-site technical consultations that answered application-specific questions on pressure, temperature, and optical transmission. Finally, our team demonstrated installation options for both one-flange and two-flange sight glass + luminaire combinations — a practical detail buyers appreciated.
“The level of technical questions was high — customers wanted concrete data: material grades, AR coatings for fused silica, and Ex certificates for luminaires. We were well-prepared to show those documents.”
Over the three-day event, we logged dozens of qualified leads from pharmaceutical, chemical, and instrumentation sectors. Many visitors requested datasheets, COAs, and CAD files — we have already started follow-up with tailored quotes and drawings. We will publish new application notes and dimension tables on our website to support replacement and OEM enquiries.
