DURAN® PROTECT coated Borosilicate glass 3.3, clear, with or without screw cap.

• Very good chemical resistance and good heat resistance (max. thermal load 135 °C), constant loads longer than 30 mins should be avoided
• Minimal thermal expansion, giving relatively high resistance to temperature changes
• Compressive strength is not increased by the plastic coating
• Glass Type I according to USP, EP and JP

Round, with graduation and DIN thread. Without pouring ring or screw cap. The coating provides protection against mechanical damage (scratches, etc) and serves as spill and spray protection in case of breakage. It also prevents pieces of glass from shattering.

With printed Retrace Code (batch identification).

*With specially shaped glass rim for improved pouring; no additional pouring ring is needed.

**Ring-shaped reinforcement on the bottle shoulder makes the filling line of the nominal volume visible.
