Glass laboratory bottles with DIN thread to ISO 4796. Safety-coated in plastic (DURAN® Protect). Neutral glass / Type I acc. to USP/EP. With Retrace code (Batch identification). Certificate available via the Internet.
DURAN® Protect is a resistant and transparent plastic coating based on a cross-linked co-polymer (polyurethane) applied onto DURAN® 3.3 borosilicate glass. The coating made from PU adheres to the glass surface and fulfils the following functions: - protects the glass surfaces against mechanical damage (scratch protection) - keeps fragments together in the event of glass breakage (shatter protection) - minimises loss of fluid in the event of glass breakage (leak and spray protection) - absorbs UV rays up to a light wavelength of 380 nm (light protection) Temperature resistance Do not subject to an open flame or direct heat (e.g. on a laboratory hotplate). The max. temperature sustained is 135°C - continuous use at this temperature (>30 mins.) should be avoided. DURAN® Protect is suitable for freezing (down to -30°C) and for use in microwaves. Please order cap and pouring ring separately. Capacity 2000 ml Ext. diam. 136 mm Height 260 mm Neck thread 45 GL
