DWK LIFE SCIENCES Kimble RAY-SORB Volumetric Flasks with PTFE Stoppers

• Flasks are RAY-SORB processed to protect materials sensitive to the light of shorter wavelengths for less than 1% transmission below 400 nm and approximately 5% transmission at 400-600 nm
• PTFE standard taper stoppers provide excellent chemical resistance while the heavy, uniform walls offer superior strength and durability
• Flat interior bottoms allow for stirring with standard stir bars and large, permanent, easy-to-read markings offer quick identification
• These flasks are graduated to Class A volumetric tolerances for wide-mouth flasks while the wide mouths allow easy pipet access
• Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements and then RAY-SORB processed
