Supporting device for reaction vessels.
DURAN® Baffled Flask. With GL 45. With 4 bottom baffles. Complete with membrane screw cap and pouring ring. • Oxygen introduction is often a limiting factor for cell growth. • Baffled flasks cause a turbulent flow, increase the gas exchange surface and produce a higher oxygen transfer. • Automated one-step production enables a reproducible and comparable result.
PP Tamper-evident screw caps for Laboratory bottles with DIN thread. With lip seal. Temperature resistance: max. +140°C. The integral plastic ring tears when the cap is first opened and is retained on the bottle neck. Therefore it can be clearly seen whether the bottle retains its original seal. After first untwisting, can be used as "normal" screw cap.
