WHEATON Celstir-356873 Double Arm Cell Culture Flask, 25mL, Shinetek Instruments Research Institute (CAT#: STEM-CC-3445-LGZ)

Celstir cell culture flasks contain a height-adjustable paddle blade for better agitation. The bottom of the culture bottle is raised to enhance the effect of stirring and avoid the deposition of cells on the bottom of the bottle.
Celstirs flasks provide a maximum contact area between the culture medium and the gas in the bottle.
Celstirs flasks are suitable for microcarrier and suspension cultures such as insect cells, hybridoma cells, and adapted cell lines. The entire unit can be autoclaved at 121°C for 20 minutes.
Celstirs flasks are made of 33 ultra-low extraction borosilicate glass that meets ASTM Type I, Class A and USP Type I standards.
We can also offer a stainless steel stir bar kit to retrofit your Celstir flasks with perforated caps for 500mL and larger flasks. 125 ~ 1000mL culture flasks have a scale with 50mL as the minimum division; 3000 ~ 8000mL culture flasks have a scale with 500mL as the minimum division; 25mL ~ 50mL culture flasks have no scale.
