Cell Culture Flask T75
Cell Culture Flask surface is very smooth based on precise molding technology and it gives clear view when examined with microscope.
Volume: 25mL75mL175mL225mL
PRODUCT FEATURES
For adherent cell culture: Initial adherence and proliferative property of cells via hydrophilic surface treatment.
For suspension cell culture: The surface is resistant to cell adherence, which minimizes damage or loss of cell.
