Beckman Fp, Flow Check Kit Coulter Fluorospheres 3 X 10 Ml Kit

Beckman flow-check fluorospheres consist of 10 μm (nominal diameter) polystyrene fluorescent microspheres suspended in an aqueous medium containing surfactants and preservatives at 1 x 106 fluorospheres/ml (nominal concentration). the fluorescence emission of the dye contained within the fluorospheres ranges from 525 nm to 700 nm when excited at 488 nm. flow-check fluorospheres are used to verify instrument optical alignment and fluidics. - BKMPFZ (Additional S&H Or Hazmat Fees May Apply)
