The proSET A series are thermostatically controlled double jacketed vessels manufactured from high quality borosilicate glass with dish shaped bases. The headplates are constructed in stainless steel, with all wetted parts at 316L grade. The A series has excellent temperature uniformity across the vessel, making it particularly suitable for temperature sensitive cell types. The dish base can be combined with pitched blade style impellers to give an excellent system for cultivating shear-stress sensitive cells. The vessels range from 0.5 ml to 10 L maximum working volume.
