WebbSeveral different crystallization methods exist. The most common for water-soluble proteins is the method of sitting or hanging drops. For membrane protein crystallization … WebbYou can set humidity on/off manually or “set it and forget it” and let the NT8 do the work. The system has tight control of the humidity with a variance of only +/- 2%. The NT8 Drop Setter can increase humidity from 60% to 85% in under 20 seconds. The humidifiers are positioned away from active samples so your drops are protected from ...
