带 pH 控制的缓冲液浓缩液稀释站
Weighing salts for every buffer batch invites lot-to-lot drift. This station blends stored concentrate with purified water at 1:10 to 1:40 and checks pH and conductivity before release, trimming with acid or base as needed. Tell us how many concentrates you run so we can fit 2 to 4 reservoirs.
