B300&B310 The B300 is a new integrated Grade 2/Grade 1 laboratory water system, replacing the customer-approved previous B30 model. The B310 is an extended version of the B300, which is designed to produce all types of Grade 2/ Grade 1 and RO laboratory water. The B310 special feature is the ability to produce large volumes of water at low cost for general laboratory applications -glassware washers, autoclaves, rinsing of laboratory materials, etc. A pressurized tank can be added for RO water storage. Both systems have completely new electronics and software, providing several additional features: • large colour touch screen, • data logging capability, • warning and alarm messages, • a wide range of flow control options, • the ability to connect multiple remote dispensers, • dispense report preparation, • improved accuracy of conductivity and TOC measurements. The systems also include RO water recirculation, which reduces tap water consumption.
