Specifications:
The document outlines the specifications for three models of HPLC Bio water systems: CB-1901, CB-1903, and CB-1905. All models produce Grade I water with a resistivity of 18.2 MΩ x cm and conductivity of 0.055 µS/cm at 25°C. The Total Organic Carbon (TOC) levels are <10 ppb for CB-1901 and <5 ppb for CB-1903 and CB-1905. RNase and DNase levels are specified only for CB-1905, with <1 pg/mL and <5 pg/mL respectively. Bacteria levels are <0.01 CFU/mL, and endotoxins are <0.15 EU/mL for CB-1901 and CB-1903, and <0.001 EU/mL for CB-1905. Particle count for particles >0.22 μm is <1/mL for CB-1901 and CB-1903, and <0.05/mL for CB-1905. The dispense rate for ultrapure water is <1.5 L/min across all models.

Display and Dispenser:
All models feature a colour LCD display and a dispense port. TOC monitoring is available in CB-1903 and CB-1905.

Environmental Conditions:
The systems operate within a temperature range of 15–30°C and relative humidity of 20–80%. They require a mains voltage of 200–240 VAC and consume 130 W of power.

Physical Dimensions:
The dimensions for all models are 30*44*64 cm. The system weight is 16 kg for CB-1901 and 17 kg for CB-1903 and CB-1905, with operating weights of 21 kg and 22 kg respectively.

Feedwater Properties:
The systems require pre-treated feedwater with conductivity <100 μS/cm, TOC <50 ppb, temperature between 5–35°C, pH 4–10, and specific limits for iron, aluminium, manganese, CO2, fouling index, total chlorine, and Langelier Saturation Index.

Additional Features:
The Onsite+ water polishing system includes an integrated 5 L tank for pre-treated water.
