FAQ

5-inch color touchscreen; built-in storage can store one year’s worth of operation, water intake, and alarm records; USB export to Excel; complies with GLP and laboratory audit requirements.

It has two-level access passwords, separate for users and administrators, restricting unauthorized modification of water quality, consumables, and rinsing parameters.

3 water quality sensors (raw water/RO water/UP ultrapure water) + 2 flow sensors; ECO only monitors a single water quality channel, while Master provides real-time monitoring of all three water quality levels.

S/Q models connect to tap water; D series models connect only to distilled water/purchased pure water, requiring no pretreatment, suitable for mass spectrometry and high-end molecular experiments.

The D series does not have a tap water pretreatment filter, eliminating the need for pretreatment consumable replacement, but the influent must be pure water that meets standards, making it suitable for laboratories with existing water purification equipment.

Stable at 18.2 MΩ・cm, meeting ASTM, CAP, CLSI, EP, and USP Class 1 pure water standards.

The UVF model has RNase < 0.01 ng/ml and DNase < 4 pg/ul, fully suitable for PCR, nucleic acid, and protein experiments.

Endotoxin < 0.001 Eu/ml; works with automatic circulation for sterilization throughout the entire system.

It features UP water circulation throughout the system to maintain high resistivity; supports one-button sterilization of the entire system’s piping.

The flushing interval and duration can be freely set, and manual forced flushing is also possible.
