Introduction
BIOBASE BK-UP series ultrapure water purifiers deliver laboratory-grade ultrapure water with resistivity up to 18.1 MΩ·cm (@25°C). They are designed for critical workflows such as molecular biology, cell culture, analytical chemistry and instrument feed.

Features

• Three-point water quality monitoring (feed water, RO water, UP water) with consumable life alarms.
• 5-inch LCD for real-time status and parameters.
• Scheduled water dispense function for routine processes.
• High/low pressure protection and automatic shutdown on water loss.
• Automatic start-up flushing to extend filter element life.
• Optional pressurized water output to suit different application needs.
