Millipore Sigma RioS Essential 24 Water Purification Tank

• Supplying laboratories with purified water for general tasks such as glassware rinsing, media preparation, and buffer formulation.
• Providing feed water for ultrapure water systems, ensuring their optimal performance and longevity.
• Use in clinical analysers and environmental testing where Type 3 water quality is sufficient.
• Suitable for educational institutions and small-scale research facilities requiring consistent purified water.
• Pre-treatment for humidifiers, autoclaves, and other laboratory equipment requiring a reliable source of purified water.

Typical throughput

For this class of equipment, flow rates commonly range from 10 to 30 litres per hour, providing around 200 to 600 litres per day of Type 3 water.

Water purity

Units of this type typically deliver Type 3 (RO) water, with ionic rejection between 95-99% and high organic/particulate rejection.

Footprint

Compact designs are common, with typical dimensions around 40-50 cm high, 25-35 cm wide, and 30-40 cm deep, making them suitable for benchtop installation.

Power supply

Most units operate on standard single-phase power, typically 100-240 V AC, 50-60 Hz.

Feed water requirements

Units commonly require tap water feed with conductivity below 2,000 µS/cm, pressure between 1-6 bar, and temperatures typically 5-35 °C.

Maintenance

Maintenance for these systems is typically low, primarily involving periodic replacement of pretreatment cartridges and RO membranes, often with smart monitoring features.

Internal features

Commonly found features include integrated pretreatment, high-efficiency RO membranes, and sometimes water recovery loops to minimise waste.

• What is Type 3 water and what is it used for?

  Type 3 water, also known as RO (Reverse Osmosis) water, is purified water suitable for general laboratory applications such as rinsing glassware, preparing non-critical reagents, and feeding ultrapure water systems. It has significantly reduced levels of ions, organics, and particulates compared to tap water.

• How often do the cartridges need to be replaced?

• Can this system be connected to a larger water distribution loop?

• What are the typical installation requirements for this equipment?

• Is this unit suitable for critical applications like cell culture or HPLC?

Pure steam and pure water systems are regarded as critical infrastructure in pharmaceutical and biotech operations. Buyers typically value reliability, compliance with GMP standards, and minimal maintenance history when purchasing used units. Industry sentiment emphasises the importance of verifying system documentation and service records. Common strengths include robust construction, established vendor support networks, and long operational lifespans when properly maintained. Buyers should prioritise systems from reputable manufacturers with clear maintenance histories.
