PURELAB Prima

The simple and dependable choice for primary grade water

The PURELAB Prima range from ELGA produces primary grade purified water from a potable source in a wide range of volumes for laboratory, medical and industrial applications. Using proven reverse osmosis (RO) technology, the PURELAB Prima is ideal for feeding ultra-pure water systems and for typical laboratory applications including glassware washing, a feed to autoclaves, and for use in environmental cabinets.

Designed to suit your exact needs

PURELAB Prima systems are compact in size and are available in a choice of flow rates to meet your specific needs. The smaller units provide flow rates of 7, 15 or 20 liters per hour whilst the larger units deliver 30, 60, 90 or 120 liters per hour. Sophisticated microprocessor monitoring helps ensure optimum performance at all times – and you can rely on easy, cost-effective and convenient operation, with user-friendly controls, informative status displays, and simple maintenance routines.

User-friendly and informative monitoring

The PURELAB Prima range has been designed to give you full system control. All models continuously monitor and display water quality and operational parameters, with adjustable audio-visual alarms and consumable change reminders to ensure trouble-free operation. The comprehensive status displays allow you to check temperature-compensated conductivity, water temperature and production mode at a glance.

Additionally, PURELAB Prima 7/15/20 models feature a unique state-of-the-art GRID * control panel showing graphical illustrations of the operational mode, process flow path and reservoir water level, further simplifying the monitoring of information. They also incorporate an RS232 port so that you can make a permanent record of water quality and system parameters – essential for compliance with Good Laboratory Practice (GLP) guidelines.

Ease-of-use and low maintenance

Simple operation is a key element of the PURELAB Prima design. Each system features a large easy-to-use back-lit control panel with intuitive icons and a menu-driven system to guide you. Front-entry service doors enable you to quickly and easily replace consumables, whilst a simple sanitization regime helps maintain peak system performance. The PURELAB Prima utilizes an integral bacteriostatic pre-filter cartridge to remove chlorine and gross particulate contamination. No softener is required.

Tailored to your water supply

The PURELAB Prima product family can operate from a wide range of potable water pressures. For PURELAB Prima 7, 15 and 20 units, an optional integral boost pump can be specified where pressure is insufficient. PURELAB Prima 30, 60, 90 and 120 units have this boost pump built in as as a standard feature.

Technologically advanced design

Easy upgradeability

Flexibility is a key benefit of the PURELAB Prima range. A wide choice of flow rates is available to meet your current needs, with the potential to upgrade should you need higher volume to keep pace with future requirements.
