Elga 's PURELAB Ultra water purification unit , model Ultra Sc Mk2 , is a high-performance, used system designed to provide ultrapure water with extremely low levels of impurities. Ideal for laboratories, medical applications, and industrial sectors, the PURELAB Ultra is a versatile and compact solution, capable of adapting to various configurations. Being a used unit from 2007, it offers excellent savings while maintaining high quality standards.

Appearance and Visual Characteristics

This unit is in good aesthetic condition, with a compact and functional design that allows for easy placement on a countertop, under the counter, or on a wall. Thanks to its compact dimensions of 155x95x105 mm , the PURELAB Ultra Sc Mk2 can be installed in limited spaces without sacrificing water treatment quality. It features a robust external frame that protects the internal components, making it suitable for even intensive work environments.

Visually, the unit is well-structured, with a professional finish that reflects the quality of the Elga . The controls and display are easily accessible and legible, allowing operators to monitor and adjust parameters easily.

Components and Structure

The PURELAB Ultra Sc Mk2 features an advanced filtration system, including reverse osmosis membranes and deionization resins, essential for producing ultrapure water. The system requires a 100-240V 50 /60Hz , making it compatible with standard international power grids. The unit is designed to be fed with pre-treated water, typically from a reverse osmosis system, ensuring a multi-stage purification process to remove contaminants and impurities.

Operation and Use

The PURELAB Ultra is easy to use and integrates seamlessly into any laboratory. The system operates by feeding from a reverse osmosis system or a local pretreatment system, such as the PURELAB Prima , another Elga . Water is purified through the membrane and resin system, with the option of storing it in a docking vessel or suitable tank to ensure a continuous supply of ultrapure water.

The system can be used in point-of-use mode, connected directly to a ring supply network to draw water without the need for additional equipment. This feature makes it particularly useful in industrial, chemical, and pharmaceutical environments, where process continuity is essential.

Optimal Usage Parameters and Formulas

To ensure maximum performance, it is essential to monitor several key parameters. The incoming water must have a low conductivity, typically achieved through a reverse osmosis system. The final purity level is determined by the specific resistance of the outgoing water, which can be measured with a resistance meter. The formula for calculating purity is:

$$\text{Resistance (MΩ/cm)}$$

The higher the resistance value, the purer the water. For ultrapure water, the resistance must be greater than 18.2 MΩ/cm .

Maintenance and Safety

Proper maintenance is essential to ensure the long life and efficiency of your PURELAB Ultra . The system requires periodic replacement of the filter cartridges and reverse osmosis membranes, operations that can be easily performed by qualified personnel. It is also important to perform regular checks of the operating parameters via the control panel to prevent performance drops.

CE safety regulations . If not, it will be necessary to adapt the unit to current regulations by installing updated safety devices, such as circuit breakers and overload protection systems.

Sectors of Use

The PURELAB Ultra Sc Mk2 is used in a wide range of industries, including:

• Pharmaceutical : for the production of highly pure water for drug synthesis and manufacturing processes.
• Chemical : For use in chemical analysis laboratories, where contaminant-free water is required to ensure accurate results.
• Cosmetic : for the formulation of products that require ultrapure water to avoid unwanted reactions.
• Food : in production processes where high-purity water is essential to ensure the safety and quality of the final product.
• Dietetics and medical devices : in environments where water purity is essential to prevent contamination.

Advantages of Buying Used

Buying a used PURELAB Ultra Sc Mk2 can be a great deal, especially for those looking for quality at a reasonable price. The cost savings compared to a new unit are obvious, but the advantages don't stop there. Being a used and tested unit, it has already proven its reliability over time. Furthermore, thanks to the robustness of its components and proper maintenance, used brands like Elga still guarantee high-level performance.

Conclusion

The Elga PURELAB Ultra water purification unit, model Ultra Sc Mk2, is an excellent solution for those seeking an ultrapure water purification system for laboratories and industrial applications. Its compact size, versatility, and brand reliability make it a sound investment. Even as a used unit, it offers high performance, meeting the purity standards required by critical industries such as pharmaceuticals and chemicals.
