The Elga Labwater Purelab Classic Uv/uf CLXXUVFM2 is a sophisticated water purification system designed to produce exceptionally pure water. Its core function is to deliver Type I water, which is the highest grade of laboratory water, essential for the most demanding applications. This grade signifies water with minimal dissolved ions, organic compounds, and pyrogens.
Key specifications include a Dispense Rate and Make Up Flow Rate of up to 2.0 LPM. This flow rate is practical for filling various lab containers efficiently, from small vials to larger flasks. The system integrates both UV (Ultraviolet) sterilization and UF (Ultrafiltration), which are critical for removing endotoxins and nucleases that standard deionization might miss. The Catalog number is 89204-072, and its Supplier No. is CLXXUVFM2. The unit itself falls under the Type: INST/EQUIP 1500+, indicating its classification as an institutional/equipment model capable of higher throughput.
These specifications translate directly into practical benefits for the end-user. The Type I water quality ensures that experiments are not compromised by contaminants, leading to more accurate and reproducible results. The 2.0 LPM dispense rate means less waiting time between preparing samples or refilling reagents, significantly boosting lab productivity. The inclusion of UV and UF stages is particularly important for biological and molecular biology applications where trace contaminants like endotoxins can ruin experiments; this integrated approach simplifies the purification process and enhances safety.
Performance & Functionality
The primary job of the Elga Labwater Purelab Classic Uv/uf CLXXUVFM2 is to produce and dispense ultra-pure water, and it excels at this task.
