Waters 600 HPLC Pump
Waters 600 Solvent Delivery Pump
The Waters 600 is considered one of the most popular HPLC pumps ever produced. It was in production for about 25 years and received several upgrades over that time. The Waters 600 multisolvent delivery system was recently discontinued but there are many replacement parts and systems available on the market today.
Until now, the design of low-pressure gradient systems was based on tradeoffs. To maintain the simplicity of a true single pump configuration, instrument manufacturers accepted inferior performance - blending accuracy and precision would vary with changes in system backpressure and flow rate. To compensate, some manufacturers relied on additional mechanical complexity, but the extra pumps and plumbing began to obscure the original benefits of the low-pressure concept - reliability, convenience, and cost.
