Varian PrepStar SD-2 Solvent Delivery Module

The Varian PrepStar SD-2  Solvent Delivery Module is designed and engineered for the purification needs of organic/medicinal chemists, process development engineers and small scale production operators. The PrepStar SD-2 is designed for higher flow rates at higher pressure solvent delivery, for maximum throughput. The PrepStar SD-2 Solvent Delivery Module is the most compact preparative HPLC modular design in its performance class, with both low and high pressure gradient options offering maximum scale-up flexibility and economy. Characterized by high flow consistency, reliability and low pulsation, the PrepStar SD-2 pump is an outstanding performer.

• Broad range of applications – purify small organic molecules up to larger proteins by using optional inert “Bio” flow paths 
• Maximize versatility – manual, automatic, isocratic, gradient, low and high pressure operation with the three different flow rates means you are never far from a solution
• Reduce capital investment – low pressure gradient systems need only one PrepStar SD-2, offering the most cost-effective scale-up format – 200 mL and 800 mL versions only
• Reduce operating costs – maximize sample recovery with the “unique” recycle option and reduce processing time
• High throughput chromatography – using larger particle media along with column overload strategies, this bench top pump / system offers the most economical solution to your small scale production needs
