Confluent™ PDP (Precision Dispense Pumps)
Manufactured by our Sapphire Engineering Division, these Precision Dispense Pumps offer a longer life and improved performance at a greatly reduced cost of ownership over competing products. While accurately dispensing volumes from less than 1µL up to 5mL, our pumps boast a guaranteed life of 5 million cycles (for a typical diagnostics application). Available in a variety of sizes and materials, all pumps can be customized to meet OEM customers’ specific needs.
