Hamilton™ Constant Rate-700 HPLC Syringes & Replacement Parts

Syringes are designed to delive reasy, reproducible injection of liquid samples into an injector on HPLC instrumentation. The CR-700 standardizes three major variables: sample volume, rate of injection, and depth of needle penetration. Even when operated by different technicians, the CR-700 provides reproducibility of +1% of the total syringe volume in routine procedures.
