Whether you are working on microfluidics, drug infusions, or complex chemical dosing, this programmable pump delivers high-accuracy infusion and withdrawal modes. It allows labs to automate multi-channel fluid dispensing, eliminating manual errors, saving time, and ensuring perfectly reproducible flow rates across all your research applications. Condition: Used, in very good cosmetic condition. We have power-tested the main controller, and it boots up smoothly with zero initialization errors. Please note that we were unable to perform further operational testing because we do not have the specific communication cable that connects the R70-2023 syringe holder to the main pump unit. It is being sold exactly as pictured.
