LDA-02 Independent Dual Channel Syringe Pump
The LDA-02 Dual Rate Syringe Pump brings together two fully independent execution units in one compact system, featuring an integrated dual-pump design with an intelligent control hub. What once required two separate devices can now be accomplished with a single machine—capable of independent, synchronized, or programmed operation. This not only eliminates redundant procurement costs but also delivers a significant boost in experimental efficiency.
From high-precision biopharmaceutical research to complex microfluidic workflows, the LDA-02 provides seamless and efficient solutions, streamlining processes and making your experiments smarter and more productive.
