OLIS FMX-2 Fast Mixer

This integrated mixing and data acquisition system is perfect for teaching and research laboratories that have a need for faster mixing than manual pipette injection, but cannot justify the need or cost for a “stopped-flow.”

The Olis FMX-2 features a flow cell compartment that fits the HP 8452 diode array system. The FMX-2 is pneumatically driven and fired manually, so that the accessory can be used with spectrometers with or without Olis data acquisition software.

A rotating stop turret supports multiple repeat shots with user-adjusted volume. Three reagent syringes are used: two drive syringes are mounted vertically and a third syringe is attached to a T-mixer. This design allows one to wash the flow cell using the third syringe or load a third solution as a baseline while keeping the reagents preloaded in the drive syringes.
