TWO VERSIONS FOR “SMALL” OR “LARGE” DROPLETS

Our two versions only differ by the flow rate range of the oil phase.

The SMALL version includes a MFS-D-3 allowing perfect feedback loop control of the flow rate to generate droplets ranging from 10 to 40 µm diameter.
The LARGE version includes a MFS-D-2 allowing perfect feedback loop control of the flow rate to generate droplets ranging from 50 to 80 µm diameter.

Important note: our products are all intercompatible and you may acquire additional flow rate sensors or add extra products for specific applications. You will still benefit from the centralised ESI software control.

More details about the droplet pack

A well-chosen microfluidic chip

The microfluidic chip is where the two immiscible phases (water and oil here) are precisely injected and mixed to generate monodisperse droplets (CV < 3%). The two microfluidic chips are made of Topas. Topas is a cyclic olefin copolymer (COC) resin which is a chemical relative of polyethylene and other polyolefin plastics.

A reservoir holder with 2 push-in connectors

Are you working with small samples or are you looking into manufacturing 100x mLs of emulsion? Elveflow offers a comprehensive range of reservoirs compatible with our OB1 Flow Controller, from 1.5 mL Eppendorf tubes to 100mL bottles.

Enhanced flow resistor systems

Flow resistors consist in the assembly of PEEK capillaries with small internal diameters. Those resistors are used to increase the resistivity of the microfluidic system to improve the stability and control of the flow rate in the system.
