Benefit from the highest standards of microfluidic instruments

Microfluidics brings reproducibility and control over droplet size that are not achievable with any other technique.

Moreover, it is an ideal technique to handle ultra small volumes and control droplet generation precisely. It give you flexibility to easily generate identical droplets with the same content or to create individual droplets with unique payloads.

This Droplet Generation Pack includes our OB1 flow controller best-seller.

Thanks to the performance of this instrument, you will be able to generate:

  • Droplets ranging from 10 to 80µm diameter (and more using alternative microchips)
  • Highly monodisperse droplets (CV<3%)

Overview of the droplet pack setup

We can provide you with two Droplet Pack versions : the small version, to generate smaller droplets ranging from 10 to 40µm and the large version, for droplets ranging from 50 to 80µm diameter. Each Pack is composed of:

  • One OB1 flow controller with 2 control channels (one for each phase)
  • Two flow rate sensors (one for each channel)
  • Two fluidic resistances (for stable and accurate flow control)
  • Two Microchips from ChipShop, a leading microfluidic chip manufacturer.
  • All necessary reservoirs and tubings.

Droplet Generation Pack User Guide

  • All necessary accessories: tubing, connectors, filters, etc…
  • 1 x 10 mL vial of droplet oil (HFE-7500)
  • Control and automation software (Elveflow Smart Interface)
  • 1 x User Guide which includes:
    • Detailed contents list
    • Step-by-step installation guide
    • Detailed protocol to generate droplets with the Pack
    • Screenshots and pictures to get familiar with our equipment.

Two versions available depending on the desired 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.

Chip included in the droplet pack

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 resistances are used to increase the resistivity of the microfluidic system to improve the stability and control of the flow rate in the system.
