OB1 Microfluidic Droplet Pack
- Product SKU: LVF-PAK-DPL-SMALL
- Category: Elveflow, Microfluidic Pressure Controllers, Pressure Control, Pumps & Flow Controllers
Making droplets has never been easier with the Elveflow Microfluidic Droplet Pack! Based on the high-precision OB1 Mk3+ pressure controller, this bundle includes everything you need to generate monodisperse droplets out-of-the-box.
The Droplet Pack is completed by a user guide with detailed instructions to build your setup and generate droplets of the right size and frequency!
Available in two versions: Small (10-40 µm droplets) and Large (50-80 µm droplets).
Droplet generation made easy
The Elveflow Microfluidic Droplet Pack was designed to ease your daily lab work, by providing a complete and evolutive solution to generate droplets out-of-the-box!
- Unbox your Droplet Pack
- Install your system following the step-by-step User Guide
- Generate your droplets using detailed protocols and characterized microfluidic chips
Based on the high-precision OB1 Mk3+ pressure controller and MFS flow sensors, this pack comes with all the accessories you need to start generating reproducible and monodisperse (PDI <2%) water-in-oil droplets immediately.
Droplet Pack features
Two Droplet Pack versions are available, based on the droplet range:
- Small: for droplets between 10 and 40 µm
- Large: for droplets between 50 and 80 µm
Each pack contains the following:
- 1x OB1 Mk3+ flow controller with 2 channels (oil phase / water phase)
- 2x MFS flow sensors (for oil and water)
- 2x sets of flow resistors (for stable and accurate flow control)
- 2x ChipShop microfluidic droplet generators
- All necessary reservoirs and tubings
Created by a team of experts in droplet-microfluidics, the User Guide included in this pack details all the steps to build your setup and generate droplets of a defined size. Just follow the steps to generate droplets meeting your project's needs!
The Droplet Pack is evolutive: start with characterized microfluidic chips now, and use the same system with any other microfluidic chip.
Schematic of the Droplet Pack Large (for droplets of 50-80 µm). Only the flow restrictors and MFS change in the Small version, to get the best performances out of your microfluidic system.
