M-SWITCH™

barre verte

The M-SWITCHTM is a rotary valve with 11 ports.
One may select one of up to 10 solutions to be
delivered to a microfluidic device, or input one
fluid and direct it to up to 10 different locations.
When used with the Fluigent Automation Tool
software (MAT), the switch position and timing
may be programmed and automated as well as
other flow parameters. The M-SWITCHTM has a
very low dead volume and has a rapid switch
time of a few milliseconds.

Benefits

Compact device

 

Standard connections

 

Automation capabilities

 

Low internal volume

 

Applications

Sample generation and collection

In this application example, different concentrations of the molecule
of interest are injected into the chip generating water in oil droplets
containing various concentrations. The droplets are then sorted at the
outlet of the chip using the M-SWITCHTM regarding their concentrations.
Each step can be automated either by using Microfluidic Automation
Tool (MAT) or partially with live control and monitoring using ESSTM
Control dedicated software.

Sequential injections

In this application example, up to 10 liquids (4 on the schematic) are
selected sequentially to be delivered to the chip by the M-SWITCHTM.
The samples at the outlet of the chip may also be sorted by using a
2-SWITCHTM either into a collection tube or to waste. Each step can
be automated either by using Microfluidic Automation Tool (MAT) or
partially with live control and monitoring using ESSTM Control dedicated
software.
