Abstract
A microfluidic chips (1), microfluidic fluid reservoirs (2), microfluidic kits (1,2) comprising a microfluidic chip (1) and a microfluidic fluid reservoir (2), and to methods of operating such microfluidic kits (1,2). According to the invention, at least either the microfluidic chip (1) or the microfluidic fluid reservoir (2) includes a distensible diaphragm (4) or a distensible wall region, respectively, which is distensible into the fluid reservoir (2), with volume displacement taking place, in order to move a fluid (8) out of the fluid reservoir (2) through the fluid channel inlet (6) into a fluid channel (7) of the microfluidic chip (1).
Claims20
A microfluidic chip, comprising:
- a recess for receiving a fluid reservoir,
- a distensible diaphragm adjoining the recess,
- an actuator, and
- a fluid channel inlet adjoining the recess,
- wherein the distensible diaphragm is distensible into the recess by the actuator with volume displacement taking place.
A microfluidic chip comprising:
- a recess for receiving a fluid reservoir having a rigid wall region, a distensible wall region and an openable wall region,
- an actuator adjoining the recess, and
- a fluid channel inlet adjoining the recess,
- wherein the distensible wall region of a fluid reservoir disposed in the recess is distensible into the fluid reservoir by the actuator with volume displacement taking place.
