Embodiment Construction

[0048] figure 1 Different embodiments of sealing cones 101a - 101g are schematically shown.

[0049] Figure 2A A sealing cone 201 is shown schematically, comprising a predetermined breaking point 202 and a pin 203 .

[0050] Figure 2B A microfluidic system 205 with a sealing membrane 206 and channels 207 is schematically shown in addition to a sealing cone 201 comprising a predetermined breaking point 202 and a pin 203 . The sealing cone 201 is already arranged on the microfluidic system 205 . It is shown here how, when a force—outlined by arrow 204—is applied to sealing cone 201 , the predetermined breaking point 202 is pressed in by the pin 203 striking against the membrane 206 , so that via the The sealing cone is connected to the channel 207 of the microfluidic system 205 .

[0051] Figure 3AA device 300 for storing liquids for a microfluidic system 303 is schematically shown, which has a cavity 302 filled with a liquid, here configured as a channel, and a sealing...

Abstract

The present invention relates to an apparatus for hermetically sealed storage of liquids for a microfluidic system, which has at least one cavity and at least one sealing cone through which a connection to the microfluidic system can be established and which closes the cavity. The present invention also relates to the use of such an apparatus.

Description

Background technique [0001] In a microfluidic system such as a lab-on-a-chip (LOC) system, it is necessary to deliver biochemical reagents and samples onto or into a chip. In contrast to simple lateral-flow test strips for detection methods such as immunology, for molecular diagnostic tests multiple reagents are often required in chip systems. Easy-to-handle and user-friendly storage on a tablet in dry form, for example in freeze-dried form, is not always possible here. Another important difference between most molecular diagnostic tests and lateral-flow-test strips is that it is often necessary to use large amounts of analyte solution or wash solution, which due to its large up to The volume of several milliliters is difficult to integrate on the chip. [0002] To meet these requirements, for example, a storage container external to the chip with an external injection pump and a connection to the chip is used. Alternatively, the reagents are manually added to the storage c...
