保护芯片实验室设备的功能
微流控芯片实验室系统,简称 LOC,可在最小的空间内实现大量的过程。 芯片实验室分析紧凑型芯片上的液体,用于生物、化学或物理过程的过程分析。
芯片实验室使用毛细管力来传输几皮升或微升的流体。
使用 TopMap 轮廓仪等基于显微镜的专用表面计量,允许您检查微流体 芯片实验 通道的尺寸公差,以高精度评估芯片实验室通道深度或宽度,确定体积或测量整个芯片的平面度。
如果芯片实验室的平行度、台阶高度或平面度不在非常严格的公差范围内,并且不符合规范,这将影响芯片实验室分析的性能和可靠性。

Raimund Rother, process engineer at Hahn-Schickard:
Applying the sealing film to the cartridges is challenging: on the one hand, the demand of achieving a high seal strength without closing the fine channels of the cartridge during bonding. Secondly, production tolerances regarding the injection molding thicknesses cannot be eliminated completely, which has to be compensated when sealing. To adjust the sealing tool precisely, we measure the height levels of the cartridge using a scanning whitelight interferometer. This 3D measurement data then forms the basis for designing the sealing tool.
