We disclose a device and method for collecting a urine sample as a user urinates into a toilet. The device further conducts analytical measurements which may include spectral, colorimetric, and chemical assays. The user need only urinate normally into the toilet. A urine collection trap, which includes a vertical slit, may capture a urine sample which has a volume in the microliter range. Pumps may divert the urine from the vertical slit into a conduit that is connected to spectral analysis devices and other devices for analyzing the urine sample. The disclosed device is both convenient and prevents unsanitary urine spills.

To provide an inspection system capable of performing a target biological reaction under temperature conditions suitable for the reaction even with reciprocal liquid feeding. An inspection system including at least: a sensor chip with a flow path having a reaction site for performing biological reactions; a liquid feeder that causes reaction liquid to flow into and out of the flow path; and a first temperature adjuster that adjusts temperature of reaction liquid flowed in the flow path, where the system performs reciprocal liquid feeding by the liquid feeder where some of the reaction liquid flowed in the flow path is caused to flow out of the flow path and to flow in again. The inspection system includes a second temperature adjuster that, during reciprocal liquid feeding, adjusts temperature of the reaction liquid flowed outside the flow path through temperature adjustment of a liquid holding section of the liquid feeder.
