Devices for performing colorimetric assay with plucked human hair

摘要

Apparatuses are disclosed for performing calorimetric assays with plucked human hair using a device adapted for that purpose. This device may include a transparent reaction vessel connected via a capillary tube to a burst pack, and connected via another capillary tube to a funnel, into which a plucked human hair may be placed.

主权项

1. A device for performing a colorimetric assay comprising:
an encasement; a cavity within the encasement comprising a burst pack comprising a first reagent, the burst pack situated such that it may be burst by pressure from one or more human fingers, wherein the first reagent reacts with the follicle of a human hair to produce a change in a measurable optical property of the reagent; a transparent reaction vessel within the encasement comprising a reaction chamber; a first capillary tube opening on one end to the reaction chamber, and opening on another end to a funnel, said funnel opening to the atmosphere external to the reaction vessel; and a second capillary tube providing a fluid connection between the cavity and the reaction chamber.
