APPARATUS FOR TAKING AN ACCURATE PHOTOMETRIC MEASUREMENT OF A LIQUID

摘要

An apparatus for taking an accurate photometric measurement of a liquid by way of forming a specimen volume of a controlled optical path length for use with photometric measurement equipment is disclosed herein. In some embodiments, the apparatus comprises a transparent body configured for displacing a volume of a fluid and at least one support element wherein the support element is configured to maintain the transparent body at a location such that specimen fluid may enter a void volume to form a specimen volume of a controlled optical path length. In some embodiments, the apparatus comprises a plurality of transparent bodies interconnected by a web such that the transparent bodies are maintained at a spacing arrangement which allows for them to be inserted into the wells of a microplate in order to create a plurality of specimen volumes of a controlled optical path length.

主权项

1. An apparatus for taking accurate photometric measurements of fluids, comprising:
a transparent body having a top end and a bottom end, wherein
the top end comprises a top surface, andthe bottom end comprises a bottom surface; at least one side wall; at least one support element; and a void volume lying between the bottom surface of the transparent body and at least one outermost part of the at least one support element; wherein
the transparent body is configured for displacing a volume of a fluid, andthe at least one support element is configured to maintain the bottom surface of the transparent body at a predetermined distance from a surface upon which the at least one support element may rest such that a volume of fluid may enter the void volume to form a specimen volume of a controlled optical path length.
