Overview
This HTS category, 9027.20.50.30, specifically encompasses instruments designed for electrophoresis. Electrophoresis is a laboratory technique used to separate molecules, such as DNA, RNA, or proteins, based on their size and electrical charge. Instruments in this classification facilitate this separation process, typically involving the application of an electric field across a medium containing the sample.
Within the broader group of chromatographs and electrophoresis instruments, this code distinguishes itself from its siblings by its exclusive focus on electrophoresis. While categories like 9027.20.50.50 (Gas chromatographs) and 9027.20.50.60 (Liquid chromatographs) cover instruments for separation based on different physical principles (partitioning between phases), 9027.20.50.30 is dedicated to apparatus employing electrical forces for molecular separation. The remaining sibling category, 9027.20.50.80, covers any other electrophoresis instruments not otherwise specified.
As a leaf node, this classification does not have further subdivisions. Therefore, practical classification under 9027.20.50.30 relies on the fundamental function of the instrument: its ability to perform molecular separation through the application of an electric field. This includes various types of electrophoresis apparatus, such as gel electrophoresis systems, capillary electrophoresis systems, and associated power supplies and detection units, provided their primary purpose is electrophoresis.
