UV-clear microplates for DNA purity checking

publication date: Feb 5, 2024
author/source: Azenta Life Sciences


Ultra Optically Clear assay plates from Azenta Life Sciences provide high optical transmission in the UV waveband, making them ideal for labs tasked with DNA purity measurements performed at 260 / 280nm. The high UV waveband transmission of these plates is derived from an ultra-clear cyclic olefin copolymer (COC) base, which gives superior results by delivering very low background absorbance and low autofluorescence.

Using a proprietary laser welding technique to attach a thin 70um COC base to an opaque frame, the incredible optical clarity of these plates combined with their low background noise delivers superior transmission of signals at low UV wavelengths compared to standard optically clear bases made from glass or polystyrene. The unmatched optical performance provided by Azenta Ultra Optically Clear assay plates allows you to undertake DNA purity measurements in the plate well, without removing any sample, thus reducing sample loss, and improving throughput in automated workflows.

Manufactured from COC, Azenta Ultra Optically Clear assay plates are not only more robust than quartz-based assay plates, but also offer excellent chemical resistance to a wide range of solvents including DMSO, ketones and alcohols which are known to degrade standard polystyrene plates.

To safeguard their optical surface from scratches and ensure consistently crystal-clear results, each plate comes with a protective film. Additionally, these assay plates are guaranteed to be free from DNase, RNase, and human genomic DNA.

Each Ultra Optically Clear assay plate features an alphanumeric grid enabling easy well and sample identification. If required these plates can be supplied with a low-profile lid to help preserve sample integrity or barcoded to help streamline automation.
