Product Overview

HM-QT8 is a handheld fluorometer for fluorescence-based nucleic acid and protein concentration measurement. It supports eight samples with single-color optics and a 5-inch touchscreen. Sample input is 1–20 μL, used with the appropriate fluorescence assay reagents. Use it to assess nucleic acid input for sequencing library preparation and concentration checks in PCR research workflows.

Key Features

Fluorescence-based quantification with high-efficiency LED excitation and a SiPMT detector.
Micro-volume sample input of 1–20 μL.
Five-decade dynamic range and two-point calibration.
Open reagent platform compatible with suitable Qubit® series quantification kits.
Integrated 5-inch touchscreen for selecting assays and reviewing results.

Applications

Use fluorescence assays to quantify sample input during NGS library preparation, check DNA concentration before PCR research, and assess low-concentration nucleic acids or proteins after extraction. The integrated touchscreen supports routine bench and portable laboratory workflows. Assay selection must match the optical configuration and reagent kit; microRNA and general RNA assay coverage differ by model.
