Mass Spectrometry & Spectroscopy 15 Solve bioassay challenges: Fluorescence-free,


UV-transparent, solvent-resistant quartz plates Researchers measuring protein at 280 nm or nucleic acids at 260 nm face persistent problems: the microplates themselves interfere with readings. Below 320 nm, plastic and plastic-bonded plates absorb signifi cantly whilst generating background fl uorescence, creating noise that compromises sensitivity – particularly frustrating with low-concentration samples.


Starna Scientifi c’s monolithic quartz 96-well plates address these limitations through full synthetic quartz construction. Heat-fused without adhesives, these single-piece plates deliver complete UV- Vis transmission from 180 nm where plastic alternatives simply cannot perform.


But optical performance is only part of the story. Quartz withstands aggressive solvents, DMSO, DMF, strong acids, that would dissolve or deform plastic plates. It also survives repeated autoclaving at 121°C without warping or leaching contaminants, supporting indefi nite reuse and sustainable laboratory practices.


Manufactured under ISO 9001 quality management, each plate delivers consistent performance over years of use. Standard specifi cations include 300 µL well capacity and 2 mm fl at base geometry, ensuring compatibility with conventional plate readers. The fl uorescence-free, single- piece construction eliminates contamination risks whilst enabling sensitive assays where signal- to-noise ratio is paramount.


For demanding research in biopharmaceutical development, clinical diagnostics, and academic laboratories, these capabilities prove essential when measuring low-concentration samples with maximum sensitivity and reproducibility.
