Quartz Cuvettes and Flow Cells Supplier & Factory for the Milan Market

Optical glass such as N-BK7 or standard borosilicate exhibits strong optical absorption cutoffs starting around 320–340 nm, rendering it useless for UV range measurements. Synthetic quartz (JGS1) maintains high transmittance (>80% without anti-reflection coatings) from 190 nm through the visible and near-infrared spectrum to 2500 nm, making it essential for DNA/RNA quantitation (260/280 nm) and aromatic compound analysis.

We employ direct thermal optical contact bonding (molecular fusion). The glass surfaces are polished to λ/10 flatness and brought into intimate molecular contact before undergoing high-temperature diffusion annealing. No epoxy resin, glues, or low-melting frits are used, meaning the cell handles corrosive solvents, chlorobenzenes, and extreme pH cleaning cycles without leakage or joint degradation.

Yes. We routinely fabricate micro-apertures (from 10 µL down to sub-microliter volumes) for flow cytometry, laser Doppler velocimetry, and HPLC detectors. We provide complete integration including CNC-machined PEEK or 316L stainless-steel external retaining jackets with standard 1/4-28, UNF, or ferrule plumbing interfaces.

Standard analytical cells feature a 10 mm path length with a mechanical tolerance of ±0.01 mm. For critical reference spectrophotometry, our matched pairs or sets are calibrated to within ±0.005 mm path length tolerance and transmission-matched to within 0.1% across the 200–800 nm spectrum.

All components are cleanroom-washed, vacuum-sealed in anti-static lint-free polymer packages, and surrounded by high-density multi-layer EPE foam suspension boxes. Export deliveries to Malpensa (MXP) or direct to client facilities in Milan/Monza arrive via DHL Express/FedEx priority with full tracking and export insurance.
