Custom OEM Quartz Laboratory Cuvette Manufacturers & Supplier in Daegu

JGS1 is a high-purity synthetic fused silica synthesized from silicon tetrachloride vapor oxidation. It features virtually zero metallic impurities and exceptional deep-ultraviolet transmission extending from 185 nm to 2500 nm, rendering it the standard choice for DNA/RNA characterization at 260 nm, protein analysis at 280 nm, and UV-excited fluorometry.

JGS2 is fused from natural high-purity quartz crystal sand. It provides outstanding optical performance across the 220 nm to 2500 nm spectrum, ideal for standard industrial UV-Vis quality testing in water treatment and chemical manufacturing.

JGS3 is an electrically fused quartz engineered for infrared applications with minimal hydroxyl content ([OH⁻] < 5 ppm). It transmits efficiently from 260 nm up to 3500 nm, suppressing the strong water absorption dip around 2730 nm for pristine near-infrared (NIR) research.

Our standard laboratory cuvettes (e.g., standard 10 mm pathlength cells) are maintained within an ultra-strict tolerance of ±0.005 mm, with custom scientific cells achievable down to ±0.002 mm upon request. We employ double-beam laser optical interferometers and calibrated gauge blocks traceable to international metrology standards.

Every production batch destined for South Korean analytical institutions is supplied with an individual or batch Optical Inspection Certificate confirming pathlength, window parallelism (≤15 arcseconds), and baseline spectrophotometric transmission curves.

Yes. OEM and ODM bespoke fabrications represent over 60% of our production volume. We accept engineering files in PDF, DWG, DXF, and 3D STEP formats. We routinely fabricate microfluidic flow cells, demountable cells, jacketed temperature-controlled quartz cuvettes, black-masked microcuvettes, and specialized multi-pathlength cells.

Our optical engineering desk reviews drawings and replies with comprehensive DFM (Design for Manufacturability) feedback within ≤5 hours.

For standard stocked catalog items, dispatch occurs within 24–48 hours. Custom OEM prototypes typically require 7 to 10 business days for laser cutting, precision polishing, diffusion fire-welding, and optical verification. Production batches of 100–1000 pieces are typically completed within 14–20 business days.

Shipments to Daegu are routed via express air carriers (DHL, FedEx, UPS) directly to Daegu International Airport (TAE) or through Incheon (ICN) with dedicated domestic bonded ground transit, arriving at your laboratory bench within 2 to 4 business days post-dispatch.

We recognize the fragile nature of optical components. Each cuvette is first ultracleaned and secured inside an individual antistatic dust-free acrylic case with lint-free optical lens wrapping. These cases are embedded within high-density, shock-absorbing EVA foam blocks contoured precisely to the container profile.

The foam inserts are packed inside corrugated export shipping boxes and enclosed within exterior reinforced wooden crates with internal shock-indicator labels, guaranteeing zero physical impact damage during overseas air transit.

Because our quartz cuvettes are completely fire-fused without adhesives, they safely withstand aggressive solvent cleaning that would destroy ordinary glued cuvettes. For organic residues, soak in spectrophotometric-grade ethanol, acetone, or a 1:1 mixture of methanol and concentrated hydrochloric acid.

For stubborn biological protein residues, a short treatment with 3M nitric acid or warm dilute piranha solution is completely safe for our molecularly fused quartz. Note: Never use hydrofluoric acid (HF) or strong hot alkaline solutions (>pH 11.5) as they will chemically etch polished fused silica surfaces.
