Distributed & Imported by QEMIX
QEMIX is proud to be the Authorized Distributor of DUKSAN Pure Chemicals in Vietnam, importing directly from Korea and developing the DUKSAN chemical range for laboratories, testing centres, pharmaceutical, food and environmental facilities and research institutes across Vietnam.
Authorized-distributor status is more than a line on a website. It determines where the goods come from, whether the quality documents match the lot you receive, and who is accountable when a technical question arises. This article sets out exactly what that status means for your laboratory.
What is different about buying DUKSAN through an authorized distributor?
The six points below directly affect your analytical results and your audit records.
Supplied directly by DUKSAN
Goods travel straight from the DUKSAN plant in Korea to the QEMIX warehouse, with no uncontrolled intermediaries. This removes the risk of aged stock, repackaged goods or product with an unknown import route.
Traceable to the import shipment
Every bottle can be traced to its lot number, production date, expiry date and the shipment it arrived on — a requirement for ISO/IEC 17025 assessments and for investigating an out-of-trend result.
Genuine, lot-specific COA and SDS
The COA is issued by DUKSAN for the exact lot you receive — not a “representative” COA from another lot. The SDS is the latest GHS version, with support for chemical declaration files where required.
Stock held in Vietnam
Frequently used items are kept in local stock by QEMIX, cutting lead times from weeks to days. Your laboratory does not have to stop a test because a solvent has run out.
Help choosing the right grade
QEMIX advises on the purity grade for your test, compares the parameters in DUKSAN’s Specification and warns you when a cheaper grade would compromise your results.
Factory orders on request
Items not held in stock can still be ordered, including large pack sizes and specialised products. QEMIX works directly with DUKSAN to confirm availability and production time.
Authorized supply versus grey-market supply
The difference is not the list price — it is what you have to prove when someone asks.
| Criterion | Through the Authorized Distributor (QEMIX) | Unauthorised source |
|---|---|---|
| Import route | Imported directly from DUKSAN, Korea | Unknown; possibly several layers of intermediaries |
| COA | Matches the lot number on the packaging; issued by the manufacturer | Often a COA from another lot, or a photocopy |
| Lot traceability | Traceable to the shipment and production date | Difficult or impossible |
| Shelf life | Controlled through stock rotation | Risk of receiving short-dated goods |
| Technical support | Named contact, documented responses | Usually ends at the point of sale |
| During audits | Complete supplier file, provable origin | Prone to non-conformities |
For laboratories operating under ISO/IEC 17025, GMP or ISO 15189, the origin of chemicals is part of the quality record — not just a purchasing matter.

Understand the grade before you order
Choosing the wrong purity grade of the same chemical is the most common cause of baseline noise, bias and repeated sample runs.
Analytical grade with tightly controlled assay and impurity limits. For quantitative analysis, titration, QC testing and research.
DUKSAN’s general-purpose grade (note: “EP” here means Extra Pure, not European Pharmacopoeia). For preparing solutions, rinsing, sample work-up and steps that do not determine the accuracy of the result.
Adequate purity at lower cost. For non-quantitative work that does not require instrumental-analysis standards.
Six solvent grades — LC-MS, Ultimate, Pesticide, HPLC, DNA Biosynthesis, Ultra Dry — controlling UV absorbance, evaporation residue, MS background or water content depending on the grade. For chromatography, residue analysis and synthesis.
Some items are additionally certified to ACS or pharmacopoeial monographs (for example Chloroform GR/AR/ACS; Methylene Chloride GR/Ph Eur/BP/NF). Use these when your method explicitly cites that standard.
If your method cites a pharmacopoeia or a specific standard, send the test name to QEMIX. We compare the parameters in DUKSAN’s Specification and confirm the appropriate grade before you place the order.
