In wet-process chemistry, the package is part of the process. A drum that sheds particles or leaches metals doesn't just miss a spec — it contaminates baths, threatens yield, and puts a qualified supply line at risk. COEXCELL's ultra-pure tri-layer models are engineered, tested, and documented against exactly that risk.
The drum must not become a contamination source between fill and dispense — at the wall, at the closure, or in handling.
HowTri-layer coextrusion isolates colorants and UV stabilizers in the exterior structure; drums are finished in a Class 1000 clean-room environment by gowned technicians and automated equipment.
Product-contact surfaces must hold metal extractables to the level your chemistry qualifies against.
HowThe chemical only touches a virgin ultra-clean HDPE inner liner, available in three high-purity resin grades matched to your specification.
Cleanliness has to be measured and documented — not asserted — before the drum reaches your fill line.
HowCleanliness is verified in our in-house Class 100 liquid particle-count laboratory testing, with results documented per configuration.
A representative sample of the electronic wet chemicals packaged in COEXCELL ultra-pure drums today. Compatibility and configuration are confirmed per chemistry with our technical sales team.
All three share tri-layer construction, the virgin inner liner, Class 100 LPC verification, and a unique traceability label per drum. Choose on packing group, extractables target, and pressure.

Semiconductor qualification runs on evidence. These are the controls behind every ultra-pure drum we ship — each one producing paperwork, not adjectives.
Cleanliness verified in our in-house liquid particle-count laboratory testing.
Post-forming finishing performed in a clean-room environment with recorded air-quality readings.
Drum body weight confirms material content; gauge measurement confirms wall thickness and layer distribution.
IC, K55UP, and C55UP drums each carry a unique traceability identification label.
Certification documents, technical data sheets, and test summaries are available per configuration.
See the full quality processShare as much or as little as your disclosure rules allow — qualification runs on requirements: the specification you qualify against, the packing group, and the service conditions.
The packing group, the purity specification you qualify against, and performance needs such as pressure or specific gravity.
Our team matches those requirements to a model, resin grade, and closure or dip-tube configuration — with its exact UN/DOT marking.
Certification documents, technical data sheets, and test summaries are provided per configuration, so your qualification paperwork has evidence to cite.
Certifications are stated per model and configuration and are never generalized. An approval for one configuration is not extended to another — the same discipline your auditors apply.
Answers to the questions we hear most before a first quote. If yours isn’t here, the form is the fastest route to a specific answer.
Representative examples include CMP slurries, HF, HNO₃, HCl, HClO₄, IPA, NMP, NH₄OH, TMAH, and EBR solvents. Compatibility and the right model, resin grade, and closure configuration are confirmed per chemistry with our technical sales team.
Three tri-layer ultra-pure models: the IC55UP workhorse with a 300 kPa option, the K55UP for operations targeting the lowest metal extractables, and the two-piece C55UP for Packing Group I chemistries requiring an X-rated marking. All are 55-gallon drums with virgin ultra-clean inner liners, verified in Class 100 liquid particle-count laboratory.
Tri-layer coextrusion isolates colorants and UV stabilizers in the exterior structure, so the chemical only contacts a virgin ultra-clean HDPE inner liner. Inner-layer resins for the IC and K55UP product lines are available in three high-purity grades, allowing the drum to be matched to your extractables specification.
A 300 kPa version of the IC55UP, embossed 1H1/Y1.9/300, is available for higher-pressure service, supporting global transport. For Packing Group I chemistries, the C55UP carries the X-rated UN marking that PG I service requires. Confirm the right configuration for your material with our technical sales team — selecting the correct package for a given chemistry remains the filler's responsibility.
No. Many semiconductor customers can't disclose process chemistry, and our quoting is built around requirements instead: the packing group, the purity specification you qualify against, and performance needs such as pressure or specific gravity. From those, we recommend a model and configuration with the certification documents to support qualification.
