Type III hard-anodized aluminium body, interchangeable silicone inserts, silicone gasket and 304 stainless hardware. The slot openings were not guessed — we measured 878 containers across 7 endoscope brands before deciding how a case should be built.

A sterilization container is not a storage box — it is one link in cleaning, sterilization, storage and issue. If any link fails, the chain fails.
Removable inserts and radiused internal corners avoid protein and endotoxin traps; baskets run in ultrasonic on their own.
PPSU lets staff verify contents without opening; laser marking and five colour codes prevent mix-ups.
Perforated lid with filter ports supports steam penetration at 134°C; latches stay shut in transport.
Sealing relies on silicone compression rather than an interference fit, limiting recontamination.
Gaskets and inserts are separate part numbers — replace the part, not the case. Validation target: 200 cycles.
Container dimensions compiled item-by-item from official data of 7 brands
of samples fall in 246–290 mm width; the industry converges on a 35 mm band
Ø2 / 2.7 / 4 / 5 / 10 / 12.5 mm interchangeable inserts cover 90%+ of diameters
wash–134°C sterilize–dry validation target — a target, not a completed claim

You can read this straight out of OEM catalogues: KARL STORZ narrow endoscope containers keep a constant 152.4 mm (6″) width, and 4, 5 and 10 mm scopes share the same width and length — only working length changes the case. Large containers hold 279.4 mm (11″) with just three height steps.
Aluminium for weight, PPSU for transparency, silicone for sealing, stainless for strength — the combination pays off only when all four gates clear.
CTE of aluminium ≈ 23 and PPSU ≈ 50 (×10⁻⁶/°C). Sealing uses silicone compression (20–30%) instead of an interference fit, so elastic parts absorb the differential.
Identify the hardest-to-clean features first, then test protein residue, endotoxin and TOC. Nothing ships until all three pass.
Positive-pressure decay, vacuum bubble and helium methods combined — both as-new and after 200 cycles.
Wash → 134°C steam → dry is one cycle; after 200, appearance, dimensions, sealing and residue are re-tested into a shareable report.
| Part | Material | Key parameter | Control point |
|---|---|---|---|
| Body / lid | Aluminium 3003 / 6061 | Type III, film 25–50 μm | Film thickness and sealing (GB/T 8013), mark legibility |
| Transparent parts | PPSU | mould 130–160°C + annealing | Residual stress, crazing, clearance against aluminium |
| Gasket | Medical-grade silicone | compression 20–30% | Compression set after 200 cycles |
| Baskets / liners | 304 / 316L | wire and mesh per instrument | Ground welds, Ra, deburring |
| Fitting sizes | — | CpK ≥ 1.33 | Critical-size inspection, insert interchangeability |
Every claim on this site is registered with its evidence and status. Whether these containers are devices in China is being submitted for a written classification opinion; several Southeast Asian markets regulate them as devices requiring local registration.

Usually the width does not change — the length does. KARL STORZ lists 4, 5 and 10 mm scopes in the same 152.4 mm (6″) narrow container; for two scopes up to 10 mm plus a light guide the reference is 469.9 × 152.4 × 76.2 mm at ~310 mm working length. Our six interchangeable insert openings cover this.
Market-dependent. In China this family has no matching catalogue entry and its standards sit in the YY/T 0698 packaging series, so procurement is usually treated as general goods; we are applying for a written classification opinion and will publish it. Several Southeast Asian markets regulate containers as devices.
Weight and visibility: aluminium is about 40% lighter than an all-steel case and PPSU about 60% lighter than stainless while letting staff see the contents. The cost is differential expansion (CTE ≈ 23 vs ≈ 50), which is why sealing must come from silicone compression rather than an interference fit.
Standard sizes accept small batches and first-article validation. Custom tooling plus validation typically takes four to six weeks to first article. Gaskets and inserts are supplied as separate wear parts. Final quantities, prices and lead times are set in the formal quotation.
