And you're probably looking at this for those heat-sensitive items that just can't take a steam autoclave — like flexible endoscopes, fiber optics, or electronics with delicate components, and what it does is use ethylene oxide gas at a mild 50°C with a -60 KPa vacuum to pull sterilant deep into lumens and crevices, which is basically the only way to get true sterility without melting anything or causing corrosion on metals, plastics, or rubbers.
The 23-liter capasity is pretty much the sweet spot for a desktop unit — you can fit a couple of instrument trays or a few scopes in one cycle, but if you're running high-volume OR, you'll want something bigger since each run takes 8 to 12 hours depending on load density and aeration time, and we usually have stock but confirm lead time (check lead time) because demand spikes in flu season.
5 out of 10 buyers who ask about this end up going with a smaller benchtop ethylene oxide unit instead — though honestly, this one's better than reagent grade for the tight control on temperature range form 45 to 55°C, so you don't get those hot spots that can damage optical coatings.
Now on trust — we've been moving these for years and the stainles steel construction holds up well, though I'll be straight with you: the LED digital display isn't fancy but it gives you real-time cycle data and it logs sterilization info automatically, which is one detail a buyer might not think to ask but is critical for your traceability audits since inspectors want to see that recorded temperature and pressure profile.
Certifications are CE, FDA, EEC, and ISO13485 — that's the medical device quality management standard, not just a general ISO, so your compliance officer should be satisfied, and the alarm system catches ultra high temperature events during the cycle, though I've only seen that trigger maybe twice in five years when someone loaded it wrong.
Basically the warranty is 2 years and the MOQ is one unit for most customers, but we'll need a shipping address and your import license for the HS code 84192000 since ethylene oxide sterilizers are regulated in most countries, so roughly 4 to 6 weeks to your dock.
Our MOQ for the SD-H40 is 1 unit, so you can order just one for a single clinic or test it before committing to more.
The SD-H40 is CE, FDA, EEC, and ISO13485 certified. We can share the certificates with your purchase order.
Sterilization runs 8-12 hours at 50°C. The cycle is preset for safety, but you can adjust within the 45-55°C range if needed.
It works on both 220V and 110V, so you can use it in different regions without a separate converter.
The chamber is stainless steel, so it holds up well against corrosion and repeated use in medical settings.
