Central Sterile Supply Departments (CSSD)

CSSD is where containers live most of the time. Instruments come back from surgery dirty, get cleaned, go into the container, get sterilized, and sit on a shelf until the next case. The container has to survive this cycle hundreds of times per year.

What CSSD managers care about:

• Stackability – shelves are limited. Containers that stack 4 high save space.
• Labeling – each container needs to show what's inside, when it was sterilized, and when it expires. We offer laser-etched ID plates and adhesive label holders.
• Filter replacement – paper filters are cheap but create waste. Reusable filters cost more upfront but save money long-term. Most CSSDs we supply use a mix: paper for high-turnover sets, reusable for specialized sets that don't get opened often.

We offer color anodizing for aluminum containers – different colors for different departments, without the wear issues of paint or stickers.

Endoscopy Repair Shops

Repair shops use our containers for shipping scopes back to customers. A repaired endoscope in a padded aluminum box arrives intact. A repaired endoscope in a cardboard box with bubble wrap sometimes doesn't. We've had repair shops tell us their return-damage rate dropped to near zero after switching to rigid containers.

For repair transport, we make a "scope-only" container: 300mm × 60mm × 50mm, with a silicone cradle that holds one telescope and one light cable. No extra space for things to rattle around.

Anodized Aluminum, Not Painted

Painted aluminum looks good in the catalog. In the autoclave, it doesn't. The heat and pressure cause paint to bubble and flake. Those flakes end up on instruments, in wounds, and in your QA reports. We anodize every aluminum container. It's more expensive to do, but it lasts.

Filter System That Works

The filter keeps the container sterile after autoclaving. If the filter tears or doesn't seal, the load is compromised. Our filter frames are machined aluminum with a silicone gasket that compresses against the container rim. The seal holds at 2 bar pressure differential – more than an autoclave generates.

Paper filters: 0.2 micron rating, single use, pack of 50. Reusable filters: polymer mesh, 0.5 micron, rated for 200 autoclave cycles. We recommend replacing them at 150 cycles to be safe.

Silicone That Doesn't Harden

Medical-grade silicone (Shore A 40–50) stays flexible through repeated heat cycles. Cheap silicone or PVC hardens after 6–12 months and starts cracking. Cracked inserts don't hold instruments properly, and the fragments can contaminate the sterile field.

We had a customer in Turkey who bought cheap silicone inserts from another supplier. After eight months, the inserts were crumbling. They replaced the whole lot with our mats and haven't had an issue in two years.

Internal Layout That Fits Your Set

A container is only as good as what fits inside it. We offer three layout options:

• Standard slot layout – pre-cut slots for common instrument sets (laparoscopy, arthroscopy, ENT). Order by set name, we know the layout.
• Custom cut layout – send us your instrument list with dimensions, we design the mat. One-time tooling fee, then standard pricing.
• Adjustable peg layout – pegs and bands that you reposition as needed. No tooling, but instruments can shift if the pegs aren't tightened.

Most customers start with standard layouts and move to custom once they know what works.

• ISO 13485 – Medical device quality management. Covers design, production, and post-market surveillance.
• CE Marked – For applicable products, compliant with EU MDR.
• ISO 11607 – Sterilization packaging requirements. Our containers with filter systems meet the barrier performance criteria for terminally sterilized medical devices.

Testing we do:

• Autoclave cycle testing – 1,000 cycles at 134°C, 2 bar. Check for discoloration, warping, seal integrity, and silicone degradation.
• Drop testing – Full container dropped from 1 meter onto concrete. No instrument damage, no lid opening, no filter breach.
• Stack load testing – Four full containers stacked for 24 hours. Bottom container shows no deformation.

We keep test reports on file. If your QA department needs them for vendor qualification, we can send copies.

 

 

Before you order, have these details ready:

• What goes inside? – Instrument list with dimensions, or just the set name (laparoscopy, arthroscopy, etc.).
• Sterilization method – Steam autoclave (121°C or 134°C), plasma (low-temperature hydrogen peroxide), or both? Plasma requires different filter materials.
• How many sets do you sterilize per day? – This affects whether you need 5 containers or 50.
• Stacking height limit – Your CSSD shelf height determines how high we can make the container.
• Labeling requirements – Color coding, photo labels, barcode holders, RFID pockets?
• Budget – Aluminum with silicone inserts costs more than wire baskets. If budget is tight, we can suggest a phased approach: start with baskets for high-turnover sets and containers for expensive endoscopes.

Q: Can you make a custom container for my specific instrument set?
A: Yes. Send us the instrument list with dimensions, or mail us the actual set. We design the internal layout, cut the silicone mat, and send you a prototype to test. Once you approve, we go to production. Typical lead time: 3–4 weeks for custom layouts.

Q: Do these work with plasma sterilization?
A: Yes, but you need the right filter. Steam autoclave filters are paper or polymer mesh. Plasma sterilization uses a different filter material (hydrophobic PTFE) because hydrogen peroxide plasma requires gas permeability that standard filters don't provide. Tell us your sterilizer model when you order and we'll match the filter.

Q: Aluminum or stainless steel – which should I choose?
A: Aluminum if weight matters (OR transport, large sets). Stainless steel if you need maximum durability (heavy instrument sets, frequent dropping). Aluminum is about 1/3 the weight of steel. Stainless steel lasts longer but costs more and is harder on your CSSD staff's backs.

Q: What's the minimum order?
A: Standard containers: 10 pieces. Custom containers: 50 pieces for the first order (covers tooling), then 25 pieces for reorders. Repair shops and small clinics can buy single units through our distributor network.

Q: How long do the silicone inserts last?
A: Medical-grade silicone handles 500+ autoclave cycles without hardening. In practice, most inserts last 2–3 years in a busy CSSD. The first sign of wear is when instruments start sliding in the slots – that's when you replace the mat, not the whole container.

Q: Can I get my logo on the containers?
A: Yes. Laser etching on aluminum, screen printing on stainless steel, or adhesive nameplates. Laser etching is permanent – it won't wear off like printing. We need your logo in vector format (AI or EPS). Minimum order for custom branding: 50 units.

Q: Do you sell replacement parts separately?
A: Yes. Filters, silicone mats, locking pins, and lid gaskets are all available as spares. Most customers order a 6-month supply of filters with their initial container order.

Q: What if a container arrives damaged?
A: We pack in corrugated boxes with foam corners. Damage in transit is rare but happens. Take photos of the packaging and the damaged container, send them to us within 48 hours, and we replace it. No arguments.
