A scenario-based guide to buying STERIS equipment—steam sterilizers, surgical tables, fundus cameras, and medical suction units. Written from a hospital purchaser's perspective with honest recommendations.

If you're responsible for buying medical equipment, you've probably searched "STERIS" and found a lot of products. If you're like me, you may have also wondered: which of these do we actually need?

I've managed equipment purchasing for a 150-bed surgical hospital since 2019—roughly $2.8 million annually across 15 vendors. I report to both operations and finance, which means I balance two competing priorities: keeping clinical staff happy and keeping the CFO happy. In that time, I've learned there isn't a universal answer to "what should I buy from STERIS?" It depends on your facility type, your case volume, and what you already have. So let me break it down by scenario.

The Four Scenarios: A Quick Map

Before I dive in, here's the landscape. You're likely in one of these situations:

• Scenario 1: You need sterilization capacity—steam sterilizers, washer-disinfectors, or a full sterile processing department.
• Scenario 2: You're building or renovating surgical suites and shopping for tables, lights, and integration systems.
• Scenario 3: You've been tasked with specialized diagnostics like fundus cameras (the answer here might surprise you).
• Scenario 4: You're asking "what is a medical suction unit?" and whether STERIS makes one you should buy.

Each of these leads to a different recommendation. Let me walk through each one.

Scenario 1: You Need a Steam Sterilizer

If your facility performs any invasive procedures, sterilization is non-negotiable. The question is scale—and that depends on your volume.

Small clinic (1-2 procedure rooms). A compact steam sterilizer, 16-17 inch chamber, can handle a modest daily load. You might also want a small washer-disinfector to clean instruments before sterilization.

Ambulatory surgery center (3-5 ORs). Step up to a 23-inch chamber. And I'd strongly recommend buying a second unit. What I mean is: not a second large sterilizer—just some way to keep processing if one machine goes down. Because eventually, one will. If I remember correctly, we paid roughly $85,000-$120,000 for our 23-inch units (this was in 2022; don't quote me on exact figures). The cost of backup capacity is an insurance premium, not an operational expense.

Full hospital. Multiple large sterilizers, a dedicated sterile processing team, washer-disinfectors, and a tracking system for instrument sets. You're designing a workflow, not just buying equipment.

I didn't fully grasp the backup question until March 2023, when our primary sterilizer went down with a sensor fault. Let me rephrase that: I understood redundancy intellectually. I just didn't think it would happen to us. We spent two weeks shipping instruments out for offsite sterilization—about $14,000 in emergency processing fees, plus the coordination overhead. Everyone on my team had warned me to budget for redundancy. I didn't listen. That's the lesson I now share with anyone who'll hear it: the second unit isn't about utilization; it's about being able to operate on Tuesday morning.

Scenario 2: Equipping a Surgical Suite

This is where STERIS surgical equipment is genuinely at its best. Surgical tables, surgical lights, ceiling columns, and warming cabinets—the ecosystem is engineered to work as an integrated package. And that integration matters more than people expect.

But the right configuration depends on your case mix:

• General surgery: A standard electric surgical table handles the majority of cases. Just make sure the transfer system fits your transport stretchers. (That detail has caused more headaches in our facility than any other accessory.)
• Orthopedics or neurosurgery: You'll want more articulation, radiolucent table sections for C-arm compatibility, and traction accessories. Don't let a rep tell you the standard table does everything.
• Ophthalmology or ENT: Positioning requirements are specialized. Talk to your surgeons before you sign anything.

On lights: I've never fully understood the pricing logic for surgical light heads. I've seen quotes range from $15,000 to $60,000 per light, and the difference isn't always obvious from the spec sheet. My best guess: it comes down to warranty, color rendering, and field depth. Look for a CRI (color rendering index) above 90 for color-critical work. And verify that LED components are covered under the service contract—replacement parts are not cheap.

Anyone who says one surgical table fits all hasn't watched a bariatric case, a trauma case, and a hand procedure happen in the same operating room, in the same week.

Scenario 3: When Specialized Diagnostics Enter the Picture (Fundus Cameras)

Here's a question I hear from procurement folks: "Does STERIS sell a fundus camera?"

The honest answer: no. And you shouldn't buy one from a sterilization company anyway. Fundus cameras are specialized ophthalmic diagnostic devices that photograph the back of the eye. Zeiss, Canon, and Topcon are the specialists in this space—their optics are purpose-built for retinal imaging. When our facility needed one for a new diabetic retinopathy screening program, we bought from an ophthalmology specialist, not a general equipment vendor.

The vendor who told me, "This isn't our strength—here's three companies who do it better," earned my trust for everything else. I'd rather work with a specialist who knows their limits than a generalist who overpromises.

If you're evaluating fundus cameras—and as of January 2025, the market has plenty of solid options—here's your checklist:

• Field of view: 45 degrees is standard for screening programs. Wider options (60-80 degrees) offer more comprehensive documentation but at a higher price.
• Clinical image quality: Read clinical studies, not just marketing specs. Two cameras can have the same megapixel count and produce different diagnostic accuracy.
• Workflow integration: Does it connect to your EMR? Can a tech operate it without a photographer? (My wife works in ophthalmology, and she says ease of use is the #1 overlooked factor—a difficult camera produces poor images regardless of optics.)
• Local service support: If the nearest trained technician is 300 miles away, your device will spend more time down than operational.

Scenario 4: What Is a Medical Suction Unit?

If you've been searching "what is a medical suction unit," here's the quick definition: a device that generates negative pressure to remove fluids, secretions, or debris from a patient's airway, surgical site, or body cavity. It's essential in surgery, emergency care, and post-op recovery.

But the right choice depends on how you'll use it:

• Emergency/transport: You need lightweight, battery-powered, and fast. In airway emergencies, a unit that takes too long to reach target pressure isn't a backup—it's a liability.
• Surgical: Continuous operation, precise vacuum control, and compatibility with sterile tubing and tips. STERIS offers surgical suction products—disposable Yankauer handles and tubing—that integrate with their OR setup, and that integration is genuinely convenient.
• General ward: Simpler units work, but pay attention to flow rate and how easily the canister can be swapped and cleaned between patients.

One practical note: we standardized on one type of portable suction unit for our emergency department and a different solution for the OR. That's not indecisiveness—the clinical requirements are different.

Set Up Your STERIS Login From Day One

This tip is easier to implement than any equipment decision in this article: set up your STERIS login the day the equipment is installed. The portal gives you access to service history, manuals, maintenance schedules, and parts ordering.

Getting access sorted in the middle of a machine downtime is… not fun (which, honestly, is the wrong way to learn that lesson). It takes 20 minutes during onboarding and saves hours of phone tag later. "Experience" is often just another word for having made that mistake before.

How to Determine Which Scenario You're In

If you're still unsure, here's the framework we use internally for every equipment evaluation:

1. List your procedures. The highest-acuity procedure you perform sets your minimum standard. If you're doing implant surgery, you need a validated steam sterilizer and documented processes—AAMI ST79 is the industry standard we reference for sterile processing.
2. Count ORs and average daily volume. This drives sterilizer capacity, table count, and consumables ordering.
3. Ask your biomed team what fails. In our 2024 vendor consolidation project, we spent eight hours with our biomed team asking one question: "What has failed most often, and what's been hardest to repair?" Their answers rewrote our entire capital plan.
4. Calculate total cost of ownership. That's not just sticker price (in other words, include installation, training, preventive maintenance, and projected repairs). A "cheap" sterilizer with annual maintenance costs of $8,000 is more expensive than a $20,000-premium model with a solid service contract.

If STERIS wins on those criteria, buy from them. If a specialist is the better call for a specific product, choose the specialist. The worst purchasing decision is one made on brand reputation alone.

The Bottom Line: Specialists Exist for a Reason

No equipment company is the best choice for everything in a modern healthcare facility. If a vendor claims to be excellent at everything, they are probably not excellent at anything.

STERIS is our primary vendor for sterilization and surgical integration, and I stand by that. But for fundus cameras, we went with ophthalmology specialists. And for portable suction units, we decided based on clinical performance first—not brand preference.

What I've learned in six years of procurement: the strongest partnerships are built on honest boundaries. Ask your vendors what they're not good at. If they give you a straight answer, you've found a partner. If they dodge—well, that tells you something too.
