Getinge HS 22 K7 Benchtop Steam Sterilizer Review: The Gold Standard for Small Clinics?

Running a dental practice, veterinary clinic, or outpatient surgical suite means sterilization isn't optional — it's liability-critical. The wrong autoclave means instrument failure, infection risk, and potential regulatory violations. If you've been researching compact benchtop units and the Getinge HS 22 K7 keeps appearing on your shortlist, this review breaks down exactly what you're getting — and whether the used market price makes sense.

Product Overview

The Getinge HS 22 K7 is a Class B (pre-vacuum) benchtop steam sterilizer manufactured by Getinge Group, a Swedish company with over a century in hospital infection control. This unit is designed for tabletop installation in clinical environments where space is limited but compliance demands are not.

Key Specifications:

• Chamber Volume: 20 liters
• Load Capacity: 7 kg
• Sterilization Class: Class B (EN 13060)
• Cycle Types: Pre-vacuum (fractioned), gravity, and liquid cycles
• Steam Generation: Built-in steam generator
• Temperature Range: Up to 134°C (273°F)
• Dimensions: Compact benchtop footprint (~55 × 45 × 45 cm, varies by configuration)
• Intended Use: Medical instruments, dental handpieces, wrapped/unwrapped loads, hollow instruments
• Regulatory Compliance: CE marked, EN 13060 Class B

This unit competes with the Tuttnauer 2340M and the Melag Vacuklav 43 B+ in the benchtop Class B category. Unlike gravity-only (Class N) units, the HS 22 K7's pre-vacuum cycles make it suitable for sterilizing hollow instruments, wrapped packs, and porous loads — a critical distinction for dental and surgical applications.

Hands-On Experience

Installation and Setup

The HS 22 K7 is a plug-and-play unit in the sense that it doesn't require an external steam supply — the internal steam generator runs off a standard power connection and a distilled water reservoir. Setup involves filling the reservoir, running a test cycle, and performing an initial Bowie-Dick test to validate vacuum integrity.

Expect a qualified biomedical technician to commission the unit if purchasing used — Getinge recommends a service validation after any relocation, and this is standard practice for Class B autoclaves in regulated environments.

Daily Operation

The control panel is straightforward: cycle selection, start, and monitoring displays. Operators select from pre-programmed cycles (134°C 3-minute, 121°C 15-minute, liquid cycle, etc.) and the unit handles the rest. A printout-capable version tracks cycle data for compliance logs — critical for ISO 13485 or Joint Commission audits.

Cycle time from start to dry completion typically runs 30–60 minutes depending on load and cycle type, which is competitive with comparably sized units.

Standout Features

• Fractioned Pre-Vacuum: Removes air in multiple pulses before steam injection, ensuring penetration into hollow instruments (dental handpieces, cannulas, lumened devices) — something Class N autoclaves physically cannot do
• Drying Phase: Active drying prevents wet packs, which can compromise sterile barrier integrity
• Cycle Documentation: Models with integrated printers or RS-232 data logging support audit trails without secondary logging systems

Pros and Cons

Pros

• True Class B compliance — handles hollow, wrapped, and porous loads
• Getinge brand reliability — parts and service networks are well-established globally
• 20L capacity — practical for medium-volume dental or outpatient surgical clinics
• Built-in steam generator — no external plumbing required
• Quiet operation by benchtop autoclave standards
• Strong used market availability — units are regularly serviced and resold

Cons

• Higher initial cost — even used, Class B units command a premium over Class N/S equivalents
• Service dependency — requires qualified technicians; not a DIY-serviceable unit
• Distilled water consumption — requires monitoring and refilling in high-volume environments
• Older firmware on used units — some pre-2015 units may lack USB/network data logging

Performance Breakdown

Who Should Buy This

Ideal for:

• Dental practices running implant placements or surgical extractions where handpiece sterilization requires Class B compliance
• Veterinary surgical suites needing validated sterilization for wrapped instrument packs
• Outpatient surgery centers with moderate instrument throughput (10–30 trays/day)
• Facilities upgrading from Class N units to meet updated regulatory requirements
• Buyers comfortable with the used equipment market who understand service documentation requirements

If your instruments are solid, non-hollow, and unwrapped, a Class N unit will handle your load at lower cost. But if you're sterilizing handpieces, lumened instruments, or wrapped packs, the Class B cycle on the HS 22 K7 isn't optional — it's the standard.

Who Should Skip This

• High-volume central sterile departments — a 20L benchtop unit will bottleneck throughput above ~50 trays/day; look at floor-standing units instead
• Facilities with no biomedical technician access — Class B units need qualified service; this isn't a set-and-forget appliance
• Budget-constrained practices sterilizing only solid instruments — a Tuttnauer 1730M or equivalent Class N unit at a fraction of the price is sufficient
• Buyers who cannot obtain service history on a used unit — unknown maintenance history is a compliance risk

Alternatives Worth Considering

1. Tuttnauer 2340MK (Class N, 23L)

A gravity-cycle unit best for unwrapped solid instruments. Significantly less expensive new and used, with an enormous parts/service network in North America. If your instrument mix doesn't require pre-vacuum, this is a proven workhorse. Find Tuttnauer autoclaves on eBay

2. Melag Vacuklav 43 B+

A direct Class B competitor from German manufacturer Melag. Similar performance envelope to the Getinge HS 22 K7, with a reputation for particularly strong drying performance and a user-friendly interface. Often preferred in German and EU markets. Available through our used autoclaves listings.

3. W&H Lisa B (17L)

A slightly smaller Class B unit popular in dental practices. Lower capacity than the HS 22 K7 but with a compact footprint and strong compliance credentials. Worth considering for single-operatory dental offices. Find W&H autoclaves on eBay

Where to Buy

The Getinge HS 22 K7 is no longer in production, but units are widely available through the used and refurbished medical equipment market. When purchasing, prioritize:

1. Documented service history — at minimum, the last annual validation report
2. Bowie-Dick test results — confirms vacuum system integrity
3. Sellers offering post-sale service or inspection — reputable biomedical equipment dealers, not general resellers

Current listings and pricing:

• Search eBay for Getinge HS 22 K7 autoclaves — marketplace with the widest used inventory; filter by "Tested Working" condition and check seller feedback
• Search Amazon for comparable benchtop autoclaves — for new Class B alternatives in the same category

Expect to pay $1,500–$4,500 USD for a used HS 22 K7 in working condition, depending on age, service history, and included accessories. Units with recent service records and printed cycle validation documentation command premium pricing — and are worth it from a compliance standpoint.

Frequently Asked Questions

Q: Is the Getinge HS 22 K7 a Class B autoclave? Yes. The HS 22 K7 uses fractioned pre-vacuum sterilization, which classifies it as a Class B unit under EN 13060. This makes it suitable for hollow instruments, wrapped packs, and porous loads — the most demanding sterilization requirements in dental and surgical settings.

Q: What's the difference between Class B and Class N autoclaves? Class N (gravity/downward displacement) only reliably sterilizes solid, unwrapped instruments. Class B uses vacuum cycles to remove air before steam injection, enabling sterilization inside hollow instruments (like dental handpieces and cannulas) and through wrapped sterile barriers. Most dental and surgical instruments require Class B.

Q: Can I use tap water in the Getinge HS 22 K7? No. Like all steam sterilizers, the HS 22 K7 requires distilled or deionized water. Tap water causes mineral scale buildup in the steam generator that will damage the unit and void compliance. Use water meeting EN 13060 quality requirements.

Q: How do I know if a used unit is still compliant? Request the most recent annual validation report, Bowie-Dick test records, and maintenance log. Have a qualified biomedical engineer perform a recommissioning inspection before placing the unit in clinical service. Never use an autoclave on patient-care instruments without documented validation.

Q: How does the HS 22 K7 compare to the Tuttnauer 2540EK? The Tuttnauer 2540EK is also a Class B unit with a 23L chamber, making it a direct competitor. The Tuttnauer has stronger North American service support; the Getinge has a stronger European service network. Performance is comparable — the decision often comes down to local service availability.

Q: What accessories should I look for when buying used? Sterilization trays and cassettes specific to the unit, distilled water carboys, a printer (if logging-capable), and ideally the original operator and service manual. Missing accessories are usually sourceable through biomedical supply companies.

Final Verdict

The Getinge HS 22 K7 is a legitimate Class B benchtop autoclave from a manufacturer with serious infection control credentials. For dental practices, veterinary surgical suites, and small outpatient facilities that need to sterilize hollow and wrapped instruments, this unit delivers the pre-vacuum performance that Class N units simply cannot provide.

On the used market with a clean service history, it represents strong value against the cost of a comparable new Class B unit. Just do your due diligence: get the service records, commission a validation inspection, and buy from a seller who understands what they're selling.

If compliance documentation is in order, this is a buy. ```
