Custom Laboratory Instrument Enclosure Solutions
Laboratory instruments require enclosures that can protect sensitive equipment from dust, moisture, chemicals, and electromagnetic interference.
Our precision sheet metal enclosures are designed for analytical instruments, medical diagnostic equipment, control systems, and portable test equipment used in research, pharmaceutical, and industrial laboratory environments.
Custom sheet metal enclosure configurations for analytical instruments, laboratory control systems, diagnostic equipment, and portable test devices.
Every enclosure is manufactured to your specifications, from overall dimensions and cutout layouts to internal mounting structures and surface finishes.
We support projects ranging from single prototypes to volume production, with no minimum order quantity for initial samples.
Material Selection for Laboratory Environments
Choosing the right material directly affects enclosure performance throughout its service life, including corrosion resistance, weight, cleanability, durability, and cost.
Comparison of common sheet metal materials used for laboratory instrument enclosures, including stainless steel, aluminum, cold-rolled steel, and galvanized steel.
| Material | Best Suited For | Key Properties | Typical Applications |
|---|---|---|---|
| 304 Stainless Steel | Standard laboratory environments | Resistant to alcohol, isopropyl alcohol, and mild cleaning agents; compatible with powder coating, electropolishing, and antimicrobial coatings | Environments requiring routine wipe-down disinfection without aggressive chemical exposure |
| 316L Stainless Steel | Wet chemistry laboratories, pharmaceutical cleanrooms, coastal facilities | Higher resistance to chlorides, acids, and concentrated disinfectants such as sodium hypochlorite and hydrogen peroxide; electropolished 316L can provide a mirror-like, low-particle-retention surface | Environments with frequent chemical exposure |
| 5052 Aluminum | Portable instruments, wall-mounted analyzers, handheld devices | Lightweight with excellent formability; anodizing creates a hard, wear-resistant surface with minimal additional weight | Weight-sensitive applications |
| 6061 Aluminum | Installations requiring higher structural strength while remaining lightweight | Higher structural strength than 5052 and can be heat-treated for increased hardness | Enclosures supporting heavier internal equipment |
| Cold-Rolled Steel (SPCC) | Fixed installations such as benchtop analyzers, control consoles, and stationary measuring equipment | Excellent balance of strength, cost, and manufacturability; powder coating provides reliable general corrosion protection | Applications with limited chemical exposure and no strict weight requirement |
| Galvanized Steel (SGCC) | General laboratories with moderate environmental exposure | Zinc coating provides basic corrosion resistance at relatively low material cost | Temperature-controlled laboratories using standard cleaning agents |
Cost Considerations:
- 316L stainless steel typically costs approximately 30–50% more than 304, making it most suitable where enhanced chemical corrosion resistance is required.
- Aluminum raw material generally costs 15–25% more than cold-rolled steel, but its lower weight can help reduce international shipping costs.
- For enclosures that do not require high-level corrosion resistance, powder-coated cold-rolled steel is usually the most cost-effective option.
- Surface finishing typically accounts for approximately 15–30% of total enclosure cost. Electropolishing costs more than powder coating but can reduce post-installation cleaning requirements in cleanroom environments.
Main cost drivers for custom laboratory enclosures, including material, fabrication, surface finishing, sealing, and inspection.
During the DFM review, our engineers will recommend the most cost-effective combination of material and surface treatment for your application.
Protection and Sealing Solutions
Laboratory environments present specific challenges, including chemical splashes, humidity changes, cleaning and disinfection procedures, and airborne particles.
Our enclosures use precision sealing systems to provide reliable environmental protection.

| IP65 | Dust-tight | Protected against water jets | Pharmaceutical and chemical laboratories |
| IP66 | Dust-tight | Protected against powerful water jets | Heavy washdown environments |
| IP67 | Dust-tight | Protected against temporary immersion | Outdoor installations and flood-prone areas |
| IP68 | Dust-tight | Protected against continuous immersion | Submersible applications |
Gasket Material Options
| Gasket Material | Temperature Range | Best Suited For |
|---|---|---|
| Silicone | -60°C to +200°C | Most laboratory environments requiring good flexibility across a wide temperature range |
| EPDM | -40°C to +120°C | Outdoor or UV-exposed applications requiring good weather resistance |
| FKM (Viton) | -20°C to +200°C | Aggressive chemical environments requiring excellent chemical resistance |
| Neoprene | -30°C to +100°C | General industrial environments requiring balanced overall performance |
| Conductive Silicone | -55°C to +175°C | Applications requiring both IP sealing and EMI shielding across enclosure seams |
Each enclosure is tested for proper gasket compression to verify sealing performance.

EMI/RFI Shielding Levels
| Shielding Level | Method | Typical Attenuation |
|---|---|---|
| Standard | Shielding provided by the metal enclosure itself | 20–40 dB |
| Enhanced | Conductive seam gaskets + internal shielding coating | 40–80 dB |
| Fully Shielded | Conductive gaskets + shielding coating + shielded compartments + optimized grounding | 60–100+ dB |
Actual shielding performance depends on frequency range, opening design, connector interfaces, and gasket compression.
