Siemens Immulite 2000 XPi specifications
The Immulite 2000 XPi isn’t meant to be everything to everyone. It's the refurbished analyzer that does allergy, veterinary, and esoteric testing better than systems costing twice as much. With billions of tests processed since 2009, this platform's reliability is proven beyond question.
Core performance metrics
What actually sets the Siemens Immulite 2000 XPi apart
The allergy testing monopoly.
No other automated immunoassay analyzer in this price range touches the Immulite's allergy capabilities (particularly the 2024 model, but the 2016 is also still highly valuable). While competitors offer basic IgE testing, the Immulite 2000 XPi runs 500+ specific allergens including component testing that distinguishes between true allergy and cross-reactivity. For allergy practices and labs serving allergists, this is the entire business model.
Veterinary testing that others can't match.
The Immulite is one of the only analyzers with validated veterinary endocrine assays. Canine TSH, TLI for pancreatic function, species-specific cortisol, and thyroid panels. Veterinary reference labs can consolidate all endocrine testing on one platform instead of maintaining separate analyzers or sending out.
90-day reagent stability that changes everything.
While other systems at this price point require fresh reagents every 28-30 days, Immulite reagents stay stable for 90 days onboard. For specialty labs running lower volumes of esoteric tests, this means the difference between profit and loss. You're not throwing away half-used reagent wedges every month.

Who's growing the lab with refurbished Siemens Immulite 2000 XPi analyzers?
Allergy testing laboratories
Allergy has exploded. With 40-50% of children now sensitized to at least one allergen, demand for specific IgE testing keeps growing. But insurance reimbursements haven't kept pace. The refurbished Immulite 2000 XPi gives allergy labs the comprehensive testing menu they need at a price that preserves margins.
These labs typically run 30-100 allergy tests daily across dozens of different allergens. The Immulite's ability to keep 138 allergens onboard means no constant reagent swapping. The 90-day stability means low-volume allergens don't expire before use.
Veterinary reference laboratories
Veterinary endocrine testing is booming as pet owners spend more on animal healthcare. But veterinary labs can't justify $200,000 for new equipment when reimbursements are a fraction of human testing.
The refurbished Immulite 2000 XPi is the veterinary endocrine workhorse. Validated assays for thyroid, adrenal, and pancreatic function. Species-specific reference ranges. All at a price point that makes sense for veterinary economics.
Multi-specialty reference labs
Smaller reference labs need to offer specialty testing to compete, but can't maintain separate analyzers for each discipline. The Immulite 2000 XPi consolidates allergy, endocrine, fertility, and tumor markers on one platform.
These labs run 100-300 tests daily across diverse menus. The Immulite's random access capability means thyroid panels, allergy tests, and tumor markers run simultaneously without batching delays.
Hospital laboratories adding specialty menus
Hospitals tired of sending out profitable specialty tests are bringing them in-house. But capital committees won't approve $250,000 for new immunoassay systems. A refurbished Immulite 2000 XPi at 60% less makes the business case easy.
International laboratories
In markets where import duties double equipment costs, refurbished makes the difference between having automated immunoassay capability or staying manual. The Immulite's proven reliability and simple maintenance work in challenging environments.
Why buy refurbished Immulite 2000 XPi analyzers
The specialty testing sweet spot
The Immulite 2000 XPi occupies a unique position - comprehensive specialty capabilities at mid-range throughput. You don't need Abbott Alinity speeds if you're running 200 specialty tests daily. You need an analyzer that handles diverse, low-volume tests profitably.
Technology that's proven, not experimental
The Immulite platform has processed billions of tests since 2009. Every software bug is patched. Every mechanical weakness is documented. Every quirk has a workaround. You're buying mature technology that just works.
The chemiluminescence technology is superior to ELISA but simpler than newer electrochemiluminescence systems. Reliable results without complexity.
The allergy and veterinary monopoly
No other analyzer in this price range offers the Immulite's allergy and veterinary capabilities. If these are your focus, the choice makes itself. Competitors might claim similar menus, but check the actual allergen count and veterinary validation.

Complete Siemens Immulite 2000 XPi FAQ
Refurbished Immulite 2000 XPi analyzers typically run up to 60% less than new, depending on age, condition, and included options. For specialty labs, the ROI is usually under 18 months when you factor in the unique testing capabilities and reagent savings.
With proper maintenance, 7-10 years minimum. Many Immulite 2000 systems from 2009 still run daily. The mechanical simplicity means fewer failure points than newer, more complex systems. We have customers running Immulite analyzers we sold them in 2012.
Absolutely. This is one of the Immulite's biggest advantages. While other systems require fresh reagents monthly, Immulite reagents remain stable for 90 days in the refrigerated compartment. For specialty labs running diverse, low-volume tests, this dramatically reduces waste.
Yes, the system is surprisingly straightforward. The automated daily maintenance runs itself. The software is intuitive. Most techs are comfortable within a week. This isn't like newer analyzers that require specialized training.
Unmatched in this price range. 500+ specific allergens including molecular components. Third-generation chemiluminescence technology provides sensitivity to 0.1 kU/L. If allergy testing is important to your lab, the Immulite is really your only choice at this price point.
Yes, these are true veterinary-specific assays with species-appropriate reference ranges, not human assays with adjusted ranges. The canine TSH, TLI, and thyroid panels are widely accepted in veterinary medicine.
The XPi is the enhanced version with automated sample loading, larger sample capacity, and improved software. Both run the same assays with the same reliability. The XPi adds convenience features that matter in busier labs.
Figure 1,500-2,000 tests in a 16-hour day with typical specialty menus. The 200 test/hour specification assumes optimal conditions. Real-world throughput is about 75-80% of theoretical maximum.
Daily: 15-minute automated startup (runs itself). Weekly: Clean sample probe (5 minutes). Monthly: Check chain oil, clean barcode reader (20 minutes). Quarterly: Full PM (1 hour). It's genuinely one of the lowest-maintenance analyzers available.
Footprint is approximately 6' wide × 3' deep. Add space for computer, printer, and UPS. Include clearance for service access. The refrigerated reagent compartment is built-in, so no separate refrigerator needed.
No, Block Scientific maintains full inventory of all routine and specialty reagents. Even unusual allergens ship quickly. The installed base is huge, so reagent availability will continue for years.
Yes, through standard ASTM or HL7 protocols. Most major LIS systems have existing Immulite drivers. Bidirectional interface allows automatic result transmission and QC tracking.
