SpectraLyte-E4E4

• Multi-Biosensor Technology (MBT) — the electrode is maintenance-free, so there is no electrode conditioning in the daily routine.
• Measures Na+, K+, Cl-, iCa2+ and pH by direct measurement.
• 5.6 inch colour touchscreen for quick operation and fast troubleshooting.
• Closed, dedicated reagent pack that is easy to replace, with an inside waste provision.
• Low reagent and low sample consumption — 60–120 µl per sample.
• Stable, robust fluidic system built around an advanced rotary valve.
• Multi-level calibrators and controls secure the accuracy of every result.
• Stores up to 6,000 sample results for easy review.

Three variants share the same platform: the E3 (K+, Na+, Cl-), the E4 (adds iCa2+ and pH), and the E4 AL, which adds a sample autoloader for higher workloads.

• Method: electrochemistry, Multi-Biosensor Technology; direct measurement.
• Throughput: ≥ 100 samples/hour, with each result in about 35 seconds.
• Sample types: serum, diluted urine and aqueous solutions, presented in a sample cup, collection tube, capillary or syringe.
• Sample volume: 60–120 µl.
• Calibration: automatic 1-point calibration with every sample; automatic 2-point calibration every 12 hours or on demand.
• Display: 5.6 inch graphic colour touchscreen; microprocessor controlled.
• Connectivity: 2 × USB-A, 1 × USB-B, 1 × LAN, 1 × RS232; built-in 16-character thermal printer; barcode scanner for sample and patient ID.
• Power: AC 110–220 V, 50 Hz, self-adjusting. Operating range 10–30 °C at ≤ 70% humidity (25 °C).
• Dimensions: 455 × 275 × 480 mm (H × W × D); 6 kg.
• Approvals: ISO 9001, ISO 13485.

Performance — detection range, precision and resolution:

• K+ — 0.50 to 20.00 mmol/L, CV ≤ 1.0%, resolution 0.01
• Na+ — 15.00 to 200.00 mmol/L, CV ≤ 1.0%, resolution 0.1
• Cl- — 15.00 to 200.00 mmol/L, CV ≤ 1.0%, resolution 0.1
• iCa2+ — 0.10 to 6.00 mmol/L, CV ≤ 1.0%, resolution 0.01

The analyser runs on a closed, dedicated reagent pack. Because the biosensor is built into the pack, replacing the pack also replaces the sensing element — there is no separate electrode to condition, clean or replace.

• Closed pack design: no open reagent handling and no manual filling.
• Easy to replace, with waste contained inside the instrument.
• Low reagent consumption per test.
• Multi-level calibrators and control material available for the full parameter set.

Pack sizes differ by model — the E3 pack covers K+, Na+ and Cl-, while the E4 and E4 AL packs add iCa2+ and pH.

Which parameters does the E4 measure?
Na+, K+, Cl-, iCa2+ and pH. The E3 measures K+, Na+ and Cl- only.

How fast is it?
At least 100 samples per hour, with each result in about 35 seconds.

How much sample does a test need?
60 to 120 µl of serum, diluted urine or aqueous solution.

Do the electrodes need maintenance?
No. Multi-Biosensor Technology makes the electrode maintenance-free, and the biosensor is part of the reagent pack.

How many results can it store?
Up to 6,000 samples, reviewable on the instrument.

Can it handle a higher sample load?
Yes — the E4 AL adds a sample autoloader for higher workloads.

How does it connect to our systems?
Two USB-A ports, one USB-B, LAN and RS232, plus a built-in thermal printer and a barcode scanner for sample and patient ID.
