Technical Specifications
SFRI Vacuum Glass Tubes are designed for use with the ESR 3000 analyzer. Each tube has a total sample volume of 1.28 ml and contains 0.32 ml of sodium citrate solution. The tubes come with labels for easy identification.

Input/Output Interfaces
The device includes an optional barcode interface, a parallel printer interface, and an RS232 port for mono-directional LIS.

Printout and Display
The ESR 3000 features a fast thermal printer using 57.5 mm wide paper with a recording width of 48 mm. It has a 5” LCD touch screen with a monochrome display.

Operating Environment
The analyzer operates within a temperature range of 10°C to 40°C and a maximum humidity of 85%.

Power Requirements
The device requires an A.C. power supply of 110/220 V ±10% at 50 – 60 Hz, with a power consumption of 50 W.

Dimensions and Weight
The dimensions are 300(W) x 180(H) x 400(D) mm, and it weighs 10 kg.

Principles and Measuring Mode
The ESR 3000 uses a photometric infrared reading principle and automatically measures RBC levels every 3 minutes. It supports a 30 min or 60 min correlated modified Westergren method.

Capacity and Throughput
The device can process 30 samples simultaneously with random access and has a throughput of 60 tests per hour in the 30-minute mode.

Accuracy and Reproducibility
The accuracy rate is less than 0.2 mm, with temperature accuracy less than 0.3°C and reproducibility less than 3% or ± 2 mm.

Automatic Temperature Correction
ESR results can be automatically adjusted to a reference temperature of 18°C.

Quality Control
The device supports normal and pathological controls with 9 ml vials.

Memory Storage
It can store up to 200 results per day.

Features and Benefits
The ESR 3000 is an automatic Erythrocyte Sedimentation Rate analyzer that complies with the modified Westergren method. It offers excellent correlation with the Westergren method and allows for random access testing. The device is maintenance-free, user-friendly, and efficient, with a large LCD touch screen and optional barcode reader for easy sample identification. It ensures reliable and accurate results with a reading accuracy rate inferior to 0.2 mm and reproducibility inferior to 3% or 2 mm. The analyzer is designed to simplify ESR analysis, avoiding sample manipulation and reducing the risk of operator infection. It includes a built-in thermal printer for automatic printouts and supports traceability with a mono-directional LIS interface.

Consumables
The ESR 3000 uses high-quality vacuum glass tubes for blood collection, ensuring precise sedimentation rates. The cost of tests is limited to the cost of tubes only.

Quality Control Levels
External controls are specifically dedicated to SFRI controls, while internal controls involve automatic kinetic analysis of sedimentation every 3 minutes.

Practical Features
The device can measure room temperature and automatically convert results to the reference temperature of 18°C, ensuring consistent results across different environments. It can store up to 200 test results per day, with results transferable via LIS to patient files.

Operating Methods
Method 1 allows for random insertion of tubes without referencing, while Method 2 involves identifying a specific well and assigning it a precise tube using a barcode or manual entry.
