The ESR (Erythrocyte Sedimentation Rate) tube assembly production line is a highly automated system specifically designed for manufacturing blood sedimentation tubes used in ESR testing. Integrating key processes—including flexible tube loading, precise liquid dispensing, efficient drying, intelligent capping, vacuum stoppering, and offset tray loading—the line enables fully automatic output from empty tubes to finished products, requiring only one skilled operator to meet full production demands.

1. Flexible Tube Loading: Track-based drop mechanism loads 10 tubes per cycle without damaging labels, ensuring stable and reliable placement.
2. Triple Liquid Dispensing Systems: Dedicated systems for anticoagulant (3.8% sodium citrate), atomized anticoagulants (e.g., K₂/heparin), and clot activators, featuring high-atomization nozzles and ultrasonic auto-cleaning.
3. Dual Drying Stations: PTC rapid heating with precise temperature control via solid-state relays; each station operates independently for uniform coating drying.
4. Smart Capping & Vacuum Stoppering: Dual safety design (mechanical cap pickup + vacuum suction) combined with servo-proportional vacuum control ensures excellent sealing and stability.
5. Offset Tray Loading: Tubes are directly loaded into foam trays after offset positioning—no intermediate handling required.

1. High Automation: Only one operator needed, significantly boosting productivity;
2. Modular Design: Compact footprint, high standardization, low maintenance;
4. Precision Control: Dispense volume, temperature, and vacuum level are all programmable via touchscreen for excellent repeatability;
4. Wide Compatibility: Supports standard φ8×120mm ESR glass tubes (75/100 universal);
5. Robust Construction: SUS304 stainless steel frame with welded structural base offers high rigidity and vibration resistance.

This production line is tailored for the medical consumables industry, serving hospital laboratories, third-party diagnostic centers, and IVD (In Vitro Diagnostic) manufacturers. It mass-produces standardized glass ESR tubes pre-filled with 3.8% sodium citrate (blood-to-anticoagulant ratio 4:1), widely used in the auxiliary diagnosis of inflammatory conditions, infections, rheumatic diseases, and malignancies.
