IntroductionXD236 is an automatic Western Blot system designed for laboratory membrane‑strip assays. It automates temperature, incubation timing and reagent dispensing to support routine Western blot workflows while processing up to 36 strips per run.
Key features- Programmable: ≥38+2 fixed programs; 20 steps × 6 working phases.
- Capacity: supports 1–36 (or 1–30) test strips per run.
- Liquid handling: standard 6‑channel pump, dispensing range 250–3000 μl (1 μl increment); pump accuracy ±3.0% at 2000 μl; precision CV ≤5.0% at 2000 μl.
- Temperature and agitation: selectable room/25/30/37/42 °C; shaker accuracy ±1.5 °C; 3 shaking speeds.
- Contamination control and safety: closed piping system and negative‑pressure suction nozzle reduce cross‑contamination risk.
- Maintenance and consumables: automatic rinsing/cleaning; reagent/wash/waste capacities: reagent 200 ml ×5; wash 1000 ml ×1; waste 2000 ml ×1 (airtight negative‑pressure).
- Interface and alarms: dot‑matrix LCD with backlight, RS232 communication; alarms for reagent dispensing, waste overflow and end of run.
