  • UV/Cross-Contamination Prevention: Use filter pipette tips; perform setup in designated pre-PCR and post-PCR areas; use UNG (uracil-N-glycosylase) for carryover prevention when indicated.
  • Ventilation: Ensure adequate ventilation; unit generates heat during operation; do not block ventilation openings; place in well-ventilated area.
  • Sample Tube Compatibility: Use only PCR-grade tubes, strips, or plates rated for thermal cycling; ensure proper sealing to prevent evaporation and sample loss.
  • Load Limits: Do not exceed 96-sample capacity; load tubes or plates symmetrically for optimal thermal performance.
  • Firmware/Software Updates: Use official manufacturer updates only via USB or LAN; verify compatibility before updating .
  • Training: Only trained laboratory personnel should operate the TC1000-G-Pro for clinical diagnostic applications.

2. FIRST AID MEASURES
