SEMEN TANK MAINTENANCE

Checklist for Optimal Semen Storage & Viability

WEEKLY

• Measure & record LN₂ level (maintain ≥4 inches / 10 cm or per tank specs)
• Log readings to monitor evaporation trends
• Visual inspection: exterior for frost, dents, cracks, or damage
• Check neck plug/cork for tight fit, wear, or frost — replace if needed
• Keep canisters/straws below frost line; remove only one cane at a time
• Ensure tank is stable, elevated, in clean/dry/ventilated area

MONTHLY

• Clean exterior with mild soap & water; dry completely
• Review LN₂ logs for abnormal evaporation patterns
• Inspect canisters, handles, and plug for damage
• Verify semen inventory labels and organization
• Check storage environment (dry, elevated, away from sunlight/traffic)
• Confirm PPE and safety/ventilation equipment ready

YEARLY

• Full review of LN₂ logs and tank performance trends
• Complete semen inventory audit (use FIFO rotation)
• Replace neck plug/cork if worn
• Professional inspection of vacuum integrity & holding time
• Update emergency procedures, staff training, and backup plans
