Upright Mechanical Cryogenic Freezer (−150°C)

立式机械式低温冷冻箱（−150°C）

Vapour-phase temperatures without handling nitrogen every day: that is the case for this upright mechanical freezer. It reaches −100°C to −150°C in 300–600 L, holding 20,000–40,000 vials, with ±5°C uniformity. Energy use is 10–20 kWh/day, pull-down 6–10 h, and the room must stay within 16–32°C.

Temperature range: −100°C to −150°C
Capacity: 300–600 L
Storage (2 mL vials): 20,000–40,000 vials
Temperature uniformity: ±5°C
Pull-down time: 6–10 h from ambient
