冷冻干燥机
仪器介绍
Labconco™ FreeZone™ Triad Freeze Dryer是一款三合一的冻干机。可以进行预冷冻，使用烧瓶或在架子上进行冻干，并在真空下封口。左侧设有四个样品阀，可进行封口托盘干燥和样品冷冻干燥。两种类型的样品冻干可以同时进行。冷冻室对样品进行预冷冻，节省资金和时间，消除了单独冰箱和产品转移的需求。
参数
| Collector coil | Stainless steel collector coil capable of removing 1.84 L of water in 24 hours and holding 2.5 L of ice before defrosting |
| Cooling and heating | Two 1/3 hp HCFC/CFC-free refrigeration compressors cool the collector to ≈-85 ° C (≈-121 ° F) and work in concert with a 1000-watt heater to cool and heat fluid medium circulating through channels in the shelf. Temperature ramp and hold programming from ≈-55°C to ≈+50°C (≈-67 ° F to ≈+122 ° F) and ≈-75 ° C (≈-103 ° F) during pre-freezing. Not for use with samples containing methanol or ethanol. |
| Defrost | Hot gas defrost with stainless steel drain pan, silicone drain hose and auto shut off at +60 ° C (+140 ° F) |
| Vacuum pump evacuation efficiency | ≥ 189 L/min, ultimate vacuum ≤ 7 x 10^-3 mBar Screen: Full color, 5" capacitive touch screen with Lyo-Works OS |
| Stoppering | Pneumatic stoppering mechanism with diaphragm and plate. No compressed gas is required. |
