實驗用凍干機使用過程中的注意事項

發布時間:2022-07-20瀏覽次數:38返回列表

淺談實驗用凍干機使用過程中的注意事項

  實驗用凍干機適用于生命科學、醫學、食品科學、水產科學、生物化學、環境科學、考古等科學研究,能滿足凍干技術探索和應用的需要。本產品的主要用途是干燥和儲存易脫水的產品。加水后,在不影響生物活性的情況下,可以恢復原材料的性能;

  當產品在很低溫度下干燥時,蛋白質將保持無水,而其他主要化學鍵的質量將保持不變。通過冷凍干燥,使組織、組織提取物、細菌、疫苗、血漿等物質處于干燥狀態,避免酶、細菌和化學物質的變化。冷凍干燥是保存對生物特性敏感的組織的一種好方法。

  實驗用凍干機在使用前一定要先了解下面這些注意事項:

  1、真空泵累計工作時間達到200小時或者真空泵油顏色變成褐色時,必須換真空泵泵油。

  2、冷凍干燥機使用環境溫濕度應保持在10-30℃之間,相對濕度要≤80%。

  3、冷凍干燥機與墻壁的距離應大于30cm,工作環境應無導電粉塵、爆炸性、腐蝕性氣體和強電磁場干擾。

  4、注意凍干機通風緩慢。在微通氣閥旋轉1/2-3/4圈后,你可以感覺到手指的一點點。嚴禁瞬間打開微通風閥,損壞真空傳感器。

  5、請勿頻繁開關總電源和制冷機,制冷機停電后再啟動少需要等待3分鐘。

  6、關機時,應先充氣,然后關閉真空泵,防止真空泵返油污染樣品。

  7、有機玻璃蓋與主機采用硅膠密封圈密封。密封圈應保持清潔,以防劃傷和損壞。有機玻璃蓋不得用有機溶劑擦拭。

  8、凍干機使用完,請把冷阱水分及冷阱阱口水分擦拭干凈。

  實驗用凍干機采用干燥室和冷阱分開設計,采用硅油作為導熱介質,既有利于節能,又有利于加快生產速度(配有電熱除霜),而且清洗方便??筛鶕嶒灮蛏a需要配置自動壓塞功能。
