賽默飛ST1R Plus臺式冷凍離心機:科學養護指南

更新時間:2025-11-19      點擊次數:144

在追求高效與精準的實驗室中,賽默飛世爾科技ST1R Plus臺式冷凍離心機是您分離珍貴樣本不能缺少的伙伴。為確保其時刻保持最佳性能,產出可靠數據,并為您的科研投入帶來長久回報,科學的日常維護與定期保養 至關重要。這份簡潔的養護指南,助您守護實驗利器。

日常清潔:潔凈是性能的基礎

離心腔清潔:

每次使用后,特別是處理過可能泄漏或產生氣溶膠的樣品后,務必 關機并拔掉電源線。

使用柔軟、不起毛的濕布(可蘸取中性溫和清潔劑稀釋液或實驗室專用清潔劑)擦拭離心腔內部、轉軸和橡膠密封圈,完整清除 殘留的液體、鹽分或污漬。

關鍵提示: 避免使用強酸、強堿、有機溶劑(如丙酮、乙醇需謹慎,確認兼容性)或研磨性清潔劑,防止腐蝕腔體表面或密封件。切勿直接向腔體內大量噴淋液體 ,防止滲入電氣部件。清潔后確保腔體完整干燥(可用干凈干布擦拭)。

轉頭(轉子)與適配器清潔:

將轉頭從離心機中取出。仔細檢查 轉頭孔穴、適配器、吊籃和蓋子,清除所有可見殘留物。

使用溫和清潔劑和軟布/軟刷小心擦洗。用大量清水沖洗干凈(確保清潔劑無殘留)。

完整晾干 (推薦自然風干或用無絨布擦干)后,方可重新安裝或存放。絕對禁止 將未完整干燥的轉頭安裝回離心機。

外部表面清潔:

使用濕布擦拭儀器外殼、控制面板和艙門外部,保持設備外觀整潔。避免水滴滲入面板縫隙或通風口 。

定期保養與檢查

生物凈化(如適用):

根據實驗室生物安全要求和實際接觸樣品的風險等級,定期 對離心腔和轉頭進行生物凈化 處理。請嚴格遵循實驗室規定的凈化流程和推薦的、經認證對設備材質安全有效 的凈化劑進行操作。

轉頭檢查與維護:

每次使用前 :肉眼仔細檢查轉頭(特別是吊籃式轉頭)、適配器、蓋子和O型圈(如有)。重點查看 是否有裂紋、變形、腐蝕、過度磨損或老化跡象。任何損傷都必須停用該部件!

定期檢查 :遵循轉頭說明書建議的壽命和使用次數限制。即使外觀完好,達到最大使用次數或年限后也應及時更換 ,確保安全。

正確存放 :清潔干燥后,將轉頭倒置 存放于干燥、無塵環境中,避免長期受壓變形。

排水維護(如配置):

ST1R Plus制冷系統在運行中可能產生少量冷凝水。確保設備放置平穩,并定期(建議每1-3個月,或根據使用頻率和環境濕度調整)檢查并清潔位于設備底部或后部的冷凝水排放口/蒸發盤 ,防止堵塞影響排水或制冷效率。請查閱用戶手冊確認具體位置。

通風保障:

始終保證 設備周圍(尤其是背部通風口)有充足的空間 (建議至少10厘米)。切勿 用物品覆蓋通風口或緊貼墻壁放置。定期 用軟刷或吸塵器清除通風口格柵上的灰塵,確保散熱良好,這對壓縮機壽命和制冷效率至關重要。

使用規范:

平衡至上: 嚴格遵循平衡規則! 確保對稱位置的樣品管重量相差不超過說明書允許的極小范圍(通常≤0.1g)。使用天平精確稱量填充物(如水、緩沖液)。不平衡運行是轉頭損壞甚至安全事故的最大誘因。

規范操作:

仔細檢查并蓋緊樣品管蓋或適配器蓋,防止運轉中液體溢出。

選擇合適的轉頭和適配器,確保樣品管適配且不超過最大容量。

設定參數(溫度、轉速/RCF、時間)不得超過 轉頭和適配器的額定極限值。

運行結束后,待轉子完整停止 且溫度回升接近室溫(或按提示),再打開艙門取出樣品。避免溫度驟變可能產生的冷凝水。

耗材選擇: 強烈建議使用 賽默飛原廠或經認證兼容 的轉頭、適配器和耗材(如離心管)。非兼容耗材可能導致不平衡、破裂或性能下降。

異常處理: 運行中如遇異常噪音、劇烈震動、錯誤報警或溫度失控,立即按Stop鍵停機! 排查原因(如不平衡、轉頭損壞等),解決后方可繼續使用。記錄并報告持續性問題。

專業護航:年度維護與支持

校準服務: 為保證離心分離的可靠性與重現性,建議 每年或按實驗室質控要求,由賽默飛授權工程師 進行專業的轉速、溫度及計時精度校準。

全面檢查: 定期(如每1-2年)進行專業維護檢查,工程師將全面檢測電氣安全、制冷系統、控制系統核心部件狀態,進行必要維護,防患于未然。

GF支持: 始終通過賽默飛世爾科技GF渠道獲取耗材、配件、維修和技術支持服務,確保穩定可靠。

結語:精心養護,價值恒久
