賽默飛ST8R離心機使用注意事項

更新時間:2025-11-20      點擊次數:154

一、安全操作核心準則:從源頭規避風險

1. 轉子安裝:精準匹配是前提

Auto-Lock智能識別 :安裝前確認轉子與設備型號匹配(如1000mL大容量轉子僅適配ST8R主機),通過設備面板“轉子ID掃碼"功能自動讀取參數,禁止手動修改轉速/時間上限 (ST8R將強制鎖定安全閾值,如50mL離心管轉子最高轉速≤15,000rpm)。

機械鎖扣到位檢查 :轉子放入腔體后,順時針旋轉至“咔嗒"鎖定聲,手動輕晃無松動;拆卸時需停機至轉速為0,按下“解鎖鍵"后再取出。

2. 樣本平衡:動態穩定的核心

重量差控制在0.1g內 :單組樣本(含離心管)重量偏差≤0.1g,對稱位置放置(如8孔轉子按“1-5、2-6、3-7、4-8"對應擺放)。

利用ST8R動態平衡監測 :設備內置激光傳感器實時監測樣本偏移,偏差>0.1mm時自動降速并報警 ,此時需停機重新調整樣本位置,禁止強行啟動。

3. 生物安全防護:細節決定合規性

BioSeal密封圈必檢 :每次使用前檢查轉子蓋密封圈是否完好(無裂紋、無老化),擰緊時“對角分步"旋緊(如4卡扣按“1-3-2-4"順序),確保氣溶膠泄漏率<0.001% (符合EN 61010防護標準)。

負壓艙體操作規范 :處理生物樣本(如病毒、細菌)時,全程保持艙門關閉,開蓋前等待“解壓完成"提示(約3秒),避免氣流外溢;實驗后立即用75%酒精擦拭艙內及轉子表面。

二、設備維護關鍵要點:延長壽命的科學方法

1. 日常清潔:避免殘留影響性能

清潔部位周期操作方法注意事項
離心艙腔體每次實驗后濕布擦拭(禁用酒精直接噴腔體內部)避免水分滲入電機接口
轉子及蓋每周1次中性洗滌劑浸泡后軟刷清潔金屬轉子禁用強酸/強堿清潔劑
冷凝水排水孔每月1次棉簽清理孔內灰塵確保排水通暢,避免積水結冰

2. 定期性能校準:數據精準的保障

溫度校準(每6個月) :使用ST8R“自校準模式"或第三方溫度計(精度±0.1℃),在4℃、-20℃等常用溫度點測試

轉速校準(每年1次) :通過設備“轉速驗證"功能,對比離心力(RCF)實測值與理論值(公式:RCF=1.118×10??×r×n2,r為轉子半徑,n為轉速),誤差需≤2%。

3. 耗材更換:及時替換防隱患

密封圈(建議1年更換) :BioSeal密封圈長期低溫使用易老化,出現“蓋合不嚴"“異響"時立即更換

減震組件(3年檢查) :設備底部彈簧阻尼基座若出現“運行時位移>5mm",需聯系工程師調整,避免長期振動影響電機壽命。

三、樣本處理規范:確保實驗結果可靠

1. 樣本裝載:細節影響分離效果

離心管選擇有標準 :僅使用耐低溫(-20℃及以下)、耐離心力(≥30,000×g)的專用離心管(如賽默飛CryoTube系列),禁止用普通玻璃管或破損管 (易開裂導致樣本損失)。

液面高度不超80% :樣本體積需控制在離心管刻度線以下(如50mL管最多裝40mL),避免離心時液體溢出污染轉子/腔體。

2. 低溫樣本處理:溫控精準是關鍵

預冷程序不可省 :對溫度敏感樣本(如蛋白、酶制劑),啟動前通過“預冷模式"將腔體溫度降至目標值(如4℃需提前3分鐘),禁止直接放入常溫樣本啟動低溫離心 (ST8R雖支持快速降溫,但驟冷可能導致樣本變性)。

離心后及時取出 :程序結束后3分鐘內取出樣本,避免艙內溫度回升影響穩定性(ST8R“保溫模式"可維持低溫30分鐘,供臨時操作緩沖)。

四、環境與異常處理:穩定運行的外部條件

1. 放置環境:3大基礎要求

水平承重達標 :設備需放置在≥800kg承重的實驗臺,用水平儀校準(四角高度差≤0.5mm),避免傾斜導致振動加劇。

通風散熱良好 :機身兩側及背部預留≥30cm空間,遠離暖氣/空調出風口,環境溫度控制在15-30℃(濕度40%-70%),禁止在粉塵/腐蝕性氣體環境使用 。

2. 常見異常及快速應對

異常現象可能原因ST8R處理邏輯人工操作建議
啟動后報警“E01"轉子未鎖定到位自動停機并提示“檢查轉子安裝"重新旋轉轉子至“咔嗒"鎖定聲
溫度不達標(偏高)密封圈老化/艙門未關嚴持續降溫并閃爍“溫度異常"提醒檢查密封圈,關閉艙門至“鎖定"燈亮
運行時振動過大樣本不平衡/減震組件松動激光監測觸發降速(偏差>0.3mm自動急停)重新平衡樣本,聯系工程師檢查減震

五、智能功能高效應用:讓操作更省心

程序存儲與調用 :通過“自定義程序"功能保存常用實驗參數(如“血清分離:3000rpm/10min/4℃"),下次使用直接調取,避免重復設置導致的參數誤差 。

正確使用的價值:設備性能大程度優化

遵循以上注意事項,ST8R離心機可實現:
實驗數據偏差<1% (NIST標準樣本測試)
年均故障次數<1次 (基于全球用戶3年運行數據)
耗材更換成本降低30% (科學維護延長易損件壽命)
