更新時間:2025-11-21      點擊次數:203

隨著生命科學研究向微量、高通量、高靈敏度的方向發展,對樣本處理設備,特別是離心設備,提出了更高要求。實驗需要在低溫環境下快速、溫和地分離微量液體(如 PCR 反應液、細胞裂解液、核酸/蛋白提取物),同時確保設備易于操作、節省空間且運行安靜,以維持良好的實驗室環境。賽默飛世爾科技 Fresco21 冷凍型微量離心機正是為滿足這些精準需求而設計的先進儀器。

2. Fresco21 冷凍型微量離心機的核心優勢與技術亮點

2.1 高效精準的制冷系統

快速制冷與穩定控溫: Fresco21 采用先進的高效壓縮機制冷技術,可在短時間內達到設定溫度(低至 -11°C),并能精確維持腔體內部溫度均勻穩定(±1°C),有效保護對溫度敏感的樣本(如酶、RNA、不穩定蛋白)在離心過程中的活性與完整性。

預冷功能 (Pre-cool): 用戶可提前啟動預冷程序,使離心腔快速達到設定低溫,確保樣本在放入瞬間即處于理想處理環境,大程度減少溫度波動對實驗結果的影響。

2.2 靜音與低振動設計

靜音運行: Fresco21 通過精密的轉子動平衡設計、優化的驅動系統和隔音材料應用,實現了極低的運行噪音水平(<50 dB)。這對于需要集中思考的實驗環境(如測序中心、細胞房)或開放共享實驗室尤為重要,顯著改善工作舒適度。

平穩運行: 先進的電機驅動和智能控制系統確保設備啟動、運行和停止過程異常平穩,有效降低機械振動對樣本(如細胞沉淀)的擾動,提高分離效率和沉淀物緊實度。

2.3 靈活高效的處理能力

微量樣本處理專家: 標配多種高性能轉子及適配器,兼容主流規格的 PCR 管(0.2 mL, 0.5 mL)、PCR 條(8聯管)、96孔和384孔PCR板,滿足從單管快速離心到高通量板式離心的多樣化需求。

強勁性能: 最高轉速達 21,130 rpm (約30,000 x g),可快速有效地完成微量液滴收集、細胞/微珠沉淀、核酸/蛋白沉淀等關鍵步驟,大幅縮短實驗周期。

快速轉頭更換: 人性化的免工具轉子鎖定系統,使轉子更換操作簡便快捷,提升工作效率。

2.4 直觀智能的用戶體驗

用戶友好界面: 清晰、直觀的 LCD 顯示屏結合簡潔的按鍵布局,使得溫度、轉速、時間、離心力 (RCF/RPM 一鍵轉換) 等參數設定一目了然,操作簡單易學。

程序化操作: 支持存儲常用程序,方便快速調用,確保實驗條件的一致性。

安全可靠: 具備自動門鎖、不平衡檢測、超溫保護、超速保護等多重安全機制(符合相關國際安全標準),確保人機安全。轉子識別功能防止超速使用。

2.5 緊湊的臺式設計
Fresco21 擁有精巧的體積,占用極小的實驗室臺面空間(如置于超凈工作臺或通風櫥內),特別適合空間有限的實驗室環境,優化實驗室布局。

3. 廣泛的生命科學應用場景
Fresco21 冷凍型微量離心機在眾多領域發揮著關鍵作用:

分子生物學: PCR/qPCR 反應體系的配制與離心、DNA/RNA 純化與沉淀、酶切連接反應。

細胞生物學: 微量細胞沉淀、去除培養基上清、細胞裂解物離心澄清。

蛋白質研究: 蛋白沉淀、免疫沉淀 (IP) 后清洗、上清/沉淀分離。

測序與芯片: NGS 文庫制備中的各步純化與離心。

臨床診斷: ELISA、分子診斷樣本的前處理。

通用實驗室: 任何需要快速、低溫、微量離心的場景。

4. Fresco21 如何提升實驗室價值

保障數據可靠性: 穩定的低溫環境和優異的分離效果確保樣本完整性,為下游實驗結果的準確性和可重復性奠定堅實基礎。

提升工作效率: 快速制冷、強勁離心力、高通量處理能力(板式轉子)、簡便操作顯著縮短樣本處理時間。

優化實驗室環境: 靜音設計創造更舒適、干擾更少的工作空間。

節省寶貴空間: 小巧機身適應各種實驗臺配置。

降低總持有成本: 可靠耐用的設計、便捷的維護以及賽默飛全球化的服務網絡支持,確保設備長期穩定運行,降低運營成本。

5. 結論
賽默飛世爾科技 Fresco21 冷凍型微量離心機集高效制冷、靜音運行、強勁靈活的微量處理能力、用戶友好操作及緊湊設計于一身,代表了現代生命科學實驗室對低溫微量離心設備的高標準要求。其性能在保障樣本活性、提升實驗效率和結果可靠性方面具有顯著優勢,是研究人員進行高質量科學研究的有力工具。選擇 Fresco21,意味著選擇了一個值得信賴的高性能低溫樣本處理解決方案。
