萊伯特 Biopette Pro手動多道移液器與Labnet Biopette Plus系列多道移液器一樣，革新的回縮系統(tǒng)保證每個槍頭安全密合的插上并防止槍頭卡在桿軸上?；⌒卧O計的槍頭推桿裝置可以使槍頭依次推出，減小退槍頭時所需要的力。

When pipetting liquids which have a viscosity and density different than water, for example organic solvents, a film of liquid is formed on the inside wall of the pipette tip. This film can create an error. Since the film remains relatively constant in successive pipetting operations with the same tip, this error can be avoided by forming the film before transferring the first sample. This is done by aspirating a sample and dispensing it back into the same vessel. Since the film is already formed, all of the following samples will have better accuracy and repeatability. This pre-rinsing operation should be repeated when the volume to be aspirated is changed or when a new tip is used.

• 360°旋轉/推桿裝置，舒適操作，全方wei移液和退槍頭
• 依次退出槍頭，少的推力排除所有的槍頭
• 體積按鈕系統(tǒng)，所需推力減少30%以上
• 人體工程的槍身設計，大手小手輕松把握
• 槍頭桿軸圓潤漸變，每個槍頭都能完美密合

任何移液器都需要定期維護，具體周期視使用狀態(tài)和使用頻率而定。部分組件（比如槍桿）會受到揮發(fā)性蒸氣的影響，需要定期檢查清潔。定期維護清潔可以保持移液器長期高效運轉。萊伯特 Biopette Pro手動多道移液器的設計十分方便日常維護清潔，外表面可以用沾有異丙醇的軟布擦拭，可拆卸的部件也可以用去離子水或者異丙醇清洗。沒有必要把槍桿*拆卸開。先擰下槍頭推桿裝置，再擰下槍桿套。擰下槍桿套后，O型環(huán)和密封圈即自動脫落，方便維護。美國萊伯特手動單道移液器亦是如此。

每一把Biopette Pro系列的單多道移液器都隨槍附贈校準旋鑰，供您在實驗室自行校準。經過質量分析發(fā)現(xiàn)誤差之后，3步輕松完成校準。
