莱伯特 Biopette Pro手动多道移液器与Labnet Biopette Plus系列多道移液器一样，革新的回缩系统保证每个枪头安全密合的插上并防止枪头卡在杆轴上。弧形设计的枪头推杆装置可以使枪头依次推出，减小退枪头时所需要的力。

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°旋转/推杆装置，舒适操作，全方wei移液和退枪头
• 依次退出枪头，最少的推力排除所有的枪头
• 体积按钮系统，所需推力减少30%以上
• 人体工程的枪身设计，大手小手轻松把握
• 枪头杆轴圆润渐变，每个枪头都能密合

任何移液器都需要定期维护，具体周期视使用状态和使用频率而定。部分组件（比如枪杆）会受到挥发性蒸气的影响，需要定期检查清洁。定期维护清洁可以保持移液器长期高效运转。莱伯特 Biopette Pro手动多道移液器的设计十分方便日常维护清洁，外表面可以用沾有异丙醇的软布擦拭，可拆卸的部件也可以用去离子水或者异丙醇清洗。没有必要把枪杆拆卸开。先拧下枪头推杆装置，再拧下枪杆套。拧下枪杆套后，O型环和密封圈即自动脱落，方便维护。美国莱伯特手动单道移液器亦是如此。

每一把Biopette Pro系列的单多道移液器都随枪附赠校准旋钥，供您在实验室自行校准。经过质量分析发现误差之后，3步轻松完成校准。
