Labnet's Excel Electronic Pipettes are multifunctional units with operational modes for standard and reverse pipetting as well as multiple and sequential pipetting, mixing of samples and serial dilutions. All functions are easily programmed with one hand on the well positioned display and keypad. A fully motorized piston drive and auto-calibration guarantee excellent accuracy and reproducibilty. A removable, rechargeable Lithium-ion battery ensures many hours of performance between charges.
- Fully Motorized Piston Drive
- Multifunctional with Six Operational Modes
- Virtually Eliminates Pipetting Force
- Exceptional Accuracy and Precision
- Simple, Precise Volume Setting
Rechargeable Electronic Pipette Operation - he body of the Excel electronic pipettes have been designed to fit comfortably in the right or left hand. Along with being lightweight, the unit is also well balanced. The plunger button, located on the back side of the instrument, requires just a small movement of the index finger to activate, reducing the risk of Repetitive Strain Injuries (RSI). The pipette tip ejector slides easily with slight pressure from the thumb. A small, rechargeable, Lithium-ion battery powers the Labnet Excel electronic pipettes. A complete charge is achieved in just eight hours and last for 2000 pipetting cycles. To ensure that a fresh battery is always available, a stand alone charger and extra batteries are available. Also available is a 3 position linear stand for up to three single or multichannel pipettes and a carousel stand for up to six single or multichannel pipettes.

移液管移液管有两种类型.一种只有一个刻度,只能量取一定体积的液体,如25mL.另一种上的刻度和滴定管类似,每小格也表示0.1mL.移液管使用时通常用吸球吸取液体。移液管是吸入溶液的,不是固定的,流出溶液是靠壁流出的;
四字原则:吸 擦 调 放
吸:用吸耳球吸取液体,四指拿移液管,食指扣于移液管上口。
擦:吸取后用滤纸擦干管壁。
调:放松食指使液体流出,调至刻度线,按紧。
放:沿器壁放入所需容器。
垂直是为了保证最后只剩下半滴时,移液管不计算在内的体积。如果移液管上没有写“吹”字,那么最后半滴可以不要。
移液管
用来准确移取一定体积的溶液的量器。移液管是一种量出式仪器,只用来测量它所放出溶液的体积。它是一根中间有一膨大部分的细长玻璃管。其下端为尖嘴状,上端管颈处刻有一条标线,是所移取的准确体积的标志。
塑料类工具灭菌有什么需要注意的吗?谢谢!

一.设定移液体积:1.从大体积调节到小体积时,为正常调节方法,逆时针旋转刻度即可;2.从小体积调节至大体积时,可先顺时针调至超过设定体积的刻度,再回调至设定体积,这样可以保证最佳的精确度。
二.装配移液器吸头:1.单道移液器,将移液端垂直插入吸头,左右微微转动,上紧即可2.用移液器反复撞击吸头来上紧的方法是不可取的,这样操作会导致移液器部件因强烈撞击而松散,严重的情况会导致调节刻度的旋钮卡住。3.多道移液器,将移液器的第一道对准第一个吸头,倾斜插入,前后稍许摇动上紧,吸头插入后略超过O型环即可。
从上理解,
移液枪增量是增加移液体积。
然后往容器中滴液体直至读数为0.70时就可以了
