Micro volume single channel pipette with newly designed features and reliable accuracy for molecular biology, cell biology lab work. The easily accessible volume adjustment system reduces the time and inconvenience associated with volume selection. The uniquely positioned volume dial is located above the pipette handle, allowing for easy one handed adjustment with the user's thumb. The volume display is located on the side of the pipettor that faces the user. Unlike traditional pipettors, the NextPette does not require a second hand to rotate the pipettor 180° to observe the display. The NextPette also features an innovative, asymetrical designed plunger button that can be rotated to match the comfort preference of the user. This button is freely adjustable to rotate continuously between wide setting, resulting in the more traditional feel of a round, larger diameter plunger button, or to a more narrow (thumb shaped) contour preferred by the majority of researchers. NextPette's materials and components were carefully selected to minimize weight and ensure durability and a long service life. Internal components include precision plungers made of stainless steel (1ul, 10ul, 5000, and 10,000µl models) or ceramic (20ul, 200ul, and 1000ul models) and all use PTFE seals. The pipettors have also been designed with service in mind. They are easy to disassemble, and seals are easy to replace. Silicone lubricant is included with each pipettor.  Recalibration can be done in the lab - no tools are required and the instruction manual includes full details on how to properly check pipetting accuracy and how to recalibrate if necessary. The entire pipettor is autoclavable at 121°C and resistant to UV exposure. All pipettes are factory calibrated in accordance with ISO 8655 standards, and include a factory calibration certificate. The set include one of each and a carousel stand P7700-10 NextPette™ variable volume pipette 0.5 to 10 μl ± 3.8 to 0.5% ± 4 to 0.5% 10 μl P7700-20 NextPette™ variable volume pipette 2 to 20 μl ± 3 to 0.8% ± 3 to 0.8% 200 μl P7700-100 NextPette™ variable volume pipette 10 to 100 μl ± 1.5 to 0.8% ± 1.5 to 0.8% 200 μl P7700-200 NextPette™ variable volume pipette 20 to 200 μl ± 1.2 to 0.6% ± 1.0 to 0.6% 200 μl P7700-1000 NextPette™ variable volume pipette 100 to 1000 μl ± 1.5 to 0.6% ± 1.0 to 0.6% 1000 μl
