A pipette, also known as a pipette gun, is a device used to quantitatively transfer liquids. When conducting research in analytical testing, a small or trace amount of liquid is generally removed with a pipette. Pipettes can be divided into gas piston pipettes (Air-displacement pipette) and external piston pipettes (Positive-displacement pipette) according to the principle. Gas piston pipettes are mainly used for standard pipetting, and external piston pipettes are mainly used to handle special liquids such as volatile, corrosive and viscous. Many people ignore the correct use of pipettes and some of the details.

The National Development and Reform Commission encourages investment in new energy industries to have different treatment
The revised "Guidance Catalogue for Industrial Structure Adjustment" (2011) (hereinafter referred to as "Catalogue") was introduced recently. This catalogue represents the new orientation of the industrial restructuring of the "Twelfth Five-Year Plan". In this new catalogue, the new energy industry as a strategic emerging industry is listed as a new category of encouragement, which is also the case for the specific industry plan such as the “New Energy Industry Development Planâ€. The latest will manifest. However, the “treatment†of different industries in the new energy category is quite different. This revision is more detailed. The new energy item contains 10 sub-items, including solar energy, biomass energy, wind energy and ocean energy. Among them, there are 5 items for biomass energy development, 4 for solar energy development, and 1 for ocean energy. Wind energy and ocean energy have only been used to encourage the development and application of complementary technologies for electric and photovoltaic power generation and the development of marine energy and geothermal energy utilization technologies and equipment manufacturing. There is no more mention. Compared to the two editions of the Catalogue in 2005 and 2007, the new edition of the Catalogue has undergone major changes, but the “Nuclear Power Plant Construction†entry has not changed. In this regard, people close to the NDRC told reporters that this is only the direction of policy encouragement and guidance, and does not mean that they do not support their development without entering the encouraged category.
