Serological pipettes are also called disposable pipettes, which are mainly used to accurately measure a certain volume of liquid and need to be used together with a suitable pipette. As a laboratory disposable consumable, it has the following characteristics:
1. Transparency: The raw material of serological pipettes is generally polystyrene (PS), which has good transparency, is light in weight, and is not fragile. Tubes made of this material are easy to transport and can also be cleared transparently. Look through the tube to see the specific volume of the solution.
2. Various specifications: The common specifications of tubes are 1.0ml, 2.0 ml, 5.0 ml, 10.0 ml, 25.0 ml, 50.0mL, and 100ml. According to different experimental requirements, you can choose the appropriate specification.
3. The tube body has scales: The tube body has accurate scales for easy observation and reading. Positive and negative double scale design, convenient for adding and subtracting samples; negative scale design, provide a certain extra sampling capacity.
Serological Pipettes4. Sterility: Serological pipettes are widely used in tissue culture, bacteriology, clinical, scientific research experiments and other fields that require aseptic operation to transfer liquids. In order to ensure the sterility of liquids, this consumable must also be sterilized. To meet the requirements of no pyrogen, no endotoxin and no cytotoxicity.
5. Color marking: In order to better distinguish the specifications of different products, in addition to the different precision scale marks on the tube body, different color rings are used to mark different capacity specifications at the end of the tube, which is more convenient for identification and use during work.
The above are the characteristics of serological pipettes. When using this consumable, it is necessary to match the corresponding pipette to realize work automation and improve work efficiency.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
