Product Description:
Graduated glass dropper for the laboratory commonly used glass measuring instruments, usually made of soda-lime glass, a complete pipette should have a dividing line, nominal capacity, type marking, standard temperature (20 ℃), accuracy level, trademark or factory name and other markings!
Product Features:
1. Accurate measurement of chemical reagents: In chemical experiments, such as acid-base titration, pH determination, etc., it is necessary to take the exact amount of liquid for calculation. Therefore, the graduated pipette becomes a necessary tool in various precision operations.
2. Measurement of biological liquids: In medical or biological experiments, it is often necessary to measure the volume of biological liquids such as blood, urine, etc., and the graduated pipette is also an indispensable equipment at this time.
3. Auxiliary micro-experiment: for some tiny experiments, measuring cups and other large containers can not meet the requirements, at this time the graduated pipette can be used as an auxiliary tool, such as microcentrifugation, microbiology microbial counting and so on.
In addition to the above use scenarios, graduated pipettes can also be used in conjunction with other devices, such as gas chambers, centrifugal tubes, etc., in order to achieve a more complex use of the effect.

Product Details:
1. Do not exceed the scale: Since the scale in the pipette is precisely marked, each pipette has a maximum volume limit. Do not exceed the scale as this will affect the accuracy of the results.
2. Be careful with aspiration: care should be taken when using pipettes so that once the liquid has been aspirated, no air should be contained below the scale markings, as this will also adversely affect the results of the experiment.
3. Uniformity: A uniform standard should be used in the selection of the amount of liquid to be taken to ensure accuracy. In general, it is recommended that half of the liquid volume be selected as the standard.
