How Does A Pipette Become A Routine Laboratory Instrument?

Can you believe that pipeting has changed the scientific world and protected millions of scientists?This is a bit of an exaggeration, but if you look at the laboratory before the invention of the pipette and see how the scientists operated, you'll nod in agreement.

Most of you who took lab classes as students have used rubber cap droppers.A simple pinch on the top of the cap will suck the liquid from the container below into the dropper, loosen it and let it flow back.This method can also be called pipetting, but it is too crude to control the amount of liquid absorbed, which does not meet the requirements of scientific research for accuracy.As a result, someone took inspiration from a straw and thought of using a straw to drink a drink.Researchers began using graduated glass tubes with one end in the mouth and the other end inserted directly into the liquid.As long as you look at the scale, you can suck as much as you want, which is a lot more accurate.But what about the liquids used in the lab?If you're lucky, you might inhale something harmless and make only a few trips to the bathroom.If you're unlucky, you suck in the toxic stuff, and you're bad.Indeed, it was found that as of 1915, about 40% of laboratory infections were caused by pipettes.So much so that to this day, some laboratory safety practices and tests have repeatedly banned the use of mouth pipette.Still, some experimenters still like to keep their mouths shut, such as in countries that dance when they disagree.

At this point, the reader can already understand why some people say that pipestors change the scientific world and protect researchers.However, this great invention is actually not very old. It entered the laboratory only fifty or sixty years ago.The pipeting device first appeared in 1956 and was invented by Heinrich Schnitger, a physicist at the German Institute of Physiological chemistry.The micropipette he has designed has all the characteristics required by modern micropipettes.In a follow-up work, he also developed chromatographic samples with a volume of less than 1 ml and published his invention as a patent.In 1958, he teamed up with the German company Eppendorf, which introduced the push-button micropipette, becoming the first company in the world to produce micropipettes.Eppendorf has been successful on the road to commercial pipette development with the development of an interchangeable pipette head made from polyethylene and polypropylene.Today, the Eppendorf company remains active in laboratory instruments, with its pipettes and automated pipettes systems playing an important role in the global and Chinese markets.While The Eppendorf company continued to study and improve the pipette, Labsystem company of Finland invented multi-channel fixed range pipette, which greatly improved the efficiency of pipette operation and thus joined the battle of the pipette market.Today, Labsystem has become a subsidiary of The "acquisition monster" Seymour Fisher Scientific, and the sales volume in the multi-channel pipefitter market is still the no.1 all year round.In the Chinese market, the Share of Finnish Leiber pipett is also very high, which is very common in various laboratories.In addition, at about the same time, in the 1970s, France's Gilson also launched the Pipetman, the first single-channel adjustable range pipette, which won the reputation of "the world's first gun".With the advantages of high accuracy, high accuracy, stability and durability, Pipetman has gained momentum in the global market, and even once firmly occupied the no.1 position.

The development of pipettes has come by leaps and bounds from the late 1960s, to the 1970s, and now to automation.In addition to the above mentioned brands, CAPP of Denmark, RAININ of the United States and other manufacturers have also gradually developed their own pipeting products to take a share in the market.Domestic brands, on the other hand, mainly copy imported products. Although they are cheap and fine, they have no right to speak due to the lack of independent technology.Some domestic manufacturers even under the name of imported brands, with the domestic origin of pipette products posing as.In the future, the domestic laboratory instrument market will be larger, and the demand for pipettes will not be less.Industry insiders believe that users will be more inclined to lower prices, higher accuracy, more powerful functions, more attention to humanized pipeting products.From the design of the core structure, to the assurance of the overall quality, to the grasp of the product details, the instrument manufacturers need to invest more energy to study.Domestic instrument manufacturers should seize the opportunity, firmly consolidate their advantage of high cost performance, toward the high-end pipett market.
