The Effective Laboratory Utensil Micropipette
Laboratory micropipette, made up of glass material which is used in minor liquid measurements. The team has transformed measurement work in the laboratories of chemistry, biochemistry, biology molecular, cellular due to its speed, simplicity, efficiency and elegance.
✨History of micropipettes
The laboratory micropipette is necessary its definition which is a laboratory instrument. Which can be glass or plastic, with which measurements of liquid volumes are made in small proportion. The place where it was manufactured and used was at The Carsberg Laboratories in Denmark.
In the vestiges of history it is verified that at the end of the XVII century the pipette was patented by Louis Pasteur. Which were simple, glass, cylindrical in shape with a rubber that sucked the liquid by vacuum. In other words, the history of the pipette is intimately linked to that of the micropipette.
It turns out that 200 years ago the instrument existed. In the Moderna the pipette was already used. The first patented pipette was made in the United States of North America in 1924. Some time after 1957 the creation of the adjustable pipette was recorded by the post doctor Heinrich Schnitger in Germany.
When his physician son Heinrich Nether died, he re-founded the Eppendor company and began commercial production of the instrument in 1961. On the other hand, in 1974 a group of professors from the University of Wisconsin in Madisonville. It gave rise to the creation of an adjustable pipette patented in the year 1974 by Warren Pipetman Gilson and Henry Lardy.
But the apparatus presented drawbacks in the necessary strength for its use and possessed low temperature resistance. It was in the year 1980 when a variety of models were implemented to solve the existing limits. Proposing the use of a spring mechanism.
They are currently still used apart from the fact that others have been created with biotechnology.
✨Who created the micropipette?
The laboratory micropipette its creation is attributed to the post doctor Heinrich Schnitger, born in Germany. Motivated by repetitive execution, in the handling of the instrument for a long time. The pipetting of small volumes of liquids becomes repetitive.
I invent the utensil under the design of a piston model with a removable plastic tip spring. These characteristics are combined with current pipettes.
✨What is a laboratory micropipette?
Laboratory micropipettes are a type of object whose function is to absorb, suck and transfer small volumes. Very useful for handling any kind of liquid because its tip can be discarded. It is a volumetric instrument that measures an aliquot of liquid which can be made of glass.
It is used with different techniques in analytical chemistry, its capacity may vary depending on the model, usually 20, 200, 1000 microliters (maximum) are achieved. While the minimum capacity is 0.2 microliters. For its use, it is not necessary to change the instrument.
Because it employs disposable ends classified in, yellow with volume of 10 uL. Blue, for volume of 800 uL. It is a tool widely used in any type of study in all laboratories around the world. It also includes various members in a particular way with specific measures to be poured.
They are recognized due to their special shape with a plunger as identification data. They use disposable tips, they also transfer any type of solutions to Pietri plate or capsule. Different analyses are performed with them, obtaining supernatant cells in liquids.
The device is used daily in places where chemistry is studied, drugs are discovered, biology, forensic sciences, pharmacists. They all exist operating on the same principle. They are calibrated from the factory under international standards. It is fast, convenient, elegant, simple, simple and effective
✨How is the micropipette used?
For the use of the micropipette it must be taken into account that it has three fundamental steps in general. As are rest or repose, the first stop and the second stop. Hence the following generalities for its use are derived. The range of the instrument must be chosen according to the liquid to be measured.
Adjust the increase or decrease of the absorbed solution, moving the knob to both sides. Select the sterilized end that will make contact with the liquid and place it in the appliance. The instrument should be kept with the narrow tip pointing towards a different place from the site to be inoculated.
Placing the thumb to press the button or plunger. Hold the clamped plunger immersed 1 mm inside the solution. Gradually releasing the plunger from the still function, which finishes entering the substance, remove the measuring object. Check the desired filling in the equipment correctly without any novelty.
Transfer the amount of liquid to the receiving container, the inclined micropipette should be placed. To dispense the substance I pressed the plunger towards the stop button. Then do it again strongly by activating the blow hole. Release the plunger, so that it returns to its initial position and use the release valve, detaching the suction end.
✨How many types of micropipettes are there?
Today there are various types of micropipettes that depend on the model made by the manufacturers among which it is. Automatic ones such as multichannel, repeater, electronic. Multichannel equipment, are those who perform the taking of several equal volumes at the same time.
They also suck and dispense several times. Electronic, they have history on their adjustable use, with intelligent applications. Manual, are those where the absorption is obtained by turning a button connected to the device system. Simple, they are the ones that only support tip each time it is used.
✨Parts of a micropipette
The laboratory micropipette is constituted with a push button or plunger, suction and liquid dispenser. The adjustment of the screw is carried out by moving the knob by placing the amount of liquid to be used in the system. Ejection button, consists of the automatic eviction of the disposable end of the device.
The finger grip, designed to provide comfort without tiring. Sure to change, it is a tab to activate or deactivate the setting the amount to be dispensed. The volume indicator is the screen where the amount to be used can be displayed. Indicator, the value at which you will be able to pipette.
The coupling cone, located at the narrow end, is where the disposable tips are placed. These are of different colors and diameters. The stem is a fixed cylinder, contained in the apparatus and can be inserted into narrow containers.
