The roots of the automated laboratoryliquid handlingcan be traced back to the increasing focus on analytical laboratory techniques in the late 18th century. Descroizilles, a French chemist and pharmacist, invented and first introduced the buret and pipet to science in 1795. He called his burette a "
berrholli-metere": it was a graduated cylinder. He later described an "alcalimetre," to dispense small volumes of liquids. Not until 1824 did
Gay-Lussac publishthe names "burette" and "pipette" (French, "wine tester"; Ferenc Szabadvdry, Instruments).A major breakthrough in the methodology and popularization of volumetric analysis was achieved by
Karl Friedrich Mohr, who redesigned the burette by placing a clamp and a tip at the bottom. The syringe, on the other hand, was not graduated in its early stages. Early syringes were often made of metal rather than glass to avoid breakage when transported in saddlebags. A patent by Martin Overlach, "resident at Frankfort-on-the-Main, Germany" (U.S. Patent 404105, 1889), recognized a need for a syringe to house a chamber that didn't leak. Because of their mechanical nature, the syringe provided a "modernizing 'professionalization' tool," wielded by 19th-century doctors.

What is the most precise means of measuring liquid volume?
A micropipette or burette can be used to manually measure quite accurately. Pumps can be used in automated instruments. It has to be noted that the lower the volume the less accuracy and precision can be obtained.
Can the NaOH solution be blown out of the pipette to reduce the time for the transfer?
It is not recommended to blown up solutions from the pipettes. Volumetric pipettes are not blow-up.
Why do you use pipettes for titrations?
to measure and transfer liquids accurately
Why is a volumetric pipette more accurate than a graduated pipette?
Graduated pipettes are not as accurate as volumetric pipettes, because each graduation line is not individually calibrated, and any imperfection in the internal diameter will have a greater effect on the volume delivered. In volumetric pipettes, the diameter of the pipette where the graduation mark is located is significantly smaller because the majority of its volume is located in the bulb.
What are the equipment used for measuring volume?
Examples: graduated cylinders, graduated pipettes, biurettes, fluid counters etc.
Are micropipettes mechanical or biological vectors?
Micro-pipettes can be mechanical vectors for disease. Since they do not carry the disease like a living organism, they cannot be considered to be a biological vector. If the pipette is not sterilized properly, the result can be a mechanical vector for a disease.

What precaution should take during gel electrophoresis?
when using the micropipettes,be careful and avoid contaiinating the micropipettes by slowly releasing the plunger
When was We Are The Pipettes created?
We Are The Pipettes was created in 2006.
When was The Pipettes created?

Mohr pipettes the same as graduated pipettes?
For the use they are similar; differences are:- volumetric pipettes are more precise- the design is different
What are berol pipettes?
Berol pipettes are types of simple pipettes used in laboratories. They are disposable and have bulbous ends on them so that they can be used for suction.
Why is it important to handle micropipettes carefully?
It cost is very expensive
