Pipet Consciousness
Pipet is a laboratory tool used to take, move, or measure the volume of fluid with a certain level of precision. It's usually made of glass or plastic and available in different forms and sizes, depending on its function.
In the school lab, pipetes are often used during chemical, biological and pharmaceutical practices to measure small volume solution. Read it too "How much for a laboratory pet in Indonesia? Keep an eye on the price here“
Pipeting works by the principle of air pressure: liquid will enter or exit the pipe through a siphon or auxiliary tool aid such as filler pipes or micropipe plunger.
Pipette History
The modern pipeline was first introduced by Louis Pasteur In the 19th century. Initially, the pipeline was just a simple glass tube used to move liquid without measurement scale.
The development of laboratory technology then presents a pipeline of precision volume scale, to its creation. micropipe in the 1950s by Heinrich Schnitger, a German scientist.
Since then, pipeting has been one of the mandatory equipment in almost any kind of lab.
Pipette Function
The main function of the pipeline among others:
- Measure liquid volume Exactly.
- Move the liquid from one vessel to another.
- Retrieving samples for analysis or experiment.
- Add solution Gradually in the sequence process.
- Mixing a certain amount (especially on biotechnology and pharmaceutical research).
Type
Pipette has a variety of types that are used according to the need of practice:
1. Volume Pippette (Volumetric Pipette)
- It's a lean shape with a dilated center.
- Designed to measure one particular volume only (for example 10 mL).
- High precision, fit for standard solution.
2. Pépette
- It has size scales all over it.
- It can measure various volumes of liquid.
- Used when volume flexibility is required.
3. Pasteur Pills
- Made of glass or plastic without scale.
- Used for qualitative fluid move.
- Usually used together rubber balls as a suction.
Four. Micropipette
- A very small, modern pickpocket.
- Used in molecular biology labs and microbiology.
- Very precision, suitable for DNA research or enzyme.
5. Automatic Picket
- Using mechanical or electronic systems to suck and release fluids.
- Easily work with small volumes and lots of samples.
Right Pipette Tip
So that the results of the practice are accurate, following the follow-up tips:
- Use the fluid-type pipe and measured volume.
- Don't smoke liquid with mouth picking because it's dangerous.
- Clean before and after use.
- Hold the pipe upright when measuring the volume.
- Use a filler pad or a safety aids kit.
Conclusion
Pills are an important tool in the lab that functions to measure and move liquid with precision. The progress of simple pipes to modern micropipette shows how vital this device is to research and education.
For high school students, understanding the types and ways of properly using pistols will help in practice and grow basic laboratory workmanship.
