20ml pipette

Types of 20ml pipette

20 ml pipettes are important instruments used in laboratories to measure liquids. They come in different types to help with various tasks. Each type has special features that make it good for precise liquid measurements. Using the right kind of pipette makes sure the results of liquid measurements in a lab are accurate and dependable. Listed below are some of the common types:

Graduated Pipette

A graduated pipette has marks on it that show different measurement levels. These marks help the user choose the exact liquid amount needed. It is often used when the precise liquid volume needs to be measured, but not always exactly. For example, it can be used in chemical mixing or liquid transferring tasks where a rough volume measure is okay. This pipette is good at giving clean measurements but needs careful eye-level checking of the liquid meniscus to get the right measurement mark.

Volumetric Pipette

A volumetric pipette is designed to measure a specific volume of liquid very precisely. It has one wide section with a narrow neck to help give exact liquid amounts. This pipette is often the right choice for lab tests where precise amounts are vital. For example, in pharmaceutical experiments, even small measurement errors can change the results. The drawback is that it can only measure this one set volume. For varying liquid amounts, another type of pipette should be used.

Serological Pipette

A serological pipette is used to measure fluids in biological labs. Fluids to be measured include cell cultures and other biological samples. It has graduation marks all the way to the tip for accurate fluid removal. This helps users take out precise amounts of liquid without leaving residue. This pipette comes in different sizes, commonly 5 ml, 10 ml, and 25 ml, but often a 20 ml pipette is used.

Micropipette

A micropipette is used to measure very small fluid amounts, usually in microliters. It has one adjustable section that lets the user pick the exact small amount to test. Micropipettes are used a lot in genetics, making clones, and other tests where tiny fluid amounts are needed. Often, a small pipette tip is used to hold the precise liquid measured by the pipette. This makes cleanup simple between tests.

• Overall Length:Length of 200 mm to reach most fluid containers easily.
• Inner Diameter: 1 mm for even fluid flow in and out.

How to Install

• It is advised that users wash and dry the pipette before installation. Washing and drying help stop any old fluid from mixing with new ones.
• The first step is to attach the pipette tip to the pipette. The pipette should be turned on and then the pipette tip placed in the hole at the end of the pipette.
• Users slide the pipette tip onto the end to make sure it fits well. They must check that the tip is tightly stuck on. Users should not be able to pull the tip off easily.
• Next, the pipette is set to the right amount. The dial or push button is turned or pressed until it shows 20 mL.

How to Use

• The pipette tip is placed into the fluid to get the fluid. The tip is deepened by a few centimeters to avoid air from getting inside.
• The push button is pressed slowly until feeling resistance. This pushes out any air bubbles from the tip.
• The push button is pressed all the way down while the tip is in the fluid. This allows fluid to fill the tip.
• The button is released slowly. This helps the fluid rise into the tip.
• Users then carefully take out the pipette from the fluid. Make sure no fluid drips from the tip during this step.
• The push button is pressed slowly. This lets out any air bubbles to make sure the fluid amount is right.
• The measurement line on the pipette is checked. The fluid level needs to line up with this line.
• The push button is then pressed slowly again to release the fluid. This lets out the fluid comes from the tip.

Maintenance and Repair

• Pipettes need to be cleaned often. This makes sure new fluid does not mix with old fluid. Cleaning helps the pipette work better for a long time.
• Each part of the pipette must be checked often. Users look at the pipette to see if anything is broken or worn out. If parts work while damaged, mistakes happen.
• People are advised to wash pipettes with a soft cloth. Strong tools may harm the plastic or glass parts.
• Pipettes may sometimes need new parts. If parts have worn down, they should be replaced. Only real maker parts should be used to fix the pipette properly. This helps it work like new again.
• To avoid liquid leakage, users should always check that the pipette tip is tightly attached to the pipette before use.

Quality Check Criteria of 20ml pipette

Accuracy Testing

To check how correct a pipette is, labs use fluid moves and measuring tools. They compare what's moved with what should be moved. If it's close, the pipette is good.

Calibration Verification

Pipettes get checked to see if their marks on the tube match real measures. Tools check each mark to make sure the pipette's measures are right.

Leak Testing

Pipettes get fluid and pressure tested to see if any leaks happen. If fluid stays in the tip, it works well. Leaks mess up tests, so this step is key.

Wear Inspection

Checks look for wear on parts from use. Regular checks catch worn tips before they hurt accuracy. Tired parts get replaced to keep the pipette working well.

Environmental Testing

This examines how pipettes do in heat, cold, and other lab situations. It ensures they measure fluids the same in all lab spots.

Maintenance Review

Good use guides help users care for pipettes right. People do routine checks to keep them in good shape. Reviews check if the maintenance system keeps them working well.
