Analytical Graduated Pipette

Quick Answer

An analytical graduated pipette is a glass pipette marked with a full scale of graduation lines along its length, allowing a chemist or lab technician to measure and deliver a range of different liquid volumes from a single pipette rather than only one fixed amount.

Description

Unlike a single-mark volumetric pipette, a graduated pipette carries a full series of calibration lines down the barrel, so it can dispense any volume within its range rather than just one fixed amount. This flexibility makes it useful for day-to-day analytical work where the required volume changes from one step or one sample to the next, without needing to switch pipettes every time.

The pipette is made of glass and is designed to be used with a pipette filler or bulb, drawing liquid up past the required graduation and then dispensing down to the target line while reading the meniscus at eye level. Because the markings run the length of the barrel, technique and a steady hand matter more than with a volumetric pipette, and results are generally most consistent when the same technician reads and dispenses the same way each time.

Specifications

Applications

• Dispensing variable small volumes of reagent during titration or sample preparation
• Serial dilution work where each step needs a different measured volume
• General reagent transfer where the required amount changes from test to test
• Teaching labs demonstrating pipetting technique and volume reading

Care & Handling

• Always use a pipette filler or bulb; never draw liquid up by mouth
• Read the graduation mark at eye level, aligning the bottom of the meniscus with the target line
• Rinse and dry the pipette between different reagents to avoid cross-contamination
• Store in a pipette rack or stand rather than laid loose on the bench
• Handle by the upper stem and avoid touching the graduated section with wet or oily hands, which can obscure the markings

Frequently Asked Questions

What is the difference between a graduated pipette and a volumetric pipette?

A graduated pipette has a full scale of markings and can deliver any volume within its range, while a volumetric pipette has a single calibration mark and is built to deliver only one fixed, highly accurate volume.

What is an analytical graduated pipette used for?

It is used to measure and dispense variable volumes of liquid during titrations, dilutions, and general sample preparation, wherever the amount needed changes from one step to the next.

Can I measure different volumes with the same pipette?

Yes, that is the main advantage of a graduated pipette over a volumetric one; you can draw up to any graduation line and dispense down to any other line within its printed range.

Is a pipette filler required to use this pipette?

Yes, a pipette filler or bulb should always be used to draw liquid into the pipette rather than mouth pipetting, which is standard laboratory safety practice.

How should I read the graduation marks accurately?

View the pipette at eye level and align the bottom of the liquid’s meniscus with the graduation line you are measuring to or from, rather than reading at an angle, which can introduce error.

Can LabEquip supply graduated pipettes in bulk for a laboratory?

Yes, LabEquip supplies graduated pipettes in bulk for schools, colleges, and laboratories; contact us with your required quantity and capacity and we will assist with the order.
