Borosilicate Volumetric Pipette

Quick Answer

A borosilicate volumetric pipette is a single-mark glass pipette calibrated to deliver one precise, fixed volume of liquid, used wherever an analytical procedure calls for an exact quantity of solution rather than an adjustable or approximate volume.

Description

This single-mark volumetric pipette has a bulb-shaped body and a single calibration ring etched around a narrow stem, so the pipette holds and delivers one exact volume when filled to that ring and drained correctly. It is built from borosilicate glass, which resists most laboratory reagents and holds its calibration accurately over repeated use, making it the standard tool wherever a procedure specifies an exact volume rather than an approximate one.

Volumetric pipettes like this one are central to preparing standard solutions and to any quantitative technique where the starting volume has to be known precisely, since even a small error at this step carries through the rest of a calculation. They are always used together with a pipette filler or bulb rather than by mouth, both for safety and to keep the calibrated volume accurate.

Specifications

Applications

• Preparing standard solutions of a known, exact concentration
• Measuring precise aliquots for titration and other volumetric analysis
• Diluting stock solutions to an exact target volume
• General quantitative transfer of liquid reagents in a teaching or analytical laboratory

Care & Handling

• Always use a pipette filler or bulb; never fill by mouth
• Fill to the calibration mark with the meniscus read at eye level for an accurate volume
• Allow the pipette to drain naturally against the receiving vessel wall rather than forcing out the last drop, following the technique specified for the pipette
• Rinse thoroughly with distilled water after use and before switching to a different reagent
• Store upright in a pipette stand or rack to protect the tip from chipping

Frequently Asked Questions

What is a volumetric pipette used for?

A volumetric pipette is used to measure and deliver one precise, fixed volume of liquid, most often when preparing standard solutions or transferring an exact aliquot for a titration or other quantitative analysis.

Why is this pipette made from borosilicate glass?

Borosilicate glass resists attack from most laboratory acids, bases, and solvents and holds its shape and calibration reliably over years of use, which matters for a pipette whose whole purpose is delivering an exact, repeatable volume.

How accurate is a volumetric pipette compared to a graduated pipette?

A single-mark volumetric pipette is generally more accurate for its one specific volume than a graduated pipette measuring the same amount, because it is manufactured and calibrated specifically around that single fill line rather than a full length of graduation marks.

Can I fill this pipette by mouth?

No, a pipette filler or bulb should always be used instead of mouth pipetting, both as standard laboratory safety practice and because it gives more controlled, accurate filling and draining of the pipette.

How do I read the volume correctly on a volumetric pipette?

Hold the pipette vertically at eye level and fill until the bottom of the liquid meniscus sits exactly level with the calibration mark etched around the stem, then allow it to drain by gravity following the pipette’s intended technique.
