Glass Pipettes

Glass pipettes are for work where the volume has to be right. A volumetric pipette has a single mark and delivers one fixed volume, which is why it's the standard tool for titrations. Graduated and serological pipettes are marked along the tube, so you can measure off any volume up to their capacity.

Class A volumetric pipettes, from 1ml to 100ml, have the tightest tolerance and suit analytical and university work. Class B costs less and is accurate enough for most school practicals. We carry Class B volumetric pipettes up to 100ml, graduated pipettes from 1ml to 50ml and serological pipettes from 0.1ml to 25ml, including OMSONS and JOANLAB borosilicate glass.

If the exact amount doesn't matter, the soda glass Pasteur pipettes (boxes of 200 or 250) and the 125mm glass dropping pipette with a rubber teat are cheaper. Never pipette by mouth: fit a pipette filler bulb or a pipette pump first.

Orders go out from our Boksburg warehouse to schools and labs anywhere in South Africa.

What is a laboratory glass pipette?

Laboratory glass pipettes are precision-calibrated glass tubes designed to transfer accurate volumes of liquid in analytical and preparative work. The main types are graduated (Mohr) pipettes with a continuous scale for flexible volume delivery; volumetric (bulb) pipettes with a single calibration mark for one precise fixed volume; Pasteur pipettes for dropwise transfer; and burettes for variable volume dispensing during titration. All SmartLabs glass pipettes are manufactured from borosilicate glass 3.3.

Common uses of laboratory glass pipettes in the lab

From dropwise transfer with a Pasteur pipette to precise burette dispensing in titration, glass pipettes are the standard tool for accurate liquid handling across chemistry, biology, and analytical science.

  • An analyst filling a pipette with a bulb over conical flasks

    Volumetric titration

    Graduated and volumetric pipettes transfer precise volumes of titrant or sample. Volumetric pipettes deliver a single fixed volume with high accuracy and are the reference instrument for preparing standard solutions and performing quantitative analysis.

  • A gloved hand using a Pasteur pipette over a rack of sample vials

    Dropwise transfer

    Pasteur pipettes are thin-stem glass transfer pipettes fitted with a rubber bulb, used to add reagents dropwise, transfer small volumes, and remove supernatant from centrifuged samples in biology, histology, and chemistry work.

  • A burette clamped on a stand above beakers and reagent bottles

    Burette dispensing

    Burettes are long, precisely graduated glass tubes with a stopcock, used to dispense variable volumes of titrant with high accuracy during acid-base, redox, and complexometric titrations. The stopcock allows precise control at the endpoint.

    Precise volume delivery

    Volumetric pipettes have a blown-glass bulb and a single calibration mark, calibrated to deliver a precise fixed volume. They are the highest-accuracy pipette type, used for standard solution preparation, method calibration, and certified reference material work.
