This guide explains the practical difference between a burette and a pipette, two instruments that are often confused because both dispense measured volumes of liquid, but that are built for genuinely different jobs. It breaks down how a burette's stopcock and full-length graduated scale let an operator dispense a variable, watched volume and stop the instant a reaction reaches its endpoint, versus how a pipette (volumetric, graduated or micropipette) is built to transfer one known or pre-set volume in a single action. Rather than presenting the two as competing options, the piece frames them as complementary tools tied to different steps in a procedure: burettes for titration and any reaction where the target volume isn't known in advance, pipettes for sample preparation, dilutions and any step where the volume is already fixed.

This guide compares the five graduated cylinder brands most commonly used across Australian laboratories: Hirschmann Laborgeräte (DURAN® glass), Kartell (PMP plastic), ISOLAB Laborgeräte, BRAND (BLAUBRAND®) and VITLAB. Rather than treating graduated cylinders as interchangeable, it breaks down what actually separates them, Class A versus Class B accuracy tolerances, glass versus plastic construction, base stability and certification standards such as USP conformity, and explains which of these differences genuinely matter depending on the work.

This guide compares the five Erlenmeyer flask brands most commonly used across Australian laboratories today: DWK Life Sciences (DURAN®), ISOLAB Laborgeräte, LLG Labware, BRAND and Kartell. Rather than treating all Erlenmeyer flasks as interchangeable, it breaks down what actually separates them in practice, wall thickness consistency, thermal shock resistance, neck and closure compatibility, and material choice between borosilicate glass and polypropylene, and explains which of these differences matter for which kind of lab work.

A Bunsen burner mixes fuel gas with air to give an adjustable flame for heating, flame tests and sterilisation. This guide explains how they work, compares standard, Tirrill, Teclu, Meker, safety and micro burners, and helps you match a burner to your gas supply and application.

Laboratories can present a wide range of fire hazards, including flammable solvents, electrical equipment, combustible materials, reactive metals and lithium-ion batteries. This guide explains Australian fire classes, compares the main types of laboratory fire extinguishers and outlines how to select suitable protection based on the chemicals, equipment and processes within your laboratory.

A laboratory mortar and pestle crushes, grinds and homogenises small solid samples before analysis. This guide explains how they work, compares porcelain, agate, glass, stainless steel and alumina, and helps you choose the right set for your application without contaminating the result.

Learn what borosilicate glass is, how Boro 3.3 is made and why its low thermal expansion, chemical resistance and optical clarity make it suitable for Australian research, mining, environmental, food, education and industrial laboratories.

A laboratory desiccator is a sealed vessel that keeps its contents in a dry, low-humidity atmosphere, protecting moisture-sensitive samples and reagents and cooling heated samples without reabsorbing water. This guide covers what it is, what it is used for, the main types, the desiccants that go inside, and how it works, with an animated drying cycle and a setup finder built in.

The Buchner funnel is the standard tool for fast vacuum filtration, separating a solid from a liquid far quicker than gravity. This guide covers what it is, what it is used for, how to set one up step by step, the main materials, and how vacuum filtration works, with an animated apparatus and a funnel finder built in.

Cleaning laboratory glassware properly is essential for accurate, safe, and repeatable lab work. This guide explains how to remove stubborn residue from beakers, flasks, bottles, volumetric glassware, and other lab glassware, including grease, dried salts, biological residue, stains, and burnt deposits. It also covers safe cleaning methods, common mistakes, drying and storage tips, and when damaged glassware should be replaced.

Pipette calibration helps laboratories confirm that liquid handling results remain accurate, repeatable, and traceable. This guide explains how pipettes are calibrated to ISO 8655 standards, including gravimetric testing, environmental control, correct tip selection, volume testing, calibration records, and common mistakes to avoid. It also covers when to use in-house calibration and when an external calibration service may be more suitable.
