Wash Bottles

Wash bottles are a practical and frequently used piece of laboratory equipment, used to dispense solvents, water, and reagents in a controlled manner for rinsing glassware, washing precipitates, and delivering small quantities of liquid during laboratory procedures.

At Hurst Scientific, we supply laboratory wash bottles to research facilities, schools, universities, and commercial laboratories across Australia.

Types of Wash Bottles

Polyethylene (PE) Wash Bottles are the most common type in general laboratory use. Lightweight, squeezable, and chemically resistant to a wide range of aqueous solutions, they are suitable for dispensing distilled water, ethanol, and many common laboratory reagents.

Wide-Mouth Wash Bottles allow easier filling and cleaning, and are particularly useful when working with solutions that tend to foam or crystallise around the nozzle.

Common Uses for Wash Bottles

• Rinsing glassware with distilled or deionised water
• Washing precipitates on filter paper during gravimetric analysis
• Delivering small volumes of solvent or reagent dropwise
• Rinsing electrodes and probes before measurement
• General bench use in teaching and research laboratories
• Dispensing ethanol, acetone, or other cleaning solvents

Frequently Asked Questions

What volume wash bottles should I use? The most common sizes for laboratory use are 250ml, 500ml, and 1000ml. Smaller bottles are suited to bench use where precise rinsing is needed; larger bottles are more practical for high-volume washing tasks.

Are wash bottles chemically resistant? Standard polyethylene wash bottles offer good resistance to most aqueous reagents, alcohols, and dilute acids and bases. For use with strong solvents such as acetone, toluene, or chlorinated solvents, always check compatibility before use as prolonged exposure can degrade standard PE.

Should wash bottles be labelled? Yes. Always label wash bottles clearly with the contents, concentration, and any relevant hazard information. Never use unlabelled wash bottles in a laboratory environment.

Can I order wash bottles in bulk? Yes. Hurst Scientific supplies wash bottles in bulk quantities. Contact us for volume pricing.
