Aspirator Bottle (Clear Glass)

Quick Answer: The Aspirator Bottle (Clear Glass) is a transparent glass bottle with an outlet near the base for drawing off liquid. A clear glass aspirator bottle lets users see how much liquid is left and whether it is still clean, which opaque or amber bottles hide.

Why Clear Glass for a Reservoir

Stored liquids change over time, and in a transparent bottle those changes are visible. Distilled water left standing in light can develop a green film of algae or cloudy bacterial growth, solutions may form crystals or sediment, and a dispensing reservoir can run low without warning. With clear walls, the level, colour and clarity can be checked at a glance before any liquid is used.

Glass also resists most aqueous reagents and does not leach plasticisers, so it suits water for sensitive work such as staining, where residues could spoil results. The trade-off is light: clear glass protects nothing from it, so light-sensitive reagents belong in amber bottles, and water reservoirs should be kept away from windows to slow algal growth. The listing says ‘clear glass’ without stating whether it is borosilicate or soda-lime glass, which matters mainly for how the bottle tolerates hot liquids and repeated sterilisation.

Capacity and the outlet fitting are also not given. The general aspirator bottle page explains the respiration experiments these bottles are used for.

Keeping the Bottle Clear

• Empty, rinse and refill the clear glass aspirator bottle regularly rather than topping up old water.
• Place it away from windows and strong light to slow algal growth in stored water.
• Remove film or deposits with a bottle brush and a laboratory detergent, then rinse with distilled water.
• Check the glass for chips around the outlet before refilling.

Applications

• Reservoir of distilled water for rinsing slides and glassware
• Visible supply of saline or buffer for teaching practicals
• Demonstration set-ups where students must watch the water level fall, such as respiration or gas displacement experiments
• Short-term storage of prepared solutions that must be checked for sediment before use

Frequently Asked Questions

Why choose clear glass over amber or plastic for this bottle?

Clear glass shows the liquid level and any cloudiness, growth or sediment at a glance, and glass does not leach plasticisers. Choose amber only when the contents are sensitive to light.

Why does green growth appear in stored distilled water?

Light and a few airborne cells are enough for algae to grow slowly, even in distilled water. Keeping the bottle away from light and changing the water regularly prevents it.

Can hot liquids be poured into the bottle?

That depends on the glass. Borosilicate glass tolerates temperature changes much better than soda-lime glass, and the listing does not say which is used, so fill it only with liquids at room temperature unless the rating is known.

How do I clean deposits from the inside?

Use a long bottle brush with laboratory detergent, rinse several times with tap water and finish with distilled water. Mineral scale can be loosened with a dilute acid rinse followed by thorough rinsing.

Is it suitable for light-sensitive reagents?

No. Clear glass lets through the light that degrades reagents such as silver nitrate and some vitamin and dye solutions. Store those in amber bottles.

What size is the bottle?

Aspirator bottles are made in several capacities and the listing does not state this one, so confirm the size and outlet fitting when you enquire.
