Aspirator Bottles

Aspirator Bottles are specially designed borosilicate glass bottles equipped with a side outlet or stopcock, enabling controlled liquid dispensing, vacuum aspiration, and filtration operations in laboratory environments.

At Bhanu Scientific Glass Co., aspirator bottles are manufactured using borosilicate glass 3.3, ensuring high chemical resistance, thermal stability, and excellent transparency. These bottles are widely used for vacuum filtration setups, waste liquid collection, and safe reagent handling, especially where gravity-assisted or vacuum-driven discharge is required.

Available in capacities up to 20 liters, aspirator bottles can be supplied as standard storage bottles, media bottles, or aspirator variants with outlet nozzles, making them versatile for research, analytical, and industrial laboratories.

How an Aspirator Bottle Works

1. Liquid is filled into the aspirator bottle through the top opening
2. The bottle is sealed using a stopper or cap
3. A hose is connected to the side outlet / stopcock
4. Liquid is discharged either by gravity flow or vacuum assistance
5. Flow rate is controlled using a valve or stopcock

This design allows safe, spill-free transfer and collection of liquids, particularly in vacuum filtration or waste handling systems.
