Ungraduated glass aspirator bottles have a ground socket sidearm outlet located at the base of the bottle for attaching a compatible stopcock (available separately), and an open, ground socket neck.

• Made of high quality, heavy duty, borosilicate 3.3 glass
• Superior durability and chemical resistance
• Ground joints at outlet and neck for attaching stopcock or other compatible glassware (available separately)

Glass aspirator bottles are autoclavable, and offers superior chemical durability and a low temperature gradient. They can withstand high temperatures and thermal shocks.

Eisco borosilicate glass has the following heat tolerances: strain point of 515 °C, annealing point of 565 °C, and softening point of 820 °C.
