Glass filling bells are ideal for aseptical filling of vessels.

• Made of Pyrex® borosilicate glass

Rubber tubing is attached to the top of the tubulation while the receiving vessel is placed inside the bell. They can also be used with aspirator bottles that have a bottom sidearm tubulation to aseptically dispense sterile media and solutions. Filling bells with luer fitting can be used to fill very small-necked flasks using syringe needles or cannulas.
