Common Uses and Applications
- Safe Chemical Dispensing: Perfect for sitting on a shelf and dispensing acids or solvents into smaller containers without lifting a heavy bottle.
- Distilled Water Storage: Used frequently as a reservoir for distilled or deionized water, allowing you to fill beakers easily from the bottom tap.
- Waste Collection: Ideal for collecting liquid waste in a vacuum setup, where the GL45 cap keeps the air out and the stopcock lets you drain it safely.
- Bulk Mixing: Great for preparing large batches of buffer solutions or culture media, as the Boro 3.3 glass can handle the heat of sterilization.
