What the AI looks for in Lab Carboys
- Resin
- HDPE or LDPE for water and dilute reagents; PP if autoclaving; fluoropolymer for aggressive chemicals Only PP and fluoropolymers survive the autoclave, and polyethylene resists most aqueous chemicals.
- Spigot
- Built-in or replaceable spigot positioned near the base Spigots let you dispense without tipping a heavy vessel, which is safer and keeps the contents cleaner.
- Venting
- Vented cap when dispensing from a spigot Without venting, flow stalls and the walls can panel.
- Opacity
- Translucent for level checks; amber or opaque for light-sensitive contents Algae grow in water stored in light, and some reagents degrade in light.
Brands that matter
- Thermo Scientific Nalgene: Widest range of carboy resins and styles.
- Bel-Art: Budget carboys and spigots.
- DWK: Glass bottles in large sizes for solvents.
What to avoid
- Food or homebrew PET carboys for lab reagents
- Autoclaving polyethylene carboys
- Storing flammable solvents in plastic carboys outside a safety cabinet
