Pyrex Glass Food Storage Containers vs. Nalgene Tritan Wide-Mouth Bottle

Materials

• Tempered soda-lime glass
• Plastic or silicone lids

Common claims

• Oven, microwave, and dishwasher safe
• BPA-free lids
• Non-porous glass

Concerns / watch-outs

• Modern Pyrex sold in the US uses tempered soda-lime glass, not borosilicate — more susceptible to thermal shock than older versions
• Plastic lids may contain BPA; look for confirmed BPA-free lids or use silicone alternatives

Notes

Pyrex glass is one of the most recommended non-toxic food storage options. The glass body is completely inert. Replace plastic lids if they become scratched or stained.

Cleaner alternatives

• borosilicate glass container
• mason jar

Materials

• Eastman Tritan copolyester
• BPA-free

Common claims

• BPA-free
• Virtually unbreakable
• Made in USA

Concerns / watch-outs

• Tritan plastic can leach tritan-specific chemicals (EA and YY) under stress
• Not stainless or glass — still a plastic bottle
• Long-term safety data on Tritan monomers is still evolving

Notes

Best of the plastic bottle category, but still plastic. Fine for occasional use. For daily carry, stainless or glass is preferable.

Cleaner alternatives

• klean kanteen bottle
• hydro flask bottle
