Bottles are for general laboratory use, but are especially good for light-sensitive materials or photo- sensitive samples.

• Ideal for light-sensitive materials or photosensitive samples
• Leakproof
• Easy-to-pour wide mouth design

Can be stored in freezer to −100 °C (−148 °F), and have excellent chemical resistance to alcohols, akalis, and both diluted and concetrated acids. Thick walls afford durability. Shrink ring at neck ensures smooth interior so that contents pour fluidly, while sealing ring and semi-buttressed threads in closure ensure leak prevention. Bottles are produced via the injection blow molding process for exact features and bottle stability.
