Nalgene™ PETG Ultra-Low Particulate Media Bottles - FAQs

What is the difference between the following Nalgene Square PETG Media Bottles: Cat. No. 2019-xxxx (with Closure), Cat. No. 342020-xxxx (with Closure: Sterile, Shrink-Wrapped Trays), Cat. No. CE-N2019-xxxx (Platinum Certified Clean)?

All three products use the same PETG bottles, so the materials and specifications are the same for the bottle itself. Cat. No. 342020-xxxx is supplied with natural-colored HDPE closures, while Cat. No. 2019-xxxx and Cat. No. CE-N2019-xxxx are supplied with white HDPE closures. The HDPE resin used for the closures is the same, but a white colorant has been added to the resin for Cat. No. 2019-xxxx and Cat. No. CE-N2019-xxxx (this will be noted on the COA). Cat. No. 2019-xxxx also has a PVC tamper-resistant seal around the closure, while Cat. No. 342020-xxxx does not.
