Frequently Asked Questions
1. What is the difference between LDPE and HDPE bottles from Edwin Mraz?
LDPE (Low-Density Polyethylene) is more flexible and ideal for squeeze bottles and spray tubes, while HDPE (High-Density Polyethylene) is more rigid and offers slightly better chemical resistance for long-term storage.
2. Are Edwin Mraz plastic stoppers a good alternative to glass?
Yes. Edwin Mraz PE stoppers are unbreakable, lightweight, and provide an excellent airtight seal for ground joint glassware, reducing the risk of joint "freezing" that often occurs with glass-on-glass seals.
3. Can Edwin Mraz polypropylene (PP) bottles be autoclaved?
Yes, Edwin Mraz bottles made from Polypropylene are generally autoclavable at 121°C. However, LDPE and HDPE components should typically not be autoclaved as they may deform under high heat.
4. Do Edwin Mraz wash bottles come with pre-printed labels?
Edwin Mraz provides both plain bottles for custom labeling and specialized caps with spray tubes that can be fitted to various bottle sizes, allowing for a highly customizable dispensing system.
