Frequently Asked Questions
1. Can Rettberg glassware be used in high-pressure applications?
Standard laboratory glassware is designed primarily for vacuum or atmospheric pressure. For applications involving positive pressure, Rettberg offers specialized thick-walled vessels and plastic-coated (PROTECT) safety glassware.
2. Is Rettberg glassware compatible with other brands?
Yes, Rettberg strictly follows international DIN and ISO standards for ground glass joints (e.g., NS 29/32), ensuring their components are fully interchangeable with other standardized laboratory brands.
3. What is the advantage of Rettberg's "PROTECT" coating?
The PROTECT coating is a highly transparent plastic sheath that provides scratch protection and, in the event of glass breakage, helps contain the glass splinters and the liquid contents, significantly increasing laboratory safety.
4. How should I clean specialized Rettberg reaction vessels?
Glassware should be cleaned with mild laboratory detergents. For stubborn residues, specialized glass cleaning baths can be used. Always ensure the vessel is stress-free and cool before applying sudden changes in water temperature.
