Additional Info:
58819-05 MICROSOLV Safety‑Coated Glass Bottle is a high‑quality Type‑33 borosilicate glass container designed for HPLC mobile phase reservoirs and broader laboratory solvent handling where safety, durability, and chemical purity are critical.
One of our most popular items, this bottle is widely used not only in chromatography labs but also across analytical, pharmaceutical, environmental, and general laboratory workflows due to its excellent glass quality and protective safety coating.
The internal surface is uncoated, chemically inert borosilicate glass, ensuring:
Low extractables and leachables
High solvent purity
Compatibility with aqueous and organic mobile phases
Safety‑Coated Design – Spill & Breakage Protection
The external transparent polymer coating is engineered to reduce hazards in the event of breakage:
Helps contain glass fragments and liquid if dropped
Reduces risk of cuts and solvent exposure
Prevents spill incidents and lab contamination
Maintains full visibility of contents
✅ Designed to help avoid safety “incidents” in busy laboratory environments
✅ Ideal for shared labs, high‑traffic areas, and solvent‑handling workflows
High‑Purity Borosilicate Glass – Analytical Performance
Constructed from Type‑33 borosilicate glass
Excellent chemical resistance and dimensional stability
Low leachables for sensitive analytical workflows
Maintains solvent integrity and reproducibility
✅ Delivers the same analytical performance as non‑coated glass bottles
2 L Format – Extended Workflow Capacity
2 L total fill capacity for longer run times
Clear glass with white enamel graduations
Easy solvent level monitoring to avoid running dry
Larger capacity reduces frequency of bottle changes
✅ Ideal for longer analytical runs and higher solvent consumption workflows
GL45 Thread – System Compatibility
Standard GL45 threaded neck
Includes solid screw cap (no liner) and polypropylene drip ring
Compatible with:
Solvent pickup filters
Degassing systems
Mobile phase delivery assemblies
✅ Integrates seamlessly with HPLC, UHPLC, and LC‑MS systems
