Catalog Number - 58819-05R

58819-05R 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.

This configuration features an open red screw cap and polypropylene pouring ring, providing improved access and controlled solvent handling for workflows requiring frequent transfer or tubing access.

These bottles are widely used not only in chromatography laboratories, but also across analytical, pharmaceutical, environmental, and general laboratory workflows due to their 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

• Clear glass with white enamel graduations

• Easy solvent level monitoring to prevent running dry

• Larger capacity supports longer runs and reduces bottle changes

✅ Ideal for high‑throughput and extended HPLC / LC‑MS workflows
