Borosilicate Specimen Jar

What is it?

A Borosilicate Glass Specimen Jar is a wide-mouth, thick-walled glass vessel designed for the safe, long-term storage and display of biological, pathological, and chemical specimens. Its straight-sided, optically clear body and airtight lid make it the preferred choice for museums, medical colleges, veterinary institutions, forensic laboratories, and natural history collections that need to preserve specimens in formalin, alcohol, or other fixative solutions for years without leakage, evaporation, or glass degradation.

Key Features and Benefits

• Premium Borosilicate 3.3 Glass: Engineered for excellent chemical resistance against formalin, ethanol, glycerin, and other preservative fluids, ensuring the fixative never clouds, discolors, or reacts with the glass over years of storage
  
• Wide-Mouth Design: The generous opening allows specimens of varying shapes and sizes to be inserted, positioned, or removed easily without damage.
  
• Airtight Ground Glass / Screw Cap Lid: Available with a precision-ground interchangeable glass lid or a leak-proof Bakelite/PP screw cap, both designed to prevent evaporation and keep preservative levels stable for years.
  
• Optical Clarity for Display: High-transparency glass ensures specimens remain clearly visible for study, teaching, or museum exhibition without distortion.
  
• Heavy, Stable Base: A wide, flat, reinforced base and uniform wall thickness provide excellent stability on shelves and resistance to accidental tipping or impact.
  
• Stress-Free Annealed Glass: Every jar is annealed to remove internal glass stress, giving it long-term structural reliability even when stored for decades.
