Product Description

Specimen Jars are specialized containers for biological specimen display and preservation in laboratories, manufactured from borosilicate glass 3.3. Featuring high clarity for easy observation of specimen details, they are widely used in biology teaching, research display, and museum exhibitions.

Key Features

Borosilicate glass 3.3: ISO 3585 compliant, thermal shock resistant to 280°C, excellent chemical resistance
High clarity: Pure, transparent glass allows easy observation of specimen details
Multiple sizes: Available in a wide range of sizes for different specimen display needs
Excellent sealing: Ground glass stopper provides secure protection for specimens
Chemical stability: Resistant to most preservation solutions

Quality Assurance

Every unit undergoes rigorous dimensional inspection, seal integrity testing, and visual examination to meet the high standards required in professional laboratories.

Note: Specimen Jars are designed for biological specimen display and preservation. Ensure the jar is clean and dry before use. Preservation solution should completely cover the specimen. Regular seal integrity checks are recommended for long‑term preservation.

Applications

Typical Uses

Biology teaching

Display and observation of plant and animal specimens

Research labs

Preservation and morphological study of biological samples

Museum exhibitions

Long‑term display of biological specimens

Medical teaching

Preservation and display of tissue specimens

Agricultural research

Tip: Specimen Jars work together with reagent bottles, weighing bottles, and other lab containers to cover a wide range of sample storage, display, and weighing applications.

Operation & Maintenance

Specimen Jar User Guide

Before Use

Inspect for cracks, chips, or scratches before use
Ensure the jar is clean and dry to prevent contamination of specimens
Verify that the stopper fits properly — no wobble or sticking

Specimen Preservation Procedure

Place the specimen into the jar and slowly add preservation solution (e.g., formalin, alcohol)
Ensure the preservation solution completely covers the specimen
Seal with the stopper — ensure a tight seal
Wipe the exterior clean and apply a specimen label (name, date, preservation solution, etc.)
Store in a cool, dry, dark location

Cleaning & Maintenance

Clean promptly after use to prevent residue from hardening
Wash with detergent and a soft brush, rinse 3× with distilled water
For stubborn residues, soak in dilute acid or specialty cleaning solution
Allow to air‑dry inverted on a draining rack
For long‑term storage, place a small piece of paper between the stopper and the neck to prevent seizing
