Jar: FAQ

How do I ensure the jar volume is accurate for my experiments?

Always verify the capacity in milliliters (ml) rather than just looking at the photo. Check the product description for 'graduated' markings to ensure the jar provides measurable volume increments.

How can I tell if the glass is genuine borosilicate?

Look for 'Borosilicate 3.3' in the specifications, which indicates high thermal shock resistance. High-quality lab jars will specify a temperature range they can withstand, usually up to 500°C.

What indicates a high-quality airtight seal?

Check for caps featuring PTFE or silicone liners, as these provide superior chemical resistance and prevent leaks. Ground glass stoppers are also a premium indicator for volatile chemical storage.

Will these fragile items arrive intact during international shipping?

Prioritize sellers who mention 'Double Layer Corrugated Box' or 'EPE Foam' packaging in their reviews. Many top-rated lab suppliers on AliExpress specialize in fragile logistics and offer breakage guarantees.

Recommendations for buyers

✓
Material Compatibility
Choose Borosilicate 3.3 glass for heat applications and Amber glass for light-sensitive reagents to prevent degradation.
✓
Neck and Opening Diameter
Select Wide Mouth jars for easy filling and cleaning of solids, or Narrow Mouth jars for precise pouring of liquid chemicals.
✓
Closure Standards
Look for GL45 or GL32 thread standards to ensure compatibility with universal lab equipment and automated dispensers.
✓
Graduation Permanence
Ensure the jar features fired-on ceramic graduations which are resistant to chemical erosion and repeated autoclaving.
