20ML Glass Sample Vials 100 Pack - Leakproof Clear Borosilicate Vials

In this review the ESHATO 100 Pack 20ML Glass Sample Vial set is evaluated for lab hobbyists and small-batch makers who need compact, reusable containers. The bottom line: these clear borosilicate vials deliver durable, lightweight storage with reliable screw caps, making them a smart choice for essential oils, small liquid reagents, glitter, seeds, and other samples where corrosion resistance and visibility matter. The review focuses on build quality, leak protection, and everyday usefulness rather than advanced laboratory certification.

Key Features

• Premium glass: Made from borosilicate glass so the vials resist thermal shock and chemical corrosion for repeated use.
• 20ml capacity: Each vial holds 0.34 fl oz in a compact 27.5 x 57 mm form factor that is easy to store and transport.
• Leakproof screw caps: Black polypropylene caps with a PE liner and gasket create a tight seal to minimize spills during handling.
• Clear visibility: Transparent construction makes it simple to identify contents at a glance without opening the vial.
• Versatile storage: Suitable for liquids, powders, seeds, specimens, essential oils, perfumes and small pharmaceutical samples.
• Safe packaging: Ship-ready boxes protect the vials in transit so most customers receive them intact and ready to use.

Who It's For

These vials are ideal for hobbyists, craft makers, and small labs that need an affordable supply of uniform, reusable sample bottles. People storing essential oils, perfume samples, reagents for small experiments, or craft materials like glitter will appreciate the clear borosilicate construction and compact size.

Those who require certified laboratory sampling equipment with documented sterility or traceable calibration should look elsewhere; this pack is designed for general-purpose storage and everyday use rather than regulated clinical applications.

Pros & Cons

Pros

• Durable borosilicate glass construction resists temperature variation and corrosion.
• Compact 20ml size is convenient for storage and small sample needs.
• Screw caps with PE liner provide a strong seal that prevents most leaks when closed properly.
