6pcs 500ml Thick Glass Beakers Set - Durable Lab Griffin Low Form

In this review of the 6pcs 500ml Thick Glass Beakers Set the bottom line is simple: this kit is best for hobbyists, educators, and small labs that need clear, graduated glassware that holds up to routine use. The reviewer found the largest selling point to be the use of 3.3 borosilicate glass with uniform wall thickness and a printed double scale, which together deliver readable measurements and thermal stability for everyday mixing, heating and measuring tasks.

Key Features

• 500ml volume: Each beaker holds 500ml (about 17oz), offering a useful mid-size capacity for common lab and workshop tasks.
• 3.3 borosilicate glass: The material provides better thermal and chemical resistance than ordinary glass, reducing sudden breakage in normal use.
• Uniform wall thickness: Consistent walls improve handling balance and make stacking and cleaning more predictable.
• Double printed scale: Graduations are printed clearly on a low form beaker for easier reading and more reliable measuring.
• Extra large marking spot: A wide marking area allows quick labeling with a grease pencil or marker for sample identification.
• ASTM compliant: These beakers meet ASTM Specification E960 Type I requirements and carry a tolerance of approximately +/- 5% for volume.

Who It's For

This set is well suited to students, hobby chemists, small teaching labs, and craft users who need a matched group of mid-size beakers for mixing, measuring, heating and general glassware work. The clear graduations and marking spot make it practical for repeated experiments and multi-sample workflows.

Those who require precision volumetric measurement for critical analytical work or high-impact industrial glassware may want to look elsewhere; the stated tolerance of approximately +/- 5% and mixed reports on breakage suggest these are optimized for general-purpose use rather than precision metrology or heavy-duty industrial handling.

Pros & Cons

Pros

• Clear, double printed graduation makes readings quick and reliable for routine tasks.
• 3.3 borosilicate construction and uniform wall thickness provide improved thermal and chemical resistance over soda-lime glass.
• Extra large marking spot and matched set of six make organization and repeated procedures easier.
• Meets ASTM E960 Type I requirements, which is reassuring for laboratory compatibility.

Cons

• Tolerance of approximately +/- 5% limits use for high-precision volumetric work.
• Durability feedback is mixed; some users report breakage under routine use, so careful handling is advisable.

Frequently Asked Questions

Are these beakers heat resistant?
Yes, the 3.3 borosilicate glass provides improved thermal resistance compared with ordinary glass and is suitable for common heating and cooling cycles used in labs.

How accurate are the volume markings?
Markings use a double printed scale with an approximate tolerance of +/- 5%, suitable for general measuring but not for precision volumetry.

Do these come as a matched set?
Yes, the product is sold as a set of six identical 500ml Griffin low form beakers with uniform wall thickness and matching graduations.
