Corning Pyrex 1000ml Narrow Mouth Erlenmeyer Flask #4980-1L with Rubber Stopper - Heavy Duty Lab Glassware

This Corning Pyrex 1L narrow mouth Erlenmeyer flask offers heavy-duty rims and uniform wall thickness for exceptional mechanical strength and thermal shock resistance. Lab technicians, educators, and researchers should buy it for reliable, precise volume measurements with included rubber stopper.

  • Heavy-duty rims minimize chipping for long-lasting lab use
  • Uniform wall thickness balances strength and thermal shock resistance
  • Clear graduations from 250ml to 1000ml enable precise measurements
  • Included rubber stopper ensures secure, contamination-free sealing
  • Compact 129 x 216mm size fits easily on crowded lab benches

Superior durability reduces breakage risk. Excellent thermal performance for heating applications. Accurate graduations simplify volume tracking.

Glass construction requires careful handling to avoid breakage. Narrow mouth limits access for large stirrers. Single flask per package, not ideal for bulk needs.

Corning Pyrex 500mL Erlenmeyer Flask #4980-500 with #7 Rubber Stopper - Heavy Duty Narrow Mouth Lab Glassware

This Corning Pyrex #4980-500 is a 500ml narrow-mouth Erlenmeyer flask with included #7 rubber stopper, featuring heavy-duty rims and uniform wall thickness for excellent mechanical strength and thermal shock resistance. Lab technicians, chemists, and students should buy it for reliable, graduated mixing and storage.

  • Heavy-duty rims prevent chipping for years of reliable lab use
  • Uniform wall thickness delivers optimal strength and thermal shock resistance
  • Durable white enamel graduations ensure precise 50-500ml measurements
  • Extra-large marking space simplifies labeling and organization
  • Includes #7 rubber stopper for secure, airtight sealing

Superior Pyrex glass durability against daily wear. Accurate, easy-to-read graduations in white enamel. Perfect-fit rubber stopper included for immediate use.

Glass requires careful handling to prevent breakage. Narrow mouth can slow pouring of viscous liquids. Single flask limits bulk purchasing value.

Welcome to our curated selection of Corning Chemistry Flasks, featuring two standout Pyrex Erlenmeyer flasks designed for precision and durability in laboratory settings. These 500ml and 1000ml models, each equipped with a rubber stopper, embody Corning's legacy of innovation in borosilicate glassware, making them essential for chemists, researchers, and educators seeking reliable tools for mixing, heating, and storing solutions.

Why Choose Corning for Your Chemistry Flasks?

Corning has built a reputation over decades as a leader in scientific glassware, particularly through its Pyrex brand, known for exceptional thermal shock resistance and chemical durability. Unlike generic options, Corning flasks are crafted from low-expansion Type 1 borosilicate glass, ensuring they withstand repeated sterilization and extreme temperature changes without cracking. This makes them a top choice for demanding environments like research labs, pharmaceutical testing, and academic institutions. As part of the broader Lab Flasks category, Corning products stand out for their precision-engineered necks and heavy-duty construction, reducing contamination risks and enhancing workflow efficiency.

Key Features to Look for in Corning Chemistry Flasks

When selecting a flask from this category, prioritize these Corning-specific attributes:

  • Material Excellence: Pyrex borosilicate glass offers superior clarity for visual monitoring and resistance to most acids and bases.
  • Erlenmeyer Design: Narrow mouths with rubber stoppers provide airtight seals, ideal for fermentation, culturing, or titration.
  • Graduations and Labeling: Accurate, durable markings for precise volume measurements.
  • Size Versatility: Options from 500ml for smaller experiments to 1000ml for larger batches.
  • Autoclavable: Safe for steam sterilization up to 121°C, ensuring hygiene without degradation.

These features position Corning flasks as investments in quality, far surpassing budget alternatives in longevity and performance. For those exploring options within Glassware & Labware, Corning delivers unmatched consistency.

Comparing Corning's Top Erlenmeyer Flask Models

Our category highlights two models to suit different needs:

  • Pyrex #4980-500 (500ml): Compact and versatile, perfect for benchtop work, small-scale reactions, or educational demos. Its manageable size fits standard lab shakers and incubators, with a snug rubber stopper for secure closure.
  • Pyrex #4980-1L (1000ml): Scaled up for higher volumes, ideal for pilot-scale experiments, media preparation, or storage. The larger capacity handles bigger workloads while maintaining the same robust Pyrex construction.

Choose the 500ml for space-conscious setups or routine tasks; opt for the 1000ml when efficiency demands greater capacity. Both share identical build quality, but the size difference helps tailor to your workflow. Compared to competitors like those in QWORK Chemistry Flasks, Corning's thermal resilience and clarity provide a clear edge for precision-critical applications.

Common Use Cases for Corning Chemistry Flasks

These flasks excel in diverse scenarios:

  • Chemical Reactions: Mixing reagents under controlled conditions without leaching contaminants.
  • Biological Culturing: Aerobic growth of cultures with easy swirling.
  • Titration and Measuring: Stable platforms for accurate dispensing.
  • Heating Applications: Direct flame or hot plate use with minimal expansion.

Whether in industrial R&D or university labs, they integrate seamlessly into Lab & Scientific Products setups. For alternatives, browse KarterScientific Chemistry Flasks, though Corning's proven track record often wins out.

Frequently Asked Questions

Are Corning Pyrex flasks compatible with all lab equipment?

Yes, their standard Erlenmeyer shape fits most shakers, stirrers, and autoclaves. The rubber stoppers enhance seal compatibility for vacuum or pressure applications.

What sets Corning apart from other brands like QWORK or Karter Scientific?

Corning's Pyrex glass offers superior thermal shock resistance (up to 3x more than soda-lime alternatives) and a heritage of quality control, making it the preferred choice for professional labs over emerging brands.

Which size should I choose: 500ml or 1000ml?

Select 500ml for everyday or small-volume work; go for 1000ml for scalability. Both perform identically in quality—match to your experiment's needs.

Does Corning offer warranties on these flasks?

Corning provides manufacturing defect coverage; contact their support for specifics. Their durability typically outlasts warranty periods in normal use.

How do I care for Corning chemistry flasks?

Clean with mild detergents, autoclave as needed, and avoid sudden thermal shocks. This preserves their clarity and integrity for years.
