Pyrex 25 ml Glass Beaker

The Pyrex 25 ml Glass Beaker is a high-quality, laboratory-grade glass container. It is typically used for precise measurement, mixing, heating, and stirring of liquids and chemicals in scientific, educational, and industrial settings.

Key Features of the Pyrex 25 ml Glass Beaker:

1. Capacity:
   • The beaker has a capacity of 25 milliliters (ml), making it ideal for small-volume measurements, experiments, or mixing small amounts of liquid substances.
2. Material – Borosilicate Glass:
   • Made from borosilicate glass, Pyrex beakers are known for their durability and resistance to thermal shock. This type of glass can withstand rapid temperature changes without cracking or breaking, which makes it ideal for use in both cold and hot conditions.
   • Borosilicate glass is also resistant to most chemicals, ensuring that the beaker will not react with or degrade when in contact with various acids, bases, or solvents.
3. Graduated Markings:
   • The Pyrex 25 ml beaker typically has graduations (markings) on the side, allowing for accurate measurements of liquids. These markings are often printed or etched to be clear and durable, ensuring readability over time.
   • The graduations help in measuring not just the full capacity but also intermediate volumes for more precise experiments or formulations.
4. Wide, Stable Base:
   • The beaker features a wide base which provides stability when placed on flat surfaces, reducing the risk of tipping over.
   • Its straight sides help with stirring and mixing liquids.
5. Spout for Easy Pouring:
   • The beaker comes with a spout for easy and controlled pouring of liquids, making it practical for transferring liquid without spills, especially when precision is required.
6. Heat Resistance:
   • Pyrex glassware is designed to be heat-resistant, and the 25 ml beaker can be safely used with hot liquids or placed on heating devices like hot plates. It can typically withstand temperatures from -40°C to 500°C, though specific temperature limits should always be confirmed by the manufacturer.
7. Easy to Clean:
   • Pyrex glass is non-porous, making it easy to clean. It can be washed manually or placed in a dishwasher. The smooth surface also helps prevent residues from sticking.
8. Versatile Applications:
   • The Pyrex 25 ml Glass Beaker is ideal for a variety of scientific and industrial applications, including:
     • Chemistry: Used for mixing, heating, and dissolving chemicals.
     • Biology and Lab Work: Used for creating solutions, adding reagents, and conducting experiments.
     • Food and Beverage: This can be used for small-scale recipe testing, especially in laboratories testing food samples.
     • Educational Use: Often used in classrooms for demonstrations in chemistry and science experiments.

Typical Specifications:

• Capacity: 25 milliliters (ml)
• Material: Borosilicate glass
• Graduations: Etched or printed for easy reading of volume measurements
• Temperature Resistance: Can withstand temperatures from -40°C to 500°C
• Dimensions: Typically around 5-6 cm in diameter and 5-7 cm in height (depending on the design)

Conclusion:

The Pyrex 25 ml Glass Beaker is an essential piece of laboratory glassware, known for its high-quality borosilicate glass construction and its resistance to thermal shock and chemical reactions. Its compact size, accurate graduations, and heat resistance make it ideal for precise experiments, small-volume mixing, and laboratory tasks. Whether you’re conducting scientific research, doing educational demonstrations, or working in an industrial environment, the Pyrex 25 ml Glass Beaker is a reliable, durable, and versatile tool.
