A 50 mL glass beaker is a cylindrical laboratory vessel used for measuring, stirring, and heating small volumes of liquids. Typically crafted from heavy-duty, heat-resistant borosilicate 3.3 glass, it features clear graduation markings, a flat base, and a pouring spout for clean, spill-free transfers.
Key Specifications & Features
- Material: 3.3 Borosilicate glass.
- Graduations: Often marked at 10 mL increments up to 40 or 50 mL.
- Dimensions: Typically 42-45 mm in outer diameter and 60-63 mm in height.
- Heat Tolerance: Can withstand temperatures ranging from roughly -70C up to 400C without shattering due to thermal shock.
- Design: Low-form, straight-sided cylindrical shape with a beaded rim and integrated pouring spout
- Common Applications
-
- Liquid Measurement: Used for holding and estimating precise fluid volumes (though less accurate than graduated cylinders).
- Heating: Suitable for warming liquids, dissolving solids, or boiling using a hot plate or Bunsen burner.
- Mixing & Prep: Perfect for combining reagents, stirring solutions, or preparing small batches of solvents.
Robust Borosilicate Glass ConstructionManufactured using high-grade borosilicate glass, these beakers offer supreme resistance to thermal shock and chemical corrosion. This makes them suitable for repeated heating, direct flame use, and handling a wide range of chemical solutions, ensuring reliable performance in demanding laboratory settings.
User-Friendly and Practical DesignThe glass beakers feature a defined pouring spout for spill-free transfers and clear white graduation markings for accurate measuring. Their stackable form saves space in busy labs, and the smooth polished finish allows for effortless cleaning after every use. With capacities from 100ml up to 1000ml, there's a suitable size for every application.
Effortless Sterilization and CleaningThese beakers are autoclavable for sterile laboratory work and compatible with common laboratory detergents for regular cleaning. Their tough borosilicate glass construction withstands repeated sterilization and dishwasher cleaning without compromising integrity or clarity.
FAQ's of Glass Beakers:
Q: How should I clean and sterilize glass beakers after laboratory use?
A: Glass beakers can be cleaned easily with standard laboratory detergents and are dishwasher safe for thorough cleaning. For sterilization and use in sterile environments, these beakers are fully autoclavable, allowing safe and repeated high-temperature autoclave cycles.
Q: What types of laboratory applications are these glass beakers suitable for?
A: These beakers are ideal for mixing, heating, and measuring liquids and solutions in chemical laboratories and scientific research. Their high chemical and thermal resistance makes them versatile for a wide range of experimental and preparation tasks.
Q: When should I choose a 500ml beaker with 50ml graduation intervals?
A: A 500ml beaker with 50ml increments is perfect when you require moderate volume measurements and need precise reading with 5% accuracy. It's commonly used when preparing solutions, mixing reagents, or conducting sample dilutions in routine laboratory processes.
Q: Where can these laboratory glass beakers be used and stored?
A: These beakers are suitable for use in chemistry labs, research facilities, educational institutions, and industrial laboratories across India. Their stackable design allows for efficient storage, minimizing required shelf space.
Q: What benefits does borosilicate glass provide for laboratory beakers?
A: Borosilicate glass offers excellent resistance to thermal shock and most chemicals, ensuring durability and long life even under direct flame or hotplate heating up to 400C. This reduces breakage and maintains clarity and strength after repeated use.
Q: How does the defined pouring spout improve laboratory work?
A: The precisely shaped pouring spout ensures controlled and spill-free transfer of liquids, reducing waste and improving accuracy when decanting or dispensing samples into other vessels during experiments or storage.
