Laboratory glassware is manufactured using different types of glass materials, each designed for specific laboratory applications. Understanding these materials helps in selecting the right glassware for safety, accuracy, and durability.
Types of Glass Materials Used in Laboratories
Borosilicate Glass 3.3
Borosilicate 3.3 glass is the most commonly used laboratory glass due to its excellent chemical resistance and ability to withstand thermal shock. Thicker-walled borosilicate glass is often preferred for high-pressure or vacuum applications.
Amber-Coloured Glass
Amber-coloured glass is a specialized form of borosilicate glass (3.3) with a dark brown surface that blocks harmful ultraviolet and infrared radiation. It is widely used for storage bottles containing light-sensitive or reactive chemicals.
Soda Glass
Soda glass is one of the most common and economical types of glass used in everyday containers for food and beverages. Due to its high thermal expansion and uneven surface, it is less suitable for laboratory applications.
Quartz Glass
Quartz glass can withstand extremely high temperatures and is used only for specialized laboratory applications that require operating temperatures above 600 °C. Due to its high cost, it is not commonly used for routine lab work.
Scientific Glassware & Their Applications
For more than three decades, YASH INSTRUMENT COMPANY has been one of India’s leading manufacturers and suppliers of scientific laboratory glassware. Below is an overview of commonly used laboratory glassware and their applications.
Beakers
Beakers are versatile glass containers used for holding, mixing, and heating liquids. Although they include graduated markings, these are approximate and may vary by up to 5%. Yash Instrument Company manufactures beakers in low-form, tall-form, and conical designs.
Erlenmeyer Flasks
Erlenmeyer flasks feature a flat bottom and narrow neck, making them ideal for heating and mixing liquids. They are easier to seal compared to beakers and are commonly used in chemical reactions and storage.
These flasks are available with narrow or wide necks and may include approximate volume markings within ±10% accuracy.
Boiling (Florence) Flasks
Boiling flasks are spherical, thick-walled flasks designed for uniform heating. Made from borosilicate glass, they can withstand direct flame heating and are commonly used in boiling and distillation processes.
Yash Instrument Company manufactures boiling flasks in 250 ml and 500 ml capacities.
Volumetric Flasks
Volumetric flasks are used for precise solution preparation. Each flask has a single calibration mark for an exact volume. These flasks are not intended for heating, as temperature changes can affect accuracy.
We manufacture both Class A and Class B volumetric glassware in compliance with international standards.
Funnels
Glass funnels are essential for transferring liquids safely between containers. Specialized funnels such as separatory funnels are used for extraction and filtration.
Our range includes filtering funnels, powder funnels, Buchner funnels, and Buchner funnels with drip cones, all made from high-grade borosilicate glass.
Graduated Cylinders
Graduated cylinders provide accurate liquid measurement, typically within 1% of the actual volume. Safety bumper rings help prevent breakage if the cylinder is tipped.
Yash Instrument Company manufactures measuring cylinders, mixing cylinders, and Nessler cylinders in various configurations.
Pipettes
Pipettes are used for delivering precise volumes of liquid. Common types include Volumetric Bulb Pipettes, Mohr Pipettes, and Serological Pipettes.
We manufacture Class A pipettes supplied with calibration certificates to ensure accuracy.
Crystallisation Dishes
Crystallisation dishes have a wide diameter and shallow height, allowing rapid evaporation of solutions. They are commonly used for recrystallization and bath operations.
Burettes
Burettes are precision glass tubes fitted with a valve for controlled liquid delivery. They are widely used in titration experiments.
Yash Instrument Company manufactures Class A/AS burettes with calibration certificates.
Test Tubes
Test tubes are used for storing, heating, and testing small samples. They are economical and made from borosilicate glass 3.3.
Available in rimmed and non-rimmed designs, test tubes are offered in various sizes to suit different laboratory needs.
