Superior Material and ManufacturingFabricated from transparent borosilicate glass, these bottles offer remarkable resistance to chemicals and thermal shock, which preserves sample integrity during experiments. Each stopper is perfectly ground for a secure fit, minimizing contamination risk and evaporation. Their smooth surface ensures effortless cleaning, maintaining high standards of laboratory hygiene.
Designed for Accurate Laboratory WeighingWithout graduation marks and featuring a lightweight build, these bottles are tailored for precise weighing of solid substances on analytical balances. Their cylindrical or flat bottom design enhances stability during measurements, ensuring consistent accuracy. Compatibility with most balances and their ease of handling make them essential for analytical processes.
Versatile and Convenient Packaging OptionsCustomers can choose from individual or bulk packaging, accommodating both small-scale laboratories and large research facilities. This flexibility simplifies procurement and supports efficient inventory management, catering to laboratories, exporters, and academic institutions across India and abroad.
FAQs of Weighing Bottles:
Q: How should weighing bottles with ground glass stoppers be properly sterilized?
A: These weighing bottles are made from borosilicate glass and can withstand autoclave sterilization at temperatures up to 400C. Before sterilizing, remove the ground glass stopper to ensure thorough cleaning and steam penetration, then reassemble after both parts have cooled.
Q: What are the primary benefits of using ground glass stoppers in these weighing bottles?
A: Ground glass stoppers provide an airtight seal that prevents sample contamination and evaporation, making them ideal for precise weighing and storage of solid chemicals in laboratory settings.
Q: When is it recommended to use weighing bottles without graduation marks?
A: Use these bottles when you need to measure the total mass of a substance rather than its volume. The absence of graduation marks ensures that weighing is not affected by inaccurate visual readings, supporting applications that demand precision mass measurements.
Q: Where are these lightweight laboratory weighing bottles typically used?
A: These bottles are commonly used in chemical laboratories, research centers, and academic institutions where precise weighing of powders or solid samples is essential. Their compatibility with most laboratory balances makes them versatile for various scientific environments.
Q: What is the correct process for using these bottles on an analytical balance?
A: First, place the empty, clean bottle with the ground glass stopper on the balance and tare the scale. Add the desired solid, recap the bottle, and weigh again to obtain the exact sample mass. This process ensures high accuracy and repeatability.
Q: How does borosilicate glass construction benefit chemical laboratory applications?
A: Borosilicate glass is highly resistant to thermal shock and chemical corrosion, making these bottles safe for use with a wide variety of reagents and at high temperatures. This ensures longevity and preserves sample purity during experiments.
