Eisco 100ml Pycnometer Borosilicate Lab Bottle

Description

Product Overview

The Eisco 100ml Pycnometer is a precision laboratory bottle crafted from premium borosilicate glass, a material renowned for its thermal resistance and chemical durability. Calibrated at 20 °C using purified water, this specific gravity bottle delivers highly accurate volume measurements essential for density experiments. Its dimensions—2.4 × 2.4 × 5 inches—and lightweight construction (3.2 oz) make it easy to handle while maintaining the robustness required for repeated use. The product includes a perforated stopper that fits securely, and a flat bottom that prevents tipping, ensuring reliable performance in any lab setting.

Usage

Designed for scientists, educators, and quality‑control technicians, the pycnometer excels in a variety of applications such as determining the density of liquids, verifying material specifications, and conducting calibration checks for analytical balances. Whether you are measuring the density of water, organic solvents, or specialty fluids, the 100 ml capacity provides a convenient volume for both small‑scale research and routine industrial testing. Its calibrated nature eliminates the need for additional correction factors, streamlining workflow and reducing potential sources of error.

FAQ

How do I verify the calibration of the pycnometer?

Fill the pycnometer with distilled water at 20 °C, weigh it on a calibrated balance, and compare the measured mass to the theoretical mass (100 g). The values should match within the balance’s tolerance.

Can the pycnometer be used with corrosive liquids?

Yes, borosilicate glass is highly resistant to most acids and bases. However, avoid prolonged exposure to hydrofluoric acid or strong alkali solutions, as they can eventually degrade the glass.

What is the purpose of the perforated stopper?

The perforation allows air to escape while filling, preventing bubble formation that could affect volume accuracy. It also provides a controlled venting path during temperature equilibration.

Is the pycnometer suitable for high‑temperature applications?

Thanks to the borosilicate composition, the bottle can safely withstand temperatures up to approximately 350 °C, making it appropriate for many thermal stability tests.

How should I clean the pycnometer after use?

Rinse thoroughly with deionized water, followed by a mild detergent if residues remain. Rinse again with distilled water and allow to air‑dry. Avoid abrasive cleaning tools that could scratch the glass surface.
