About Den-sity Bottle (G-ay-Lu-ssac Type)
A density bottle (Gay-Lussac type) is a glass pycnometer for determining liquid density, featuring a precision-ground, stopper with a capillary tube for overflow.Key specifications include being made of borosilicate glass with either a uncalibrated or calibrated volume (e.g., 10 mL, 25 mL, 50 mL) specified with high accuracy, and designed to contain (TC) a specific volume of liquid.The stopper is typically a ground glass stopper with a joint (e.g.,NS 10/19)and a capillary, with the top ground and polished.
Key Features & Specifications
- Material:Borosilicate glass.
- Type:Narrow-mouth, round bottle with a ground glass stopper.
- Stopper:Ground-glass stopper with a capillary tube that allows excess liquid to escape when the bottle is filled to its maximum volume.The stopper's top is ground and polished for precision.
- Joint:May feature aground glass (NS) joint.
- Purpose:To determine the density of liquids with known volume.
Calibrated vs. Uncalibrated
-
Calibrated Density Bottles:
Have a precise, pre-determined volume (e.g., in cm) specified to several decimal places.They may also come with an individual certificate detailing their volume.
-
Uncalibrated Density Bottles:
While having a designated volume, they are not calibrated with the same level of precision as calibrated bottles and may not come with a certificate.
- Standard capacities for both calibrated and uncalibrated models include 10 mL, 25 mL, 50 mL, and 100 mL.

FAQ's of Den-sity Bottle (G-ay-Lu-ssac Type):
Q: How is the Den-sity Bottle (Gay-Lussac Type) used to measure liquid density?
A: The bottle is filled with a specific liquid up to the marked calibration level, weighed, and then emptied and weighed again. The difference in mass assists in determining the density, following the Gay-Lussac method.
Q: What laboratory applications benefit from this type of density bottle?
A: This bottle is commonly used for precise liquid density measurement in research, quality control, educational experiments, and chemical analysis, due to its accuracy and reliability.
Q: When should I select a bottle with Class A or Class B marking tolerance?
A: Choose Class A for experiments where highest accuracy is critical, such as research and calibration work. Class B suffices for routine laboratory procedures or educational purposes.
Q: Where is this density bottle suitable for mounting and use?
A: The bottle is designed for benchtop use in laboratory, research, and educational facilities with ambient temperature and humidity conditions.
Q: What is the benefit of using borosilicate glass in this density bottle?
A: Borosilicate glass offers superior chemical resistance, thermal durability, and hardness, ensuring longevity and compatibility with a wide range of laboratory liquids.
Q: How do the permanent white enamel calibration markings enhance usability?
A: These markings ensure clear visibility and accuracy during measurement, minimizing errors that can result from faded or worn labels.
