Bottle Weighing - Short Form

A squat weighing bottle is a specific type of small, cylindrical container used in a laboratory for accurately weighing solid or liquid chemical samples. The term "squat" refers to its shape: it is generally wider in diameter and shorter in height than the "tall form" weighing bottle.  

Key Features and Design 

• Shape: It has a low center of gravity due to its wider base and shorter height, which makes it more stable and less prone to tipping over during transfer or while on a balance pan.
• Material: Typically made from borosilicate glass, which offers chemical resistance and can withstand heating (e.g., for drying samples in an oven before weighing).
• Lid: It features a tight-fitting, ground-glass stopper (lid) that creates a sealed environment.
• Wide Opening: The wide mouth makes it easy to add or remove solid samples without spilling.
• This seal is crucial for:
• Preventing the sample from absorbing moisture from the air (hygroscopic substances).
• Preventing the loss of volatile substances through evaporation.
• Containing the sample securely during weighing and transport.
• Flat Bottom: The flat bottom ensures stability on the balance pan or workbench.
• Various Sizes: Squat weighing bottles are available in a range of capacities and diameters to accommodate different sample sizes.

Purpose and Applications

The primary use of a squat weighing bottle is in analytical procedures requiring high accuracy: 

• Accurate Weighing: The bottle's low, consistent weight allows for precise taring on an analytical balance when measuring solid samples.
• Sample Transfer: After weighing, the entire bottle and sample can be transferred to the reaction vessel or dissolution flask, ensuring all the weighed material is transferred without loss.
• Drying: Samples can be placed in the bottle and heated in an oven for drying before weighing.
• Storage: Used for short-term, secure storage of small quantities of chemicals.
