FAQs

Q1: Should I choose the Flat type or the Tall type weighing bottle?

A1: It depends on your experiment. The Flat type has a wide surface area, making it perfect for moisture analysis because it allows powders to spread out thinly and dry much faster in an oven. The Tall type occupies less space on your balance pan and is ideal for standard weighing and transferring of non-drying liquids or solids.

Q2: Can I place this weighing bottle inside a high-temperature drying oven?

A2: Yes, absolutely. It is constructed from thickened, heat-resistant glass explicitly for gravimetric analysis. However, remember to either remove the lid or place it slightly ajar before putting the bottle into the oven to allow moisture to escape and prevent pressure buildup.

Q3: Why is the lid frosted instead of clear?

A3: The frosting on the lid and the inner rim of the bottle is a result of precision glass grinding. This process creates a microscopically interlocking surface that provides an absolutely airtight seal without using rubber gaskets. This ensures your dried samples do not absorb ambient moisture while cooling down in a desiccator.

Q4: How do I handle the bottle without affecting the weight?

A4: The oils and moisture from your bare hands can add microscopic weight to the glass, ruining high-precision analytical measurements. You should always handle the weighing bottle using clean laboratory tongs, tweezers, or lint-free gloves when transferring it to and from the analytical balance.
