Weighing bottles are the equipment that is used for the accurate weight of solids in the laboratory. Most of them are made of glass. They are usually cylindrical with a flat bottom. Impermeable seal stoppers on top help to keep the content unadulterated.

They are translucent, anti-static, and polystyrene. It can be easily flexed so the weighing, dispensing, or pouring of liquids or solids are done smoothly. Its flat bottom resists tipping. Biologically inert resistant to most dilute acids, aqueous solutions, and alcohol bases. 

They are used for weighing, sampling, dispensing, storage processing, evaporating, or in any general laboratory application, They have a flanged edge with a curled lip.

Borosilicate glass funnel with tapered poring neck for micro transferring of solid and liquid, flat bottom keep funnel from while weighing. To be used as weighing dish and sample transfer funnel.

For analytical balances - Sufficient body to support sample - Smooth textured to avoid trapping material - Does not absorb moisture
