An Amber 2500ml (2.5 Litre) Borosilicate Glass Lab Bottle is a heavy-duty, large-volume container designed for bulk chemical storage, solvent recycling, or large-batch culture media preparation. It utilizes dense Boro 3.3 glass walls to safely handle the high mechanical stresses of carrying over 2.5 kg of liquid while maintaining critical UV-blocking properties up to 500 nm.Core Technical SpecificationsMaterial: Borosilicate Glass 3.3 (USP/EP Type I neutral glass).Capacity: 2500 mL / 2.5 Litres (typically graduated in 100 mL or 200 mL increments using permanent white enamel).Dimensions: Approximately 280 mm to 300 mm in height and 135 mm to 140 mm in outer diameter.Neck Specifications: Commonly steps up to a larger GL 45 or a high-flow CLS 80 / GL 80 wide-mouth thread to facilitate easier pouring of bulk liquids.Weight: Empty bottle weight typically ranges between 1.0 kg and 1.3 kg; handle with care when fully loaded.Safety Protocol: Due to mass and thermal inertia, large 2.5L bottles require slower cooling phases during autoclaving to prevent thermal shock cracks.
