The Kjeldahl flask from Rama Scientific Glass industries is a precision laboratory vessel made from borosilicate glass 3.3, designed specifically for nitrogen and protein analysis via the Kjeldahl digestion method. Available in volumes of 100 mL, 250 mL, 300 mL, 500 mL, 800 mL, and 1000 mL, each flask features a long, narrow neck to reduce splashing and a rounded bottom for even heat distribution during acid digestion at temperatures up to 400°C. The design adheres to standard laboratory ergonomics for safe handling and compatibility with heating mantles and digestion blocks.
Borosilicate glass 3.3 is the industry standard for high-temperature chemical applications due to its low coefficient of thermal expansion and resistance to hydrofluoric acid, strong alkalis, and prolonged exposure to concentrated sulfuric acid. This material ensures dimensional stability and minimizes the risk of cracking under rapid thermal cycling. The flask's wall thickness and neck geometry are typical for Kjeldahl systems used in food, pharmaceutical, and environmental testing labs, where sample integrity during digestion is critical.
These flasks are purchased by analytical laboratories in agriculture, dairy, feed, and pharmaceutical sectors that require reliable nitrogen content measurement. They are commonly shipped in bulk, packed in cardboard with internal foam dividers to prevent breakage. Trade terms are typically FOB Ambala port, with minimum order quantities negotiated per batch. Lead times vary by volume and are confirmed directly with the supplier before production.

Before ordering, verify the flask’s material grade is borosilicate 3.3 and not soda-lime glass, which cannot withstand prolonged acid digestion. Request a sample to test for thermal shock resistance by heating to 200°C and plunging into cold water. Confirm the neck length and diameter match your digestion block’s specifications to avoid compatibility issues. Do not rely on claims of ISO or CE certification unless the supplier provides a copy of the certificate.
Trade terms are typically FOB Ambala or CIF port of destination, with lead times ranging from 15 to 30 days depending on order size. Payment is commonly by T/T in advance or LC at sight. Packaging must include internal foam dividers and outer cartons rated for 15 kg gross weight. Confirm the number of units per carton and total pallet dimensions for shipping cost estimation. Lead time may extend during monsoon season due to logistics delays in northern India.
Perform incoming inspection by checking each flask for cracks, bubbles, or uneven wall thickness under bright light. Use a micrometer to verify wall thickness at three points on the bulb. Confirm volume accuracy by water displacement at 20°C. Request a Certificate of Conformity for each batch, specifying material type, volume tolerance, and test method. Retain samples from each shipment for quality comparison in future orders.
