Flat-bottom flasks are mostly used for extraction reactions, solvent extraction, cooling reactions, reactant mixing and mixed reactions. Because it has a flat membrane surface, it has a larger surface area and can improve the reaction conversion rate while reducing the excessive bubbles in the chemical reaction process, so it can be used in experiments with longer reaction times. Advantages: 1. High Temperature Resistance ：-200 to +260℃ 2. Ultra low dissolution and precipitation 3. Low blank value of metal elements 4. Strong acid and alkali resistance 5. Excellent chemical stability Tel：+86 13913985644 WhatsApp：13913985644 Gmail：adanjbzh@gmail.com Store website：https://www.njbinglab.com
