About this item

• Intended use: precise dropwise addition enables controlled, dropwise addition of liquids into conical flasks during solid–liquid reactions for reproducible reagent dosing
  
• Long-stem design: deep insertion 250 mm long tube with wide-mouth funnel allows deep flask penetration, reducing splashing and vapor loss
  
• Flow control: slow, steady delivery stem geometry provides controlled, slow flow for accurate metering and improved reaction kinetics management
  
• Material: borosilicate glassware made from borosilicate glass for excellent optical clarity, thermal stability, and broad chemical resistance
  
• Cleaning & maintenance: residue prevention rinse immediately after use with lab detergent; inspect and dry to prevent carryover and contamination
