• 1. All flasks are made of 3.3 borosilicate glass, hand blown and polished for perfect fit.
• 2. Preserve the solvent. After the solvent extraction is completed, the solution is heated. The volatile solvent is condensed through the condenser and re-entered into the extraction environment to start a new extraction process.
• 3. The degree of completion of the extraction is very high. It can be removed by adding several solvents and has a high usage rate. The perfect combination of organic chemistry laboratory, , fractionation, separation, and synthesis.
• 4. All vials are made of 3.3 borosilicate glass, which is perfectly fixed after being blown and polished.
• 5. If there are defects in quality or shipping, please write two photos, a light, a blanket, a refund or a free replacement for your choice.
