Heavy wall Brosilicate Glass Lab Funnels Powder funnel separatory funnel by hand-blowing

タイトルまたは説明

Laboy glass funnels are heavy wall designed, made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glass and annealed at **0 degree Celsius, can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.
The funnels included buchner funnel,filter funnel,separatory funnel,pressure equilizing funnel,additional funnels, these funnels can be used in the organic chemistry lab for distillation,extracting,separating process.
