Feature: 1. Multi Purpose: The conical flask can not only be used to store chemical reagents, but also can be used as a culture bottle for bacteria, such as fecal culture and incubation in the prevention and treatment of blood sucking diseases. 2. Stable Placement: The bottom of the beaker is large and small, which is easy to clean, even when tilted and shaken, and the solution is not easy to overflow. 3. Long Neck Length: The neck of the conical flask is long, and the area where the solution adheres to the mouth of the bottle is small. Sometimes it can be used for simple and rough color comparison. 4. Easy to Observe. Due to the large slope of the conical flask, the changes in the flask are observed during the assay operation, which is wider and clearer than the plane observation. 5. Borosilicate Glass: The glass used in the conical flask is borosilicate glass, which has much better chemical properties than ordinary glass and is very suitable for chemical purposes. Specification: Item Type: Erlenmeyer Flask Material: Borosilicate Glass Uses: Ideal for laboratory projects or kitchens, most acids, bases and many common solvents Capacity: 50ml,100ml,250ml,500ml.
