Overview
Erlenmeyer Flask are frequently employed glassware in laboratories. Composed of high borosilicate glass, they exhibit exceptional chemical and thermal stability, being capable of withstanding the corrosion of multiple chemical reagents, adapting to significant temperature variations, and being less prone to fracture. The conical shape of the flask facilitates the mixing of liquids and the uniform distribution of heat. The wide-mouth enables the addition of reagents, stirring, and the observation of reactions with ease. The flat bottom ensures stable placement. They are extensively utilized in chemical, biological, and analytical experiments.
Features
1. High-temperature tolerance: Capable of withstanding relatively high temperatures and abrupt temperature variations of up to 200℃.
2. Low coefficient of thermal expansion: It has a low coefficient of thermal expansion, thus being less prone to cracking or deformation caused by temperature differences.
3. Wide-mouth: Facilitates the addition of substances, stirring, and cleaning.
4. Conical flask body: Ensures stable placement, is less likely to topple over, and reduces the possibility of liquid splashing during oscillation.
5. Uniform wall thickness: Enhances heat resistance and pressure resistance.
Technical data
Working Environment Conditions:
1. Temperature: The operating temperature can reach 280℃, with an instantaneous peak of 300℃. It can withstand a sudden temperature change of 200℃, and the temperature range is from -200℃ to +600℃.
2. Chemical Environment: It has a first-grade resistance to acids, a second-grade resistance to alkalis, and a first-grade resistance to water.
3. Physical Environment: It possesses high mechanical strength, good impact resistance, and superior light transmission performance.
Precautions:
1.Inspection: Before usage, meticulously inspect the conical flask for any cracks, damages, or other defects. If any are detected, it should not be utilized to prevent breakage and subsequent risks during the experiment.
2. Uniform Heating: During heating, ensure uniform heat distribution on the conical flask. Generally, an asbestos net should be used to avoid local overheating and cracking. Dry heating is prohibited.
3. Control of Liquid Volume: The liquid contained within the flask should not exceed two-thirds of its volume. When heating corrosive liquids, the mouth of the flask should be covered with a watch glass.
4. Prevention of Excessive Temperature Differences: Do not place a heated conical flask directly on an overly cold countertop to avoid sudden glass fractures due to drastic temperature changes.
5. Storage: Immediately after usage, wash, dry, and store the flask upside down. It is not advisable to store chemical reagents in it for an extended period.
