Glass separatory funnels are known for their clarity, which allows for easy visualization of the separation process. They are also highly resistant to chemical attack and can withstand high temperatures. However, glass funnels are prone to breakage and may not be suitable for use in high-pressure or high-temperature environments.
Plastic separatory funnels, on the other hand, offer a lighter and more durable alternative to glass. They are less prone to breakage and can withstand a wider range of temperatures and pressures. Polypropylene, polyethylene, and Teflon are commonly used plastics in the construction of separatory funnels due to their chemical inertness and resistance to corrosion.
Stainless steel separatory funnels are typically used in applications where high temperatures and pressures are involved. They are highly durable and resistant to corrosion, but they may not offer the same clarity as glass or plastic funnels. |
Applications
Our products
The cylindrical separatory funnel has a wide range of applications in various fields, including chemistry, biology, and pharmaceuticals.
◆ In chemistry, separatory funnels are used for liquid-liquid extractions, which are essential in the purification and isolation of chemical compounds. They are also used in the preparation of organic compounds, where the separation of immiscible solvents is often required.
◆ In biology, separatory funnels are used in the extraction of biological compounds from complex mixtures, such as the isolation of lipids from tissue samples. They are also used in the preparation of biological buffers and media, where the separation of aqueous and organic phases is necessary.

Proper Maintenance and Handling
The proper maintenance and handling of the cylindrical separatory funnel are crucial in ensuring its longevity and performance. Here are some best practices for maintaining and handling separatory funnels:
|
◆ Cleaning and Sterilization: After each use, the funnel should be thoroughly cleaned and rinsed with appropriate solvents to remove any trace of the previous sample. If necessary, the funnel can be sterilized using autoclaving or chemical sterilization methods to ensure that it is free from microbial contamination.
◆ Inspection for Damage: Regularly inspect the funnel for any signs of damage, such as cracks, scratches, or leaks. If any damage is found, the funnel should be replaced immediately to prevent accidents and ensure accurate separations.
◆ Storage: When not in use, the funnel should be stored in a clean, dry place to prevent contamination and damage. It should be stored with the stopcock or valve closed to prevent leakage.
◆ Compatibility with Samples: Always ensure that the funnel is compatible with the samples being processed. Check the material of construction and the chemical resistance of the funnel before use to avoid any potential chemical reactions or contamination.
◆ Proper Usage: Follow the manufacturer's instructions for the proper use of the separatory funnel. Avoid overfilling the funnel and ensure that the stopcock or valve is securely closed during transport and storage. |

Personal protective safety precautions
Wear appropriate protective equipment
Gloves
Wear chemical-resistant gloves when handling chemical liquids, especially if they are corrosive, toxic or irritating. This effectively prevents the liquid from coming into direct contact with the skin, reducing the risk of skin damage.
Goggles
Wearing goggles can protect your eyes from splashing liquids or chemical gases. Safety goggles are especially important when shaking, separating and other operations.
Protective clothing
If the experiment involves large amounts or high concentrations of chemical liquids, protective clothing is recommended. Protective clothing can provide full body protection to prevent liquid splashing on the body and causing contamination or injury.
Face mask or respirator
Wear a mask or respirator when handling volatile toxic or harmful gases. This prevents harmful gases from being inhaled into the body and protects the respiratory system.
Avoid skin contact
Exercise caution
When using a cylindrical separator funnel, be careful to avoid splashing the liquid on the skin or eyes. If accidentally splashed, wash immediately with plenty of water and seek medical assistance.
Understand liquid properties
Before conducting experiments, it is necessary to understand the nature, hazard and emergency treatment of the liquid used. This helps to take appropriate protective measures during the experiment and reduce the possibility of accidents.
Other personal protective measures
Keep the lab environment clean
The experimental environment should be kept clean and orderly to avoid debris accumulation and liquid leakage. This can reduce the occurrence of accidents and ensure the safety of experimental personnel.
Follow laboratory rules and regulations
Strictly abide by the laboratory rules and regulations and operating procedures, do not arbitrarily change the experimental steps or operating conditions. This helps ensure the safety and reliability of the experiment.
Attend regular safety training
Experimental personnel should regularly attend safety training to understand the latest safety knowledge and operating skills. This helps to improve the safety awareness of the experimentalists and reduce the occurrence of accidents.
Personal protection for specific experiments
Flammable and explosive test
When carrying out flammable and explosive experiments, in addition to wearing basic protective equipment, special attention should be paid to stay away from the fire source and be equipped with corresponding fire extinguishing equipment.
Toxic and harmful experiments
When dealing with toxic and harmful liquids, in addition to wearing protective equipment such as gloves and goggles, special attention should be paid to ventilation to ensure air circulation in the laboratory.
In short, when conducting experiments with cylindrical separation funnels, experimenter should always pay attention to personal safety, wear appropriate protective equipment, avoid skin contact, and follow laboratory rules and regulations and operating procedures. These measures can effectively reduce the risk of the experiment and ensure the health and life safety of the experimentalists.
