A Membrane Filter Assembly with a Silicone Cork, Cup, and Clamp (without a flask) is a versatile setup often used in laboratory filtration processes. Here's a detailed overview of each component and its function:

• Cup (Filter Holder):
  Holds the membrane filter and the liquid sample to be filtered.
  Made of materials like stainless steel, glass, or plastic, depending on the application.
  Features a perforated base to support the membrane filter.
• Silicone Cork:
  Acts as a seal between the cup and the filtration system.
  Provides an airtight fit, ensuring no leakage during the filtration process.
  Offers flexibility and durability, suitable for high and low temperatures.
  Compatible with vacuum or pressure filtration setups.
• Clamp:
  Secures the cup and silicone cork together.
  Ensures a tight, leak-proof connection.
  Typically made of stainless steel or other corrosion-resistant materials.
