Product description
A nylon membrane capsule filter is a disposable filtration unit designed for precision filtration of aqueous solutions and alcohol-based solvents. The capsule integrates membrane filtration media and housing into a sealed unit, enabling fast installation without the need for a separate filter housing.
Technical overview
Nylon membranes combine hydrophilic properties with good compatibility for aqueous solutions and alcohol-based solvents. These membranes are commonly used for fine particle removal, clarification and terminal filtration in laboratory and small-scale process applications.
The capsule configuration simplifies filter handling by providing a pre-assembled filtration unit with defined pore sizes and connection options.
Operating principle
During operation, the process fluid enters the capsule through the inlet connection and flows through the nylon membrane. The membrane contains controlled pores that retain particles, bacteria and suspended solids according to the selected micron rating.
The filtered liquid exits through the outlet connection while contaminants remain retained in the membrane structure.
Material options
Typical construction materials include:
- Filter media: Nylon membrane
- Support layers: Polypropylene
- Capsule housing: Polypropylene
- Optional filling bell: Polycarbonate
These materials provide compatibility with aqueous solutions and alcohol-based fluids commonly used in laboratory environments.
Available micron ratings
Typical pore size options include:
- 0.1 µm
- 0.2 µm
- 0.45 µm
- 0.65 µm
- 1.0 µm
- 3.0 µm
The selected pore size determines the level of particle and microbial retention required for the filtration application.
Design and construction
Capsule filters integrate membrane media and housing into a single disposable filtration device.
Typical design characteristics include:
- Hydrophilic nylon membrane
- Low extractables for laboratory applications
- Multiple inlet and outlet connection options

Configuration and quotation
To specify a nylon capsule filter, the following parameters should be defined:
- Required pore size (micron rating)
- Capsule length (1.5", 2.5", 5" or 10")
- Connection type
- Process liquid type
- Operating pressure and temperature
Providing these parameters allows the capsule filter configuration to be matched to the filtration system.
