Vacufil Bottle Top Vacuum Filter is a high-performance vacuum filtration device designed for rapid and contamination-free filtration of biological and aqueous solutions. This system easily fits on standard laboratory bottles, allowing direct filtration and collection without transfer, reducing contamination risks.
It is widely used in global markets like the USA, UK, Germany, and Europe due to its high flow rate, low protein binding, and reliable sterile performance.
What is Vacufil Bottle Top Vacuum Filter?
Vacufil Bottle Top Vacuum Filter is a ready-to-use sterile filtration unit that connects directly to standard 45mm neck laboratory bottles. It uses a vacuum pump to pull liquid through a membrane, ensuring fast and efficient filtration.
This design eliminates the need for separate funnels and reduces handling steps, making it highly convenient for laboratory use.
Where Is Vacufil Used?
Vacufil Bottle Top Filters are commonly used in:
-
Cell Culture Labs: Filtration of media and buffers
-
Biopharmaceutical Industry: Serum and protein solution filtration
-
Microbiology Labs: Sterile filtration of aqueous samples
-
Research Laboratories: Sample preparation and purification
-
Biotechnology Applications: Processing sensitive biological fluids
They are ideal for applications requiring sterile, high-volume filtration.
Why Choose Vacufil Bottle Top Filter?
Vacufil is designed for ease of use and high efficiency, especially for biological samples.
Key advantages include:
- Direct connection to bottles (no transfer needed)
- Low protein binding membrane
- High flow rate for faster filtration
- Sterile and ready-to-use
- Reduces contamination risk
- Suitable for large volume filtration
Bottle-top systems are widely preferred because they combine filtration + storage in one step, improving workflow efficiency.
Material and Construction
Vacufil Bottle Top Filters are made from high-quality lab-grade materials:
-
Membrane: Polyethersulfone (PES)
-
Housing: Acrylic / Polystyrene
-
Connection: 45mm screw cap neck
This ensures chemical compatibility, durability, and sterile safety.
Working Principle
Vacufil works on a vacuum filtration mechanism:
- The filter unit is attached to a bottle
- Vacuum pressure is applied
- Liquid is pulled through the membrane
- Particles and microbes are retained
- Clean filtrate is collected directly in the bottle
This process ensures fast, efficient, and contamination-free filtration.
Key Features
- Bottle-top design for direct filtration
- Low protein binding PES membrane
- High flow rate and throughput
- Large filtration area
- Sterile (Gamma / EO sterilized)
- Hydrophobic vent to protect vacuum pump
- Ready-to-use disposable unit
Benefits of Using Vacufil Bottle Top Filters
- Eliminates transfer steps → reduces contamination
- Saves time and improves workflow
- Ideal for sensitive biological samples
- Ensures high purity and sterility
- Suitable for large volume filtration
- Provides consistent and reproducible results
