Bottle Top Filter

Bottle top filter is a laboratory consumable commonly used for liquid or gas filtration. It uses vacuum suction to accelerate the filtration process and is widely used in chemistry, life sciences, environmental monitoring and other fields. It is suitable for a variety of filtration needs such as water samples, air samples, cell culture fluids, etc.

Bottle top filter for sale: Nylon, MCE, PES, CA, PVDF.

Pore size: 0.22um, 0.45 um, 0.1um.

With the upper cup and solution bottle available.

MOQ: 1 CARTON.

Feature of Bottle Top Filter

High-efficiency filtration: The vacuum system is used to significantly improve the filtration speed.
Multiple specifications: Suitable for different containers and capacity requirements, common specifications include 100mL, 250mL, 500ml bottle top filter, 1000 ml bottle top vacuum filter etc..
High pressure design: Made of corrosion-resistant materials, suitable for the filtration of various chemical reagents.
Matching filter membrane: Can be used with filter membranes of different pore sizes (such as bottle top filter 0.22, 0.45μm) to meet different filtration accuracy requirements, nalgene bottle top filter, pes bottle top filter, pvdf bottle top filter and other bottle top filters are available .
Economical and efficient: Disposable filter to avoid tedious cleaning and reduce the risk of contamination.

Bottle-top vacuum filter system is a laboratory tool used to filter and sterilize liquids, often for cell culture media, buffers, or other aqueous solutions. This system combines a filter unit with a vacuum source, allowing rapid filtration while maintaining a sterile environment.

Components

1. Bottle Top Filter Unit: This is the top part of the system, typically made from sterilizable plastic like polystyrene, and contains the membrane filter. It is designed to fit securely onto a receiving bottle.

2. Membrane Filter: The membrane (often made of materials like cellulose acetate, nylon, or PVDF) is available in different pore sizes (e.g., 0.22 µm for sterilization, 0.45 µm for particle removal).

3. Receiving Bottle: A sterile bottle placed beneath the filter unit that collects the filtered solution.

4. Vacuum Connection Port: The side port on the filter unit allows for attachment to a vacuum source, which pulls the liquid through the filter and into the receiving bottle.

How to Use Bottle Top Filter

Connect the vacuum filter to the vacuum pump and ensure a good seal.
Pour the liquid or gas to be filtered into the upper container of the filter.
Turn on the vacuum pump, start the filtration process, and wait for the liquid or gas to pass through the filter membrane.
Stop the vacuum pump and remove the filtered liquid or sample container.
After filtration, clean the vacuum filter or replace it with a new filter membrane and discard the used part.
