Filters for Macherey-nagel syringe type Chromafil PA (Pack of 400 pieces)

FILTERS FOR SYRINGE MACHEREY-NAGEL

TYPE CHROMAFIL PA MODEL AO 20-45 / 25

Facilities for CHROMAFIL syringe filters are used for filtration of the material in suspension in liquid samples

Advantages

- Housing PP

- Better stability to solvents compared to acrylate and polystyrene filters

- Shells ultrasonically sealed, not glued

- No plug-in component of the glue

-Filtration Possible in both directions, the liquid can not bypass the membranes Luer lock on the input side

- Secure connection on the high pressure side

- Output Standard LuerLuer for filters to be 3 mm and 25 mm, MiniSpike luer with low dead volume and small outer diameter for 15mm filters

- The flow of liquid is equally distributed over the entire surface of the membrane: this allows a better use of the total area; the filters do not clog up quickly; it has high flow efficiency

- Color coding: The filters with 0.2μm pores have a yellow upper housing, in those with 0.45μm porosity is rather colorless; the different types of membranes differ due to different color

- Low dead volume ~ 80μl for 25mm, 12μl for 15mm, 5uL to 3 mm.

Technical data:

The membrane housing is polypropylene (PP).

This material is very resistant towards most solvents and has a low level of extractables. So it can be used with almost all solvents, acids and bases.

The especially thick rim is ideal for use with laboratory robots

The input and the output of the filter can be connected, via a special adapter, to the columns CHROMABOND® for the selective preparation of the sample.

All filters can be autoclaved at 121 ° C and 1.1 bar for 30 minutes.

Hydrophilic membrane is characterized by a very low adsorption.

And 'it suggested for the filtration of liquids by means of aqueous and polar organic / aqueous

Membrane diameter 25 mm

400 pieces pack

Available in different porosities:

- Porosity 0.20 µm color: yellow above, green base

- Porosity 0.45 µm color: above natural, green base
