JPlast Industrial Filtration Papers

Filter paper – a semi-permeable paper – used to detach fine substances or solids from liquids or air. It is used to reserve separate particles on the exterior and within the matrix of the paper. Our raw materials are imported from  Europe. All the final JPlast filter paper is proudly converted in Johannesburg, South Africa.

 

All our filter paper is imported in Jumbo rolls or in sheet form (ranging from 1mm – 1600mm) and can be converted to either disc or sheet form. The different sizes and shapes of filtration paper are utilized in different filtration apparatus and devices, such as filter presses, vacuum filter apparatus and plain filter funnels. JPlast has a variety of  filter papers, all used for filtration purposes in the laboratories of mines, universities, food industries and various scientific laboratories.

 

1.The different types of filter paper

 

  • Ash-less filtration paper

Ash-less filter paper, beneficial for quantitative routine analysis, is used in circumstances where a specific weight of substrate is required to filter out a liquid. The filter paper goes into a moisture balance, where after it gets burnt away, leaving nothing but the filtered substrate behind. These filters are acid-washed, manufactured from purified pulp and high quality cotton linters and have an exceptionally low ash content of 0.01%, making the cellulose amount 95%.

  • Membrane filtration paper

Membrane filters, otherwise known as ‘membranes’, act as a specific filter that lets water flow through it whilst it catches suspended solids and other substances. It is a microporous plastic film which reserves tiny pieces or microorganisms on the membrane surface. The retention can go very low and are therefore often used in application like microbiological and air pollution. This separation technique is an efficient and acknowledged technique, involving minimal preparation. The process is simple and based on the existence of semi permeable membranes.

  • Glass fiber

This filtration fiber is fabricated from 100% pure borosilicate glass, attaining reported efficiencies of 99.96%. This filter paper is extremely effective, as is does not contain binders or added artificial ingredients which may cause interference to fragile enzymatic or other chemical reactions. Moreover, Glass fiber is equipped with the advantage of reliably providing exceptionally high capacities at high temperatures.

  • Qualitative Filter Paper

 The qualitative grade filtration paper with medium retention and flow rate is widely used for scheduled applications, covering a broad range of laboratory applications. These filtration papers are advocated for analytical use. They are frequently used in routine separation where requiring consistent performance or in qualitative analytical techniques that condition and distinguish materials.

 

JPlast can provide the full range of analytical paper in 13 different types. The turnaround time from conversion of the plant takes 2 – 3 days.

2.Syringe filtration

 Syringe filters is used in conjunction with a syringe. The filter fits snugly on the syringe so that the liquid can be forced through the syringe, whereby the larger particles is retained within the syringe filter. This is used to obtain a filtered liquid and not to obtain the filtered out particles, as the particles will be inside the enclosed filter. The filters are available in two filter porosities 0.2µm and 0.45µm and in a variety of different filter materials namely Nylon, PTFE, PDVF, PES, CA and glass fibre.
