Like textiles and other production industries that utilise organic components, paper mills use bacteria and fungi intentionally during production. This occurs when toxic wastewater needs degrading. Bacteria is used for this purpose (biotreatment). It also occurs when fungi is intentionally used in pulp bleaching / biopulping. Fungi was initially seen as a nuisance but its uses as an alternative to chemicals are becoming more widely acknowledged.

Also, like the textile industry and others, unwanted contaminants / micro-organisms can degrade and be harmful to the product. The appearance (discoloration) and odour of the product can be compromised. As well as this, airborne bacteria and moulds can be released from the paper dust. This can especially affect workers in paper mills. Machines can also be affected by microbiological activity as biofilm build up can damage machinery or cause faults.

Due to the above reasons, most paper mills regularly run microbiological tests.

Food grade paper / packaging in particular needs to be monitored closely.

Contamination can be caused by machinery, raw materials, workers. Paper is produced in an open environment so microbiological contamination can come from anywhere.

Often pulp and paper processing machines are swabbed and tested as well as some paper / pulp samples.

Coliforms are some of the most commonly found contaminants in paper mills. With this in mind, these dipslides test for coliforms and total count. If you would like to instead test for total count bacteria and yeast and moulds, you can purchase our Nutrient and Pulp / Paper agar dipslides here: Nutrient & Pulp / Paper.

Sulfate reducing bacteria can also be a problem in paper mills, causing corrosion in machinery. If you would be interested in purchasing a sulfate reducing bacteria test, you can do so here: SRB.

Flexible paddle

Flexible Paddle

Each dipslide features a virtually unbreakable and flexible paddle allowing for even, full surface testing.

Easy run off design

Easy Run Off Design

Due to the design of the dipslide, fluids will drain off quickly during testing.

Recessed Handle

Recessed Handle

Each slide has a handle built into the lid that is recessed to help keep your fingers dry during testing.

Side Indicator

Side Indicator

One side of the slide will have a circle indicator so you know which side was used for testing which type of contaminant.

Dual sided paddle

Dual Sided

Each dipslide is dual sided to allow multiple contamination testing with one test.

Thick reliable Agar

Thick Reliable Agar

Each agar is thick (approx 4mm) and raised above the dipslide to allow for easy surface testing.

About the Pulp / Paper Dipslides

These dipslides have MacConkey 3 agar on one side and Plate Count Agar on the other. The MacConkey 3 agar tests for coliforms and the Plate Count agar tests for a general count of viable aerobic organisms.

These dipslides will assist you in determining the levels of aerobic bacteria and coliforms present in your samples.

How to use Paper Mill Dipslides

Remove Pulp / Paper slide from tube

Step 1 : Remove slide

Carefully remove the sterile Pulp / Paper dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).

Surface testing

Step 2 : If Surface Testing

For surface testing, press the Pulp / Paper dipslide onto the surface. If needed, place a finger on the bottom of the slide (on the plastic, not the agar) to apply extra pressure.

Liquid Testing

Step 2 : If liquid testing

For liquid testing, immerse the Pulp / Paper dipslide into the fluid for 10 seconds then remove and allow to drain for a few seconds.

Swab Testing

Step 2 : If swab testing

Apply a sample of the test substance to a sterile swab and gently apply to the agars.

Incubate the dipslide

Step 3 : Incubate Slide

Label the tube with the included stickers then place the slide into an incubator and allow to incubate.

compare dipslide results

Step 4 : Compare results

Count the amount of colonies that have grown on the slide and compare them to the comparison chart provided.
