Push the other two gaskets into place around the sintered support disc. The graduated funnel screws clockwise into position.

  • Page 29: Section 2: Preparing Bacteriological Media In A Laboratory Facility

    SECTION 2: PREPARING BACTERIOLOGICAL MEDIA IN A LABORATORY FACILITY Membrane Lauryl Sulfate Broth: For 50 tests, dissolve 7.62g of Membrane Lauryl Sulfate Broth (one sachet) in 100mL deionised water. The broth is supplied in a pre-weighed sterile sachet, with indicating silica gel that will turn from orange to green, to indicate moisture penetration.

    SECTION 3: PREPARING BACTERIOLOGICAL MEDIA IN THE FIELD Membrane Lauryl Sulfate Broth: For 50 tests, dissolve 7.62g of Membrane Lauryl Sulfate Broth (one sachet) in 100mL deionised water. The broth is supplied in a pre-weighed sterile sachet, with indicating silica gel that will turn from orange to green, to indicate moisture penetration.

  • Page 31: Section 4: Sampling

    SECTION 4: SAMPLING Rivers and streams Take the sample as near as possible to the fastest flow – this will typically be found towards the centre of the body of water. Avoid taking samples from too close to the bank, where the water may be still and unrepresentative.
  • Page 32 Heat Disinfection of Tap This method is applicable for metal taps, but not for any plastic taps or taps with non- removable anti-splash devices. Turn off the tap fully, and flame the closed tap with a small Propane or Butane burner; cease flaming if/when any steam issues from the tap.

  • Page 33: Section 5: Use Of Bacteriological Media

    SECTION 5: USE OF BACTERIOLOGICAL MEDIA If stored correctly, the dissolved media should remain stable for 6-8 weeks. However, if there are any signs of contamination e.g. yellowing, cloudiness etc., discard. Ideally, to reduce the possibility of contamination, use one bottle of media only for a 24 hour period, and use a fresh bottle on each subsequent day.

  • Page 34: Section 6: Aseptic Procedures

    SECTION 6: ASEPTIC PROCEDURES Aseptic procedures are of paramount importance during microbiological analysis, and extra care must be taken when outside the central laboratory, i.e. in the field. Everything must be kept clean and sterile, particularly on the following surfaces: Inner surface of the sampling cup Inner surface of the graduated filter funnel Filter membrane and absorbent pads...
  • Page 35 Pads are supplied sterile, in cartridges of 100. A sterile pad dispenser is supplied for depositing the pads into the petri-dishes. It is preferable to dispense pads at the central laboratory, prior to going to the sampling point; in this way, the dispenser may be kept attached to a pad cartridge and remain clean and sterile.

  • Page 36: Section 7: Processing Samples For Coliform Analysis

    SECTION 7: PROCESSING SAMPLES FOR COLIFORM ANALYSIS All samples must be incubated within 6 hours of sampling. Dispense a sterile absorbent pad into a sterile petri dish, and saturate the pad with prepared broth Loosen the graduated filter funnel, and remove from the base support. Sterilise the forceps and allow to cool.
  • Page 37 Pour the water sample into the filter funnel up to the 100 ml graduation. Connect the hand vacuum pump to the filtration unit base (ensuring the arrow is orientated to the direction of desired air flow) and pump in a controlled fashion to suck the water sample through the membrane.
  • Page 38 When all the water has been filtered, release the vacuum pump and use the sterile forceps to take the membrane from the filtration unit. Place the membrane on top of the pad, which has been previously saturated with the MLSB media.

  • Page 39: Section 8: Counting Coliforms And Recording The Result

    SECTION 8: COUNTING COLIFORMS AND RECORDING THE RESULT Note the temperature that the incubator has been set for. Following incubation, switch off the power and remove the petri dishes from the incubator. Place the petri dishes on a flat, level surface. Remove the lids and count all the yellow colonies, irrespective of size.

  • Page 40: Section 9: Selecting The Optimum Volumes For Membrane Filtration

    SECTION 9: SELECTING THE OPTIMUM VOLUMES FOR MEMBRANE FILTRATION The optimum volume of sample is that which will allow the most accurate quantification of bacterial colonies. This is achieved when the number of faecal (thermotolerant) coliform colonies on the membrane following incubation is between 20 and 200 colonies. If there are fewer than 10 colonies, then there exists the possibility of statistical error.

  • Page 42 SECTION 1: ASSEMBLY OF TURBIDITY TUBE Carefully remove the two halves of the turbidity tube from their position, in the foam recess at the front of the AquaSafe Kit. Align the two halves of the turbidity tube so that the graduations are easily visible, then push together the grey bolting mechanism and screw together using the grey waterproof connector.
  • Page 43 SECTION 2: ANALYSIS Good illumination is essential for accurate use of the turbidity tube. Look through the open end of the tube, at the black square on the base of the tube. This is the Trace2o Secchi marker. Hold the tube vertically, and slowly pour the water sample to be analysed into the tube, until the moment that the Secchi marker is no longer visible from the top of the tube.
