There are two techniques for sampling viscous fluids. TECHNIQUE 1 1. Measure a 1mL sample using a sterile graduated cylinder. 2. Either pipette or carefully pour (using aseptic technique) the sample onto the paddle. Tilt [...]
No, you need to "swab" the agar surface with the sample. Growth should include HPC (heterotrophic plate counts), as well as coliform counts.
Yes. Nutrient-TTC (NUT), Tryptic Soy (TSA), and MacConkey (MAC) agars can all be used for marine waters. Testing is essentially identical as for freshwater.
If you are incubating at room temperature, we recommend an incubation period of 36 hours. If you are incubating at 86-90 degrees Fahrenheit (30 degrees Celsius), we recommend an incubation period of 24 hours. It [...]
No, the Microslide is not acceptable to use.
Although you should determine what is an acceptable level of bacteria for your unique system, a general guide would be less than 105-106 CFU/ml for cooling water and less than 106-107 CFU/ml for metalworking fluid.
The Nutrient-TTC agar color is normally light yellow when the agar is cast. After testing, during the incubation phase, the agar may change to a light green color. This color change is a result of [...]
The print on a Microslide vial is as follows: XXX/XXX BBE: YY-MM-DD XXXXXX. Where XXX/XXX is the media on side one /side two of the paddle, BBE is the expiration date, and the last set [...]
The shelf-life of Microslides is 6-9 months if properly stored. Store out of direct sunlight at room temperature (do no refrigerate).
No. Microslides can be set out at room temperature, or placed in a warm area such as the top of a refrigerator to "incubate". Growth will still develop if Microslides are not incubated, it will [...]
