2619407 Bacteria Tests: Hach Nitrifying Bacteria 7 pk by AquaPhoenix

BART biodetectors are excellent diagnostic tools to help identify the presence and activity of various bacteria.

Nitrifying bacteria recycle organic nitrogenous materials from ammonium (the endpoint for the decomposition of proteins) to nitrates. In water, aggressive nitrifiers can produce high concentrations of nitrates. Nitrates in water can be a potential health risk. Aggressive nitrifying bacteria in waters may indicate the latter stages of aerobic degradation of nitrogen-rich organic matter. This can indicate that the water may have been polluted by nitrogen-rich organics from sources such as compromised septic tanks, sewage systems, industrial and hazardous waste sites and is undergoing an aerobic form of degradation.

• Simple yet effective method for monitoring the population size and/or activity of specific groups of bacteria
• Easy to use, requiring no elaborate or costly equipment and no specialized training
• Effective and affordable tests are easy to interpret and can be performed at room temperature in virtually any environment

S350CDHF pH Sensor, Flat, Polymer, 12mm, HF by Sensorex

The specification sheet serves as an addendum to the pH LabSpecs sheet and covers all lab pH electrodes suitable for use in hydrofluoric acid.

Specifications differences for use in hydrofluoric acid (HF) are shown in SPECIFICATIONS section below. Please note 2 major differences as compared to standard electrodes. First, pH range is 0-12 not 0-14. Second, the temperature range is 0-50 deg C.

This series of electrodes are compatible with any lab or portable pH meter. Calibration of these electrodes is as normal with any standard pH electrode using standard pH buffer solutions.

• Resist attack and etching from HF (up to 2% v/v)
• Resist coating and fouling
• Compatible with any pH meter
