Why Buy From Fondriest?


Hach's Total Bacteria Media Set saves time and labor costs with ready to use MPN tubes, with minimal training requirements.


In as little as 45 minutes, ToxTrak allows you to evaluate toxicity in a sample. Applicable to both drinking water and wastewater, ToxTrak measures and compares the toxicity of a sample to a baseline using either indigenous biomass or stock bacteria cultures.


Toxicity is monitored using several methods, such as growth, specific enzyme activity, bioluminescence, and respiration. These methods may require lengthy incubation times, centrifugation, solvent extraction, laborious colony counting procedures, and expensive equipment. With the ToxTrak Toxicity Test, a simple colorimetric method is used to determine the inhibitory effects of a waste stream on bacteria. With a photometer, you can monitor large numbers of samples quickly and inexpensively.


Cut costs in your laboratory by using ToxTrak to screen for potentially toxic influents and effluents. Or use it to identify dilutions for long-term bioassays. Long-term bioassays can require two to seven days to complete and are costly to perform.


ToxTrak is an inexpensive alternative that has results comparable to respirometric methods measuring dissolved oxygen consumption. ToxTrak can be used to screen influent and effluent and/or process waters. ToxTrak is also a useful tool for evaluating fluctuations in drinking water quality caused by intentional or accidental contamination.

First Environmental Monitoring System For Baltimore’s Inner Harbor

Baltimore’s Inner Harbor and the rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites and the targets of an ambitious clean-up plan. But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.

Parasite Behind Yellowstone River Fish Kill Found In Other Rivers

A parasite that caused a massive fish kill in Montana’s Yellowstone River has been found in at least seven other rivers in the state, according to the Bozeman Daily Chronicle . Scientists with the Montana Fish, Wildlife and Parks department made the find. So far, the parasite has been confirmed in the upper and lower Madison, East Gallatin, Bighorn, Stillwater, and Boulder Rivers. It had already been confirmed in the Jefferson and Shields Rivers. The microscopic parasite causes proliferative kidney disease, one of the most serious diseases to impact whitefish and trout. The effect of the disease on Yellowstone’s fish populations is exacerbated by other stressors like near-record low flows, consistent high temperatures and the disturbance caused by recreational activities.

ESPniagara Tracks Algal Toxins In Lake Erie, Protects Drinking Water

It may have taken 20 years and $20 million to develop, but Lake Erie researchers working to fight harmful algal blooms (HABs) now have a new tool to safeguard drinking water: ESPniagara. The advanced sampler has been called a “lab in a can” for its ability to sample microcystins, the most common algal toxin these days, in almost real time. The big gadget’s name is a mashup between “ESP,” for environmental sample processor, and the name of Admiral Oliver Hazard Perry’s ship during the War of 1812. “We wanted to name it something that was significant to Lake Erie,” said Tim Davis, molecular biologist and lead HABs researcher at the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Lab (NOAA GLERL) in Ann Arbor, Mich.
