Overview
The Hach DR 3900 is a benchtop visible spectrum (320-1100 nm) split beam spectrophotometer with over 220 pre-programmed methods optimized for laboratory water analysis. The DR3900 spectrophotometer is optimized for safe processes and accurate results daily. Control parameters like Ammonium, COD, Phosphate, Nitrate and many others are easy to test.
Simple Preparation
NTplus® vials use Dosicaps - freeze-dried reagents integrated into a sealed cap - that are easier to use than Powder Pillows or Liquid Reagents, without any risk of contamination. The boxes and vials are color-coded for fast and easy parameter and range recognition of the test needed. Step-by-step illustrated test methods are printed on the box as a quick reference and can also be called up in the instrument menu.
Comprehensive Documentation
Measurement results are documented on a detailed level with a timestamp, operator ID, absorbance reading, and calculated concentration. The 2D barcode delivers the lot number and expiry date, logged with every result. For accreditation, the certificate of analysis can be called up just by wiping the reagent box towards the RFID sensor.
Fast Execution
The Hach DR 3900 spectrophotometer automatically reads a 2D barcode on the TNTplus vial to identify the appropriate method and take the measurement. The vial spins to take 10-fold absorbance readings that will be averaged for result determination to exclude scratches and fingerprints. Instrument calibration verification and high instrument stability all combine to eliminate the need to run reagent blanks.
Customizable
With the ability to store hundreds of user-determined methods, operators are able to tailor the DR 3900 to meet the everyday needs of the facility. Optimizing and customizing the method portfolio, combined with regular software updates and Claros™ connectivity, makes the DR3900 the ultimate solution to water quality lab needs.

Poás Volcano Gives a Glimpse of Life on Mars
To get an idea of what life would be like on Mars, you don’t need to travel millions of miles away--instead, you could go to Costa Rica and visit the Poás Volcano and its crater lake, Laguna Caliente. “Collectively, the suite of alteration minerals at Poás crater and identified across Mars at relict hydrothermal sites shows strong correlation, indicating the high temperature and highly acidic geochemical processes occurring at Poás are quite relevant to understanding past hydrothermal processes on Mars,” says Justin Wang, a graduate student at the University of Colorado, Boulder. He is currently conducting research at the Laboratory for Atmospheric and Space Physics alongside his advisor, Brian Hynek. Wang is currently a master's student in aerospace engineering.

Stone Lab: Cyanobacteria Monitoring in Ohio Lakes
Microcystin, one of several toxins produced by the cyanobacteria that form harmful algal blooms (HABs), has become a popular topic of lake research as the human health impacts of HABs become better understood. Stone Lab is one of the leading groups in algal bloom research on Lake Erie and other lakes in Ohio. For more than 100 years, Stone Lab has conducted biology research and provided science education and outreach to the region. Over the years, thousands of individuals of varying ages have learned from the resources Stone Lab provides. Stone Lab’s Research Coordinator and Senior Researcher, Justin Chaffin, learned of Stone Lab while an undergraduate student at Bowling Green State University Fireland Campus.

From Assessment to Angler: Continual Research Ensures Lake Erie Remains a Beacon of Freshwater Fishing
Lake Erie is well known for its abundant recreational fishing. Anglers come from across the country to try their luck at the “walleye capital of the world” and search for other freshwater species, such as bass, perch, and steelhead trout. As one of the world’s largest freshwater fisheries, much effort is made behind the scenes to maintain fishing opportunities for visitors to enjoy year after year, efforts that often go unnoticed by the public. One of the lake's most important economic and tourism centers is the city of Sandusky, home to the Sandusky Fisheries Research Station . As part of the Ohio Division of Wildlife, the unit serves as a base for assessing fish populations and managing harvest with partner agencies from around Lake Erie.
