The HI931 and HI932 titrators deliver incredible results and speed for increased productivity The HI931 titrator is supplied with one analog board, propeller stirrer with stand The HI932 titrator is supplied with two analog boards, propeller stirrer with stand Titrate for a variety of measurements including acids, bases, redox and selective ions No additional programming upgrades to purchase, you can start measuring right away
THIS new generation of titrator features a 50% smaller footprint for maximum use of your lab space. The sealed body is precision-engineered to resist spills and dust and a high-contrast display shows you everything you need to know during testing. With an angled electrode holder and removable stirrer, smaller volume titrations are now seamless.
Not only can your titrator hold more electrodes and tubes, but it is also easier than ever to reposition your electrode holder using a newly designed press-torelease button and rotating disk. Our unmatched 40 000-step dosing pump is capable of dosing extremely small volumes of titrant to help you achieve a very precise endpoint for greater consistency. There is no other like it. With the second analog board, a burette or peristaltic pump can be added for more power, more usability and more versatility. Our exchangeable Clip Lock burette system helps you conveniently separate and switch between your reagents, so you don’t have to worry about cross-contamination. A dynamic dosing algorithm allows for timely and accurate titration results by providing larger doses near the beginning of a titration and smaller, more precise doses near the titration endpoint.

Custom-built growth tables THE growth tables are built to be used in a controlled environment, like an indoor growth room with controlled humidity and temperature. We do not supply the temperature or humidity control or automatic watering, but the temperature can be controlled using a standard wallmounted air conditioner. The growth tables are usually 1m long by 0.5m wide and have three usable shelves 500mm high, with 3m x 1m LED growth lamps shining down onto each usable shelf. The latest growth tables that we are constructing have two usable shelves and each are adjustable from 500mm to 800mm high. The LED grow lights are 800mm strips with a 3:1 ratio of three red and one blue LED spaced at 50/50, which is 50 LEDs per meter. These LED strips are waterproof and are fitted inside an extrusion bracket with a clear cover for extra protection. All the tables are interchangeable and each bank of three shelves is served by a 10A 12V transformer with overload and short-circuit cut-out protection. Each transformer has its own trip-switch for added protection, and it also allows the user to turn on and off each bank of tables
