Journal of Environmental Science and Health, Part A - Toxic / Hazardous Substances. In this combination of persistent questions, and new horizons, it is clear that the diatoms remain as fascinating and intriguing today as they were when Von Leeuwenhoek first spied them over 300 years ago. Canadian Journal of Fisheries and Aquatic Sciences 65(6): 1206-1216. The topics address age-old questions, and explore new and emerging areas of research. This report has been produced as part of the ECETOC Joint Assessment of Commodity.
The Diatom World brings together many of the experts in the world of diatom research, who summarize important topics on diatom classification, biology, genomics research, and a broad spectrum of ecological studies, and present new data in these areas. The water bath eliminates the need for the drum tempering or pre soak and maintains the working temperature of chemical solutions simply and conveniently. Because the literature on diatoms is published in a diverse set of journals under many different disciplines, it is hard for people to track down the diverse array of cutting edge research results on the group. They are also being investigated as a source of renewable biofuels.
They are important players in a wide range of ecosystems, freshwater, brackish and marine. Tanks cant even hold so much liquid when put in working position on the processor, and 'inexpensive' paper processors would not have the power to in-length rotate a tank filled for film-developing if designed solely for paper processing (typical 0.7 litre chemistry for film vs.Diatoms are fascinating algae, whose relevance today is greater than perhaps ever before. When using it for film-processing using roll-film/35mm film reels, you need the tank to be about 1/3 filled with chemistry to submerge the spooled film. You can make one with an aquarium heater and a 15-20 gallon Rubbermaid tote or picnic cooler from Wal-Mart.Happy Processing! Being a rotating-drum print processor, it's to expect that it is designed for being used with wery little chemistry in the drum (as the paper is mounted very close to the inner walls). Paul, The only difference between a 'print' and 'film' rotary tube processor is how the film or paper is mounted in the drum.From the looks of the picture, it appears to be OK for film processing, with the following caveats: Make sure it's 'light-tight' enough Make sure the temperature control is tight enough for C41 and (especially) E6 You'll need an extra tempering tank to hold the chemicals at 100 degrees F for color film processing.
