\"\"Climate chamber,<\/strong> Snijders Scientific, The Netherlands<\/strong><\/p>\n

The climate chamber is designed to be used for a wide range of research applications like seed germination, protoplasm cultivation, tissue culture, plant growth, Arabidopsis tests, celular division and many other within life sciences with the possibility to imitate the natural environmental conditions.<\/p>\n

With a total volume of 432 liters, as well as a usable area\/shelf of 0.36 m2\u00a0<\/sup>, the chamber allows to use of an increased number of experimental replicates. The parameters that can be configured are: temperature (between +5 and +40\u00b0C), light intensity (between 0 and 10.000 Lx), humidity (between 5 and 100%). The cycle programming allows experimental standardization; up to 50 programs, as well as up to 99 segments\/program.<\/p>\n

\"\"<\/p>\n

The system allows the analysis of the organisms’ development phenotypic parameters in non-destructive conditions. This process is possible by using video and IR sensors placed above the item.\u00a0Also, a double lighting system (top, back) ensures the necessary\u00a0conditions for performing analyzes. Captures are made at a frame rate of 3.75 – 7.5 fps, allowing real-time observations. The categories of organisms that can be traced are varied; from microorganisms (bacteria, fungi) grown in Petri dishes to higher plant organisms (plants) grown in large containers. In these organisms, different processes can be quantified, such as the accumulation of biomass or the evolution of the leaf surface.<\/p>\n

Kjeldahl VELP System for the determination of total nitrogen and protein<\/strong><\/p>\n

\"\"The system consists of three complementary units for the determination of total nitrogen content from\u00a0mineral, microbial, vegetable or animal sources, having the ability to use liquid or solid samples.\u00a0The DK6 Velp Scientifica digestion u<\/span>nit co<\/span>nsists of an <\/span>electronically controlled 6-station aluminum block. The temperature of th<\/span>e block can be <\/span>adju<\/span>sted between<\/span> 45-450\u00b0C, through 20 programs and 4\u00a0 temperature and time ramps. The fume neutralization system (SMS scrubber) coupled with the water recirculation pump (JP) ensures the condensation and neutralization of fumes from the digestion process. <\/span>The UDK 139 Semi-Automatic Kjeldahl Distillation Unit allows a rapid distillation of the digested solutions. <\/span>The unit allows the scheduling of distillation time, automatic addition of sodium hydroxide and water, also the emptying of the tube. <\/span>The degree of nitrogen recovery is over 99.5%. The distillation rate is 35-40 ml\/min.<\/span><\/p>\n
