About series Digtor 21 C General specifications User friendliness • Digtor 21 C-U: Centrifuge for oil without heating for 4 tubes of 8 “. • Digtor 21 C: Centrifuge for oil with heating for 4 tubes 8”. • Digtor 21 C-8: Centrifuge for oil with heating for 8 tubes of 8”. These three centrifuges include the all standards on safety and also include the pre-installation for GRS (Gas Release System) for aerosols’ extraction formed along centrifugation, that could affect to the user and lab environment. A complete & safety solution for oil and bio fuel labs. - TFT touch screen easy to read and values selection (RPM on steps of 100, RCF on steps of 10xg), time, temperature (1°C steps) and acceleration/deceleration (1 second steps). - The screen which indicates the status can be seen from more than 3m. - Rotor and adapters list on memory. Automatic rotor recognition - Real values on screen of RCF (x g) based on accessories configuration. - Timer count up/down, from 0 or at “set RPM/RCF” for test reproducibility. - Progressive acceleration and braking selectable by operator up to 175 ramps. - Microprocessor controlled. Automatic lid latch lock. - Option: free or locked adjustment of RPM/RCF along the run. - Program data protection through password selectable. - Device and accessories specially designed for oil applications. Centrifuges on oil lab can be used for several applications as sediment & water on oils, fuel oils and middle distillate fuels, precipitation on lubricating oils, characterization of bio fuels… Ortoalresa has expanded its Series Digtor 21 C, thinking about all user, now formed by three centrifuges: - Induction motor maintenance free. - Max. speed 3.000 RPM/2.425 RCF (on steps 100 RPM/ 10 xg) - Quiet: noise level < 60 dB. - 15 memories + pre-heating program: it allows warm the chamber to test temperature before spin the sample (except Digtor 21 C-U with 16 memories). - Short spin key with speed adjustable. - Bio fuel compatible. - Proper for conical ( 6 or 8 “), trace sediment and pear or 12,5 ml. - Optional Gas Release System: all devices include pre-installation. - Isolated avoiding heat lost. Overheating protection. - Lid locking and holding and lid dropping protection. - Imbalance switch off. - Chamber of centrifugation in stainless steel. - Viewing and calibration port in the lid. - Messages about progress on TFT. - Guard ring between the chamber of centrifugation and the housing. - Tubes on upright on rest. Digtor 21 C–U is the unheated version of Serie Digtor 21C, its provided of several memories which allow the user to store up to 16 programs according different centrifugation parameters following several standards. Digtor 21 C has been equipped with accessories, rotors RT 239 and RT 220 for run 6 and 8 inches, pear shaped tubes, traces and 12,5 ml tubes, all of them specially designed for oil applications, so they are easy to clean, made in high resistance materials, allow a quick identification of samples on the rotor position. Digtor 21 C-8 is has the highest capacity of Serie Digtor 21C, it can fit up to 8 tubes of 8 inches at once. Its provided of several memories which allow the user to introduce different programs according different centrifugation parameters following different standards. The centrifuge is provided of 15 memories which allow the user to introduce programs with selectable centrifugation parameters following different standards. It’s provided of a pre-heating program which allows the operator a constant temperature along the run.
