Stanje: rabljeno, Ta ponudba je za eno izmed treh laboratorijskih tehtnic Sartorius Practum 513-1S. Naprava je v popolnoma delujočem stanju in pripravljena za takojšnjo uporabo. Serijo Practum podjetje Sartorius opisuje kot »najboljše razmerje med ceno in zmogljivostjo, brez kompromisov pri točnosti in zanesljivosti.« Model 513-1S je ena izmed različic z višjo nosilnostjo v seriji Practum, saj omogoča tehtanje do 510 g s točnostjo/ločljivostjo 0,001 g (±1 mg) pri tej zmogljivosti. Tehtnica uporablja značilne lastnosti linije Practum: robustno ohišje (osnova iz tlačno litega aluminija in ohišje iz ABS plastike) ter tehnologijo, zasnovano za standardne aplikacije. Povezljivost: opremljena je z Mini-USB vmesnikom za izpis podatkov na računalnik ali kompatibilni tiskalnik. Podprta je možnost tehtanja pod tehtnico (t.i. weigh-below hook), na primer za obešanje uteži pod tehtnico. Sprednja libela in nastavljive nogice omogočajo enostavno niveliranje, kar izboljšuje natančnost in ponovljivost tehtanja. Vgrajena je mehanska zaščita pred preobremenitvijo, ki zagotavlja večjo vzdržljivost. Practum 513-1S je zelo primerna za standardna analitska in precizna tehtanja v laboratorijih, kjer potrebujete tehtanje do približno 510 g z ločljivostjo 1 mg. Tipične uporabe: priprava formulacij, splošno tehtanje vzorcev, kontrola kakovosti, določanje gostote in rutinska laboratorijska opravila. Dokumentacija za širšo serijo omenja načine, kot so štetje, odstotkovno tehtanje, povprečenje in tehtanje v nestabilnih pogojih. Zaradi svoje ločljivosti in zmogljivosti je tehtnica odlična izbira, kadar ne potrebujete ultrafine mikrogramske ločljivosti, ampak večjo tehtalno zmogljivost z miligramsko natančnostjo.
