Seria DKL cuprinde urmatoarele modele:
- DKL 8 (8-pozitii cu eprubete de 250 ml, Ø 42 mm)
- DKL 12 (12-pozitii cu eprubete de 250/400 ml, Ø 42 mm)
- DKL 20 (20-pozitii cu eprubete de 250 ml, Ø 42 mm)
- DKL 42/26 (42-pozitii cu eprubete de 100 ml, Ø 26 mm)
Prevazute cu microprocesor de control a temperaturii blocului si cu un sistem de calibrare temperaturii automat ce asigura o repetabilitate foarte buna a analizelor.
Display grafic LCD va permite accesul la toate datele obtinute inclusiv cele 54 de programe disponibile, 24 din ele sunt configurabile si programabile de operator.
Conform cu GLP (Good Laboratoiry Practice), datele pot fi printate sau pot fi transmise la un PC.
Siguranta
Depasire temperatura setata: termostat integrat
Sonda de temperatura defecta: detectie automata / alarma vizuala
Lift in miscare (dispozitiv de ridicare / cobarire): alarma vizuala / sonora
Temperatura suprafata: semnal vizual daca depaseste 50 °C
Pentru neutralizarea fumului produs in timpul procesului de digestie, seria DLK ar trebui folosita cu o pompa de aspiratie "pompa JP" si un sistem de neutralizare a fumului (scrubber SMS); Producatorul VELP va recomanda sa utilizati pompa JP si sistemul Scrubber SMS; pentru modelul DKL 42/26 doua pompe JP sunt recomandate.
