ECO Silver LAUDA Immersion Thermostat

4 block dry heaters Designed for daily use in the laboratory, dry block heaters are ideal for applic (more)ations that require particular temperature stability. All units house four easily interchangeable modular blocks, with 40 options to choose from. Close contact between tube and block ensures maximum heat retention for efficient heating. Analog models: economic alternative; low temperature range: +5°C above ambient temperature to 100°C; high temperature range: 75°C to 150°C; control via two temperature adjustment knobs. Digital models: for repeatable results; from 5°C above ambient temperature to 120°C; control via touch pad controls with independent and easy to read LED displays for temperature and time display; sound alarm. - Exceptional temperature uniformity and extraordinary thermal stability. - Unique single point calibration function to ensure accurate display of actual temperature (digital models) Applications Culture incubation and activation, enzymatic reactions, immunological analyzes, melting / boiling points, isothermal incubation, nucleic acid denaturation Display LED display in digital models and knob with double adjustment and markings in analog models Operation Detachable three-wire cable and plug (included). Analog models require an external thermometer or temperature adjustment tool for the setpoint Structure Painted steel armor and support bar attachment with fixing knob Construction features Keypad control and audible alarm (digital models)

This Leitz Laborlux K Binocular Microscope was removed from a university lab where it was surplus to (more) requirements. The unit powers up and is in full working order. It is in reasonably good cosmetic condition but has some marks and scratches from where stickers had been removed. The Condenser rack and pinion is damaged with teeth missing, if it's turned up too high the knob will get stuck.
