Precise reciprocal shaking baths controled by microprocessor and with refrigeration. Unitronic reciprocating shaking bath linear: temperature range from ambient +5 ºC to 99,9 ºC. (Stability ±0,05 °C, homogeneity ±0,1 °C, set temp. error ±1 °C, resolution 0,1 ºC). Unitronic reciprocating shaking bath C linear: temperature range from 0 ºC to 99,9 ºC. (Stability ±0,05 °C, homogeneity ±0,1 °C, set temp. error ±1 °C, resolution 0,1 ºC). Features: - Linear motion sliding tray from 10 to 100 oscillations per minute, with a variable stroke length of 32 or 46mm. - Digital display and selection of temperature, oscillations and time. - Controllable time from 1 minute to 99 hours 59 minutes. - Temperature sensor: thermo-resistant Pt100. - Rack frame support made of AISI 304 stainless steel incorporated in the tank that can accommodate a selection of flasks and racks. - Internal tank made of AISI 310 stainless steel with an external case of AISI 304 stainless steel. - Built in drain tap.
