    HN-05 Kjeldahl Nitrogen Determination Auto Distiller

    Controlled by microcomputer, large LCD: working status of instrument, operating procedure and testprogress
    Steam transmitter High/middle/low/empty water levels, steam pressure, temperature.
    Monitoring the condensing tube temperature, in case the temperature is over 40℃, the alarm will be on.
    Middle, low, empty and high liquid levels of water, boric acid, sodium hydroxide, the alarm will be on when liquid level runs empty.
    he alarm will set off when waste liquid level is full
    One key touch sets work procedure of the instrument:
    User can set steam pressure and temperature of operation and standby mode, when the instrument is at standby mode, stop supplying water is counted into water collecting time (for the purpose of water savingconfigurations)
    Touch pad, upon pressed touch pad, the certain quantity of water will automatically come in, together with boric acid and sodium hydroxide (Precision: ml, accuracy±1.5%, subject to water)
    One key touchmicrocomputer will automatically suggest fill up over 50% sodium hydroxide according to the residuals in the digestive tube.
    One key touch: sodium hydroxide can be added in several times, and renew steam.
    The pressure and temperature of instrument on operating and standby modes, together with theduration of stop water supplying from standby to rest (for the purpose of water saving, optional), recovery rate is more than 99%.
    One key touch: It’s allowed to activate alarm by pressing one key only while setting response time, distillation time, and waste liquid siphoning time, in addition, it may print operation materials, (the operation procedure may be finished by just pressing one key), recovery rate is more than 99%.
    Power 2200W
    distillation speed 30-40ml/ min
    Principal part of shell is made of stainless steel
    The key parts are covered by ABS plastic for protection, and resistance to hot alkali
    2) Performance detailed explanation:
    240128 Lattice big LCD with optional display of Chinese or English. . Real-time display unit status, operation procedure, test progress, liquid level and temperature
    Display unit status: steam transmitter has liquid level / pressure / temperature. The temperature of condenser tube, and various liquid levels.
    Operation procedure: access to the reaction standby section after filling up all the reagents in order, then distill, and alarm is over; waste liquidsiphoning, finish the alarm; standby stage.
    Test progress: the reaction time after adding NaOH; time remaining of distillation upon starting; waste liquid siphoning time aftersiphoning.
    Accessing to dormant state after stop working for 10 minutes (steam transmitter temperature is less than 80 ℃), with very fast speed in restart
    Applying Snake-like stainless heating pipes, which features fast heating speed and long life span. The heating power: 2100W above.
    Steam transmitter pressure could be set, 30-40mL/min condensing reclaimed liquid
    Built-in microcomputer, operator can set according to the demands:
    Steam pressure: it had been set when leaving factory, generally, no necessary to alter it; with automatic protection to overpressure.
    Steam temperature: within 130℃, modify according to measured requirement.
    Residual volume of vitriol oil: 9999.9mL(the previous one is maximum setup, self configuration is permitted on demand), the computer will advice to add amount of NaOH exceeding 50% of the volume.
    Automatic added volume of NaOH: 9999.9mL, the times of adding could be set. (The previous one is maximum setup, self configuration is permitted on demand)
    Response time: 99 minutes and 59 seconds, kjeldahl nitrogen determination could be o” for certain seconds. (the previous one is maximum setup, self configuration is permitted on demand), the function is primarily used for organic chemistry reaction like measurement of acidum citricum.
    Distillation time: 99 minutes and 59 seconds, in common cases, in 2-5 minutes, (the previous one is maximum setup, self configuration is permitted on demand)
    Reclaimed liquid (pumping waste liquid) Time: 99 minutes and 59 seconds, generally, less than 50 seconds. (The previous one is maximum setup, self configuration is permitted on demand)
    Imported built-in electronic diaphragm pump, designed for supplying water to steam transmitter.
    Imported built-in metering pump siphons NaOH, water, and H3BO3 (error of water metering is less than 1.5%)
    Built-in anti-corrosion pump will siphon waste liquid, and drain it away independently. Waste liquid could be ef
