We're having some problems with our 1260 Infinity II Vialsampler (G7129A). The temperature of the sample compartment is set to 4°C, but the actual temperature is always around 10 - 12°C. When running the sampler cooler function test, it's a pass. The drainage of the condense water works fine and there is enough space for ventilation at the back of the instrument.The temperature in the lab is around 22°C. In June, the cooler thermostat was already replaced by another one, but the problem keeps on coming back...
