due to VT air flow problems with 1.7mm tubes, the VT settings have been changed – please run at 450 lph (now the default setting) with either 5mm or 1.7mm tubes. A new probe thermocouple was installed on 7/30/2018 - the VT has been tuned and the temperature reading recalibrated. Temperature correction is turned on so just input the desired sample temperature in the VT panel and the instrument will correct its temperature automatically. An info sheet with current settings is posted by the userlog. (updated 8/6/2018)
the probe has a Shaped Sample Tube Accessory for salty samples - please consider using this for samples > 150mM NaCl.
