Features at a glance

The density meters DS7000 work according to the frequency oscillator principle and
are very easy to use.
The density meter DS7000 can be operated as follows:
• with drying unit DS7050 (for manual filling)
• with drying unit DS7050 and peristaltic pump DS7070
• with drying unit DS7060 and peristaltic pump DS7070
The peristaltic pump DS7070 with drying unit (DS7050/DS7060) enables semi-automatic
sample filling with subsequent cleaning and drying of the frequency oscillator.
If drying unit DS7060 is connected, unplugging and plugging in is not necessary for
drying the frequency oscillator with the 3/2 way butterfly valve.
The control and entry of parameters is effected via the density meter.
The flow rate can be adjusted directly using the variable rotation speed. A time-controlled
start/stop mode enables the dosage of fixed volumes.
The DS7000 makes use of frequency oscillators consisting of glass - inspection of
the bubble-free filled frequency oscillator is possible through a window.
The sample to be measured is filled into the measurement chamber using a Luer
disposable syringe or with the help of the peristaltic pump and is tempered with the
internal Peltier temperature control.
The measurement is started by pressing the button, the density meter waits until the
sample has reached the desired temperature and automatically starts the sample
measurement.
The results are shown on the display and are saved in a data bank.
If required, the results can be printed and exported.
The density meter is intended for use in FDA-regulated areas through GLP compliance,
built-in user administration and complete network capability for simple integration into
the laboratory environment and connection to a LIMS.
All data (measured values, parameters and methods) are organised in an SQL database.
Selected results can be exported in Excel/HTML format onto a USB stick and a firmware
update can be carried out easily using a
USB stick.
