General description
General description
Outstanding feature of the HPLC pump K-501 is its double piston technique,
which enables a high consistancy in the flow rate together with a very low
pulsation. The HPLC pump K-501 is delivered with the new inert pump heads
with ceramic inlays. Two different pump heads are available:
Analytical pump head
●
Preparative pump head
●
These heads combine the features of the older stainless steel versions with
those of the PEEK ones and replace both from now.
The new features are
Inert, biocompatible.
●
The 10 ml pump head is pressure stable up to 400 bar.
●
The 50 ml pump head is still pressure stable up to 150 bar.
●
The sealings are easily accessible due to the new splitted design.
●
Four different older pump heads can also be used with the HPLC pump K501.
These are the analogous stainless steel and PEEK versions respectively:
Analytical pump head (0,001 – 9,999 ml/min), stainless steel
●
Analytical pump head (0,001 – 9,999 ml/min), PEEK
●
Preparative pump head (0.01 – 50 ml/min), stainless steel
●
Preparative pump head (0.01 – 50 ml/min), PEEK
●
The pump heads are easy to exchange simply by loosening of only four screws.
The experienced user is able to disassemble the pump heads for cleaning
purposes or the exchange of wear and tear parts.
The easy to learn operation and control of the HPLC pump K-501 is performed
via a clear keypad and a two line display. The following functions, parameters,
and settings may be changed by a manual input:
START/STOP
●
PURGE
●
Flow rate
●
Pressure thresholds (P
●
Pump head selection (4/6 types)
●
Offset correction "measured pressure value"
●
Analog input adjustment (offset, amplification)
●
PURGE function adjustment (flow rate, check)
●
Flow rate adjustment
●
Selection of the operating mode (RS-232, analog, standalone)
●
GLP report display (total operating time, serial number)
●
(0,001 – 9,999 ml/min),
(0,01 – 50 ml/min).
