General description
The HPLC pump K–120 is aspecially designed as a simple low
price HPLC pump. It features a double-piston construction to
deliver solvent flows in a wide range with high consistancy and low
pulsation.
The HPLC pump K-120 is delivered with the new inert pump heads
with ceramic inlays. Two different pump heads are available:
• Analytical pump head (0.001 – 9.999 ml/min),
• Preparative pump head (0.01 – 50 ml/min).
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 K–1001. 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
Pump heads can be interchanged by loosening only four screws.
Experienced users can disassemble the heads for simple
maintenance tasks like cleaning, changing piston seals etc.
The easy-to-learn use and control of the HPLC pump K–120
proceeds via keys which are clear by the first glance. The pump is
especially useful for routine and batch analyses as well as for
education purposes.
