The HPLC pumps in the WellChrom family, in particular the K-120, K-501, and K-1001, all feature the same mechanical drive. Thus, all pumps can be equipped with the same type of pump head.
 |
WellChrom HPLC Pump K - 1001 This top-of-the-line HPLC pump features electronic residual pulsation
suppression. The pump also contains the complete logistics for gradient
operation and can be upgraded (without using a PC) with the Knauer Solvent Organizer
(A4012, A4013) to form a quaternary low pressure gradient system.
Alternatively multiple K-1001 pumps can be combined for high pressure
gradients. |
