Important Note:
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.  The flow rate reproducibility is better than 0.1 %.
