Compact column switching module with dual 6-port valves for UHPLC systems.
The AZURA Assistant ASM 2.1L by Knauer is a highly efficient and compact column switching module designed for integration with UHPLC systems. It features two 6-port multi-position valves capable of switching between up to 6 columns, enhancing the flexibility and functionality of the analytical setup. Each component of this robust module can be seamlessly operated via software, ensuring precise control and swift adjustments.
Key features of this module include its status as the most compact column switching and buffer selection unit available for UHPLC systems. It is equipped with two 6-port multi-position valves made from high-quality stainless steel, providing durability and reliable performance. The module's dimensions are 361 x 158.2 x 523 mm (W x H x D), and it supports a power supply range of 100 – 240V at 50 – 60 Hz with a maximum consumption of 100 W.

The valve heads are constructed of stainless steel, paired with 1/16 capillary connections, and the device maintains a maximum pressure stability of up to 1000 bar.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
