ÄKTAxpress is a liquid chromatography system intended for automated, multi steppurification processe (more)s. The system has been developed and optimized for purificationof Histidine-tagged and Glutathione S-Transferase (GST)-tagged recombinant proteins from clarified or crude cell lysates. ÄKTAxpress supports a number of purification protocols containing up to four chromatography steps, for example, affinity chromatography followed by desalting, ion exchange, and gel filtration. Protocols for purification of both low expressed proteins and well expressed proteins are included. Also protocols supporting purification of double tagged proteins and protocols that can be combined with on-column and off-line (batch) tag cleavage are provided. ÄKTAxpress provides the following features: •Automatic purification of up to four samples in a single run. •Purification protocols containing up to four chromatography steps. •Automated on-column affinity tag removal in the first step of purification protocols starting with an affinity/ion exchange chromatography step. •Purification protocols supporting purification of both well expressed and low expressed proteins, double tagged proteins and proteins that have been cleaved off-line. •Up to 50 mg of protein can be purified per sample. •Up to twelve ÄKTAxpress systems can be run in parallel, controlled from one computer (not included). Different purification protocols can be run simultaneously. •The systems can be placed next to each other or they can stand separately if preferred.

The HX7.4 H/Z scale is a device constructed on the basis of a PUE HX7 terminal and a ground-embedded (more) 4-load-cell platform, both manufactured using the AISI 304 stainless steel. The device&#39;s high protection class, IP66 / IP68, makes it suitable for use in industry. HX7.4 H/Z Comfort of operation is guaranteed thanks to a clear-cut menu, and a colour display featuring a 9-diode bar graph blinking red and green when signalling current net mass of a load in reference to the scale range or declared min and max thresholds. Housing back is equipped with hermetic communication interfaces such as RS232, RS485, USB, Ethernet, at your disposal there are also digital inputs/outputs and analogue output. This enables cooperation with external devices such as barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control and superior IT systems. With use of the bracket you can either place the indicator at any flat horizontal surface, or fix it to the wall adjusting the tilt respectively to suit your needs. The terminal&#39;s software allows carrying out processes such as weighing, parts counting, dosing, labelling, formulations and percent weighing. The terminal&#39;s system of information is based on databases: users, products, weighings, packaging, formulations, customers, ALIBI memory which guarantees stored data safety. The frame for recessing (foundation) is part of the set &ndash; you will receive it with the ordered scale.
