HPLC columns, Acclaim™ mixed-mode WAX-1

Catalog Number: (HYPE064985)
Supplier: Thermo Fisher Scientific
Supplier Article Number:: 064985
Description: These columns result in a multimode separation mechanism including hydrophobic, anion-exchange and cation-exclusion interactions. Consequently, retention of basic, neutral and acidic molecules can be either independently or concurrently adjusted by changing ionic strength, pH and organic solvent content in the mobile phase.

Sodium chloride ≥99.5%, white crystalline powder for molecular biology

Supplier: MP Biomedicals
Description: Sodium chloride is a commonly used chemical which is found widely in nature. It is considered to be an essential nutrient. Excess amounts of sodium chloride can destroy electrolyte balance and cause death in most animals, including humans.
Sodium chloride is used in a wide variety of biochemical applications, including intravenous fluids (normal saline is 0.9% w/v in water 10), density gradients 3,6, a diluent to increase ionic strength in buffers or culture media and in salt-out procedures in the isolation of DNA. It has also been used in high concentrations for preservation of foods since bacteria cannot grow in high salt conditions. A salt-ice mixture in the ratio of approximately 33 g sodium chloride to 100 g ice (at -1°C) will drop in temperature to as low as -21°C, depending on the rate of stirring and the size of the ice chunks.

VWR® PerfectBlue Maxi ExW 'Revolution', Wide format gel system

Catalog Number: (VWRI700-0912)
Supplier: VWR Collection
Description: The Maxi ExW 'Revolution' offers built-in buffer recirculation - without the need for pumps or additional tubing. The Maxi ExW 'Revolution' offers the same high throughput, rapid separation as the Maxi ExW model but, with the position of the cathode and a rising tube, the system uses hydrogen bubbles to slowly mix the buffer. This system thereby avoids the build-up of pH or ionic gradients for electrophoresis of maximum quality and stability.

VWR® PerfectBlue Mini L Revolution, Gel System

Catalog Number: (VWRI700-0799)
Supplier: VWR Collection
Description: The 'Revolution' series includes a buffer circulation system, powered by the electrodes themselves. Hydrogen bubbles produced at the cathode pass up a diagonally positioned pipe connected to the two sides of the tank producing a gentle circulation of the buffer. The result is no pH and ionic gradient – without need of mechanical pumps.

VWR® PerfectBlue Maxi M 'Revolution', Gel system

Catalog Number: (VWRI700-0909)
Supplier: VWR Collection
Description: Based on the Maxi M model, the Maxi M 'Revolution' offers a built-in buffer circulation system, powered by the system’s electrodes. At the cathode, hydrogen bubbles are produced and pass up a diagonally positioned pipe connected to the two sides of the tank to produce a gentle and continual circulation of the buffer. The system nulls any pH and ionic gradient – without the fuss of mechanical pumps. The system offers 6 comb positions enabling the gel to be partitioned into 2, 3 or 4 areas. In addition, the system can accommodate any of the 23 standard and microtitre comb designs described for the Maxi M model.
