( Brand: Waters ), ( Model: WAT270986 ), ( Part Type: Tube )
The Waters 2690 GPC Tube (Item number: WIT270986) is a high-quality, premium product designed for use in gel permeation chromatography (GPC) applications. This tube is manufactured by Waters Corporation, a renowned name in the field of analytical chemistry and laboratory science.
The tube is made of high-density polyethylene (HDPE), a material known for its chemical resistance and durability. This ensures that the tube can withstand the harsh conditions often found in laboratory environments, without leaching or degrading over time. The HDPE material is also resistant to solvents commonly used in GPC, such as water, methanol, and acetonitrile.
The Waters 2690 GPC Tube has a nominal inner diameter of 0.25 inches and a length of 12 inches. This size is suitable for a wide range of GPC applications, including the separation of polymers, proteins, and other large molecules. The tube is also available in other sizes to meet different experimental requirements.
The surface of the tube is treated with a hydrophilic coating to minimize adsorption of analytes, thereby improving the resolution and efficiency of the chromatographic separation. The coating is also designed to minimize non-specific binding, ensuring that the true molecular weight distribution of the sample is accurately determined.
The Waters 2690 GPC Tube is designed to be compatible with most GPC systems, including those from Waters Corporation and other major manufacturers. The tube is delivered in a sterile condition, ensuring that it is ready for use in laboratory applications without the need for additional cleaning or sterilization.
In conclusion, the Waters 2690 GPC Tube is a high-quality, reliable, and versatile product for GPC applications. Its HDPE construction, hydrophilic coating, and compatibility with various GPC systems make it an excellent choice for laboratory professionals seeking a reliable and consistent chromatographic separation.
