Linear alkyl benzene sulfonic acids are one of the most common precursors for the surfactant industry. They are typically neutralized and added to liquid dish formulations or converted to a powder for laundry detergents. The acids are generally made by reacting sulfur trioxide (SO3) with linear alkyl benzene (LAB). The acid is digested and stabilized with a small water addition. The composition is typically: The composition (and acid color) will vary depending on the molar ratio of SO3 to LAB as well as the digestion conditions. The unsulfonated matter (UM) conventionally refers to the total organic nonionics after neutralization. Products & Services
Measuring microscopes are used by toolmakers for measuring the properties of tools. These microscopes are often used for dimensional measurement with lower magnifying powers to allow for brighter, sharper images combined with a wide field of view.
Linear slides are simple linear motion devices composed of a stationary base and a moving carriage. Linear stages are slides with a drive mechanism that provide controlled, precise positioning along a linear axis.
Surface tension measuring instruments measure fluid surface tension, a tangential force that keeps a fluid together at the air/fluid interface. Surface tension is a direct indicator of the quality of any chemical and any formulation.
Linear motors generate force only in the direction of travel. They are capable of extremely high speeds, quick acceleration, and accurate positioning.
Linear bearings are used in applications where a component needs to be moved along a straight line with high accuracy.
