1. Overview of glass capillary tubesA glass capillary tube is a slender, hollow, tiny glass tube. Glass capillary tubes have a characteristic called the capillary effect, that is, in a tiny tube, the surface tension of a liquid or gas will cause it to form a curved surface inside. Glass...
The manual capper allows for the easy and secure removal of aluminum caps with just one squeeze. The adjustable manual capper provides an adjustable stop on the handle, ensuring consistent tightness with each capping. The depth of the jaws can be changed by adjusting the screws inside the metal jaws....
Set parameters and place the sample. Set temperatures for "Sample," "Valve Box," and "Tubing" to 50 degrees Celsius, 130 degrees Celsius, and 140 degrees Celsius, respectively. Once the temperatures stabilize, introduce the sample, wait for 30 minutes for equilibrium, and proceed with the following steps. Pre-sample purging. Set the purging...
