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...

Organic Microporous Membrane: Organic microporous membranes are made of organic polymers and can be produced with different pore sizes and molecular weights through various manufacturing methods. Common materials for organic microporous membranes include polyamide, polypropylene, and polysulfone. These membranes exhibit high filtration efficiency, good mechanical strength, and strong corrosion resistance....

The sterile microporous membrane is a filtration material made of high-molecular-weight chemical compounds, featuring a micro-porous structure with uniform pore distribution and high porosity, ensuring no medium detachment. It is primarily used for filtering aqueous solutions, often referred to as water system membranes. This type of membrane is non-toxic, hygienic,...
