Product description of Gastec Short-term quick-measuring detector tubes
As a leading global brand in gas detection and measuring, GASTEC products are highly regarded in many industries and customers all over the world.
GASTEC gas detector tubes are thin glass tubes with calibration scales printed on them so you can directly read concentrations of the substances (gases and vapours) to be measured. Each tube contains a particulate matrix (e.g. silica gel, alumina) which binds carefully selected and highly stable detection reagents that are especially sensitive to the target substance in order to produce a distinct layer of colour change. The tubes are hermetically sealed at both ends.

Guar gum is a fiber from the seed of the guar plant.
Guar gum is used as a laxative. It is also used for treating diarrhea, irritable bowel syndrome (IBS), obesity, and diabetes; for reducing cholesterol; and for preventing “hardening of the arteries” (atherosclerosis).
In foods and beverages, guar gum is used as a thickening, stabilizing, suspending, and binding agent.
In manufacturing, guar gum is used as a binding agent in tablets, and as a thickening agent in lotions and creams.
How does it work?
Guar gum is a fiber that normalizes the moisture content of the stool, absorbing excess liquid in diarrhea, and softening the stool in constipation. It also might help decrease the amount of cholesterol and glucose that is absorbed in the stomach and intestines.
There is some interest in using guar gum for weight loss because it expands in the intestine, causing a sense of fullness. This may decrease appetite.
USES:
Diarrhea. Adding guar gum to the tube feeding formula given to critical care patients may shorten episodes of diarrhea from about 30 days to about 8 days.
High cholesterol. Taking guar gum seems to lower cholesterol levels in people with high cholesterol. Guar gum and pectin, taken with small amounts of insoluble fiber, also lower total and “bad” low-density lipoprotein (LDL) cholesterol, but don't affect “good” high-density lipoprotein (HDL) cholesterol or other blood fats called triglycerides.
Diabetes. Taking guar gum with meals seems to lower blood sugar after meals in people with diabetes. By slowing stomach emptying, guar gum may also lessen after-meal drops in blood pressure that occur frequently in people with diabetes.
Constipation.
Irritable bowel syndrome (IBS).
