The e-PTFE membranes are recognized as the principal tested membranes for GTR, especially Gore-Tex®. Reinforced Gore-Tex® membrane is e-PTFE reinforced with titanium. These e-PTFE membranes are available in various forms, thus they can properly maintain the space to be regenerated, and in case of exposure they are easily removed.
Jun 03, 2017 · The membrane field probe for direct N 2 O detection in a liquid consists of an aluminium rod (L = 400 mm, OD: 43 mm) with a thread fitting the dimensions of the membrane tube used previously. 6.8 m of membrane tube are coiled on the circumference of the cylinder, at each end springs prevent bending of the tube (see Fig. 3). Inside the cylinder
Membrane Microfiltration Glassware. This 47 mm filtration apparatus with fritted glass support is recommended for routine filtration of corrosive liquids and removal of particles from LC solvents. The ground joint connection eliminates phthalate contamination that can occur when using silicone or neoprene stoppers.

Mar 04, 2021 · Another way to reuse biowaste such as eggshells is to use them as crop fertilizer. They provide a very good natural source of calcium, which helps some plants grow in calcium-deficient soil, and they balance the soil pH [3,4,13,19,20,21]. Eggshells are a natural biomaterial, so they have found practical applications in various fields of medicine.
The PTFE membranes showed potential and had a longer lifetime than the PP membranes and removed up to 64% of NH 3 molecules from the condensate waste. The product formed contained a 30% concentrated ammonium sulphate salt which has a potential application as a fertilizer.

Weldable Membranes. Venting membranes made from porous PTFE can be excellently welded on plastic parts, thermally or using ultrasonic technology. Welding enables a highly durable connection between the membrane and the component, even under harshest conditions. The membranes ensure reliable venting and protect the housing against penetrating
A 30mRxi-5MS capillary column (Restek, USA) with an inner diameter of 250 mm and a film thickness of 0.25 mm was used for chromatographic separations. The GC oven was programmed from 40 (1 min hold) to 180 °C at the rate of 15 °C min −1 and then to 300 °C at the rate of 5 °C min −1 and held for 12 min.
The membranes used for MD are clearly hydrophobic and PTFE MS membrane made of PTFE, exhibiting a contact angle approaching at 140°, higher than that of PP membranes. The PP2HF membrane exhibits a water contact angle higher than that of the PP1 membrane, probably owing to the higher surface porosity.
