Syringe filters labeled CHROMAFIL Xtra PTFE, 25 mm, 0.22 µm, 100 Pcs Box
Brand: MACHEREY‑NAGEL
Origin: Germany
Inside the syringe filter polytetrafluoroethylene is used as membrane material. The hydrophobic PTFE membrane is very resistant towards all kinds of solvents as well as acids and bases. Flushing with alcohol, followed by water, makes the originally hydrophobic membrane more hydrophilic. All CHROMAFIL filters are autoclavable (121 °C and 1.1 bar for 30 min)!

Quantofix Peroxide Test Strip 100 Pcs Pack
Description
This test strip is ideal to test levels of peroxide in solutions. The easy dip-and-read procedure provides reliable results within 15 seconds
This peroxide test strip is used for many different applications. For example, in chemical laboratories, QUANTOFIX® Peroxide 100 test strips are used to check organic solvents, because peroxide containing solvents may explode when heated. Moisten the test pad with the solvent and allow it to dry. After drying, add a drop of distilled water to the test pad. If the test pad remains white, the solvent is free of peroxides and can be used safely.
Additionally, the test strips are often used to test for residual peroxide in cleaning procedures where high potency disinfectants are employed, e.g. in the dairy industry.
Additionally, QUANTOFIX® Peroxide 100 test strips are CE marked and are therefore especially suitable to be used in the healthcare environment such as hospitals, doctors offices, etc. Since the test strips can be stored at room temperature, testing with QUANTOFIX® Peroxide 100 becomes especially convenient.
QUANTOFIX® Peroxide 100 test strips are the ideal tool to test for peroxide in solutions detecting peroxide in the range of 1 – 100 ppm H2O2.
