Description: The CP-Chirasil-Dex CB phase consists of cyclodextrin directly bonded to dimethylpolysiloxane. This bond prevents the cyclodextrin from migrating to different locations in the surface film, delivering homogeneous enantioselectivity throughout the phase.

Description: CP-Al₂O₃/Na₂SO₄ is an aluminum oxide PLOT column that offers high selectivity for separating ppm levels of C₁to C₅ hydrocarbons in a main stream of C₁ to C₅ hydrocarbons. The Na₂SO₄ deactivation salt provides a polar Al₂O₃ surface, so that unsaturated compounds such as ethylene and acetylene are retained longer. These columns analyse more compounds in a single run than packed columns, while still delivering higher resolution and faster analysis times. When compared to liquid stationary phases, CP-Al₂O₃ provides increased selectivity and allows all C₁ to C₅ hydrocarbon isomers to be separated. CP-Al₂O₃ operates without the need for sub-ambient cooling.

Description: CORIO™ CP refrigerated/heating circulator combinations with stainless steel bath tanks for internal or external temperature applications from –50 to +200 °C.

Fournisseur: Thermo Fisher Scientific

Description: Hypersil™ CPS (cyano) phases offer different selectivity than Hypersil™ Silica and APS-2. Cyano columns equilibrate rapidly and are not deactivated by small quantities of water. When used as a reversed phase material, cyano selectivity complements the alkyl chain bonded phases, but with lower hydrophobicity. Hypersil™ CPS-2 is the endcapped version.

Fournisseur: Avantor Fluid Handling

Description: Capable of pumping fluids with viscosities up to 10,000 cps.

Fournisseur: JULABO GmbH

Description: The powerful and robust CORIO™ laboratory circulators provide the exact temperature, absolute precision, and a wide working temperature range. The CORIO™ CP model is an advanced unit with professional technology for demanding applications and can be used for temperature control of internal or external applications due to the powerful and infinitely adjustable pressure pump. The jet nozzle allows continuous adjustment of the pump stream in the system. These heating circulators are optimised for external temperature applications in combination with jacketed reactors, distillation apparatus, mini-plant applications, photometers, refractometers and can also be used for internal temperature applications of samples and small objects.

Description: Dihydrorhodamine 123 is the reduced form of rhodamine 123, which is a commonly used fluorescent mitochondrial dye. It is non-fluorescent, but it readily enters most of the cells and is oxidized by oxidative species or by cellular redox systems to the fluorescent rhodamine 123 that accumulates in mitochondrial membranes. It is useful for detecting reactive oxygen species including superoxide (in the presence of peroxidase or cytochrome c) and peroxynitrite. Dihydrorhodamine 123 dihydrochloride is functionally equivalent to dihydrorhodamine 123 but with increased stability toward air oxidation and light during storage. Dihydroethidium (also called hydroethidium) is the chemically reduced form of the commonly used DNA dye ethidium bromide. The probe is useful to detect oxidative activities in viable cells, including respiratory burst in phagocytes. Dihydroethidium itself has blue fluorescence (355/420 nm) in cells, while the oxidized form ethidium has red fluorescence (518/605 nm) upon DNA intercalation. H2DCFDA (2′,7′-Dichlorodihydrofluorescein diacetate) is a useful fluorogenic reagent to detect reactive oxygen intermediates in cells. On oxidation, H2DCFDA becomes the highly green fluorescent 2′,7′-dichlorofluorescein, 504/529 nm (end product).
