Leverandør: Thermo Fisher Scientific

Beskrivelse: These columns offer unique selectivity for aromatic and moderately polar analytes. Suitable for complex samples where some peaks are well resolved on a phenyl phase whilst others require a conventional alkyl phase. Based on Core Enhanced Technology, they provide fast, high resolution separations without the elevated back pressures required by sub-2 µm particles.

Beskrivelse: Fast method development of complex samples across the pH range from 1,5 to 10,5 with different mobile phases and temperature conditions.
Purospher® STAR RP-18 endcapped HPLC columns are designed for universal use. Basic, neutral and metal-chelating compounds can easily be separated with simple mobile phases – naturally without peak tailing. Thanks to its outstanding performance and stability, Purospher® STAR RP-18 endcapped offers maximum flexibility in method development. Robust methods can be developed over the entire pH range from 1,5 to 10,5. High pH-stability allows the separation of strongly basic compounds with alkaline eluents. The combination of high purity silica, best all-round retention characteristics, outstanding pH stability up to pH 10,5, and suitability for up to 100% aqueous mobile phases, make Purospher® STAR RP-18 endcapped an all-round top performance column, almost universal in its range of applications.

Beskrivelse: Routine inverted fluorescence microscopes for transmitted brightfield, phase contrast (optional for IT407 FL4 and IT407 FLD4 FLD) and fluorescence observations with IOS LWD W-Plan PH or U-Plan F objectives. Ideal for tissue culture research in clinical and biotechnology laboratories.

Beskrivelse: Purospher® STAR RP-8 endcapped, like Purospher® STAR RP-18 endcapped, is based on high purity silica and has an almost complete surface coverage. Thus, Purospher® STAR RP-8 provides excellent peak symmetry for acidic, basic and even chelating compounds, highest column efficiency in terms of the number of theoretical plates, and exceptional stability from pH 1,5 to 10,5. In addition, they are ideal for a wide range of applications. As the sorbent is less hydrophobic than Purospher® STAR RP-18 endcapped, analytes will typically elute faster on the C8 phase. Purospher® STAR RP-8 endcapped provides enhanced selectivity for positional isomers and symmetrical peak shapes for strongly basic and less hydrophobic compounds.

Leverandør: Avantor

Beskrivelse: Avantor® ACE® Method Development Kits (MDK) are designed to maximise selectivity, offering a powerful and reliable approach to UHPLC/HPLC method development. Based upon an ultra-inert, high efficiency silica, Avantor® ACE® phases incorporate the latest developments in LC stationary phase design, providing chromatographers with more choices for alternative selectivity, without compromising stability or robustness.

Leverandør: Avantor

Beskrivelse: Avantor® ACE® CN-ES combines CN polar selectivity with enhanced hydrophobicity, enabling the benefits of both interactions to be fully exploited. Extra phase stability and increased column lifetime is provided by an extended alkyl chain spacer between the silica surface and cyano group. Avantor® ACE® CN-ES is suitable for both reversed phase and normal phase separations.

Beskrivelse: This phase separating paper is impregnated with stabilised silicon, thus rendering it hydrophobic and it retains water, but allows solvents to flow through. The flow stops automatically when the entire solvent has passed through, this eliminates the need to use separating funnels.

Leverandør: Mettler - Toledo

Beskrivelse: Users can be guided through multi-step procedures with clear directions from measurement to cleaning. Measure comfortably using the joystick to control the automatic sampling pump, and avoid the added strain of manual sampling.

Leverandør: Avantor

Beskrivelse: Prevail™ HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail™ Carbohydrate ES are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.
