Supplier: METTLER TOLEDO

The XS and XA analytical balances provide fast and accurate weighing with flexibility. This is achieved with the introduction of SmartGrid technology, with the gridded weighing pan supported at the rear of the weighing chamber. Therefore the draught shield and drip tray can be completely, quickly and easily removed. The draught shield can be set to open the right hand door with the left slider and vice versa making loading more efficient. The design also features a large backlit touch screen that facilitates direct access to all functions and a standard range of applications, that include simple weighing, percentage weighing, piece counting and statistics. Software can be downloaded from the internet via RS232 connection.

Supplier: Avantor

Ready-to-use pH buffers are manufactured in large lots to stringent specifications and utilise quality control procedures to reduce lot-to-lot variability. You can eliminate the time and expense of preparation and standardisation of solutions, helping streamline high-volume analytical work in applications such as quality control.

Supplier: Avantor

The Avantor® ACE® Excel® C18-AR phase utilises a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for ‘standard’ C18 column separations, but is additionally recommended for separations that involve compounds containing aromatic functionality.

Agarose high resolution (HR) has melting, max. 90 °C, and gelling temperatures (32,5 to 38 °C), but differs from traditional low melting point molecular biology grade agaroses in the gel separation range. Using this agarose in electrophoresis allows fine and consistent resolution of nucleic acids below 1000 base pairs, which differ by only a few base pairs. The properties of Agarose HR allow consistent gel separations (analytical and preparative) and performance of in-vitro translation and transcription mapping, as well as in-vivo ligation and transformation. For analytical gel separation of DNA/RNA below 1000 base pairs, where a higher gel strength for ease of manipulation is required, we recommend the use of Agarose, high resolution, Electran (43655).
