Graduated flasks

Volumetric flasks provide precise results in chemistry and pharmacy. They are not scaled, but have a single ring mark that is drawn all the way round the neck to avoid reading errors.

The narrow neck results in high setting accuracy. In addition, volumetric flasks have bulbous curves in the upper area so that any gas bubbles that form can escape from the solution more easily. However, if there are gas bubbles in the solution, the volumetric flask must be swivelled slightly so that the bubbles rise to the top. In addition to volumetric pipettes and burettes, volumetric flasks are therefore the most accurate volumetric instruments in the laboratory for analysis.

 Plasmid Purification-Kits I-Blue Mini / Midi

IBI Scientific

For rapid and efficient extraction of plasmid DNA from bacterial cells.
The method is based on a combination of alkaline lysis and RNase treatment to obtain a clear lysate with minimal genomic DNA and RNA contamination. The bound plasmid DNA is washed and finally eluted by adding a buffer. The test kit contains the I-Blue Lysis Buffer, an optional colour indicator. The use of this indicator prevents common handling errors that impair efficient cell lysis and neutralization....

 DNA Markers for Gel Electrophoresis

Cleaver

The ready-to-use DNA markers run precisely and produce a sharp, well defined ladder. They are available in six molecular weight ranges.

 Micro plates Riplate® magnetic

Ritter

Riplate ® magnetic plates have been specially developed for the reproducible magnetic separation of DNA and proteins and can also be used for cleaning, mixing or centrifugation of samples as well as for the storage and preparation of substances.
For the filtration of proteins as well as for DNA extraction, an automated method called magnetic separation is commonly used. The technology is based on magnetic particles which allow the fast and efficient sample preparation with high throughput. The sustainability of these products as well as reliable analysis results are ensured by the production under cleanroom conditions (class 8). The plates are in line with the SBS standard (Society for Biomolecular Screening) and have been especially developed for the magnetic separation technology....
