Complete storage solution for HPLC fractions comprises a 2ml round deep well microplate and high integrity cap mat seals. The design of the 2ml deep well plate – which provides scientists with a genuine 2ml working volume in a 45mm height plate – is now coupled with a choice of specially designed cap mats. These flexible, re-usable cap mats prevent evaporation and allow transport and storage of samples in the 2ml plate without the need for expensive heat seals or leaky adhesive-based seals. To ensure complete confidence in the integrity of sealed HPLC autosampler or fraction collector samples, flexible pre-scored silicone cap mats with double O-ring are included in the package.
