New range of HPLC Syringe Filters
Besides our range of 25mm ProFill HPLC Syringe Filters we are going to introduce a new range of 30mm Filters. They are characterized by an injection moulded coloured ring around the housing and all include a glass fibre pre-filter. They will be available in four different types of membrane in pore sizes of 0.2µm and 0.45µm. As hydrophilic membrane types we are going to offer Regenerated Cellulose (RC), Nylon (PA) and PVDF with glass fibre pre-filter; in addition PTFE with glass fibre pre-filter as a hydrophobic membrane. Besides the colour-coding the print of the membrane type along with the pore size on the housing guarantees product safety during usage. This range of filters is going to replace our current ProFill PLUS range of filters, as it will offer an increased effective filter area (4.91 cm² instead of only 3.14 cm²) which is especially important for heavily particle loaded samples requiring the glass fibre pre-filter.
Furthermore we will add to our line of filters 17mm versions. While the design of housing and injection moulded ring is similar to those of the 30mm ones with glass fibre pre-filters, all products – except for the PVDF filters – of that range do not include any prefilter. They will be available with one of the following membranes in 0.2µm or 0.45µm pore size: PTFE, Regenerated Cellulose (RC), Nylon (PA) and PVDF. These filters should mainly be used for small sample volumes where the dead volume should be kept to a minimum.
