Lab Consumables
The high quality Orientfiltr syringe filters ensure reliable elimination of both particles and micro organisms in the sample preparation process, providing consistent and reliable experimental results for a range of samples and applications. Orientfiltr syringe filters protect chromatography columns by preventing the accumulation of fine particles in the column, which forms premature blockages
Futures:
• Sample preparation for HPLC and UHPLC analysis
• Protect columns and extend column lifetimes
• Low sample volume compatibility
• High integrity sample preparation
• Color coding for easy identification and selection of the correct membrane and pore size
• Integrated prefilter options for enhanced removal of particulates
