4mm syringe filters are colour-coded providing easy identification of membrane and porosity. Their enhanced luer-lock inlet provides secure connections and eliminates filter 'blow-off'.
4mm filters can often be used in place of larger filters and are ideal for use with sample volumes of <1ml, often used with HPLC applications — if you require a higher capacity, see our 13mm filters or 25mm filters.
• Retention volume: <7.5µl
• Max. operating temp: 100°C
• Max. operating pressure: 75psi
• Autoclave: sterilise by dry heat at 121°C for 15 mins
