Merck takes pride in manufacturing the most reliable performance syringe filter devices. MM syringe filters are designed and manufactured to minimize column clogging and maximizing performance.  
| 
|  | 4 mm Millex® filters Sample volume: ≤ 1 mL
 Features: Very low nonspecific binding and hold-up volume minimizes loss of small samples during filtration.
 
 
 |  | 
|  | Millex-LCR filters for HPLC Sample volume:  ≤100 mL
 Features: Low extractable filters for both aqueous and organic solvents.
 |  | 
|  | 
| 
|  | 13 mm Millex® filters Sample volume: 1-10 mL
 Features: Overmolded design for higher operating pressures and faster filtration
 |  | 
|  | IC Millex® filters for ion chromatography Sample volume: 1-10 mL
 Features: Low binding, low extractable PTFE membrane removes particulates from aqueous and mild organic solvents for cleaner IC spectra
 |  | 
|  | 
| 
|  | 25 mm Millex® filters Sample volume: ≤100 mL
 Features: Filters with polyethylene housings available with a wide selection of membranes
 |  | 
|  | HPF Millex® filters for high particulate filtration Sample volume: ≤100 mL
 Features: Integrated prefilter yields two to four times greater throughput than traditional syringe filters.
 |  | 
|  | 
| 
|  | 33 mm Millex® filters Sample volume: ≤100 mL
 Features: Larger filter surface (almost 20% more surface area than 25 mm filters) for increased flow rates and throughput.
 |  | 
|  | Samplicity® filtration system with Millex® Samplicity® Filters Sample volume: 300 µL – 2 mL
 Features: Prepares multiple samples simultaneously; ergonomic design simplifies membrane filtration; vacuum-powered device improves throughput and sample recovery.
