EXP®2 Nano Traps


Sorry but this item is currently unavailable.



The next-generation EXP2 Nano Trap System is a breakthrough in trapping hardware design and provides the finest low-volume hardware and connections to minimize extra column effects and sample dispersion.  The EXP2 Nano Trap packed bed is extremely versatile: robust for applications calling for trapping in one direction followed by elution in the reverse while adding the absolute lowest swept volume for vented-trap applications where the trap is loaded and eluted in the same direction. Applications for the EXP2 Nano Trap include general sample cleanup, sample concentration and removal of detergents or salts at UHPLC pressures.

EXP2 Nano Traps are available in 3 formats: 10-32 threaded connections for 1/16” tube ports and 6-40 or 6-32 threaded connections for 1/32” tube ports.  Multiple bed volumes and bonded phases allow customizable formats to achieve the separation, clean-up, and concentration that will be effective for your specific method.  

The new hand-tight EXP2 fittings from Optimize allow the Nano Trap to achieve the highest performance at UHPLC pressures while maintaining a small profile to fit tight spaces in switching or injection valves.  The Nano Trap is best coupled with narrow bore (25um, 50um, 100um) PEEKsil tubing to deliver top performance.  The EXP2 Nano Trap is available as individual packed beds or as a kit with PEEKsil Tubing, EXP2 fittings and EXP2 Driver.

EXP2 Nano Trap Kits include: 1 EXP2 Nano Trap, 4 Hand-Tight EXP2 Fittings with Ti-Lok Ferrules, 1 EXP2 Driver and 2 pieces of 50um i.d. X 100mm PEEKsil tubing (1/32” OD for 6-32 / 6-40 THD and 1/16” OD for the 10-32 THD style).
