PRE-PACK SCREENS
Plus 10 PrePak Screen has a high open area to cut down on waiting for samples in low-yield wells.
With 10 times the open area and 10 times the filtration capacity, these 20% open area screens are ideal for Long Term Monitoring (LTM) of natural attenuation using low purge or passive sampling. High open area minimizes stagnant water to cut sampling time in low-yield wells. UltraFine filter pack can reduce turbidity by orders of magnitude and remove silt size particles, preventing siltation of the well.
