Ohaus 8001-MN Spring Scales Scale, 250 g x 10 g

The KP-47U is designed for vacuum filtration of liquids under sterile conditions, making it ideal for microbiological testing, water analysis, and pharmaceutical sample preparation. Its aseptic design helps prevent contamination during critical filtration processes.

This unit is compatible with 47 mm membrane filters, a widely used standard in laboratory filtration. It also supports 41 mm prefilters, allowing users to handle samples with higher particulate loads efficiently.

The KP-47U includes a recessed filter support, which prevents membrane damage or tearing during assembly, and a graduated 300 mL funnel for accurate volume measurement. It also supports vacuum pressures up to approximately 25 inHg, enabling efficient filtration.

The unit is made from durable polysulfone, which offers excellent chemical resistance, impact strength, and autoclavability. This makes it a reliable and lightweight alternative to glass filtration systems while maintaining long-term durability.

The unit features a funnel cover with a vent port that can be connected to a sterile syringe filter, allowing air exchange without introducing contaminants. This design supports safe, sterile filtration workflows in regulated environments.
