The 4T Series lab filter is for use in laboratories to perform filtration trials and scalability studies. These units are constructed of 316 stainless steel with stainless steel cylinders for pressures up to 60 PSIG, or a protected Pyrex glass cylinder for filtration up to 30 PSIG. Stainless steel cylinders can be furnished with an optional heating or cooling jacket.

When running trials, which require more than one filtration stage, ErtelAlsop, includes a Dividing Ring. This design allows for an infinite number of filtration stages, providing unlimited flexibility.

Constant flow pumps, compressed air or inert gas can be used to flow liquid through the filter media. The O-Ring seal design provides the versatility to use a variety of filter media of different composition and thickness.
