4T Laboratory Filters

Stainless Steel Pyrex Laboratory Filter

The 4T Series Laboratory Filters are designed 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 50 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 now includes our new dividing ring to provide for double filtration.

ErtelAlsop is more than happy to work with you to modify our existing designs to meet specific requirements.
