Cellulose Products

All of the cellulose based products that we offer are manufactured in the United States and have been through over 40 years of developmental refinements. The cellulose products are continuously being improved and have recently been expansed into a new line of products: the Depth Clear D line. This line has been developed to produce sheet material for the Pharmaceutical Industry. We have available: small discs, capsules, sheets and Lenticular modules of all sizes. This ensures that we have the correct filter for the flow rate that must be filtered whether a small scale testing, pilot plant or full production operation is needed. All cellulose products have been tested in a specific facility which verifies that the filter media meets all quality requirements and regluations.

Lenticular Stacks BioPharm

Specifically formulated to meet the performance demands of biopharmaceutical and biotech applications. The filter media utilize mechanical and electrokinetic adsorptive capture mechanisms to remove particles, microorganisms, colloids, and pyrogen from critical process streams. Purolator, a leader in depth media development, has invested years of research and development to create a range of filter grades to meet stringent application requirements.

Lenticular Stacks Beverage

DEPTH-CLEAR S Series depth filter modules, constructed of specially formulated cellulose media and inorganic filter aids, provide reliable particle retention and enhanced throughput for superior performance in critical applications. The filter media utilize mechanical and electrokinetic adsorptive capture mechanisms to remove particles, microorganisms, colloids and pyrogen from critical process streams. The module format allows the filtration process to occur within a totally enclosed environment. This eliminates the potential for atmospheric contamination and product loss through leakage.

Capsule - Cellulose Media

Purolator’s BIO-PRO Capsule-Clear DC Cellulose Depth Media filter capsules have been designed for simple, quick, and efficient filtration of fluids used in laboratory, pilot, and small scale applications. The compact design of the filter capsule reduces hold-up volume and minimizes exposure to hazardous chemicals. No adhesives, binders, or surfactants are used in the manufacturing process. The unit is thermally sealed to ensure integrity and is available in effective filtration areas from 120 cm2 to 900 cm2. Each capsule is vented with two o-ring sealed bleed valves and has 10 different fittings offered for the capsule inlet and outlet.

Cellulose Depth Sheets

Proprietary formulation process produces precision depth media that provides superior filtration and long on-stream life cycles. Particles are captured through a combination of mechanical capture and electrokinetic adsorption. Advanced manufacturing process controls result in very uniform filtration media and reliable lot-to-lot performance. All raw materials are subject to stringent quality control procedures to ensure consistent and uniform product. Filter sheets available in a wide range of shapes, sizes and hole configurations for exact fit up and installation in most filter press equipment. Very broad selection of grades offered within each media series to meet the flow and retention requirements of an application. Special formulations are available for high volume requirements. Special formulations and custom sheet sizes are available for large application requirements.

Soft Encapsulated Modules

Depth-Clear D is the combination of two proven Biotech products the Lenticular filter and the Bio-Process Container. The result is the first Lenticular filter system that is positively contained, and completely disposable. More importantly it is manufactured using Purolator LP’s Cellulosic Depth media which has been used in the Bio-tech industry for over 15 years.

The Depth Clear D product line is scalable for 1 cell to 32 cells with single layer media and up to 26 cells with dual layer media. It uses Purolator’s validated Pharmaceutical grade media: KP, KPLE and KC media. Micron rating ranges from 0.2 um nominal to 20 um nominal. Dual layer media come in a combination of 10um/ 0.45 and 20um/ 0.6um. These two medias were developed to for exceptional throughput when filter high cell debris centrate and high protein solutions.

BioPro Totes

Purolator Liquid Process Depth-Clear™ D Series Filter Housing is designed to meet individual customer requirements for a wide variety of applications in the food, petroleum, and chemical industries. This seal-less housing works in conjunction with the bagged filter that supplies all sealing requirements. The housing simply provides structural integrity to your filtration operations. Features and Benefits Process fluid enters the housing at the top of the filter bag, flows down into the inlet port of the bag contained in the housing. The unfiltered liquid pressurizes the bag causing the bag to expand and conform to the interior of the housing. The liquid then flows through the depth mediaretaining impurities, through to the center core and eventually out the core discharge port.
