The pump is connected with tubing between the process sample reservoir and the feed port on the Minimate TFF Capsule. Tubing connected to the retentate port is returned to the reservoir. This allows flow of product across (tangential to) the membrane surface to create a sweeping action that helps prevent membrane fouling by reducing buildup of particles and product on the surface.
Page 16
Tubing connected to one of the filtrate ports serves to carry the filtrate (permeate) away from the device. The other filtrate port can be used as a vent for draining all liquid in the tubing after the process is finished.

Sanitization (recommended for critical applications) Introduction If required, the Minimate TFF Capsule can be sanitized prior to use. The following solutions can be used to sanitize and depyrogenate the capsule. • 0.1 to 0.5 N NaOH at 35°C to 45°C •...
Buffer-conditioning (optional) Introduction The buffer-conditioning step is used to precondition the Minimate TFF Capsule into the sample buffer (equilibrating solution) before the sample is added. This adjusts the pH and prevents the sample from being diluted with water, which may lower the ionic strength and possibly cause precipitation of product or other sample components.

The original NWP of the Minimate TFF Capsule is essential to calculate as it is used as the basis to determine membrane recovery, i.e., how effectively the membrane was cleaned.
Page 37
The following tables may be used as an example for recording data and calculations. Below table is for recording data and calculating NWP. This table is available to print at the rear of the document. Minimate TFF Capsule and Minimate EVO TFF System Operating Instructions 29870317 AA...
Page 38
NWP (LMH/TMP @ 20°C) = Filtrate flux rate (mL/min/cm ) × 600 Filtrate flux rate (LMH) = Filtrate flux rate (LMH) × Temperature correction factor (TCF) at operating temperature Minimate TFF Capsule and Minimate EVO TFF System Operating Instructions 29870317 AA...

Example determination of NWP on a Minimate TFF Capsule Water filtrate flux rates were measured for a Minimate TFF Capsule at TMP of 5, 10, and 15 psi. The temperature of the water was 16°C. Determine the original normalized water permeability (NWP).
Page 40
(correcting water permeability for temperature; from 16°C to 20°C) Temperature correction factor from Table 5.2, on page 39 for 16°C = 11.0°C LMH/psi x Normalized Water Permeability = 11.0°C × 1.109 = 12.2 LMH/psi Minimate TFF Capsule and Minimate EVO TFF System Operating Instructions 29870317 AA...
Carefully transfer the retentate line into a 25 mL graduated cylinder. Turn on the pump and allow remaining liquid to be pumped out. Record the volume. This volume is the system hold-up volume. Minimate TFF Capsule and Minimate EVO TFF System Operating Instructions 29870317 AA...
Page 42
Stop the pump. If any liquid remains in the reservoir, add it to the cylinder. Record the volume in the cylinder. This is the minimum working volume for the system. Minimate TFF Capsule and Minimate EVO TFF System Operating Instructions 29870317 AA...
Capsules are 100% integrity tested. Therefore it is not necessary to perform an integ- rity test on a new Minimate TFF Capsule. However, for critical applications or if the capsule will be reused, it is recommended that a forward flow air integrity test be performed to confirm integrity before and after use.
Page 44
This protocol describes performing the procedure using a peristaltic pump to generate airflow. For more accurate testing, a regulated, compressed air or nitrogen supply must be used. The below image shows a setup for air integrity testing of the Minimate TFF Capsule. Part Description...

6.1 Flushing and cleaning after use Flushing and cleaning after use If the Minimate TFF Capsule is to be reused, it must be cleaned after use and properly stored. Recommended cleaning solutions and protocols are given below. The recommended cleaning agents for Omega membranes in the Minimate TFF Capsule are as follows.
It is also important to develop a positive pressure profile along the entire membrane path length (feed to retentate). The procedure below will accomplish both requirements. Minimate TFF Capsule and Minimate EVO TFF System Operating Instructions 29870317 AA...
Start the pump and increase speed until retentate flow rate is 50 to 80 mL/min. Flush about 200 mL to drain to assure that a thorough flushing is accom- plished. Minimate TFF Capsule and Minimate EVO TFF System Operating Instructions 29870317 AA...
Do not exceed a feed pressure of 2 bar (30 psi). Pump at least 250 mL of the water through the retentate tubing and 250 mL through the filtrate tubing to the drain (>500 mL total). Minimate TFF Capsule and Minimate EVO TFF System Operating Instructions 29870317 AA...
