FAQ
| Question | Answer |
|---|---|
| What is the sample volume range for the Pellicon II Mini system? | The Pellicon II Mini system is capable of volumes in the approximate range of 1- 50 L concentrating down to 100 mL. More or less volume can be processed depending on the individual needs of the operation, ie. process time, sensitivity of product, etc. |
| What is the part number for the Gauge Kit that is used with the Pellicon XL? | Gauge Kit for Pellicon XL Device (0-60 psi): Part number XXPXLGAGE, 1 per kit. Includes an inlet pressure gauge and t-fitting. This gauge is recommended when the Pellicon is used in the absence of a Labscale TFF system in order to ensure that the pressure on the tubing is known and not allowed to exceed it's recommended maximum. |
| Can I use TFF systems to separate two proteins based on a significant difference in their respective molecular weights? | As a general rule ultrafiltration does not provide high efficiency separations of protein mixtures. However, it may be possible to effect this type of separation between two proteins that have at least 10 X difference in molecular weight and if there is an ultrafiltration membrane available with a NMWL rating between the molecular weight of the two proteins. These separations are also generally more successful with dilute protein solutions and if run at low pressure. |
