Sample Preparation
TITAN2® 30mm Filters
Cat. no. 44525-PV, 30mm PVDF Filters with Porosity of 0.45µm
Cat. no. 44525-NP, 30mm PTFE Filters, 100 pack
- Banded polypropylene housing ensures lab safety preventing the housing from bursting
- Color-coded housing allows for easy identification of membrane
- Most 30mm filters have a 1 micron glass pre-filter
- For sample volumes of 2mL to 100mL
- Retention volume < 115µL
- Maximum operating temperature: 100°C autoclave at 125°C for 15 minutes
- Maximum operating pressure approximately 100 psi
Instructions for Use
- To minimize fluid retention on the membrane, draw 1mL of air into the syringe before filling. This will also serve as a final air purge. Draw sample into the syringe until full.
- Secure the inlet of the filter to the filled syringe with a twisting motion, being careful not to use excessive force.
- Hold the syringe with the filter attached vertically. This will permit proper wetting of the membrane preventing air block and initiating enhanced and proper flow rates.
- Depress the syringe plunger gently. It is recommended that the first 0.25 to 0.50mL of filtrate be discarded.
Note: If increased pressure is required this is an indication that the filter is maximized and needs to be changed.
