Description

PALL 4501 Acrodisc Syringe Filters with PTFE Membrane - 0.45 µm, 25mm (1000/pkg)Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build up and reduce system downtime. Sample filtration using syringe filters containing 0. 45 m (HPLC) or 0. 2 m (UHPLC) pore size membranes will also extend the life of chromatography columns

Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build-up and reduce system downtime. Sample filtration using syringe filters containing 0.45 μm (HPLC) or 0.2 μm (UHPLC) pore size membranes will also extend the life of chromatography columns by preventing particulate from blocking the flow path between the column packing.

PTFE membrane is highly chemically compatible for the filtration of harsh solvents that can destroy other membrane materials. PTFE is a hydrophobic membrane, so it will repel water and is not suitable for the filtration of aqueous solutions.

As well as being suitable for the filtration of organic solvents in applications such as HPLC and UHPLC sample preparation, the hydrophobic nature of the PTFE membrane makes these syringe filters ideal to use in gas filtration or as a moisture barrier in venting applications.

Excellent tamp!
Size: 53mm, Size: 53mm
Love the tamp! The original one my machine came with was not great and I needed to buy one. I’m glad I picked this item, creates the perfect tamp and my expresso has been flowing much smoothly ever since

Would recommend.

Very well made. Works like a charm. I like palm tampers and this one makes it a lot easier to get a level tamp!

It is heavy
Size: 58.3mm, Color: Black
Item was as described and shipped promptly. It is heavy and works well with my portafilter. I haven't had it long enough to really evaluate how helpful it is.

Great little temper
Size: 53mm, Color: Silver
Works great! Only problem is that it doesn’t have that feel of tamping. Wish I had more feedback. It just goes down very easily and doesn’t have that feeling of solid tamping. Now that doesn’t mean it’s not doing its job. Works fine but would like some manual feedback.
