The Anotop disposable syringe filter contains the unique Anopore inorganic membrane in a polypropylene housing, complete with luer-lock fittings. The filters are designed for use with most organic solvents and aqueous materials. They come in three varieties each with various advantages.
Anotop Standard range in two sizes, the 10mm filter is suitable for volumes up to 10ml. The 25mm filter is suitable for volumes up to 100ml.
Anotop Plus Analagous to the standard range but with an added glass microfibre pre-filter for difficult to filter samples
Anotop IC Specially designed for Ion Chromatography as these devices ensure very low levels of anion leaching.
Anotop LC is designed for HPLC sample preparation
Guide to…Syringe Filter Properties
Identifying the filter material most suitable for your application based upon the nature of the liquid or gas you are filtering will ensure the best performance of your filter. Each syringe filter contains a membrane filter of a set diameter and plastic housing with luer connections used for connecting to syringes (or in-line hosing systems).
The membrane filter material has differing chemical and physical properties such as hydrophobicity, flow rate, extractables and protein retention making them suited to differing applications. Once you have selected the most compatible filter material, you will need to consider what pore size is most appropriate for your application and what diameter filter is suitable for your sample volume.
Membrane Material
| Membrane Material | Protein binding | Hydrophilic/Hydrophobic | Chemical resistance | Applications |
| Hydrophilic PTFE | Low | Hydrophilic | High | Purification of HPLC organic and solvent/aqueous solutions |
| Hydrophobic PTFE | Low | Hydrophobic | High | Filtration of solvents |
| PES | Low | Hydrophilic | Low/Medium | Purification of tissue culture solutions, buffers |
| PVDF | Low | Hydrophilic | Medium | Filtration of protein solutions |
| NYL | Medium | Hydrophilic | Medium | Filtration of aqueous and solvent/aqueous mixtures |
| CA | Low | Hydrophilic | Low | Filtration of protein solutions |
| CN | High | Hydrophilic | Low | Filtration of aqueous solutions where protein binding is not a concern and microbioloigical applications. |
| RC | Low | Hydrophilic | Medium | Filtration of aqueous and organic solvents and protein recovery applications. |
Filter diameter
High particulate loaded samples with tend to block the pores in the membrane more quickly so the total volume you can filter through a certain diameter syringe filter will vary greatly. Please take the below figures as a guide only.
- 13mm diameter - for samples <10ml
- 25mm diameter - for samples <100ml
- 33mm diameter - for samples <250ml
For samples that are very particle ladden, it is recommened that you try pre-filtering your sample. Pre-filtering can be achieved with a number of different filters, such as glass microfibre. Some syringe filters come with an in-built pre-filter.
