The Laboratory Syringe Filters category supports laboratories that need to separate liquids, solids and dissolved components by differences in volatility, solubility, particle size, density or affinity. The range spans routine bench requirements and more specialised applications where material choice, control and repeatability become especially important.
Correct glassware geometry, membrane selection, vacuum level and chemical compatibility directly affect recovery, purity and processing time. This is why laboratories should assess sample volume, chemical compatibility, temperature and vacuum conditions, and pore size or retention before choosing a product, rather than relying only on capacity, appearance or headline specifications.
Most methods combine sample preparation with a selected separation mechanism, controlled transfer or heating, collection of the target fraction and cleaning between runs. The same principle applies across chemistry, food, environmental, pharmaceutical, industrial and teaching laboratories: control the inputs, use compatible equipment and document the conditions that can influence the result. As part of the Distillation, Separation & Filtration Equipment range, these products can be selected with the equipment and consumables used before and after this stage.
Our Laboratory Syringe Filters range
Our collection covers when to use a pes syringe filter, benefits of gvs separa minivials, Sartorius minisart filters available for sterile applications, and choosing the correct pore size, giving laboratories practical choices for routine work and more specialised applications.
When to use a PES syringe filter
PES (Polyethersulfone) membranes, like those in the LLG Spheros range, are ideal for aqueous solutions and provide high flow rates with very low protein binding. Selection should take account of sample volume, chemical compatibility, and temperature and vacuum conditions. It is also worth checking cleaning, replacement and storage requirements before the item becomes part of a routine procedure. Used correctly, this part of the range helps laboratories build a compatible separation train that protects recovery and reduces unnecessary transfers. The result is a setup that is easier to train, document and maintain.
Benefits of GVS Separa Minivials
Separa minivials combine a syringe filter, a vial, and a cap into a single device, allowing you to filter your sample directly into the analysis-ready container, reducing handling and contamination risks. When comparing options, consider chemical compatibility, temperature and vacuum conditions, and pore size or retention. The correct choice should fit the sample, expected workload and any equipment already used in the method. In practice, this supports efforts to build a compatible separation train that protects recovery and reduces unnecessary transfers. It also gives staff a clearer and more repeatable procedure when multiple users or shifts share the same equipment.
Sartorius Minisart filters available for sterile applications
Many Sartorius Minisart units, such as the NML 0.45 µm model, are provided in sterile packaging for critical life science and microbiological workflows. Before ordering, compare temperature and vacuum conditions, pore size or retention, and connection size. A product that fits the complete workflow will generally be easier to validate, maintain and reorder. This is especially valuable when teams need to build a compatible separation train that protects recovery and reduces unnecessary transfers. Consistent handling also reduces the risk of variation between batches or operators.
Choosing the correct pore size
Typically, a 0.22 µm pore size is used for sterile filtration (removing bacteria), while a 0.45 µm pore size is used for general clarification and removing particulates before HPLC or GC analysis. When comparing options, consider pore size or retention, connection size, and separation principle. The correct choice should fit the sample, expected workload and any equipment already used in the method. Used correctly, this part of the range helps laboratories build a compatible separation train that protects recovery and reduces unnecessary transfers. The result is a setup that is easier to train, document and maintain.

Frequently Asked Questions
When should I use a PES syringe filter?
PES (Polyethersulfone) membranes, like those in the LLG Spheros range, are ideal for aqueous solutions and provide high flow rates with very low protein binding. The final choice should reflect separation principle, sample volume, and chemical compatibility, as these points influence day-to-day compatibility and repeatability.
What is the advantage of GVS Separa Minivials?
Separa minivials combine a syringe filter, a vial, and a cap into a single device, allowing you to filter your sample directly into the analysis-ready container, reducing handling and contamination risks. Before ordering, confirm separation principle, sample volume, and chemical compatibility and any accessories or consumables needed for routine use.
Are Sartorius Minisart filters available for sterile applications?
Many Sartorius Minisart units, such as the NML 0.45 µm model, are provided in sterile packaging for critical life science and microbiological workflows. For syringe filters, also check separation principle, sample volume, and chemical compatibility so the product fits the complete procedure.
How do I choose the correct pore size?
Typically, a 0.22 µm pore size is used for sterile filtration (removing bacteria), while a 0.45 µm pore size is used for general clarification and removing particulates before HPLC or GC analysis. For syringe filters, also check separation principle, sample volume, and chemical compatibility so the product fits the complete procedure.
What should I check before ordering syringe filters?
The most important points are separation principle, sample volume, chemical compatibility, and temperature and vacuum conditions. Laboratories should also consider how the item will be stored, prepared, cleaned and replaced over its working life. Laboratories should compare separation principle, sample volume, and chemical compatibility and document the selected setup for consistent use.
