Hold the syringe with the filter pointing up and “top off” by pushing a few drops through the filter. Place the filter tip over the collection container and push the sample through a syringe filter by applying gentle positive pressure. To purge the syringe filter and maximize sample throughput, remove the filter from the syringe and draw air into the syringe. Then reattach the filter and push the plunger to force some of the air through the filter.
Feb 17, 2020 · Attach the filter securely to the syringe using a twisting motion. Pour the sample solution from the unpreserved fill bottle into the top of the syringe leaving space for the plunger. Reinsert the plunger. Note: The individually packed sterile syringe filter can be held in the original package to minimize contamination while attaching the syringe.

organisms in the sample preparation process, providing consistent and reliable experimental results for a range of samples and applications. Titan3 and Target2 syringe filters protect chromatography columns by preventing the accumulation of fine particles in the column, which forms premature blockages. Sample preparation
Sep 28, 2016 · Load the sample into the syringe. Attach the filter securely with a twisting motion. With a luer slip syringe, this is about one quarter turn as the filter is pushed on. If the syringe has a luer lock (as in this example), fix it firmly but do not over-tighten. Hold the assembled syringe and filter vertically to wet the membrane evenly.
To filter your sample, simply attach the appropriate syringe filter to the NORM-JECT and HENKE-JECT syringe and depress the plunger, capturing the effluent in a collection vial. Be sure to choose the correct volume syringe for the sample volume you wish to filter.
The purpose of using syringe filters for sample prepara-tion prior to analysis is to protect analytical equipment and columns. Sartorius Minisart® PP filters reliably remove particles from your samples without adding unwanted extractables or leachables. HPLC certified HPLC Procedure Column C18: 250 × 4.6 mm, Flow Rate: 1 ml/min, Wavelength
Pall’s IC Acrodisc syringe filters have been optimized for ion chromatography sample preparation applications. Available in both 13 mm and 25 mm formats, the syringe filters contain a hydrophilic polyethersulfone (PES) membrane that has undergone several washing steps ensuring the product has low conductivity detectable extractables.
Whatman MashPrep Syringe Filters allow you to filter corn mash sample for HPLC or other analytical technique quickly and efficiently. This filter reduces the number of filters needed to complete sample preparation, saving time, money and hand strain. Nylon membrane is hydrophilic and can be used for aqueous and/or organic samples.

General description. Millex® sterile syringe filters are ideal for sterilizing organic solvents, aqueous solutions or air/gas. Many sample preparation methods specify Millex filters because of their unsurpassed quality and consistency. Millex filters not only feature minimal hold-up volume and faster flow rates, but they also withstand higher
the syringe filter in replicates of n=10, and a new filter was used each time. Processing was performed using each filter and a new filter each time, resulting in 10 individual preparations for each filter type (70 prepared) ready for injection using the Cannabis Analyzer for Potency™.
