Dissolution Accessories Filter Vials streamline the process of sample filtration by combining the functions of HPLC vials, HPLC caps, syringes, and syringe filters into a single system. With DA Filter Vials, you can easily convert unfiltered samples into filtered, autosampler-ready vials, simplifying your sample preparation. Each vial comprises two components, a chamber and a plunger. The design features a filtration membrane at one end of the plunger and a pre-attached cap or septum at the other end. When the plunger is pushed through the liquid in the chamber, positive pressure drives the filtrate up into the plunger's reservoir. Air is released through the vent hole until the evaporation seal is activated, creating an airtight seal.
The filtration vial is compatible with any autosampler designed for standard 2ml vials with a 12mm x 32mm profile, enabling automated sample injection sample injection into your instrument.

Usage Instructions,

Step 1, Choose a filter vial that is suitable for your sample. (Refer to the Chemical Compatibility Guide. If your solvent is not listed, see page 3 for Technical Support contact information.) Pour the sample to be filtered into the chamber, ensuring not to go beyond the fill line. Each filter vial can hold roughly 0.4ml.

Step 2, Insert a plunger into each filter vial until the membrane makes contact with the liquid.
A: For manual filtration without the Compressor: Gently press the plunger and the chamber together using your thumb and forefinger until the evaporation seal is fully engaged.
B: For filtration using the 16 position compressor (part no. PSxxxx): Place the Filter vial chambers (up to 16 position ) into the slots of the compressor filling plate. Attach the compressor filling plate to the compressor. Lower the compressor handle until it touches the filter vial lid. Gradually press down the handle until all the plungers are completely depressed and the evaporation seals are fully engaged.

Step 3: The sample filter vial is now ready for analysis.
A: Insert the filter vial into a compatible* autosampler for automated sample injection into your instrument.
B: Pierce the septum and use a syringe to manually draw the filtered sample for injection into your system.

Safety Precautions:
Avoid overfilling the filter vial or compressing the device at an angle before the airtight seal is secured.
This could cause liquid to escape through the air vent holes, leading to sample loss or personal injury.
