Simultaneously Filters Up To
24 Samples in Seconds
- Reduces labor time by 20 minutes per carousel over the conventional syringe filter technique.
- No need to use cumbersome, individually wrapped, disposable syringes. Use disposable pipette tips which are less costly, easier to use, and require less bench space.
- Designed for use with Waters Alliance* HPLC systems.
- Pall's HPLC certification ensures that analytical results will not be compromised by extractable filter material.
- No cross-contamination. Each 1.9 mL well is individually sealed, ensuring your sample will accurately dispense into the Waters Alliance sample carousel* with no crosscontamination or splashing.
- Materials of construction are identical to Pall's Acrodisc® syringe filters; if you are currently using Acrodisc syringe filters, this will reduce the requirements for validation of the AcroPrep 24 filter plates.
- Can be used with any conventional 12 x 32 mm vials; simply transfer your filtered samples from the Waters Alliance sample carousel to any HPLC sample carousel that houses 12 x 32 mm vials and save both time and labor.
- Can be used to process fewer than 24 samples. Simply label used wells or isolate unused wells with parafilm for application at a later time.
*The Water's Alliance 2690 Sample Carousel kit (PN WAT270328) can be ordered directly from your local Waters sales office or contact Waters Corporation at 800-252-4752 (in the U.S.) or 508-478-2000.

Instructions for Use
The AcroPrep 24 Filtration System operates by vacuum. Conventional lab pumps such as Pall Life Sciences’s 115 V (PN 13157) or 230 V (PN 13158)Vacuum/Pressure pumps are ideal for use. For maximum convenience, we recommend the use of snap-cap vials to eliminate the need to remove vials for screw capping after filtration.
- Attach vacuum hose to the barbed connection on the base.
- Place your Alliance sample carousel with empty 2 mL vials into the manifold.
- Place the filter plate onto the manifold. The filter plate has a numerically sequenced label that matches the carousel’s sample numbers.
- Pipette 1.7 mL (1,700 μL) of sample into each of the filter wells.
- Apply vacuum.
- Allow vacuum to run until all wells are evacuated.
- Shut off vacuum source. Dispose of filter plate.
- Cap sample vials and place the sample carousel into the Waters Alliance HPLC system or simply transfer the
vials to any HPLC sample carousel that houses 12 x 32 mm vials.

The cleanliness of the AcroPrep filter plate results in very low levels of extractables, therefore eliminating the need to pre-rinse the filter.MP>
Vacuum General Information
- Do not exceed a vacuum level of 56.0 cm (22 in.) Hg.
- Allow vacuum to run until all filter wells are evacuated. Continue running vacuum for 10 to 20 seconds to eliminate potential dripping of samples from tips when plate is removed.
