Cleaning Verification TOC Swabs

TOC Cleaning Validation Kit is able to simplify sampling as a cleaning validation program. This uses a proprietary process to further clean swabs and vials. These kits are suitable for total organic carbon (TOC) analysis. Lot number traceability and quality control.
Scope of Application

TOC analysis as part of a cleaning validation protocol
As part of other cleaning validation protocols
Non-organic liquid sampling surveys of contaminated sources
Biopharmaceutical clean validation sampling
Total Organic Carbon Sampling

What are the advantages of cleaning verification swabs?

1、Matching independent combination packaging:

It is a convenient, safe and organized method of transportation
Swabs and vials from the storage area to the sampling point and then to the laboratory, the possibility of contamination is very small;
2、TOC cleaning verification swabs

TOC content <50 µg/L, <50 ppb, safeguarding the swab itself from interfering with test data;
Double, double knit polyester head for entrapment of contaminants; knitted construction during sampling. This is to maximize sample collection and release into the diluent to provide excellent recoveries;
Separate handle with notch for placing head into vials for minimal handling and sampling;
100% polypropylene handles to ensure no other contaminants and excellent chemical resistance.
3、Sample vials

Total Organic Carbon content (<10µg/L, <10 ppb), ensuring that the swab itself does not interfere with the test data;
Pre-washed borosilicate glass bottles have an integral cap and septum designed for easy sampling and analysis.
Diaphragm thickness – 1.34 mm (0.053″)
◎ Polyethylene overlay protects septum surface from pre-analytical contamination.
◎Sloped shoulder design reduces swab tip area for lower TOC.
◎TOC instrument manufacturer approved for use.

4、Labeling

Cleanroom is suitable for identification and traceability of vial samples.

5. Containers/Boxes

Double bagged and packaged in cleanroom compatible polypropylene boxes.

Cleaning Verification Swab Kit Test Procedure

Verify that the equipment is clean and that the operator is dressed appropriately for testing (clean gloves, mask, gown, hairnet, clean environment).
Take a “clean” Low TOC swab in the Certified Low TOC vial.
Fill the vial with 40 ml of ultra-pure Low TOC water and seal.
Vortex the vial for 15 seconds.
Fill another certified low TOC vial with 40 mL of ultrapure, low TOC water and seal. This will be used as a “blank control”.
Run a TOC test through the “control blank” dosing vial and water level of the instrument. The unit of measurement should be μg/L.
Pass the vial with the swab inside through the TOC test device. Measurements should be in μg/L.
Subtract the “control blank” from the swab vial to get the final measurement. All measurements should be in μg/L. Our goal is less than 50 μg/L.
