Materials
- Environmental swab with 10 mL Buffer Solution (1 per sampling site) provided by Capella Innovation
- Permanent Ink Marker
- Predetermined sampling site of approximately 4” x 4” (~ 100 cm2), or for more intricate surface areas, an equivalent area estimation or a “per part” sample is acceptable.
- Gloves (sterile)
Sampling Procedure
- With gloves on, remove swab from sterile packaging.
- Carefully unscrew cap of sampling device – swab is attached to the lid of the cap.
- Gently press out excess solution from sampling swab by pressing the swab against the inside wall of the tube with a rolling motion.
- Hold swab at an approximate 30° angle from the sampling surface, taking care not to contaminate any part of the swab or the sampling site.
- Using firm, even pressure move the swab slowly and thoroughly over the entire sampling area, rewetting the swab tip with the Neutralizing Solution as needed. First horizontally, then vertically:
- After sampling is complete, carefully put swab back into vial and close cap tight.
- Label the sample using a permanent ink marker.
- Keep sample(s) at a refrigerated temperature (1 C to 4 C) until it is submitted to the laboratory for analysis.
Submit within 24 hours of sampling. (see shipping)
