Choices of Cleaning Processes for Pre-Cleaned Containers

All pre-cleaned containers are supplied with caps attached. We offer a wide variety of bottle and closure combinations. Please contact us for more information on the bottle/closure/cleaning service combination best suited to your application and for part numbers.

KaptClean® Environmental Containers

All of our KaptClean containers are available Cleaned & Certified or Cleaned only. Certificate of Analysis provides a lot and stock number and meets or exceeds specifications.

Cleaned for Semi-Volatiles - Glass sample containers cleaned for semi-volatiles, pesticides, PCB’s and metals.

Clean for Volatiles - Sample containers for use in volatile organic analysis.

Cleaned for Metals - KaptClean HDPE sample containers cleaned for metals meets or exceeds analyte specifications.

Kapt - Ready to Clean - Ready to Clean bottles are designed for users who prefer to use their own cleaning process. Ready to Clean bottles are fully assembled with polypropylene caps and a friction fit .015" PTFE disc. Both cap and liner can be washed, heated or autoclaved depending upon your application. The PTFE disc is chemically inert and will not interfere with your test results.

Premium Cleaning Processes

Cleaned for TOC - These containers are cleaned for Total Organic Carbons to <20ppb or <10ppb, depending on customer requirements.

Super Clean/Cleaned for Oil Analysis - Super cleaned containers are typically used by companies that operate large machinery, which require the oil to undergo various analytical analyses for environmental compliance and/or for routine maintenance of the machinery. Super Clean Bottles are cleaned according to Qorpak QC procedures and meet or exceed the following specification: Less than 10 particles in the greater than 10 micron size per ML.

Ultra Cleaned containers feature a proprietary cleaning process that removes up to 99.5% of particles that are 5 microns and larger. Designed for those needing containers cleaned for general lab use or fluid sampling. The typical cleanliness level for containers less than 100ml is less than 200 particles per container that are larger than 5 microns. For larger containers, the typical cleanliness level is less than 2 particles/ml that are larger than 5 microns. Containers are quality controlled and process certified.

PLEASE NOTE: Containers are designed only for general laboratory and industrial fluid sampling applications where particulate cleanliness of the container is required. Containers are not designed for use in pharmaceutical, medical device, chemical packaging, or manufacturing applications due to consideration of other requirements that may affect their suitability for use. For cleaned containers for pharmaceutical, medical device, chemical packaging, or manufacturing applications, or for containers that require a certification of analysis or adherence to cGMP quality requirements, please inquire about our custom cleaned containers.


Vacuum & Ionization

The Vacuum and Ionization process removes contaminants such as loose dirt, carton lint, aerosols, and fine glass particles.

V & I Cleaning Process:
1) Compressed air passes through a condensate separator and coalescing filter to remove aerosols and fine dust particles.
2) Next, the air passes through an absorbent filter to remove gases.
3) A vacuum draws the particulate-laden atmosphere out of the container.
4) Individually cleaned closures are immediately placed on the container.

Benefits of V & I:

  • Is extremely cost-effective
  • Saves time! No need to waste valuable time rewashing bottles
  • Provides a clean final appearance
  • You will not find any dust particles floating in your samples
  • Seals cleanliness into each individual bottle. Since each container is individually cleaned, they will not collect dust, flies, and other debris while stored in your lab
  • Odor-free and tasteless. The air inside the bottle will not interfere with your product in any way.
