Ultra Clean 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
environmental sample containers VOA vials for analysis purging instrument capture USA National Field Manual for the Collection of Water-Quality USEPA Method 445 for chlorophyll (CHL) analysis stipulates a holding time of 24.5 days from the time of sample collection for frozen samples.
Add 25 mg of ascorbic acid to sample vials before filling. After the vial is filled to overflow, then add one to two drops of 1:1 HCl for each 20 ml of sample volume to a pH of <2. Seal the vial taking care not to trap any air bubbles. Turn vial septa-face down, and shake vigorously for 1 minute. Collect samples in duplicate 40ml VOA vials. EPA
To obtain clean containers or clean vials, rigorous mechanical, chemical, or other cleaning procedures must be employed. Kaptclean™ is the Qorpak line of environmentally pre-cleaned containers. These products are used for environmental sampling applications (testing for Elements or Analytes).

Mailer guarantees sample integrity For use with 9853Q01 and Q02 Sample Containers Sturdy foam protects water samples during transport for coliform testing Rib structure holds 100 mL vials tightly in place Lightweight, reusable and recyclable Cavity dimensions: 3-3/4 x 2-1/4.
Methods 504.1, 505, 531.1 and 547 – Additional Organic Compounds in VOA vials • These vials each have a specific dechlorinating agent. Fill as above for ZERO HEADSPACE ensuring that you do not overflow. • Replace the vial cap securely. Invert the vial to verify that there are no air bubbles greater than pea-size.
EPA Vial 20ml. Level 3. Amber borosilicate glass. 24-414 fluoropolymer resin/silicone-lined open-top cap. Septa: .125 For volatiles. Bottles meet EPA guidelines for sample container material component specifications. Includes seals. Certificates of Analysis available by request. 3.65. $87.34. 339-20C. EPA Vial 20ml. Level 3.
These Volatile Organic Analysis (VOA) containers are pre-cleaned and certified to meet strict EPA requirements. Made of clear borosilicate glass, vials have a 0.125''-thick, I-CHEM blue, PTFE/silicone septa and open-top
Sample Size: 40 mL: Sample Container: VOA vial with fluoropolymer-lined cap Use of "certified clean" containers is preferred. Otherwise, use glassware cleaning instructions found in Chapter 3 of SW-846. Rinse with detergent, followed by tap water, 1:1 nitric acid:tap water, 1:1 hydrochloric acid:tap water, and reagent water.
Standard 40-mL glass screw-cap VOA vials with PTFE-lined silicone septa may be used for liquid matrices. Special 40-mL VOA vials for purge-and-trap of solid samples are described in Method 5035. VOA vials for headspace analysis of solid samples are described in Method 5021. Standard 125-mL wide-mouth glass containers may be used
for sample preparation and analysis in the laboratory. Use of these containers for sampling helps minimize loss of VOCs resulting from opening sample containers and/or transferring materials from one container to another. Certified pre-cleaned VOA vials are commonly used as sample containers for VOCs and are
Sample Containers * For each type of sample and each analytical parameter, list the type, grade, quantity and size of the containers re- quired; this information can be included in a table, such as the table discussed in section V. * Appendix C identifies the containers and volumes which are used in the CLP program.
