Chemical Preservatives

EP Preserved™ Containers

  • Chemical Preservation has become popular in the environmental sampling field. Since 1990 EP Scientific has provided this service with our EP Preserved Containers™ to simplify field preservation.
  • Level 1 Products include a certificate of analysis for the container and the added reagent.
  • Sometimes it can be confusing in deciding the amount of preservative to add to your containers. Although we can custom fill to your request, a list of our most common EP Preserved™ Containers may prove helpful.
  • EP Preserved™ containers provide an extra measure of assurance that proper sampling protocols are followed especially when collecting for a number of parameters.
