Recommended Containers, Preservation, Storage, & Holding Recommended Containers, Preservation, Storage & Holding Times Revised July 29, 2016 Page 1 of 8 Recommended Containers, Preservation, Storage, & Holding Times Sample Integrity Eurofins Spectrum Analytical, Inc. is committed to maintaining the integrity of all samples submitted for laboratory analyses. Spectrum has a set criterion that all samples must pass in order to be considered to be of satisfactory condition. The Sample Department will notify the client of any samples that may be considered to be of unsatisfactory condition. Analysis of unsatisfactory samples will be conducted only with the written authorization from the client. Collection of Samples in Duplicate The collection of a sample in duplicate is requested when submitting a series of five or more samples per Chain of Custody. Collecting double the volume of a sample will enable us to perform additional quality control procedures in the laboratory. This practice may also be utilized when submitting samples for a project requiring additional quality control information. Cooling of Samples Samples must be chilled to <6oC immediately following collection and packed with a sufficient amount of ice to maintain that temperature until receipt at laboratory facility. EPA protocols do not allow the use of icepacks or ice substitutes (blue ice) because they are unable to maintain a cold enough temperature. Where “Cool ≤60 C” is stated, samples are not to be frozen. Drinking water samples must also include a temperature blank in the cooler. Laboratories are required to maintain a record of sample temperature as received. Spectrum utilizes infrared temperature recorder to monitor temperature, with the exception of temperature blanks which are measured by immersion thermometer. A notation of the temperature is made on the Chain of Custody. Samples received on ice will be noted as such.

  • How to Make a Smell Training Kit July 3 2019
    Some frequently asked questions Q. How much oil do I need in the jar? A. You only need enough to saturate the paper disc. Any more than that is just a waste of the oil. Q. I can’t smell anything! Have I done it wrong? A. Probably not. If you’ve followed the directions, your jars should be plenty “smelly”. The saturated disc, kept in the closed space with the cap on the jar, creates a really strong smell. If you are not smelling it now, give it time. Q. Can I put my nose all the way into the jar? A. That is not recommended. Keep the tip of your nose out of the jar. Q. What if I want to reuse the jar, but with different oils? A. You can do this, but you need to give the jars a really Smell Training Kits good clean with hot water and soap. Let them dry thoroughly. The lid will smell like the previous oil (not great, but you could improvise and remove the inside of the cap, which is made of white, plastic coated paper). Then cut yourself some new watercolour paper discs and make up the new jars. How to make your own Q. Can I use cotton pads inside the jars? A. Cotton pads are not recommended. They make a great place for bacteria to collect. Watercolour paper is absorbent, but does not harbour bacteria.

  • Leyden Jars and Batteries According to Benjamin Franklin
    eRittenhouse The Art of Making Leyden Jars and Batteries According to Benjamin Franklin Sara J. Schechner David P. Wheatland Curator of the Collection of Historical Scientific Instruments Department of the History of Science, Harvard University [email protected] Abstract The Leyden jar was arguably the most important instrument for electrical experiments in the second half of the 18th century, and Benjamin Franklin’s fame as a natural philosopher was based largely on his explanation of how it worked. In two remarkable letters written in the 1750s to scholars in Boston, Franklin offers instruction on the making of Leyden jars and assembling them into batteries. The letters also illustrate the challenges of getting and maintaining natural philosophical apparatus in colonial America, and a culture of recycling goods in order to make do. In the 1750s, Benjamin Franklin sent supplies and instructions for making Leyden jars to James Bowdoin, a Boston merchant and statesman interested in natural philosophy,1 and to John Winthrop, Hollis Professor of Mathematics and Natural Philosophy at Harvard College. Given the importance of Leyden jars to the development of Franklin’s own electrical theory, we are curious to know how Franklin made his own and what his recommendations might have been. The letters also illustrate the culture of repurposing goods and bricolage that was part of early modern science, particularly in the American colonies.2 1 James Bowdoin (1726-1790) was elected to the Massachusetts House of Representatives in 1753 and in 1757 began decades of service in the Council. His later leadership positions included governorship of the Commonwealth of Massachusetts in 1785-1787.

  • Bee Prepared by Making Meals in a Jar for Your Food Storage
    Bee Prepared by making Meals in a Jar for your food storage Copyright: Please do not reproduce this lesson and give it to other people. Direct them to www.homemakingdivas.com to purchase their copy or you can contact Stacy [email protected] ©www.homemakingdivas.com Meals in a jar are easy to cook. The ingredients are already cut up and measured so when you get ready to make the meal you only have a few steps to prepare the meal. Most recipes just need water added at cooking time. The size of the jar is versatile and can be made for the number of servings in your household. The quart size meals in a jar makes a meal for a family of 5-6 and averages about 9 cups of prepared food. The meals can be made in Mylar bags, but canning jars are preferable because the jar is reusable. When canning jars in a hot water bath you need to buy a new lid every time you bottle food but making a meal in a jar is different. You need a new lid the first time you make a meal but that lid can be reused later. Mylar bags are good to send with college students or friends that will throw away the jar. The pint sized meals in a jar are perfect for a single person or a couple. The hardest part about cooking after your family leaves home is all the leftover food. The pint size meal makes 2-3 servings so you won’t get tired of the food.

  • Steps in Processing Jams and Jellies
    Steps in Processing Jams and Jellies Follow These Steps in Making Jam or Jelly at Home (for recipes suitable for boiling water canning): 1. Wash Mason-type canning jars (half-pint or pint size) in hot water with detergent and rinse well by hand, or wash in a dishwasher. If your recipe calls for pre-sterilized jars, sterilize the clean jars by submerging them 10 minutes in boiling water. The easiest way is to stand the empty jars upright on a rack in a boiling water canner filled with clean water. There should be enough water to fill the jars and still come to a level 1 to 2 inches above the tops of the jars. Bring the water to a boil and boil for 10 minutes. (If you are at an altitude of 1000 feet or more, add 1 minute of sterilizing time for each 1000 feet of altitude.) Jars can remain in the hot water until they are ready to be filled. If you are not pre-sterilizing jars, keep the clean (washed and rinsed) jars hot until time to fill them. 2. Prepare the canning jar lids according to the manufacturer's recommendations. 3. Prepare the jam or jelly according to recipe directions. Boil for the recommended time in the recipe and then quickly skim off foam (if needed or desired). 4. Remove presterilized jars from the hot water one at a time, carefully tilting them to quickly empty the water from them into the canner. Be careful not to burn yourself. To make sure they are completely drained, the jars may be turned upside down on a clean towel on the countertop.
