When it is necessary to protect a sample from light, the Whirl-Pak® black bag is specially designed for this application. The polyethylene film is made from pigmented resins so the black color is an integral part of the bag and not a printed layer. The result is an opaque bag providing maximum protection for samples that are sensitive to light. It is ideal for pharmaceuticals, seasonings, flavors, food supplements, vitamins, marine life, and many other liquid or solid products. It is FDA approved for food contact.
The white, write-on strip makes sample identification easier and more convenient. It’s easy to write on this white strip using an ordinary ballpoint pen, pencil, or felt-tip marker. The paper-like finish virtually eliminates ink smearing, and provides a surface that will accept a variety of writing instruments.
Capacity is measured in fluid ounces when the bag is closed and tab is folded over three times. Volume and dimensions are approximate; bags should not be used at temperatures above 180° F （82° C）. Bags can be frozen to any temperature, even liquid nitrogen – careful handling required after freezing. All bags are sterilized after manufacturing.

Nasco WHIRL-PAK Coli-Test Bag，Product Number: B01417WA

Coli-Test bag for color-changing reagents.
100 ml capacity
3" W x 7-1/4" L （7.5 x 18.5 cm）
2.5 mil （.064 mm） thick
Box of 100
If water samples are being tested with color-changing reagents, this bag can be used in place of the expensive bottle currently used. The bag is made of a special barrier film suitable for use with enzyme-based methods that result in a chromogen and/or a fluorogen release when total coliform and E. coli are present. The special film prevents color change from permeating through the bag, contaminating another sample and creating a false positive, and making contact with a person’s skin if they are not wearing gloves. It is sterile, contains 10 mg of active sodium thiosulfate to neutralize chlorine, has 4 oz. and 100 ml fill lines, and is compley self-standing – no rack or holder is needed to keep the bag upright. If the sample is not chlorinated, this bag can still be used; the sodium thiosulfate will not affect the sample, it is nontoxic and nonnutritive, and only neutralizes chlorine if present. A free color comparator is included in every box.
The Coli-Test bag has been accepted by the EPA and is listed in the EPA Manual for the Certification of Laboratories Analyzing Drinking Water Section 5.3.1.4, 5th edition, January 2005.
The Coli-Test bag will save money three ways: less expensive than the bottle, lower freight charges, and reduced disposal costs. A box containing 100 bags measures 9" x 7" x 2" （23 x 18 x 5 cm）, weighs 1 lb. （0.40 kg）, compared to a box of bottles which has considerable more volume and weight.

Product Number: B01300WA

18 oz. （532 ml） capacity
4-1/2" W x 9" L （11.5 x 23 cm）
2.5 mil （.064 mm） thick
Barrier film
Box of 500
For long-term storage （up to two years）, the Whirl-Pak® Retain Bag will protect the sample and save money and space.
• Made from a barrier film of polyethylene and polyester
• Has extremely low permeability for oxygen and moisture
The result is that sample integrity will be maintained during storage for both liquids and solids. These bags are sterilized with radiation, because gas sterilization will not penetrate this film. If a sample is going to be tested periodically, closing the bag in the regular manner will be sufficient. However, if the bag will be kept closed for an extended period, then a heat sealer can be used to give the bag a permanent seal.
Capacity is measured in fluid ounces when the bag is closed and tab is folded over three times. Volume and dimensions are approximate; bags should not be used at temperatures above 180° F （82° C）. Bags can be frozen to any temperature, even liquid nitrogen – careful handling required after freezing. All bags are sterilized after manufacturing
