ProScale 333 Digital Pocket ScaleThis digital scale has a blue, backlit display to help you see your weight readings, even in dim lighting. Comes factory calibrated and ready to use along with easy to follow calibration instructions.This tiny scale's hard protective cover is great for keeping your scale safe when you aren't using it and it doubles as a nice expansion tray, increasing the area you have to weigh your stuff on. Since it has edges, you can weigh all kinds of things that would normally fall right off the platform. The tare button on the front can be pressed to "zero out" the weight on the scale. You can then add more weight, and the display will only show the weight of the items you're adding. This is useful when you want to use the cover as an expansion tray to weigh your things, or if you want to get separate weights of multiple items.Included with this mini scale is a VibraKill® Pad to keep vibrations, (caused by everyday items like your fridge, nearby music, your washing machine, etc...) from messing up your weighing.You won't have to worry about this scale taking up space. It's just over three inches long, and less than an inch thick! You can take this scale pretty much anywhere you want...stick it in a pack, purse, or in your shirt pocket. The 333 will automatically turn off after a few moments of inactivity, saving battery power and money.5 YEAR MANUFACTURER'S WARRANTY!
QuickCheck Bloodstain GreenOur QuickCheck line of products has been so successful, we've expanded the line to encompass a blood detection kit as well! This kit contains 10 individual bloodstain tests that can immediately tell you whether or not a substance is blood. Simply moisten a sterile swab with distilled water and rub it across the suspected stain. Break both ampoules, agitate to mix, then drop one or two drops on your swab with the provided applicator. If the sample is blood, the swab will instantly turn a bright blue/green. Each kit includes a QuickCheck sleeve, swab and disposal bag. The recommended “use-by” date on this product is 3-6 months. In some cases the tests may last longer, depending on the storage conditions. When the product color has changed in the ampoules to a green tint, the test should no longer be used.$19.83 Add to cart
Hexagon OBTIHexagon OBTI is simple to use with results in less than three minutes. Human hemoglobin (hHb) reacts with the conjugate composed of blue particles and monoclonal anti-human hemoglobin antibodies. This screening test rapidly verifies if a bloodstain is human blood. Hexagon OBTI contains a two-part test: a collection tube for the blood sample and a test bar. Directions A sample of the presumed human blood trace is transferred into the tube with transport medium. With the lid screwed back on, shake the sample gently inside the transport medium. This mixture is added, drop by drop, to the test in the sample well (S) at the lower end of the test. A positive sample is typically detected within 2-3 minutes. Negative results should be confirmed after 10 minutes.Select options
