Description
Whirl-Pak® plastic bags with write-on strip, 12,5 x 7,5 cm (L x W), are sterile sample collection bags made from low-density polyethylene (LDPE). Measuring 125 mm in height and 75 mm in width, they are compact yet practical for liquid samples in food, water and wastewater testing as well as biological or chemical analyses. A write-on strip enables clear sample identification directly on the bag surface. The filling opening is reinforced on both sides with a metal wire tab that keeps the mouth open and taut during filling. For hermetic closure, the bag is held by the metal tabs and whirled several times around its own axis before the tab ends are folded over and pressed firmly. The Whirl-Pak® can be opened and resealed as often as required. Strong weld seams on all sides provide additional security against leakage. These bags from manufacturer neolab - Labor are supplied in packs of 100 pieces and suit everyday laboratory and field sampling where reliable sterile containment is needed.
This article is part of Vortex mixers, in Stirring, shaking & mixing.

Questions about Whirl Pak® plastic bag with label panel, 12.5 x 7.5 cm (L xB)
What is this article?
Whirl Pak® plastic bag with label panel, 12.5 x 7.5 cm (L xB) is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Vortex mixers, inside Stirring, shaking & mixing, in Lab instruments.
A vortex mixer oscillates a cup so a tube pressed into it spins its contents into a vortex. It mixes a tube in seconds. It does not mix a flask, and it is not a substitute for a shaker when the method says thirty minutes.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
