2. Using a 4X4 gauze or tissue, slowly remove the stopper by easing the stopper up and away from you and taking care not to agitate the tube and disturb or mix the cells into the serum/plasma. 3. Using a transfer pipette, transfer the serum/plasma from the original tube into the labeled transfer (aliquot) tube. Do not get to close to the red cells at the bottom. 4. Centrifuge the transfer (aliquot) tube. 5.
Types. THHN wires come in two basic formats -- stranded and solid core. As a stranded cable, THHN is available in sizes from 14 awg to 750 kcmiL, and as a solid cable in sizes 14 to 10 awg.It is generally manufactured in copper or aluminum.ave. Window framed with wires & tube image by diter from Fotolia.com. THHN stands for thermoplastic high heat-resistant nylon coated. This is a type of insulated electrical wire suitable for a variety of low-to mid-voltage applications and can safely handle a load of up to 600 volts.
THWN wire refers to a specific type of insulation material, temperature rating, and condition of use for electrical wire and cable. It is the most common type of electrical wire due to its use as a single conductor wire while also being used in most electrical cables.The conductors are used in commercial and industrial applications specified in the National Electrical Code.HWN wire is often used in alternating current electrical distribution systems of many different types of buildings in North America. This is usually at voltage levels of 110-600 volts. Aluminum and copper conductors, sold as stranded or solid, use THWN insulation.
