2. Vacutainer - Wikipedia

   en.wikipedia.org/wiki/Vacutainer

   Vacutainer. A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing.

3. Tygon tubing - Wikipedia

   en.wikipedia.org/wiki/Tygon_Tubing

   Tygon LFL (Long Flex Life) pump tubing is non-toxic clear tubing with broad chemical resistance. [ citation needed ] It is often used in product filtration and fermentation and surfactant delivery. Tygon 2275 High Purity Tubing is a plasticizer-free material that is often used in sterile filling and dispensing systems and diagnostic equipment.

4. Linear low-density polyethylene - Wikipedia

   en.wikipedia.org/.../Linear_low-density_polyethylene

   Linear low-density polyethylene (LLDPE) is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins. Linear low-density polyethylene differs structurally from conventional low-density polyethylene (LDPE) because of the absence of long chain ...

5. Serum-separating tube - Wikipedia

   en.wikipedia.org/wiki/Serum-separating_tube

   These tubes should be used with care when measuring drug or hormone levels because the drug or hormone may diffuse from the serum into the gel, causing a reduction in measured level. The gel in SST II tubes (which appears slightly less opaque) is supposed [weasel words] to have less effect on drug levels in serum. [citation needed]

6. High-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/High-density_polyethylene

   High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. [1] With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and ...

7. Polyethylene terephthalate - Wikipedia

   en.wikipedia.org/wiki/Polyethylene_terephthalate

   Polyethylene terephthalate (or poly (ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins.
