- Q: Can plastic tubes be used for bottling medications?
- Yes, plastic tubes can be used for bottling medications.
- Q: Are plastic tubes suitable for display racks?
- Yes, plastic tubes can be suitable for display racks. They are lightweight, durable, and versatile, making them ideal for showcasing various products or materials in a visually appealing way. Additionally, plastic tubes can be easily customized and are available in different sizes, colors, and styles, allowing for creativity and flexibility in designing display racks.
- Q: what is dialysis tubing? how can it be used to demonstrate osmosis?
- Dialysis tubing is actually a semi-permeable membrane when used in water. Experiments illustrating osmosis and pressure gradients across a membrane use dialysis tubing. This tubing usually comes in rolls and when wet, will open up into a cylindrical tube that can be tied off at the ends. The tubing can also be fitted over a thistle tube for such experiments. Dialysis tubing is literally a semi-permeable sheet of plastic. [Like a cell membrane, it can allow certain things in, but not everything.] In a dialysis tubing experiment, one fills the inside of the sheet with a concentrated liquid of some sort and then seals off the open ends of the tube. Then, one places the tube and liquid into another type of liquid and after awhile, the liquid from the outside moves inside the tube. What I did for my first dialysis tubing experiment was filling the inside of the tube with a concentrated starch solution and placed the tubing into a beaker of Lugol's solution diluted with distilled water. After a 1/2 hr, some of the Lugol's and distilled water will have entered the dialysis tubing. One can see that osmosis has happened because the Lugol's in the tube would have turned blue when in contact with the starch. Osmosis caused the diluted/unconcentrated solution of Lugol's and dH2O to go through the semi permeable membrane and into the concentrated solution of starch. Like a cell's membrane, if the outside of the cell is more concentrated, the cell would lose water because the the water will leave the cell and go for the concentrated outside environment. If the inside of the cell was more concentrated than the outside, the outside water will go into the cell through the semipermeable membrane.
- Q: Can I use a plastic tube instead of a gas pipe?
- Simple answer: plastic PVC pipes do not only use the hot water pipes, hot melt pipe can PE polyethylene plastic, a plastic base, a plastic bag film is PE
- Q: where can i get a print out of all the clored tubes and what test is used for each tube for a phlebotomists ?
- Blood collection tubes must be drawn in a specific order to avoid cross-contamination of additives between tubes. The recommended order of draw for plastic vacutainer tubes is: First - blood culture bottle or tube (yellow or yellow-black top) Second - coagulation tube (light blue top). If just a routine coagulation assay is the only test ordered, then a single light blue top tube may be drawn. If there is a concern regarding contamination by tissue fluids or thromboplastins, then one may draw a non-additive tube first, and then the light blue top tube. Third - non-additive tube (red top) Last draw - additive tubes in this order: SST (red-gray or gold top). Contains a gel separator and clot activator. Sodium heparin (dark green top) PST (light green top). Contains lithium heparin anticoagulant and a gel separator. EDTA (lavender top) ACDA or ACDB (pale yellow top). Contains acid citrate dextrose. Oxalate/fluoride (light gray top)
- Q: Is it OK to drink water with plastic pipes at high temperature?
- From the point of view of hygiene, as long as the plastic tube is clean, there is no problem. But from a safe point of view. If the plastic pipe is a straw used for common drink, it belongs to normal temperature and is safe.
- Q: What diameters are available for plastic tubes?
- The diameters available for plastic tubes vary depending on the manufacturer and type of plastic used, but they typically range from as small as 1/8 inch to as large as 12 inches or more.
- Q: Two identical strong magnets are dropped simultaneously by two students into two vertical tubes of the same dimensions (see figure below). One tube is made of copper, and the other is made of plastic.
- The magnet dropped through the plastic tube. Plastic doesn't conduct electric currents with anywhere near the ability of the copper tube. The magnet dropped through the copper tube will induce a voltage around the loop as per Faraday's law of induction. Such a voltage creates a current through the tube, and that current makes this copper tube act as an electromagnet. This electromagnet will apply a force to the magnet which opposes the gravitational force on the magnet. How do I know it will oppose? Because of conservation of energy. In order for the current dissipating heat in the copper tube (due to the voltage and current combination), the magnetic force MUST do negative work on the falling magnet, such that the magnet does work on the tube as it falls.
- Q: i am designing something that has a frame of tubing that its relaxed when there is no air pressure in it, but becomes straight and reletivley rigid when when you put air presure in it.
- The 2 foot diameter nylon sleeves filled with low pressure air that you see for advertising displays. If you try to use small diameter tubing, with flexible plastic tubing, it won't work. The closest tubing that does work is specially made for pressure gauges, and it just slightly uncoils under pressure.
- Q: What are the different closure options for twist-off tubes?
- The different closure options for twist-off tubes include screw caps, flip-top caps, snap-on caps, and squeeze caps.
