Silicon glass

For these reasons, the plastic tip, or the siliconed glass tip have been used for micro measurements. With a plastic tip, there is no limit to the size of the specimen which may be sanq>led. For example, it is possible to sample amounts of the order of nanoliters, provided one resorted to a micromanipulator. While the clinical chemist has not availed himself generally of this technique, the physiologist, has for many years, been measuring samples from within a single cell, or from perhaps, a renal tubule, so that the sample can then be subsequently analyzed. It awaits only an intelligent manufacturer to adapt the micromanipulator as a routine tool in the Pediatric... 

This may even lead to blockage owing to accumulation of corroded material in the tube. In [38] it is also claimed that steels are not suited for nitration however, since the grade of the steel employed is not given, it cannot be excluded that high-alloy steels may behave better. Silicon, glass and titanium are recommended materials [38].

As an example we present here some computation results for the plasma treatment of the hospital patients room waste with advantage of plastics, cellulose and non-organic metal and glass parts. To check the efficiency of gas fuel generation from this waste we have simulated the limited oxidation within temperature range 1000 - 2500 °C. We have assumed that in 1kg of dry waste are (by weight) 60% of plastics, 15% of silicon glass, and 10% of... 

Add 30 0 pL of probe containing hybridization solution to each tissue section treated with the in situ RT-PCR reaction protocol. Cover with siliconized glass coverslips, seal with rubber cement. 

Silicon glass is made by fusing pure quartz crystals or glass sand (impure crystals), and it is typically about 99.8% silicon dioxide. It is high-melting and difficult to fabricate.

Pipet 5-10 pi of Soln. A (4-7 MBq) into a 4-ml polystyrene or siliconized glass test tube. Then add 25 pi Soln. B, followed by 10 pi of protein solution (2-5 pg, dissolved in Soln. C), 10 pi Soln. D, and 100 pi Soln. E. Vortex after each addition. Fill up to 1 ml with Soln. G and count for total radioactivity. 

Early observations showed that blood clotted faster in clean glass tubes than in siliconized glass. When Mr. Hageman s blood failed to clot in vitro, it was speculated that a Hageman Factor was responsible for the in vitro activation of blood coagulation (see Ref. 2) for a delightful account).

An interface or housing for micro fluidic applications was designed and fabricated. The device, made of PEEK, allows facile non-permanent coupling of standard capillary tubing to silicon/glass micro mixer chips. No additional adhesive material was used to for a secure and tight interconnect [70],...

Microsystems can be built on various substrates with a range of materials crystalline silicon, amorphous silicon, glass, quartz, metals, and organic polymers. Single-crystal silicon substrates have been used in most areas of microfabrication for a range of excellent reasons ... 

Microstructures and systems are typically fabricated from rigid materials, such as crystalline silicon, amorphous silicon, glass, quartz, metals and organic polymers. Elastomeric materials can be used in applications where rigidity is a drawback. We have demonstrated the concepts of elastomeric systems by fabrication of photothermal detectors, optical modulators and light valves. We believe that elastomeric materials will find additional applications in the areas of optical systems, micro analytical systems, biomaterials and biosensors.

The absorption cell is a glass silicon glass sandwich component (15xlx 0.4 mm) where optical intensities from different colored LEDs are measured by a 64 pixel CCD detector, see also Fig. 25. A demonstrator system with a total system volume of about 50 ml is illustrated in Fig. 26.
