Such systems are characterized by the number of manipulating XYZ arms, including septum-piercing devices, the number of syringe pumps and volume of syringes, the number of valves and their way actuation, the number of independent system fluids and the size and numbers of docking platforms for reaction blocks. 

If the ultimate in protection is required, a membrane of metal less than 0.1 mm thick is left across the nozzle face and provides visible tamper-evidence. Sometimes a special double-ended cap is used, incorporating an integral piercing device. The tube is pierced by removing the cap, reversing it and screwing it back onto the tube until the inverted cone pierces the membrane. If the product is of the unit dose type a membrane tube is used without a cap or threaded portion, e.g. taper or torpedo ended tubes. In this case piercing of the nozzle must be carried out with a pin or similar device. Alternatively a break-off style tip can be used. 

The gauge is connected to a piercing device with a hollow steel spike. The CO2 may be collected in an absorption burette containing 15 % sodium hydroxide thus allowing measurement of the residual air. 

The vapor pressure of a molten metal can be measured with a device called a Knudsen cell. This is a container closed across the top by a thin foil pierced by a small, measured hole. The cell is heated in a vacuum, until the vapor above the melt streams from the small hole (it effuses). The weight of the material escaping per second tells the rate at which gaseous atoms leave. 

In 1948 William Bradford Shockley (1910-1989), who is considered the inventor of the transistor, and his associates at Bell Research Laboratories, Walter Houser Brattain (1902-1987) and John Bardeen (1908-1991), discovered that a crystal of germanium could act as a semiconductor of electricity. This unique property of germanium indicated to them that it could be used as both a rectifier and an amplifier to replace the old glass vacuum tubes in radios. Their friend John Robinson Pierce (1910-2002) gave this new solid-state device the name transistor, since the device had to overcome some resistance when a current of electricity passed through it. Shockley, Brattain, and Bardeen all shared the 1956 Nobel Prize in Physics.

The Gun Control Act of 1968 requires that firearms and ammunition manufacturers obtain a federal license and pay a fee of 50 per year for firearms manufacturers and 10 per year for ammunition makers unless the manufacturer makes destructive devices or armor-piercing ammunition, in which case the fee is 1,000 per year.

The measurement of carbonation is carried out using a device similar to that shown as Figure 7.4. It consists of a jig in which the container can be restrained, and a piercer attached to a pressure gauge. The container is placed in the jig, and is first of all pierced and, then shaken before the pressure is measured. The release valve is opened until the pressure gauge reads zero and all the gas has been exhausted from the container headspace. The release valve is then closed and the container shaken again. The pressure is re-taken. The container is released from the jig and the temperature of the contents measured. A carbonation chart is then used to determine the volumes of carbonation. 

Spinhaler uses two perforating pins to puncture the capsule body for opening. To feed the capsule, the patient has to unscrew the device body and push the capsule into a cup that is connected with a vertical spindle holding a propeller. After closing, the capsule is pierced by sliding the outer sleeve down and back again. When the patient tilts his or her... 

Further improvement of this principle of factory-metered blistered unit doses was achieved when GlaxoSmithKline developed the Accuhaler device (also named Diskus in some countries (Fig. 8.7). This multiple-dose DPI device contains a blister strip of 60 unit doses that is transported to the next filled unit dose by pulling a small ergonomic lever prior to inhalation. The powder is presented for aerosolization by peeling back the foil from the blister, which is superior to simple piercing because it is not associated with variability in foil flap shape and device retention. The dose indicator on top of the device tells the patient how many doses are left and decreases each time the lever is pulled. This means that as with most other devices, operation of the dose indicator is associated with the loading operation and not with the inhalation maneuver. 

Ready-made Sephadex G-25 columns are available for use with gravity feed (PD-10) or syringe (HiTrap) from Amersham Biosciences. The PD-10 columns with a bed volume of approx 9 mL are very suitable for processing samples of 1-2 mL. Similar cross-linked dex-tran devices, Presto and Kwik columns, are available from Pierce (Rockford, IL). 

The Diskhaler, also a multi-dose system, employs individual doses contained within blisters on a disk. On actuation, a needle pierces the upper and lower surfaces of one of the blisters. As the patient inhales, the contents of the blister are dispersed into the airstream, the dmg particles dissociate from the carrier and a fraction is delivered to the lung. On re-priming the device, the disk rotates to expose the next blister to the piercing needle. 

There are three basic types of intravenous administration 1) primary set 2) secondary set and 3) a volume control set (Fig. The basic components of all these sets include a piercing spike (to insert into the bag or bottle), drip chamber and drip orifice, tubing ranging in length from 160 to 250 cm (63-98.58 in.), a roller clamp or other flow control device on the tubing.
