It is much more accurate to make several smaller stepwise dilutions to reach a final concentration when the required reduction in concentration is large. Clearly, accurate pipetting during preparation of serial dilutions is critical, because any deviation will propagate to all of the subsequent steps.
Serial Vs Parallel Dilution Method. See also SIMPLE DILUTION 2. There are two problems with this series of. Many laboratory protocols require the serial dilution of reagents or compounds. If the dilution. 3 uL = 297 uL diluent to perform the 1:100 dilution.

The dilution factor chosen for the series of calibration standards is achievable by using serial dilution. The progression of calibration standard concentration is always a geometric series. Consider the example of making the first standard at 1/3 the concentration of the known, the next calibrant would be 1/9th the concentration of the known.

Simply so, what are the advantages of serial dilution?
Serial dilution has many advantages: the materials necessary are typically already present in the lab and require no special engineering. Conditions can be adjusted as the experiment progresses (e.g., drug concentrations increased as drug resistance improves).
Similarly, what is serial dilution and why is it used? Serial dilution is the stepwise dilution of a substance in solution. Serial dilutions are used to accurately create highly diluted solutions as well as solutions for experiments resulting in concentration curves with a logarithmic scale.
Consequently, is direct or serial dilution more accurate?
The direct dilution method uses far less sample than the serial dilution method. This figure shows only the first four concentrations via direct dilution. Essential to direct dilution is the ability to accurately transfer extremely small volumes of stock solution, which is generally not possible with pipets.
What is the advantage of performing a serial dilution instead of a single dilution?
Easier and Faster Preparation of Calibration StandardsThe errors introduced with each successive dilution drops proportionately with the solution concentration. Preparing a series of calibration standards by this method reduces the amount of required time.

Contents • • • • Parallel Data [ ] The parallel port on modern computer systems is an example of a parallel communications connection. The parallel port has 8 data wires, and a large series of ground wires and control wires. IDE hard-disk connectors and PCI expansion ports are another good example of parallel connections in a computer system. Serial Data [ ] The serial port on modern computers is a good example of serial communications. Serial ports have either a single data wire, or a single differential pair, and the remainder of the wires are either ground or control signals. USB, FireWire, SATA and PCI Express are good examples of other serial communications standards in modern computers.

Which is Better? [ ] It is a natural question to ask which one of the two transmission methods is better.
At first glance, it would seem that parallel ports should be able to send data much faster than serial ports. Logitech Mk300 Driver Vista more. Let's say we have a parallel connection with 8 data wires, and a serial connection with a single data wire.
Simple arithmetic seems to show that the parallel system can transmit 8 times as fast as the serial system. However, parallel ports suffer extremely from inter-symbol interference (ISI) and noise, and therefore the data can be corrupted over long distances. Also, because the wires in a parallel system have small amounts of capacitance and mutual inductance, the bandwidth of parallel wires is much lower than the bandwidth of serial wires. We all know by now that an increased bandwidth leads to a better bit rate.
Serial And Parallel Dilution
We also know that less noise in the channel means we can successfully transmit data reliably with a higher Signal-to-Noise Ratio, SNR. If, however, we bump up the power in a serial connection by using a differential signal with 2 wires (one with a positive voltage, and one with a negative voltage), we can use the same amount of power, have twice the SNR, and reach an even higher bitrate without suffering the effects of noise. USB cables, for instance, use shielded, differential serial communications, and the USB 2.0 standard is capable of data transmission rates of 480Mbits/sec! In addition, because of the increased potential for noise and interference, parallel wires need to be far shorter than serial wires. Consider the standard parallel port wire to connect the PC to a printer: those wires are between 3 and 4 feet long, and the longest commercially available is typically 25 meter(75 feet). Now consider Ethernet wires (which are serial, and typically unshielded twisted pair): they can be bought in lengths of 100 meters (300 feet), and a 300 meters (900 feet) run is not uncommon!
UART, USART [ ] A Universal Asynchronous Receiver/Transmitter (UART) peripheral is used in embedded systems to convert bytes of data to bit strings which may be transmitted asynchronously using a serial protocol like RS-232. A Universal Synchronous/Asynchronous Receiver/Transmitter (USART) peripheral is just like a UART peripheral, except there is also a provision for synchronous transmission by means of a clock signal which is generated by the transmitter.
Serial Dilution Vs Parallel Dilution
• On the use of the serial dilution culture method to enumerate viable phytoplankton in natural communities of plankton subjected to ballast water treatment • There are two situations where serial dilutions should be used rather than parallel dilutions: FIRST: Use a serial dilution when you need several solutions of the same solute and there is a constant dilution factor. Therefore, this series has a constant dilution factor of 10. • THE INDICATOR DILUTION METHOD: ASSUMPTIONS AND APPLICATIONS TO BRAIN UPTAKE Olaf B. Paulson and Marianne M.
