Background Over the years NAD has built up an enviable reputation for building fine CD players offering outstanding value for money. The latest model, the NAD 510 will further enhance that reputation. As always, sonic performance is the first priority at NAD. By deleting the remote control and many seldom used features, the NAD engineers could spend the money saved on design and engineering directly related to performance. Not surprisingly, as a direct result of this approach the sound quality belies the NAD 510's keen price. Behind the deceptive simple front panel lies sophisticated circuitry. Design As with all NAD CD players, particular attention has been paid to keep the analogue path free from RF interference (which can otherwise severely contaminate the purity of the audio signal). For a start, all circuitry not directly related to the sound itself (transport, servo's, display drivers, etc.) has been relegated to separate circuit boards. The audio section has its own dedicated PCB located directly behind the output socket, minimising the length of the signal path and physically keeping it removed from the other boards. Separate power regulators for the digital and analogue sections isolate the two electrically as well, and furthermore, careful lay-out of the PCB tracks around the Digital-to Analogue converter helps to contain any remaining RF. For the NAD 510 the much acclaimed Bitstream Digital-to-Analogue single bit converter chip was chosen for its excellent low level linearity. The output impedance is very low at 110 , making the NAD 510 less sensitive to cables or the ancillary equipment it is partnered with. Paired with a 5-pole filter in the analogue stage and using high grade components, the result is an unparalleled open, rich and detailed sound that is commonly only available from more expensive machines. The understated yet comprehensive display gives the listener all the vital information required to access and enjoy the selected music. The track number is displayed and for those who regularly transfer CDs to cassette tape, the button displays the current time elapsed or remaining for complete CDs or individual tracks. A "calendar" type section in the display gives immediate visual information how many tracks in total there are on the CD. RANDOM gives the listener a random selection of all tracks on the disc in play and REPEAT allows repeat playing of the disc or individual tracks. Individual tracks are easily accessed by SKIP (Forward and Back). SCAN (Forward and Back) gives an aural precis of individual tracks, giving the listener the opportunity to reach specific sections of the track. Anyone on a tight budget but interested in a high performance CD player without frills should put the NAD 510 at the top of their shortlist.

-Nicotinamide-adenine Dinucleotide (NAD) Nutrient Supplement
(for in vitro diagnostic use)

PRODUCT CODE PL.510

INTENDED USE Pro-Lab PL.510 NAD Supplement is an enrichment supplement for Haemophilus spp. and Neisseria gonorrhoeae. SUMMARY AND EXPLANATION The British Society for Antimicrobial Chemotherapy has issued guidelines recommending that media to be used for disc diffusion sensitivity testing for fastidious organisms, be supplemented. For the isolation of Haemophilus spp. and N. gonorrhoeae, Iso-Sensitest agar (Oxoid CM471) should be supplemented with 5% whole horse blood and 20 mg/L nicotinamide adenine dinucleotide (NAD)1. DESCRIPTION An a c c u rate q u a nt i t y o f - N i co t i n a m i d e - a d e n i n e Dinucleotide (NAD) is lyophilized and provided in individually labelled vials. Each vial is sufficient to supplement 1000 mls of prepared media. FORMULA Each vial contains: -Nicotinamide-adenine Dinucleotide PROCEDURE 1. To reconstitute each vial of Pro-Lab PL.510 NAD Supplement add, aseptically, 10 mls of sterile deionized water. After closing the vial, gently agitate to assist reconstitution. The solution should be clear and free from visible particulate matter. 2. Add the reconstituted contents of one vial of the NAD Supplement to 1000 mls of prepared media (Iso-Sensitest agar with 5% whole horse blood) at a temperature of 50C to 55C. Mix gently and pour into sterile petri dishes. 3. Overnight storage at 4C is recommended to allow suitable equilibration. For extended storage at 4C, eg. up to 7 days, plates should be contained in sealed plastic sleeves or similar packaging. 20.0 mg
IN USE 1. Before using the medium ensure that the surface of the plates are dry. Do not over dry plates. 2. Inoculate plates for disc diffusion sensitivity testing as per approved procedures. 3. Incubate plates at 37C in 4-6% CO 2 in air for 18 to 20 hours. 4. After incubation, measure zones of inhibition. SAFETY PRECAUTIONS 1. Pro-Lab PL.510 NAD Supplement is offered only as an in vitro material and is in no way intended for a curative or prophylactic purpose. 2. During and after use, handle all materials in a manner conforming to Good Laboratory Practices and consider at all times that material under test should be regarded as a potential biohazard if mishandled. PRESENTATION Pro-Lab PL.510 NAD Supplement is supplied 10 vials per box (lyophilized). STORAGE Pro-Lab PL.510 NAD Supplement must be stored at 2C to 8C. Kept under these conditions it may be used up to the date of expiry shown on the product label. REFERENCES 1. B r o w n , D.
