Description Spectrophotometer
The spectrophotometer is ideal for the rapid and reliable quantification of dsDNA, ssDNA, RNA, and, proteins. Additionally, the device is ideal for determining sample purity using the 260/280nm purity method. This handy measuring device with small and compact dimensions will fit easily into today’s crowded lab space. By combining a large LCD screen with an ergonomically designed keypad, any untrained personnel will be able to use the Nucleic Acid Meter immediately out of the box. Taking measurements is as simply as plugging in the AQ-07 then selecting a method from the home screen.
The decice is preprogrammed with methods for:
- Purity via 260/280nm ratio
- ssDNA via 260nm
- dsDNA via 260
- RNA via 260nm
- Protein via 280nm
Unlike other spectrophotometers used for the quantification of DNA, RNA, and protein, the AQ-07 uses light emitting diodes (LED). The spectrophotometer uses a 260nm LED for measuring ssDNA, dsDNA, and RNA. For the quantitation of protein, a 280nm LED is used. When taking purity measurements requiring the 260/280 method, both LEDs are utilized. The value of using LEDs for these methods include; long lifetime without the need for replacement, low heat production shielding samples from degradation, and high photometric precision. The spectrophotometer has a reading range from 0.0 to 4.3 OD allowing measurements of less than 1ug/mL ds DNA.
Cuvettes
At times when working with DNA or RNA, for instance one difficulty is that only very small amounts of sample 
are available for photometric measurements in biochemical analysis. Additionally, such samples often have a very low specific absorption and the light path cannot be reduced beyond a certain point. GeneON offers two different types of cuvettes to overcome these challenges.
Cuvette I (8µl)
This Ultra-MicroCuvette was custom designed for measurements using 8ul or more of sample. The top section is constructed so that capillary action is prevented when pipetting sample into the micro cell. Due to this custom design only 8 μI of sample is required. By retaining a pathlength of 3 mm, sensitivity has not be compromised. This cell is constructed so that filling and emptying can easily be accomplished with commonly available pipette tips.
How it works?
- pipette 8µl or more sample into slotted sample compartmen
(Sample will reside in small retangular quartz window allowing
light to pass through sample)
- measurment in the Nuleic acid meter
- remove sample with tip
- wash with ethanol of water
- use again
Cuvette II (150µl)
This Micro-Cuvette is available for labs that would like to measure samples volumes of 150ul and greater. It has frosted walls and a lid, measurements of 150ul are made simple. The dimensions are 25mm x 12.5mm x 12.5mm.
Both cuvettes fits to the device, without any adapter.
