VersaWave

Faster Measurements

Using the VersaWave’s disposable, UV transparent tips eliminates the need to clean any equipment between or after measurements as is the case with some microvolume spectrophotometers. Additionally, most microvolume spectrophotometers such as the NanoDrop™ require precise pipetting of small volumes to place or recover sample which can be time consuming and result in sample loss. The VersaWave requires no tricky pipetting for sample measurement as the sample does not leave the tip, making it ideal for both newer and more experienced users. Intuitive software designed for touchscreens provides immediate access to frequently used measurement protocols, with dedicated modules for different applications. VersaWave’s high dynamic range means most samples do not need dilution, saving more time.

Versatility

The VersaWave provides full spectrum results in seconds with on screen gauges to indicate the level of purity for nucleic acid or protein samples. Data is easy to export to established spreadsheet software such as Microsoft Excel making it easy to log data. VersaWave’s use of external optical fibre connections allows the use of different holders and measuring devices to increase dynamic range, sensitivity and applications. Versawave accessories include:

Versavette Cuvette Holder: For measurement of traditional glass, plastic or quartz 10mm cuvettes, as well as the full range of micro and reduced pathlength cuvettes with a Z dimension (beam height) of 15mm. This is adjustable with an adapter.

VersaCell: For measurement of high absorbance, low volume samples without dilution. Obtain measurements from as little as 0.6µl of sample with DNA concentrations ranging from 6 ng/µl to 12,500 ng/µl and protein concentrations as low as 0.2 mg/ml. VersaCells are available with pathlengths of 0.125mm, 0.2mm and 0.5mm.

VersaTray: A microvolume cuvette for measurement of minimal volume samples without dilution. Measurements require as little as 0.7µl of sample and can detect as little as 5 ng/µl of DNA up to 7500 ng/µl of DNA. A minimum of 0.1mg/ml of protein can be detected. VersaTrays are available with pathlengths of 0.2mm or 1mm.

VersaFlow: A flowcell attachment which allows on-line monitoring for flow systems. Reactants/products are measured as they move from the reaction vessel along inert PFA tubing and into the flowcell. Up to four wavelengths can be measured simultaneously as a function of time.

VersaProbe Immersion Probe: Allows direct absorption measurements of liquid samples by immersion of the chemically inert probe, and is particularly suited for large containers or constant streams of sample. Optical pathlengths from 2mm to 40mm are available as interchangeable screw-in tips for industrial or scientific applications.

Controlled Atmosphere Work: The flexible optical fibres of the VersaWave allow the bulk of hardware to remain outside atmospherically controlled chambers, such as for work with viruses, infectious, or anaerobic microorganisms while the measuring device remains inside. This protects the VersaWave from contamination, allows easy operation and increases available space inside the chamber.

Custom Applications: Expedeon’s experts have already designed a number of custom attachments for specific applications. Please contact us to discuss any specific needs not already covered by our current range of attachments.

Applications

The VersaWave is a versatile spectrophotometer with a number of applications. These include, but are not limited to:

• •  Protein concentration measurements, either through direct absorption or by indirect techniques such as Bradford, Lowry, and BCA assays.
• •  Nucleic acid concentration measurements, such as ssDNA, dsDNA and RNA. A wide range of concentrations are measurable due to the high dynamic range of the VersaWave which can augmented by using different attachments.
• •  Cell density measurements by determining the optical density at 600nm.
• •  Full spectrum analysis of samples can be completed in a matter of seconds.
• •  Contaminant measurement for a range of different samples

Cost Effectiveness

The VersaWave has a low buying price when compared to other microvolume spectrophotometers and allows a wider range of applications through versatile attachments. The VersaWave is reliable and doesn’t require calibration or a servicing contract due to the lack of moving parts. The unique VersaTip allows speedy sample reading and all sample can be recovered after each measurement. A small footprint saves bench space and allows the VersaWave to easily fit into the most crowded laboratories. The VersaWave comes with a one year warranty as standard and is extendable to two years.
