Array Tape Advanced Consumable Continuous Polymer Array TapeArray Tape is a continuous polymer strip, serially embossed with reaction wells in customized volumes and formats including 96-, 384- and 768-well arrays. Array Tape is thin (0.3 mm) and flexible, which allows up to 800 microplate equivalents to be spooled onto a single reel. It is a flexible microplate replacement for applications that enables a streamlined lab process. Reduced Cost Sub-Microliter ReactionsCurrent applications support sub-microliter reactions ( 800 nL). These fluid volumes are significantly less than microtiter plates where the minimum practical reagent volume is approximately 5L in a 384-well plate. The smaller reaction volumes in Array Tape reduce reagent costs by 80-90% compared to microplate-based systems. Array Tape not only enables significant increases in throughput due to inline processing, but also dramatically reduces cost per data point. Douglas Scientific provides clean consumable Array Tape - certified by an outside lab to be RNAse, DNAse, and pyrogen free.

Soellex High Throughput PCR Thermal Cycler Thermal Cycle 230, 400 Data Points in a Single Process RunThe Soellex is an ultra high throughput end-point polymerase chain reaction (PCR) thermal cycler leveraging a 3-chamber water bath. The heating system in the Soellex tightly controls the temperature throughout the water bath delivering efficient and rapid energy transfer from the water, through the Array Tape and to your samples. Thermal Cycle 230, 400 Data Points SimultaneouslyThe Soellex is capable of simultaneously processing up to three spools of Array Tape, each with two hundred 384-well arrays per spool. Therefore, the Soellex has the potential to thermal cycle between 76, 800 and 230, 400 reaction wells in a single process run. Intuitive Thermal Cycler User InterfaceThe touch screen user interface is simple, yet feature rich, providing the control necessary to process requirements. It includes: Intuitive run progress and monitoring feedback screenThermal cycling protocol programming wizardCustomizable alarms and warningsRemote computer monitoringnotificationReports generation and log file reviewerAnd more!High Throughput Energy SavingsHigh throughput processing of up to 230, 400 samples in Array Tape requires one Soellex water bath - replacing the 18 water baths (32 plate capacity) or 150 block heaters required for microplates. These energy and space saving benefits put high throughput laboratories well on their way to achieving significantly greener, more environmentally sound operations. Common End Point PCR ChemistriesThe Soellex supports all common end-point PCR chemistries including but not limited to TaqMan and InvaderPLUS. Versatile Microplate System DesignThe Soellex system design is versatile and supports PCR processing in traditional microtiter plates as well as in Array Tape. The Soellex can process up to 152 microplates (384-well, 11 mm tall) in a single run. Decrease Thermal Cycling TimesArray Tape allows miniaturization of the reaction, has thin walls and low thermal mass (7 times less than a microplate) enabling rapid temperature changes contributing to shorter cycle times and improved results. Laboratory scientists who have experienced nonspecific binding issues recognize sharp temperature changes in Array Tape as a key advantage.

CyBio Dispense Pipette and Wash Station Customizable Rapid Dispense PipetteThe Dispense Pipette contains an integrated CyBio Light Pipetting Head. It can be customized with a 96 or 384 tip tray. Aspirate and dispense volumes, along with CVs, are determined by the type and style of pipettor and tip tray used. Typically, a large volume of sample is aspirated and a smaller volume is dispensed simultaneously into each well in the array. The Dispense Pipette Attachment also contains a 1D2D barcode reader that can read the 2D code on the Array Tape and the 1D (linear) code on the end of the source plate. Parallel channel pipetting from plates using the CyBio LDH head provides rapid sample and reagent dispense into Array Tape using 96- or 384-tips in either full or quadrant stamping in a range of 600 nL to 800 nL. Pipetting Head SpecificationsCYBIO 384 HEAD (CYBIO)Mechanism: Simultaneous air displacementManufacturer Suggested Volume Range: 0.2 - 10 L 25.0 L (dependent on tip vol.)Manufacturer Precision: CV < 2%, at 1.0 LCyBio Dispense Pipette Wash StationsDouglas Scientific offers a pair of dispense pipette washing options to meet sample cleansing needs. Pipette Wash The Pipette Wash provides your first defense against cross-contamination while minimizing contaminant carryover between plates. When the wash procedure is used at the start and end of your daily analytical runs, the Pipette Wash provides a high degree of certainty that other air-borne contaminants are eliminated. During normal analytical runs, the wash procedure is automatically controlled by the Nexars built-in software andor protocols. The Sonic Wash provides ultrasonic washing of pipette tips to clean residual samples from nozzles and pipette tips. Water is plumbed into the tub and overflows the edges into a collection trough to be pumped out of the instrument. Ultrasonic cleaning is provided by a transducer mounted under the tub while water in the tub is aspirated and flushed out multiple times to remove residual sample.

Expansion Block Module DehydratorThe Dehydrator, mounted in the Expansion Block Module, is used to dry down sample as Array Tape is passed and paused underneath. This attachment takes incoming dry air and heats it to a preset temperature. Dry down times vary based on the volume of sample present.

Nexar Plate StackerNexar Plate StackerThe Plate Stacker, mounted in the Expansion Block Module, is used to store source or reagent plates up to 335mm high in each of the two removable extruded aluminum chutes. Each chute can be designed as an incoming or outgoing rack. Plates are automatically moved to and from the chutes without manual intervention through use of solenoids, a motorized lift arm, and conveyor system.

The user interface (UI) provides flexibility in each key area: Nexar User InterfaceSystem Configuration The UI displays only the necessary options based on the system configuration.Auto or Manual - Systems can be operated in automatic mode with little to no user interaction or manually with full user control.For information on protocol generation, data management and scoring, view the Intellics Software overview.

Multi-Channel Dispense Jet Four Tip Dispense JetNexar FlexJet Dispense JetThe Dispense Jet is an independent, multi-channel attachment containing four or eight nozzles to aspirate and dispense reagent from a plate to Array Tape. The Dispense Jet moves horizontally (x and y-axis) and vertically (z-axis) on the Positioning Rail, allowing the nozzle(s) to reach any well in the Array Tape. Typically, a large volume of reagent is aspirated into each nozzle and smaller volumes are dispensed into the Array Tape. The Dispense Jet Attachment also contains a 1D2D barcode reader that can read the 2D code on the Array Tape and the 1D code on the end of the plate.
