Inline Automation Optimized for Continuous Array Tape®

Array Tape

Global deployments throughout North & South America, Asia, and Europe are proving daily that the Array Tape Platform is transforming lab automation as we know it.

Achieve quality data with repeatable results in a flexible, high throughput system at a lower cost per data point. Douglas Scientific provides inline, modular instrumentation that is fully integrated and optimized for use with our revolutionary consumable, Array Tape. This low cost, flexible microplate replacement enables automation of multiple laboratory processes on a single platform. The highly automated and robust system allows scientists to focus less on the automation and more on the data and other value added tasks.

The unique combination of the Array Tape consumable, Nexar® liquid handling and assay processing system, Soellex® PCR thermal cycler and Araya® inline fluorescent detection enables a continuous reel to reel process flow needed to maximize throughput and reduce costs.

Step 1: Nexar liquid handling and assay processing
Step 2: Soellex PCR Thermal Cycler
Step 3: Araya Detection

Microplate Based Technology Without Manual Handling

The design of Array Tape and the modular inline platform maintains the flexibility of microplate-based technology while virtually eliminating manual handling and complex robotics. Indexing holes along the edge of Array Tape accurately position and continuously feed reaction wells through the Nexar and Araya. Each 96 or 384-well array in Tape is labeled with a unique barcode ensuring accurate identification of individual samples during and after processing.

Automatic Continuous Feed Process

Here is one example of how a process can be streamlined. Consider a SNP Genotyping Application:

Build Assay
Typical Process
Step 1: Dispense 8 microliters a single 384- microplate at a time
Step 2: Seal the microplate
Step 3: Stack the microplates
Douglas Scientific Process
Step 1: The Nexar dispenses 800 µL sample and 800 uL reagent in the equivalent of 200 plates in a continuous strip of Array Tape, seals it, and winds the samples on a dunker reel
Typical Process
Run microplates through PCR 16 or 32 at a time
Douglas Scientific Process
Entire reel of Array Tape is loaded into the Soellex water bath for approximately 90-120 minutes
Typical Process
Dry Microplate
Douglas Scientific Process
Dry reel of Array Tape (optional on a custom centrifuge)
Typical Process
Scan Microplate (~ 1.5 – 2.5 minutes)
Douglas Scientific Process
The Araya scans the entire reel at a rate of 28 seconds per 384-well array
Plates per day:
Typical Process
150 microplates (384 wells)
Douglas Scientific Process
400 arrays (384 wells)
Data points per day:
Typical Process
Douglas Scientific Process
Lab processing time
Typical Process
10 hours
Douglas Scientific Process
8 hours
