Alltesta™ Mini-Autosampler
The Alltesta™ Mini-Autosampler, developed by SIELC Technologies, is a cost-effective solution for automated liquid sample handling in various environments, including HPLC. Its compact design and customizable configurations make it ideal for laboratories with limited bench space and mobile instrumentation settings.
The system combines flexible hardware configurations with sample mixing capabilities. Available options include different valve configurations, syringe capacities, needle types, vial trays, and well plates. An open serial command protocol supports integration into existing instruments and custom automation workflows.
Key Features
- Built-In Shaking: Mix samples before injection, perform extraction directly within a vial, or quench samples with reagent delivered by the syringe pump.
- Compact Design: Save valuable bench space and integrate automated sample handling into compact or mobile instruments.
- Direct Serial Control: Control individual modules through a comprehensive serial command protocol for integration with existing systems or custom software.
- Flexible Configuration: Select valve configurations, syringe capacities, needle types, vial trays, and well plates to match your application.
- OEM Customization: Custom shapes, colors, and vial sizes are available for integration into OEM instruments.
Automated Liquid Handling Capabilities
The Alltesta™ Mini-Autosampler supports a range of liquid handling workflows. Depending on the application, software modifications and a suitable hardware configuration may be required.
- Fraction Collection: With a software modification, the autosampler can function as a fraction collector, collecting individual fractions in designated vials.
- Reactor Probe Sampling: The autosampler can be adapted through a software modification for reactor probe sampling.
- Sequential Sample Delivery: Deliver a series of samples to detectors or spectrometers, including NMR and MS systems. The compact design allows placement close to the measuring cell, helping minimize sample spreading and measurement delay.
- Reagent Addition, Sample Dilution, and Mixing: Prepare samples for subsequent analytical steps using integrated liquid handling and mixing capabilities.
- Loading Fluidic Devices: Automate sample storage and delivery to microfluidic devices, with user-adjustable sample volumes delivered to a line connected to the chip.
- Sequential Fluorescence In Situ Hybridization (seqFISH+): Automate RNA fluorescent marker delivery and provide access to multiple buffers for seqFISH+ workflows.
The Alltesta™ Mini-Autosampler can also be used as a component of Alltesta™ Analyzers.
