Statement of Work (SOW) Project: Liquid Handling Station with Autosampler

GENERAL INFORMATION

1.0 Scope of Work: Purpose is to procure one benchtop, liquid handling station to serve a dual function as an autodiluter for liquid samples and as an autosampler for an inductively coupled plasma-optical emission spectroscopy (ICP-OES) instrument that analyzes liquid samples for elemental analysis.

2.0 Background: The ATRU worksite in Toledo, OH, conducts research to improve crop production in controlled environment agriculture (CEA) facilities, including crop production and crop nutrition. As part of this research, quantifying the elemental concentration of plants, water, and soilless substrate components is essential. As part of the sample preparation, samples must be diluted and transferred to new sample vials multiple times prior to analysis. A liquid handling station with autosampler is critical for efficient, accurate, high throughput of these samples.

CONTRACTOR REQUIREMENTS

3.0 Technical Requirements/Tasks: Provide and deliver one SimPrep with 560 Autosampler, or equivalent, with the following characteristics/capabilities:

· Overall dimensions no greater than 23” width x 23.5” depth x 24” height for autosampler

· Overall dimensions of 5.5” width x 7” depth x 10.5” height for the dilution module

· Tray for autosampler holds four racks, such as those that contain 60 x 14 mL or 24 x 30 mL or 21 x 50 mL
