Virus Collection Efficiency for the ACD-200 Bobcat Air Sampler
Comparison collection efficiency of the ACD-200 Bobcat Air Sampler vs wet collection reference samplers. Work was performed by Peter Raynor, PhD Professor, Division of Environmental Health Sciences at the School of Public Health, University of Minnesota.
SenseNet Bioaerosol Collector Development
A poster presentation by Dave Alburty, InnovaPrep CEO. The poster was presented at the 2018 American Aerosol Research Conference in St. Louis, MO. The poster described the ongoing SenseNet project funded by The Department of Homeland Security. InnovaPrep is a subcontractor to ENSCO on the SenseNet Project.
The Sensenet project was extended to a Phase IIB in the fall of 2018.
A Rapid and Efficient Sample Preparation Method for Spoilage Organisms Detection in American Lager Beer
A poster presentation by Mike Hornback PhD, InnovaPrep Senior Scientist. The poster was presented at the Association of Brewing Chemists Master Brewer's Conference in San Diego 2018. Upwards of 80%of spoilage organisms in a 355 mL American lager beer sample can be concentrated into under 250 µL quickly using the Be Flat degassing jar and the CP Select in tandem. The beer concentrate can be used for detection using molecular methods, such as qPCR. The CP Select efficiently concentrates L. brevisand B. bruxellensis, resulting in concentration factors of 1000-2000X.
Concentration of Lactobacillus brevis from Experimentally Infected American Lager Beer and Wine by Innovaprep’s Concentrating Pipette and Be Flat Degassing Jar
A poster presentation by Mike Hornback PhD, Senior Scientist, InnovaPrep. The poster was presented at the 2018 International Association for Food Protection. An entire 750 mL bottle of wine was concentrated to under 250 microliters in 7 minutes with a concentration factor of 2024X.

Rapid Concentration of Opportunistic and Pathogenic Fungi from Source Water Samples
A poster presentation by Ariel Lewis, Assistant BioChemical Engineer, InnovaPrep Presented at the 2018 Association of Public Health Labs Meeting. "The CP Select and high flow CPTs were able to effectively concentrate relatively low concentrations of
from surface water very rapidly with a
concentration factor over 2000X for the 1 L sample and over 200X for
the 100 mL samples. When paired with
rapid molecular analysis methods, sample-to-answer can be achieved in a matter of hours with greater sensitivity than
other methods allow.
Sample Concentration Method Analysis
that compared the speed, ease, and efficiency
between the Concentrating Pipette, Glass
Filtration, Centrifugation, and the PALL Sentino on 1 liter samples of cooling
tower and other industrial waters. The method using the Concentrating Pipette was the easiest, fastest,
and gave the best efficiencies as a front end to their CytoFlex flow cytometer. The poster was presented at the CYTO 2017 conference.
Quantitative CrAssphage PCR Assays for Human Fecal Pollution Measurement

Environmental Protection Agency. Findings confirm that viral crAssphage qPCR
assays perform at a similar level to well-established bacterial
human-associated fecal-source-identification approaches. These new viral-based
assays could become important water quality management and research tools. a
200 mL samples were concentrated to a final volume of approximately 150 μL
using an automated Concentrating Pipette with a single-use ultrafiltration
hollow fiber poly(ether sulfone) tip (InnovaPREP, Drexel, MO).
Comparison of methods to determine the microbial quality of alternative irrigation waters
The InnovaPrep Concentrating Pipette
(CP-150) was compared to standard membrane filtration in a recent study by Hsin-Bai
Yina of the University of Maryland, Department of Nutrition and Food Science and
Jitendra Patel of USDA, ARS, Environmental Microbial and Food Safety Laboratory and published in the Journal of Agriculture Water Management.
"The concentrator method was found to
be “superior in detecting virulence genes associated with E. coli O157:H7 in
creek water. The concentrator method is simple, highly effective, and rapid in
detecting bacterial populations in irrigation water and can be used as an
alternative to traditional tedious membrane filtration method.”
"TECHNICAL EVALUATION OF SAMPLE-PROCESSING, COLLECTION, AND PRESERVATION METHODS" by The US Army Research, Development, and Engineering Command
The US Army Research, Development, and Engineering Command report entitled " TECHNICAL EVALUATION OF SAMPLE-PROCESSING, COLLECTION, AND PRESERVATION METHODS" reported on a comparison study of various surface sampling technologies including the InnovaPrep Backpack Surface Sampler, The M-Vac, the BisKit, Copan SRK, and Quicksilver's QS S2P kit and QS S3 swabs. "Overall, the IP Backpack performed the best for sample collection—it was the only device that collected measurable amounts of DNA from each surface tested." The report was published in 2014.
