Description

Pro Multifunctional Orbital Decolorizing Shaker

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Syphilis Serology Testing (RPR/TRUST)

Primary Use: Provides consistent large-platform orbital shaking for rapid plasma reagin (RPR) and toluidine red unheated serum test (TRUST) syphilis screening, with a working tray that can be equipped with an optional transparent top cover and built-in thermal insulation device for placing sponges specifically for these tests .
How it helps: For the medical technologist and clinical laboratory scientist, the SK-O330-Pro ensures standardized agitation for RPR card tests with a larger work area, allowing batch processing of multiple patient samples simultaneously, reducing inter-run variability, and improving reproducibility of qualitative and semi-quantitative syphilis results. For the patient, standardized serological testing contributes to accurate diagnosis of syphilis infection, enabling appropriate antibiotic treatment and preventing disease progression.

2. Gel Staining and Destaining for Protein Analysis

Primary Use: Accommodates large staining trays and containers for Coomassie Blue and silver staining of protein gels following electrophoresis, providing smooth orbital motion (10mm amplitude) for uniform reagent coverage and efficient destaining .
How it helps: For the clinical biochemist and laboratory scientist, the SK-O330-Pro’s 10mm orbital amplitude and 100-500 rpm speed range enable even staining and rapid destaining of multiple polyacrylamide gels simultaneously—improving band visualization and reducing background interference. The larger 320×320mm work plate accommodates gels of various sizes for high-throughput protein analysis. For the patient, reliable protein analysis supports diagnosis of hemoglobinopathies, multiple myeloma, and other protein disorders where accurate gel interpretation guides clinical management.

3. DNA Hybridization and Molecular Assays

Primary Use: Used for Southern blot, Northern blot, and Western blot hybridization steps, ensuring uniform probe distribution and consistent washing conditions for membrane-based assays .
How it helps: For the molecular biologist and clinical laboratory scientist, the SK-O330-Pro’s digital speed control, timer function (1 min-99 hr 59 min), and larger capacity enable reproducible hybridization and stringent wash steps for multiple blots simultaneously—improving signal-to-noise ratios and reducing non-specific binding . For the patient undergoing molecular genetic testing, reliable hybridization results contribute to accurate detection of genetic mutations, infectious agents, or cancer biomarkers.

4. General Large-Volume Sample Mixing and Reagent Preparation

Primary Use: Facilitates mixing of multiple blood collection tubes, large-volume reagent preparations, buffer solutions, and liquid cultures prior to analysis or further processing, with a maximum load capacity of 7.5 kg .
How it helps: For the clinical laboratory scientist, the shaker’s continuous or timed operation modes and larger work surface (320×320mm) ensure consistent mixing of anticoagulated blood samples for hematology testing and homogeneous reagent suspensions for automated analyzers—improving pre-analytical quality while processing more samples per run. For the patient, proper sample mixing before analysis reduces result variability and the likelihood of repeat specimen collection.
