The Wincom Digital Tube Automatic Part Collector (Fraction Collector) is an intelligent, high-precision laboratory instrument designed to automatically collect liquid samples or fractions from chromatography columns, purification systems, and chemical reactors. Featuring a programmable digital control unit, a multi-tube carousel rack, and automated tube-switching mechanisms, it eliminates the need for manual monitoring. It is a vital tool for high-efficiency separation and purification workflows in biochemistry, molecular biology, pharmaceuticals, and natural product extraction.

Key Features

• Multi-Mode Automated Collection: Offers maximum versatility by allowing operators to switch seamlessly between time-delay, volume-metering, or exact drop-count tracking modes.

• Intelligent Digital Interface: The clear digital console displays real-time parameters, including current tube number, elapsed collection time, drop count, and operational steps.

• Precise Alignment and Stepping Motor: Driven by a high-accuracy digital stepping motor that ensures the delivery nozzle centers perfectly over each tube, eliminating accidental spillage.

• Automatic Waste Diversion Valve: Equipped with an electronic solenoid valve that automatically redirects the liquid flow to a waste container during tube switching, preventing cross-contamination between fractions.

• Chemical-Resistant Construction: Built with a rugged, corrosion-resistant body and stable tube racks that easily withstand accidental exposure to organic solvents, acids, and buffer solutions.

Primary Applications

• Liquid Chromatography and Purification: Automating the collection of separated chemical bands or target proteins coming out of analytical and semi-preparative HPLC/column setups.

• Natural Product Extraction: Systematically harvesting isolated fractions of plant extracts, essential oils, and herbal compounds for subsequent bioassays.

• Biopharmaceutical and DNA Research: Collecting purified amino acids, nucleic acids, enzymes, and specialized peptide sequences from synthesis columns.

• Laboratory Process Automation: Continuous sampling and time-course monitoring of chemical reaction solutions in research and development plants.
