Step-by-Step Operating Instructions
1. Load Reagents and Samples
- Open the lid and insert the 96-well deep plate.
- Add magnetic beads, lysis buffer, wash buffer, and elution buffer to the appropriate wells.
- Place the biological sample (blood, saliva, swab, etc.) into the designated wells.
2. Attach the Tip Comb
- Secure the tip comb onto the magnetic rods.
- Ensure it is properly aligned to avoid disruption during mixing.
3. Select Protocol
- Turn on the touch screen.
- From the home screen, choose a pre-saved protocol or load a new one via USB.
- Review the protocol parameters such as mixing time, temperature, and volume
4. Start the Process
Tap Run
The machine will begin the automated cycle:
- Lysis: Breaks down cells and releases nucleic acids
- Binding: Magnetic beads bind with nucleic acids
- Washing: Removes impurities
- Elution: Releases purified DNA/RNA into fresh buffer
5. Monitor Progress
- The screen will show the cycle progress in real time.
- In case of any error, the system will pause and notify you.
6. End of Extraction
- Once completed, the machine will alert you.
- Carefully remove the plate and collect the eluted nucleic acids.
Preparations Before Starting the Machine
Before you begin the extraction process, follow these setup steps:
- Power Connection: Plug the BK-HS32 into a stable AC 100–240V power source.
- Clean the Workspace: Disinfect your lab bench and wear gloves.
- Check Consumables: Have all necessary magnetic beads, reagents, tip combs, and 96-well plates ready.
- Inspect the Machine: Make sure the UV lamp is working and the HEPA filter is clean.
- Software Setup: Load the appropriate protocol or create a new one using the system touch screen.
