Setup Instructions

1. Kuburitsa: Carefully remove the dispenser and all components from the packaging. Inspect for any visible damage.
2. Syringe Installation: Insert six 1700RN series Gastight syringes into the designated slots on the dispenser. Ensure they are securely seated. The plungers should align with the dispensing mechanism.
3. Needle Attachment: Attach appropriate dispensing needles to the luer lock or threaded syringe tips. Ensure a tight, leak-free connection.
4. Priming: Before first use, prime each syringe by drawing and expelling the intended liquid several times to remove any air bubbles and ensure consistent flow.
5. Calibration (if necessary): For critical applications, verify the dispensed volume using a calibrated balance or other suitable method. Adjust as needed according to laboratory protocols.

Operating Instruction

The Hamilton 201930 dispenser is designed for simultaneous, precise dispensing of 5 microliter volumes from each of its six syringes.

1. Load Syringes: Ensure each of the six 1700RN series Gastight syringes is filled with the desired liquid, up to its 250 microliter capacity. Avoid overfilling.
2. Positioning: Position the dispenser over the target wells, such as a Terasaki plate. Ensure the dispensing needles are correctly aligned with the wells to prevent spillage.
3. Dispense: Actuate the dispensing mechanism. This will simultaneously depress the plungers of all six syringes, delivering 5 microliters from each. The mechanism is designed for consistent, equal volume dispensing across all channels.
4. Dzokorora: If multiple dispenses are required into the same wells or new wells, reposition the dispenser and repeat the dispense action.
5. Kuzadza patsva: When syringes are depleted, refill them as needed, ensuring proper priming before resuming dispensing.
