Scientific Industries Genie SI-5256 Digital Quadmag Multiposition Stirrer 230V User Manual

1. Introduction

The Scientific Industries Genie SI-5256 Digital Quadmag Multiposition Stirrer is a robust laboratory instrument designed for efficient and reliable mixing of liquids. This four-position stirrer utilizes powerful magnets to ensure stir bars remain coupled even under demanding conditions. Its durable, spill-resistant ABS/polycarbonate housing protects internal components from spills. The unit features an internal ramping function for gradual speed increase, minimizing splashing and enhancing control. It is capable of stirring up to 2 liters per position and is suitable for use in various environments, including cold rooms and incubators.

2. Safety Information

• Read and understand all instructions before operating the stirrer.
• Ensure the power supply matches the unit's requirements (230V, 50Hz).
• Always use appropriate personal protective equipment (PPE) when handling chemicals or operating laboratory equipment.
• Do not operate the stirrer with a damaged power cord or plug.
• Avoid placing the stirrer in areas where it may be exposed to excessive moisture or extreme temperatures beyond its operating range.
• Do not immerse the unit in water or other liquids.
• Ensure vessels are securely placed on the stirring platform to prevent spills or accidents during operation.
• Disconnect the power before cleaning or performing any maintenance.

3. Package Contents

Verify that all items are present and undamaged upon unpacking:

• Genie SI-5256 Digital Quadmag Multiposition Stirrer (1 unit)
• Power Cord (European Plug, 230V compatible) (1 unit)
• User Manual (this document) (1 unit)
• Note: Stir bars and beakers are typically sold separately.

4. Setup

1. Unpacking: Carefully remove the stirrer from its packaging. Retain packaging for future transport or storage.
2. Placement: Place the stirrer on a stable, level, and clean surface in a well-ventilated area. Ensure adequate clearance around the unit for proper air circulation. The unit is suitable for use in cold rooms and incubators.
3. Power Connection: Connect the provided power cord to the stirrer's power inlet and then plug it into a grounded 230V, 50Hz electrical outlet. The unit is equipped with a European plug type.
4. Initial Inspection: Before first use, inspect the unit for any visible damage. If damage is observed, do not operate the unit and contact customer support.

5. Operating Instructions

1. Prepare Vessels: Fill your beakers or other appropriate vessels with the liquid to be stirred. Place a suitable stir bar into each vessel.
2. Position Vessels: Carefully place up to four vessels on the stirring platform, aligning them over the designated stirring positions. Ensure the vessels are stable. The maximum stirring volume per position is 2 liters.
3. Power On: Turn on the stirrer using the main power switch (if present) or by ensuring it is plugged in. The digital display should illuminate.
4. Set Stirring Speed: Use the graduated analog dial to set the desired stirring speed. The internal ramping feature will gradually increase the speed to the set point, minimizing splashing and improving control of the stir bar. The speed range is from 250 rpm (low) to 1300 rpm (high).
5. Monitor Operation: Observe the stirring process. The powerful magnets will pull the stir bars into position and maintain coupling throughout the operation.
6. Power Off: Once stirring is complete, turn the speed dial to its minimum setting or turn off the power switch. Allow the stir bars to stop completely before removing vessels.

6. Maintenance

• Cleaning: Disconnect the unit from the power supply before cleaning. The durable, spill-resistant ABS/polycarbonate housing is designed to direct spills away from internal components. Wipe the exterior surfaces with a damp cloth and a mild detergent. Do not use abrasive cleaners or solvents. Ensure the unit is completely dry before reconnecting to power.
• Inspection: Regularly inspect the power cord for any signs of damage. Check the stirring platform for any residue or wear.
• Storage: When not in use for extended periods, store the stirrer in a clean, dry environment, preferably in its original packaging.
