  • Page 7: Introduction

    INTRODUCTION  The latest line of Wheaton Biostir magnetic stirrers answers the call to many modern laboratory needs. Features include wide speed ranges, increased  torque, easy user interface, and remote control options allow the Biostir to cover a wide range of applications. A new addition of interval and two speed stirring modes adds to the versatility of the unit.

  • Page 8: Major Component Identification

    MAJOR COMPONENT IDENTIFICATION FRONT OF UNIT 1. Display –When the unit is running, the display shows the current operating status of the unit, including operating speeds and cycle times. While the unit is idle, the display shows entered data from the keypad and remote communications status.

  • Page 9: Initial Inspection

    INITIAL INSPECTION  When you receive your new Biostir , inspect it for any obvious damage that may have occurred during shipment. If any damage is found, notify the carrier at once. Warranty information is shown in the front of this manual. Check to confirm that there are no broken switches, displays or missing parts, and that the unit is not dented or scratched.

  • Page 10: Unit Setup And Operation

    UNIT SETUP AND OPERATION  The Biostir slow speed stirrer can be configured in several different modes to allow for simple constant speed stirring, to advanced interval and two speed stirring for the most demanding applications. Keypad and Display  The Biostir keypad and display provide useful information to the setup and performance of the unit.

  • Page 11: Vessel Placement

    Vessel Placement Make sure the vessel is centered on the “target” area on the top of the stirrer. A vessel that is not centered may cause uneven stirring, resulting in less than optimum results.  2004 Wheaton Science Products P/N 50083244 Specifications subject to change without prior notice...

  • Page 12: Basic Constant Speed Stirring

    Basic Constant Speed Stirring  The Biostir is capable of basic stirring as well as advanced stirring modes for demanding applications. To run in basic constant-speed stirring mode, set the unit as follows: IF THE UNIT IS RUNNING, OR AUTOMATICALLY STARTS WHEN POWER IS APPLIED: •...

  • Page 14 • Press RUN / STOP to start the unit running at the set constant speed. The RUN light will blink while the unit is ramping to the set speed. The RUN light will light constant once the set speed is achieved, indicating the unit is working properly.

  • Page 15: Cycle Stirring

    Cycle Stirring ® The Biostir can be set to run in cycle stirring mode, where the unit will run a set number of alternating stirring and idle times. This type of stirring may be especially helpful in cell culture applications during initial seeding where cells need a set idle time during the stirrer / growth cycle.

  • Page 23: Stirrer State In Case Of Power Interruption

    Stirrer State In Case of Power Interruption ® The internal electronics of the Biostir are able to store certain operational settings of the unit in RAM that will not be erased when power is lost to the unit. The RUN RPM value is preserved, while all other set values are lost, such as cycle run time, cycle off time, cycle RPM and cycle count.

  • Page 24: Remote Control Operation

    REMOTE CONTROL OPERATIONS The optional remote control box is plugged into the unit via the rear RS485 port. The remote control can then be placed in a more convenient location away from the main unit. The remote control front panel has the identical appearance and functions as the front panel on the main unit.
