INTRODUCTION Intended Use The BioReactor Sciences (BRS) GM100 Glucose Monitoring System is designed to quantitatively measure the glucose concentration in microbial and cell cultures for bioprocessing applications. The GM100 System uses the latest glucose monitoring technology to provide you a simple, rapid, relatively accurate, and inexpensive way to measure glucose concentration in culture medium. The system requires only a 2.5µL of medium sample to complete the testing in only 10 seconds. The System Includes: One (1) GM100 Glucose Meter Fifty (50) GMTS100 Glucose Test Strips (includes Code Key) GM100 Check Key Carrying Case Quick Reference Guide and User s Operational Manual available on website: http://www.bioreactorsciences.com/gm-100- portable-glucose-meter.html 3
UNDERSTANDING THE GM100 GLUCOSE MONITORING SYSTEM Top Bottom Explanation of the Full Display Screen NOTE: Meters are programmed to show results in either mg/dl or mmol/l. See Meter Set-up to select the units of measurement. GMTS50 Test Strips These test strips need only 2.5 µl (microliter) of medium. Apply medium to the sample application tip. The strip draws in the medium by capillary action. The medium glucose reacts with the enzyme on the test strip. This produces a current proportional to the medium glucose level. The meter detects the current and converts it into a glucose measurement. GMTS50 Test Strips are intended for use only with the GM100. Each batch of test strips is assigned a specific 3 digit code that must be loaded into the meter. 4
Test Strip Sample is drawn up on this tip end with arrow This electrode end to be inserted into the meter Changing the Battery The GM100 Glucose Monitoring System comes with 2 AAA batteries (not pre-installed or not included for security regulation). NOTE: Replacing the battery will not delete meter settings or test results stored in the meter. To save battery power, the meter turns itself off after a period 3-5 minutes of inactivity. Replace batteries when the low battery symbol appears. Otherwise inaccurate results may be obtained. Discard used batteries per local guidelines. To replace batteries: 1. Turn meter off. 2. Remove the battery cover on the back of the meter, by sliding it downward. 3. Load new batteries into the battery carriage, aligning the "+" and "-" ends. 4. Reattach the battery cover. 5
METER SET-UP Basic Rules Meter set-up allows you to set the year, date, time, and units of measurement. Before using the GM100 Glucose Monitoring System for the first time, set the time and date. Do not perform a medium glucose test until you have set-up the meter. Setting the Clock (Year, Date, Time) 1. Install batteries (if not already installed). 2. In the battery panel, press the left button to turn the meter on. 3. The first blinking number designates the year (13=2013, 14=2014, etc.). Press the front button to change/advance the year number. After the target year appears, press the back left button to change the selection to month. 4. The month number designation should start blinking. Once blinking you can now change the month. Press the front button until your desired month number is displayed. After the proper month appears, press the back left button to change the selection to day. 5. The day-number designation (top right hand corner) should now be blinking. Once blinking you can now adjust the day. Press the front button until your desired day number is displayed. After the proper day appears, press the back left button to change the selection to time-hour. 6. The hour-number designation in military time (middle) should now be blinking. Once blinking you can now adjust the hour. Press the front button until your desired hour is displayed. After the proper hour appears, press the back left button to change the selection to time-minutes. 7. The minutes-number designation (middle-right) should now be blinking. Once blinking you can now adjust the minutes. Press the front button until your desired minutes is displayed. Hold the button down to advance. After the proper minutes appear, press the back left button to power the meter off. 8. "OFF" should appear on the meter display. The clock has now been set. Selecting the Units of Measurement (mg/dl or mmol/l) 1. In the battery panel, the switch in the lower right hand corner designates the units of measurement. 2. To use the meter with the units of measurement as mg/dl, switch the lower right hand switch
to the RIGHT. When a test strip is inserted and the meter powered on, the units "mg/dl" will appear in the lower right hand corner. 3. To use the meter with the units of measurement as mmol/l, switch the lower right hand switch to the LEFT. When a test strip is inserted and the meter powered on, the units "mmol/l" will appear in the lower right hand corner. Verifying Meter is Properly Functioning Verify the meter is properly functioning with the included check key. 1. Insert the check key into the meter. 2. If "ABC" appears on the meter display, the meter is functioning properly. Remove the check "key" to power the meter off. If "E01" or anything other than "ABC" appears on the meter display after inserting the check key, the meter is not functioning properly. Reset meter by removing and reinserting batteries. If resetting meter does not correct error please contact your BRS sales representative. Loading Meter Test Strip Code With every batch of test strips, the meter must be loaded with a specific 3 digit code associated with that batch of test strips, via a Code Key that has the 3 digit code written on it. 1. To load the strip's specific 3 digit code, insert the Code Key that is included with each batch of strips. 2. After inserting the Code Key into the meter, the same 3 digit code should be displayed on the meter. The meter is now ready to be used with that batch of test strips. 3. If the 3 digit code does not match, please make sure that the 3 digit code on the key coincides with the 3 digit code on the strip's bottle. 4. If the 3 digit code on the key matches the 3 digit code on the bottle, and if the proper 3 digit code is not displayed, please contact your BRS sales representative or distributor.
PERFORMING A CONTROL STANDARD SOLUTION TEST The control standard solution test is used to verify that the GM100 Glucose Monitoring System and Test Strips are working together as a system. This test is performed at BioReactor Sciences before shipping and is normally not required by the user. It is however and optional test that can be conducted as frequently as you wish using a standard solution prepared by yourself under the below situations. 1. When you suspect the meter or strips are not properly performing. 2. When the glucose measurement seems inaccurate. 3. If the meter is dropped. Prepare the control standard solution as follows: Standard A: use the fresh medium of your process/of your preference with known glucose concentration Standard B ([¾] of Std A): 3 parts of Std A + 1 part of Z (glucose-free medium if available or PBS buffer solution) Standard C: ([½] of Std A): 1 part of Std A + 1 part of Z Standard D: ([¼] of Std A): 1 part of Std A + 3 parts of Z IMPORTANT: 1. Store aseptically the control standard solution in a refrigerator 2. The enzymatic reaction rate may be affected by physical conditions such as ph and temperature, and by the contents in the media other than glucose. To Conduct a Test Using the Control Standard Solution: 1. Open the bottle of test strips. 2. Remove a new strip from the bottle. Close the bottle's lid to preserve the strip's shelf life. 3. Insert a new strip into the meter with the electrode side first. The strip should seat FIRMLY into the meter. The meter will turn on automatically. A 3 digit code will appear on the meter's front display. Confirm that the 3 digit code is displayed, and that it coincides with the strip's 3 digit code on the bottle. 4. The droplet symbol will start flashing on the meter. You may now place the tip of the strip into the droplet of standard solution in an angle of >45 degree. The sample will be drawn in and the meter will emit a beep when a sufficient sample size has been submitted. 5. The meter will begin counting down from 10. Your glucose measurement will then be displayed
Troubleshooting Control Standard Solution Test Measure the glucose of all four standard solutions twice for each solution using the key provided. If the measurements do not match the glucose concentration of the control solution and is not within the accepted accuracy range (+/- 10% of the standard concentration) please contact your BRS representative or distributor. GLUCOSE MEASUREMENT Performing a Glucose Test NOTE: Three (3) minutes after test strip insertion, the meter turns off. To turn the meter back on either press the front button or remove the unused test strip and insert it again. 1. If present, remove any strip, check or code key from the meter. 2. Open the bottle of test strips. 3. Remove a new strip from the bottle. Close the bottle's lid to best preserve the strips shelf life. 4. Insert a new strip into the meter with the electrode side first. The strip should seat FIRMLY into the meter. The meter will turn on automatically. A 3 digit code will appear on the meter's front display. Confirm that the 3 digit code is displayed, and that it coincides with the strip's 3 digit code on the bottle. 5. The droplet symbol will start flashing on the meter. You may now place the tip of the strip into your sample in an angle of >45 degree. The sample will be drawn in and the meter will emit a beep when a sufficient sample size has been submitted. 6. Remove or move the strip away from the sample. The meter will begin counting down from 10. Your glucose measurement will then be displayed
