3. m replaces common drilled out aluminum block dry baths in the lab and eliminates the need for using different size blocks to fit different sample vessels Bead Block can be lifted out of the DryTemp unit for portable use anywhere in the lab Each DryTemp has a bright LED display easy to set temperature and time controls Intended Use For research use only CAUTION Hot surfaces especially on the block can cause serious injury or burns Do not put water or liquids into the well as shock serious injury and death may occur Do not heat flammable or explosive substances as serious injury and death may occur WARNING Features v Compatible with a broad temperature range from Ambient 5 to 150 C v Transfers dry heat with high efficiency to warm thaw and incubate samples at constant temperatures v Accepts and supports any shape vessel including tubes plates dishes and other non water tight vessels v Stays clean and disinfects easily Tips and Hints Keep bath dry of liquids during use to avoid damaging bead performance v Wash clean of any spills with soap and water completely dry beads before returning to the bath v If necessary disinfect beads periodically with 70 ethanol solution spray lightly then stir into bath v Avoid using strong acids bases including bleach solutions and detergents which can tarnish the Beads v Always use gloves when handling beads to avoid contaminating the bath v Bead
4. order to determine if bath optimization or protocol adjustments are necessary for a given application first compare performance in both a solid dry bath aluminum heat block and in Bead Block Once a protocol is validated in order to ensure reproducibility always keep the established conditions constant between experiments for a given application Bury Vessels in Beads to Avoid Condensation When using a solid dry bath aluminum heat block vessels have an internal temperature gradient since only a portion of the vessel is recessed into the block and the remaining is exposed to room temperature This often produces condensation under the lid of a vessel which can alter the concentration of the sample In a Bead Block the following can be performed to eliminate condensation under the lid Incubate vessels at an angle and bury or completely submerged the vessel into Lab Armor Bead Technical Support For additional product and technical information such as product manuals or technical articles on the use of DryTemp and Lab Armor Beads for common laboratory applications please visit our website at www labarmor com For further assistance please email our Technical Support team at www info labarmor com
5. r if the power is lost Using and Setting the Timer DryTemp has a built in digital timer function that sounds a beeping alarm when the set time has been reached The timer does NOT turn off the heater when the set time is reached The Timer feature alerts the user that the time setting has been reached but does not disturb samples being heated Press the Mode button to illuminate the Timer lamp and place DryTemp into the timer set mode Use the Up and Down arrow buttons to set the desired time in one minute increments on the display Once time has been set and after about three seconds DryTemp will make a beep sound illuminate the green Temp Run lamp and automatically begin the timer The display will revert to showing the well temperature and the red Timer lamp will be extinguished When the display shows the well temperature pressing the Mode button will cause the display to show how much time remains on the timer in minutes When time has expired the DryTemp will briefly sound the beeping alarm and flash the red Heating lamp The display will show a set of characters that represent the word OVER with only a partial R shown Sample heating will be unaffected At this point the user can press the Mode button to start the timed cycle over again or press the Down arrow button and the display will show the current well temperature without re starting the timer The green Temp Run lamp will remain illuminated unti
6. s have been shown to perform for a minimum of 2 years from date of manufacture when using good laboratory practices If beads become dull with misuse or do not perform as intended it is recommended to replace the beads Specifications Timer 1t0999 minutes _ _ Timer 1 to 999 minutes Set up and Operation Use the following procedures to set up your DryTemp system Preparation Place DryTemp on a stable flat surface away from air vents and any equipment exhaust vents Plug DryTemp into a properly grounded outlet of the correct voltage Insert block s filled with Lab Armor Beads into the heating well Caution blocks may be hot Using the switch on the back of the unit turn the power on The DryTemp will make a beep sound illuminate each digit on the display left to right and briefly illuminate the red and green lamps while it performs a unit test After the unit test the display will begin showing the well temperature and the unit will begin heating the block to the previously set temperature and flashing the Heating lamp Setting the Temperature Use the Up and Down arrow buttons to increase or decrease the temperature setting The temperature can be set in tenths of a degree C Once the temperature is set the display will then revert to showing the well temperature and the Heating lamp with flash until the set temperature has been reached The temperature setting is automatically remembered if power is turned off o
7. t the set calibration temperature The right hand digit will begin flashing again when the dry bath has equilibrated at the calibration temperature 6 After the display begins flashing use a certified reference thermometer or temperature sensor to check the Bead Block or sample temperature Insert the thermometer into the Beads at about 3 to 5 cm If the reference thermometer shows a difference from the display you can adjust the display to match the thermometer by using the Up and Down buttons 7 After using the reference thermometer and adjusting the display if necessary press the Mode button to exit the calibration mode DryTemp will then be calibrated to the reference thermometer at the selected temperature point and ready for operation EER Code on the display If the DryTemp temperature sensor is shorted or senses an ambient temperature below 0 C the display will show the error code EER DryTemp Use Use the following procedures to optimize the use of your DryTemp system Optimization and Validation for Specific Applications Although the DryTemp Bead Block system is a suitable alternative to solid dry bath aluminum heat blocks in general it is best practice to always verify and validate new laboratory equipment for compatibility with current protocols The goal is to reproduce the conditions of the original experiment performed in a standard dry bath For most applications optimization is not required But in
