This can happen when the liquid running through the chamber is not flowing properly.

• Pause your experiment
• Turn off the Okolab environment controller 3A and 3B
• Disconnect the blue end of the connection pipe (at the junction with the spring shape objective warmer)
• Place the open end into a dish to collect liquid
• Turn the Lauda water bath back ON (3B)
• The liquid should flow quite rapidly, if not proceed as follow
  • Turn OFF the Lauda water bath (3B)
  • Take the 20 mL syringe located inside the drawer labelled Tubing
  • Connect it to the open end of the blue pipe
  • Use the syringe to blow pressurized air into the pipes to clear it out
  • Remove the syringe (and store it back into the Tubing drawer)
  • Test if the liquid is now flowing properly by turning the Lauda water bath back ON (3B)
    • If not repeat the procedure
    • If so, turn OFF the Lauda water-bath (3B)
    • Reconnect the blue and green pipes together
    • Turn the Okolab environment controller 3A and 3B back ON

This happens when the mixed-gas humidifier is overfilled. Bubbles created by the gas going through the humidifier can bring liquid into the gas feed line.

• Turn off the Okolab module and the water bath
• Remove your sample and store it properly
• Dry the incubation chamber with a clean tissue
• Carefully remove the cap of the humidifier glass bottle

• Remove distilled water from the humidifier

• Close the humidifier by replacing the cap
• Turn on the Okolab module and the water bath

This can happen during long experiments. The high humidity of the gas mixture condensates in the pipe between the humidifier and the incubation chamber.

• Pause your experiment
• Disconnect both ends of the yellow tube from the humidifier
• Drain the tube from any liquid
• Reconnect the yellow tube to the humidifier
• You can use a syringe or gas pressure to blow out any liquid from the incubation chamber cover

• Wipe any liquid with a tissue
• Reconnect the yellow tube to the incubation chamber 

• Yes. This is an inverted microscope designed to look at specimen in a dish or a multi-well plate
• The objectives are optimized to image through thin glass bottom multi-well plates
• You may also image specimen mounted between a slide and a 0.17mm thick coverslip
• For long timelapse, be aware of photo-toxicity

You may use a trick to warmup the incubation chamber faster. Using this method. you should reach a stable temperature within 30 minutes.

• Place your blank control in the incubation chamber
• Immerge the tip of the sample temperature probe in the blank
• Set the Okolab temperature Control Mode to Chamber (Settings>Temperature>Control Mode>Chamber>Save)
• Set the Okolab temperature to 50°C (Home>Temperature>50°C>Set)
• Check the temperature of the sample (Menu Magnifier>Sample Temperature). It should take between 10 to 15 minutes for the blank to reach 30°C. 

When the blank has reach the desired temperature

• Set the Okolab temperature back to 37°C (Home>Temperature>37°C>Set)
• Set the Okolab temperature Control Mode to Sample (Settings>Temperature>Control Mode>Sample>Save)
• Wait 10 to 20 minutes until the temperature stabilizes
• Then you can safely replace the blank with your sample
