When working with live cells on a microscope it is convenient to have an incubator close to the scope. It is beneficial for temporary storage of chambers (to keep them pre-warmed), specimens or media used for perfusion, and most importantly a clean, dry, safe place for heated objectives when not being used. Bioptechs recommends the Boekel Warmer because its small size, light weight. It is not humidified making it an ideal warmed objective storage device. The warmer measures 8" x 8" x 7", operates on 20 watt AC and is small enough to be mounted close to the microscope for temperature controlled perfusion media storage during experiments.
