Is stacking with Innova 44 possible?
Yes, that is possible. Stacking requires a base and the specific stacking kit. For a double stack the S44i must be placed on top of Innova 44 independent of orbit. For a triple stack: If two S44i with different orbits are stacked on one Innova 44, place the one with larger orbit in the middle. If one S44i is refrigerated place that one in the middle. Note that devices only run speed reduced: 2 devices stacked: 20 rpm – 300 rpm. 3 devices stacked: 20 rpm – 250 rpm. Due to speed limitation Balance master Calibration should not be run. Initial counterweight settings can be taken from the manual.
What is the maximum flask size I can use in the S44i?
Erlenmeyer flasks up to 5 L in size can be accommodated. If the static Incubation shelf is installed, flasks up to 1 Liter Erlenmeyer or 2.8 / 3 L Fernbach can be accommodated. General capacity tables are available in the operating manual
here.
Can I use all Eppendorf shaker accessories as well for the S44i?
Yes, all shaker accessories can be used with the S44i.
Can I use the S44i with sticky pad?
Yes, sticky pad can be used directly on the S44i Universal platform. The universal platform fits 9 sticky pads to be covered.
Can I run a double or triple stacked unit fully loaded and at full speed?
Yes, Balance Master function allows the optimal adjustment of the counterbalance to run all devices in a triple stack at maximum speed (300 or 400 depending on orbit) even with full load.
What is the maximum load on the platform?
The maximum load on the platform is 35.4 kg (78 lb).
What disinfection agents can I use to disinfect the S44i?
70 % Ethanol or Isopropanol or other suitable commercial disinfectant can be used for wipe disinfection the interior and exterior surfaces. For detailed information please refer to the operating manual at
www.eppendorf.com.
Can I upgrade my shaker later on with other options when I buy a basic non-refrigerated unit?
Yes, the options photosynthetic LED lights (on refrigerated units only), the static shelf and the window shade can be upgraded to a unit. Refrigeration cannot be upgraded later on.
What can I do when I have spillages to the chamber bottom?
Depending on the amount of spill open both refrigeration and reservoir drain to release liquid which may have entered the chamber bottom. The bottom of the chamber is protected by a base cover. This can be flushed also carefully from the front with water or disinfection solution. Make sure to flush bottom with drain open and prevent overfilling. The maximum reservoir volume is: 3 Liter. For full information please read the operating manual available at
www.eppendorf.com.
What is the temperature control range?
The non-refrigerated version allows temperature control between 5 °C above ambient up to 80 °C. The refrigerated version allows temperature control between 20 °C below ambient up to 80 °C (with a minimum of 4 °C).
What is the temperature uniformity?
The temperature uniformity is ±0.25 °C at 37 °C and 250 rpm.
Are there any limitations in temperature control with specific options installed?
No, also with photosynthetic LED lights running the maximum temperature is 80 °C.
Is there a possibility to increase the chamber humidity?
No, the device is not designed to create a humid chamber environment nor work with a humid chamber environment. The base cover is only for catching potential spillages, protection of the drive and cleaning purposes.
How long does the Balance Master (BM) calibration take?
Balance Master calibration must be performed on one device at a time with no other device running the speed function. The calibration can take up to 60 minutes per device. It is typically much quicker with a single device and with a double stack. Correct installation and leveling is very important for quick and successful Balance Master calibration. Balance Master has to only be done one time during installation or when shaker is relocated to another position.
How long does the Balance Master optimization take?
The Balance Master optimization does take maximum 10 minutes.
What is the benefit of Balance Master?
The Balance Master function assures that the platform is always in perfect counterbalance. Any imbalances will be immediately detected and with Balance Master Optimization the counterbalance can be easily adjusted to optimum. Balance Master facilitates full flexibility in load and speed, reproducible shaking and minimal wear out of shaker components.
How often do I have to do Balance Master Optimization?
Only if the device gives a speed alert. The counterweight is already optimized for the position by the initial calibration procedure (e.g. ground, middle of the stack). It may be necessary to adjust the counterbalance when very high or imbalanced loads are run at high speeds.
Do you recommend to adjust the counterbalance every time after change loads?
No, the shaker is optimized with initial calibration to run most load/speed scenarios. Balance Master Optimization must only be done when the shaker notifies the user of an imbalance (alarm notification via display).
Can I use the Balance Master function when the S44i is stacked with an Innova 44?
Devices only run speed reduced speed: 2 devices stacked: 20 rpm – 300 rpm and 3 devices stacked: 20 rpm – 250 rpm. When using in a mixed combination with Innova 44 we recommend using the tables in the operating manual for initial average adjustment of the counterweight. Calculate the platform weight plus the average amount of weight. Balance Master optimization will not work not optimal as it is not calibrated and may give wrong results
Can I upgrade the Innova S44i with photosynthetic lights?
Yes, the LED light option can be retrofitted. All refrigerated versions can be later upgraded with the LED photosynthetic light option by our Eppendorf Service team.
What is the maximum flask size I can use when the photosynthetic lights are installed?
There is no limitation in flask Size, the maximum flask size stays 5 Liter.
What type of photosynthetic lights do you offer?
We offer LED lights with a maximum light intensity of 150 PAR (µmol m-2 s-1). The uniformity across the platform is ±10%.
What is the photosynthetic light intensity in µmol m-2 s-1 and in Lux?
The maximum light intensity is 150 µmol m-2 s-1 or 10,000 Lux. The minimum light intensity is is 15 µmol m-2 s-1 1000 Lux.
What is the minimum and maximum light intensity?
The maximum light intensity is 150 µmol m-2 s-1 or 10,000 Lux. The minimum light intensity is is 15 µmol m-2 s-1 1000 Lux.
Are there any limitations when using the photosynthetic lights?
The unit must be a refrigerated unit to compensate the additional heat in chamber.
What is the average rated life of the LED light and can I replace single bulbs?
The LED light bank was long-term tested for three years at full intensity and in an 80°C chamber and did not show any degradation. Replacement part will be the whole bank.
Is the light intensity adjustable?
The light intensity is adjustable between 10 - 100 % in increments of 1 %. Minimum = 15 PAR (µmol m-2 s-1), maximum = 150 PAR (µmol m-2 s-1). The control and intensity adjustment can be done easily via the main display and requires no extra control element(s).
What spectral range do the lights have?
The wavelength spectrum is between 400 nm – 700 nm. To see full spectrum click

What is the uniformity throughout the platform?
The uniformity across the platform is ±10% from the PAR value.
Are the photosynthetic lights programmable with a timer?
Yes, the integrated programming function offers full flexibility. Different light intensities or on/off phases in a row can be programmed. Cycling of steps or whole programs e.g. to imitate circadian rhythms is also possible.
