Gerhardt Shakers

Laboshake Programmable shakers offer complete operational variability: 9 different shaking programs. No need to adjust settings for individual users 9 steps per program, set for speed and time. For even the most complicated procedure Speed settings from 0 to 200 rpm, with standard 50 mm throw allows for optimal shaking conditions Time can be set in seconds, minutes and hours Separate LED displays allows shaking time and speed to be called up and changed during any procedure. Allows manual intervention without affecting the program Optional breaks can be set into any program

Applications

• Plastic housing improves resistance to corrosion.
• Stable base plates mean that shakers can handle heavy loads up to 30 kg for long continuous operation.
• Laboshake can operate in varying temperature and humidity conditions allowing reliable operation in incubators, cold rooms and hot rooms.

Reliability

• Mixing of liquids
• Dissolve poorly soluble salts
• Create emulsions
• Homogenization of suspensions
• Liquid/liquid extractions

Versatility
The basic shaker models have a wide range of optional accessories to suit virtually all laboratory applications.

• Carrier plates for large numbers of flasks or bottles.
• Two and three storey frame sets to save precious bench space.
• Incubator chamber for temperature dependant applications.

Models
There are two basic models of shaker. Together with the extensive range of accessories, these shakers easily satisfy the extensive requirements of chemical, biological, or microbiological research. Heavy loads are handled with the same ease as varying temperature or humidity conditions. Both models can handle loads up to 30 kg. Delivery of the basic model includes 4 vertical rods 150 mm long to accept the variety of attachments (spanner included for easy assembly), mains cable and an instruction manual. A large variety of accessories is also available.

Shaking frequency 20 - 200 min-1, amplitude 50 mm, time and speed can be programmed, shaking platform 540 x 370 mm, max. load 30 kg.

Thermoshake Incubator shaker Thermoshake VT and TH The extensive range of Gerhardt shakers now includes additional models: 4 new incubating shakers. All models havea new incubating chamber, which ensures a high stability of temperature. Thanks to built-in Peltier elements, models VTO 500 and VTL 500 assure a precise control range of 10 °K below room temperature to a maximum of 60 °C. Models THO 500/1 and THL 500/1 offer a precise range without cooling function of 5 °K above room temperatureto 60 °C.

Advantages

• Heat insulated temperature chamber
• Saving energy thanks to minimal heat loss
• High stability of temperature Operation
• Stores up to 9 programs
• RS 485-interface (read out of temperature data possible)
• Incubator and illumation of the interior can be set separately

Extensive accessories

• Saving bench space by using two tiers console
• Accessories to attach bottles, separatory funnels, Erlenmeyer flasks and many more

Model VT with cooling

• Quiet operation thanks to Peltier-element
• Since no cooling agent is necessary, extremely environmental friendly

Rotoshake 12 Powerpack with high safety standard Elution Shaker Rotoshake is especially suited for the treatment of soil samples acc. to DIN 38414-part 4 respectively EN 12457-4. Thanks to a completely new drive mechanism, up to 12 x 2000 ml glass or plastic bottles can be handled easily in continuous operation.

Construction - Intelligent power transmission
The elution shaker is equipped with a unique roller drive with an extremely powerful and maintenance free motor. The rotating cylinder is kept on two robust rollers with guide way only due to its self-weight. This perfect power transfer ensures an even and silent rotation even when it is loaded unbalanced. Thus, you can shake various types of bottles with different weights simultaneously. Rotoshake can be used in any laboratory for continuous operation with heavy loads without any problems.

Safety - demands to a certified laboratory
All moving parts are protected behind the protective hood, which is closing off the instrument. This hood is linked to a safety switch. As soon as the protective hood is lifted off, the rotation is stopped automatically. This feature offered by Gerhardt is far more than any national or international safety standard for laboratories is asking for.

• Protective hood ensures a very high safety standard
• Steady rotation even with unbalanced load
• Robust roller drive with an extremely powerful motor
• Different sizes of bottles can be used in only one rotation cylinder
• Easy handling of loading and de-loading: the rotation cylinder stops automatically in the respective position
• Shaker can take up to 12 x 2000 ml bottles
• Easy exchange of rotating cylinder
• As an option, various sizes of rotation cylinders are available
• Up to 9 programs can be stored and called up again
