Universal Shaker SM

Edmund Bühler Universal Shakers SM

Edmund Bühler Universal Shakers SM are rated for loads up to 30 kg.  Numerous, customer defined options make the Edmund Bühler SM 30 a shaker series that is more versatile than the competition. The user starts with the shaker base and builds a platform(s) to suit the unique needs of their laboratory. An additional option exists to purchase an incubator hood for climate controlled shaking.

Choosing the SM Shaker base

1. Motion: orbital, horizontal reciprocating, or both
2. Shaking speed: single continuous speed or up to five different user defined speeds

There are two SM 30 motor types: basic or control. The basic models have shaking speeds set by dials. The control models have computer controlled speeds, and their computer comes with either a control or USB connection.

SM 30 basic models operate at one user defined rotational speed. The control models are computer controlled using either a "control" or USB interface. The user may define up to five different time/shaking speed steps. Neither of these shaker models come with the racks pictured above. Only the rubber mat with platform is included as standard. Racks are sold separately. Hot plate shaker SM 30 AT control is also available.

SM Shaker Accessories

Accessories that are required to secure the vessels to the shaker are sold separately. Edmund Bühler offers two basic systems plus an additional additional story.

1. Rack System Combifix SM: Metal and rubber bars hold vessels in place on the shaker plate.
2. Universal tray SM: Holders for Erlenmeyer flasks and test tube holders screw into the shaker tray, which attaches to the shaker platform.
3. Mounts to attach a second story tray to the shaker platform.

SM 30 Rack systems mount on the metal tray with the rubber mat.

The Rack System Combifix trays are designed to accommodate larger Erlenmeyer flasks as well as larger, upright vessels that require greater security. The Combifix SM C system, unlike other rack systems for smaller Edmund Bühler shakers, comes with the clamping strips and spring strips needed to secure large separatory funnels.

Other Accessories: A Universal Tray and 2nd Story Rack

The Universal tray SM allows the user to screw in attachments for Erlenmeyer flasks and test tube holders. The tray and frame are sold separately.

Additional SM 30 accessories include a traditional universal tray and a 2nd story.

All four SM trays may be attached to the 2-story top frame SM. The Combifix top story trays come with an additional sliding plate. Two sliding plates may be mounted with each mounting set.

The TH 30 Incubator Hood

The TH 30 with additional shelf (left) and without (right).

The Incubator Hood TH 30 has a temperature range from +5°C above ambient to +50°C and can be combined with all universal shakers SM 30 or used as an independent unit. The height is sufficient for 2000 mL Erlenmeyer flasks. The incubator hood is equipped with a standard light and a UV light. Optionally, a cooling device for an external cooling system can be installed.

Safety cut-off of UV light and stop of the shaker when the front door is opened if combined with an Edmund Bühler Universal Shaker.

An additional heating device sufficient to reach 60°C (0052 105) and a cooling device to chill the interior to 5°C below (0051 581) ambient temperature can be installed at the customer's request. 

Further Applications in Biological Research

MSE Supplies has additional products for use in expressing recombinant proteins or natural products in cyanobacteria extraction. Postma and co-workers (2017) explored bead/ball milling as a gentle way of breaking open cyanobacteria cell walls. Cyanobacteria were grown, concentrated with a centrifuge, and milled for economically valuable biomolecules. The authors compared protein extraction from three different species of cyanobacteria. Four different sizes of yttria stabilized zirconia beads were used in this process: 0.3 mm, 0.4 mm, 0.65 mm, and 1 mm. The authors favored the smaller sizes for gentle harvesting of protein from cyanobacteria.

• 0.1 mm YSZ beads for DNA, proteins, and other molecules
• 0.6 - 0.8 mm YSZ beads for pharmaceuticals and foods
• 0.8 - 1.0 mm YSZ beads for foods, pharmaceuticals, DNA and RNA isolation
• 500 mL Nylon Roller Mill Grinding Jar
• 20L Nylon Roller Mill Grinding Jar
