IKA Trayster basic Overhead Shaker, Fixed Speed 20 rpm, 2 kg Load, 0004005000

Anyone who wants to gently mix blood samples or other biological samples for hours in shift operation does not need menus or a digital display, but a device that reliably performs one single movement. That is exactly what the IKA Trayster basic does: an overhead shaker with a fixed speed of 20 rpm, without a display and without a timer. The tube or bottle rack rotates evenly around one axis, and the samples are mixed gently instead of being foamed. The device is designed for continuous operation at 100 per cent duty cycle and for use in incubators or cold rooms between 4 and 50 °C.

Fixed speed without setting option

The Trayster basic runs at a constant 20 rpm, there is no speed control and no timer. In a basic model this fixed setting is not a defect but a consequence of the intended use: for many routine applications with blood samples or similar biological materials, one single, proven speed is sufficient and fine adjustment is unnecessary. The device runs as soon as it is switched on and is suitable for 100 per cent duty cycle in continuous operation. If you need different applications with variable speed and SOP documentation via a timer, you will find the suitable comparison with the Trayster digital further below.

Load, design and accessory mounts

With dimensions of 460 x 180 x 140 mm (W x H x D) and a weight of 1.6 kg, the Trayster basic takes up little space in the laboratory or cold room. The permissible shaking load including attachment is a maximum of 2 kg. For the tube rack, IKA lists the test tube inserts TR 1 to TR 4 as accessories, suitable for different tube sizes. These attachments can easily be removed for cleaning between different sample series. The housing is protected to IP 21 (DIN EN 60529), the permissible relative humidity is 80 per cent, and the ambient temperature range of 4 to 50 °C also covers cold rooms and incubators.

Typical applications

The Trayster basic covers applications where a fixed, proven speed in continuous operation is sufficient:

• Gentle mixing of blood samples and other biological samples by even overhead rotation
• Separating and mixing powdered and liquid samples in tubes up to 50 ml
• Use in incubators and cold rooms at 4 to 50 °C ambient temperature
• Continuous operation with 100 per cent duty cycle for uninterrupted processes
• Routine mixing without setting effort at workstations with frequent changes of user

Technical details

Scope of delivery

• 1 x IKA Trayster basic overhead shaker (basic unit)
• 1 x plug-in power supply (input 100 to 240 V, output 24 V=)
• 1 x operating instructions

Tube attachments such as the test tube inserts TR 1 to TR 4 are accessories and are not included in the scope of delivery of the basic unit.

Comparison with the Trayster digital

Alongside the Trayster basic, IKA offers the Trayster digital (ident no. 0004006000) as a second model of the same series. The Trayster digital has a continuously adjustable speed of 5 to 80 rpm, an LED display and a countdown timer from 1 second to 99 hours 59 minutes, plus a shaking time counter and an error code display. The Trayster basic described here does without all of these functions in favour of a single fixed speed of 20 rpm without any display. Both models share the type of motion, the load of 2 kg and the ambient temperature range of 4 to 50 °C. If you need reproducible, documented speeds for SOPs or want to mix samples at different speeds, you are better served by the Trayster digital. For pure continuous operation at a fixed speed, the Trayster basic is sufficient.

Individual requirements & procurement service

For the Trayster basic, IKA lists the test tube inserts TR 1 to TR 4 as accessories as well as an EU declaration of conformity for download. If you need a rocking or tilting motion with an adjustable tilt angle instead, you will find further devices from IKA in the stirring and mixing technology section, for example the IKA Rocker 3D digital wobble shaker with an adjustable angle of 0 to 150 degrees and likewise 2 kg load. For questions about attachments, certificates or choosing the suitable model, the procurement service of LT Laborhandel will support you.
