With this new option for the ISF4-X incubator shaker, up to two shaking units (out of four) can run with shaking frequencies up to 1000 rpm at 3 mm shaking diameter. This combination is specifically recommended for users of 96 deep-well microtiter plates with high filling volumes (e.g., cell culture in deep-well plates). The shaking table is specially designed for up to 20 microtiter plates, and it is also suitable for the Duetz system. The shaking diameter is user-adjustable to any other standard configurations of 6, 9, 12.5, 19, 25, 50, and 70 mm.

The option 3 mm/1000 rpm is only available for ISF4-X with active cooling.

The temperature accuracy, absolute for this option 3mm/1000rpm is +/-0.45°C (at 37°C).

Existing ISF4-X incubator shakers can be retrofitted with this option.

The ceiling of any Kuhner incubator shaker can be fitted with LED modules for the cultivation of phototrophic organisms. The control module allows full programming of night/day cycles and variable light intensity.

The pull-out table is designed for the ISF1-Z and ISF4-X incubator shakers as well as the Rack System. This remarkable device makes loading and unloading trays much easier.

The dual table is an easy and economical way of doubling the shaking capacity. The dual shaking table consists of two levels. Each level will accept an E (420 x 420 mm), EX (500 x 420 mm) or F (800 x 420 mm) size tray.

The dual table is available with a fixed distance between the two levels of either 120, 160, 180, or 200 mm. At the maximal distance of 200 mm the lower level accepts 125 mL, 250 mL, and 500 mL Erlenmeyer shake flasks.

However, with the dual table the shaking speed is limited to 200 rpm at a shaking diameter of 50 mm (all other maximum shaking frequencies, dependent on the shaking diameter, can be withdrawn from the ISF4-X manual).

The TabCom option from Kuhner consists of a cable for power and data with the connection port integrated in the shaking table (see pictures below). A cable guide prevents the cable breaking and ensures secure data recording. The flexibility of TabCom means online measurement systems can be easily integrated.

IQ-OQ (Installation Qualification and Operation Qualification) is an equipment qualification according to GMP procedure. Kuhner offers this service which can also be carried out at the customer’s premises.

The universal tray can be fitted with clamps for Erlenmeyer flasks, test tube holders, microtiter plates, or custom made holders to suit your requirements. Rearranging these clamps and holders is quick and simple.

ISF4-X with Universal trays FU,

fitted with Ultra Yield flasks (2500 mL) from Thomson

A special F-size universal tray (800x420mm) is now available to shake large Erlenmeyer flasks. It is ideal for cell culture.

This tray allows parallel shaking of 7 x 3L Corning Fernbach culture flasks or 7 x 5L Thomson Optimum Growth flasks at a maximum orbital diameter of 50mm. The FUM-V has no handles and a V support underneath the tray raises it above the clamping mechanism creating more space for flasks.

Clamps must be ordered separately. (Order number: 101425) 

The clamps are riveted onto these trays and cannot be removed. They offer maximum stability and will often hold a larger number of flasks than universal trays. These trays are available in a variety of flask clamp sizes from 25 to 6000ml. 

Kuhner has designed trays specifically for microtiter plates. Handles at the front of the tray open and close the special clamping mechanism allowing plates to be loaded and unloaded. Trays of different heights (22, 47 and 77mm) allow the stacking of up to four microtiter plates. The tray is suitable for all types of plates (deep well, low well, 24, 48 and 96 well).

Kuhner has designed a new tray for microtiter plates. This tray is fitted with springs which allows each well plate to be loaded and unloaded individually. The tray is available in three sizes: E (420x420mm), EX (500x420mm) and F (800x420mm).

This new tray is particularly suitable for the special holder with filter lid for deep well microtiter plates.

F-tray (800 x 420 mm)

Kuhner has designed a new F-size tray (800 x 420mm) which is ideal for cell culture. The F-V5000/7 tray allows parallel shaking of 7 x 3L Corning Fernbach culture flasks, 7 x 5L Corning Erlenmeyer flasks or 7 x 5L Thomson Optimum Growth flasks. Flasks are held in position by pins and are easily placed on the tray and removed just as quickly.

This tray has been designed for easy cleaning and efficient handling of samples.

The whole tray is covered with a rubber mat and is particularly suitable for shaking containers at low speed (e.g. blood bags).

A tray fitted with sticky strips is especially useful for flasks shaken at low speeds (up to 200rpm). The flask is placed directly on the sticky strip without the need for any other support. Flasks of all sizes can be used. Sticky strips are available individually or in sets and can also be supplied already fitted to a tray. The E-size tray accepts four strips, while the EX-size tray requires five strips and the F-size tray eight strips.

The PC-plate increases the adhesion of the sticky strips. This is particularly helpful if using flasks >500ml.

The dual tray offers two shaking levels and doubles the capacity. It is available in EXU, EX, FU and F size and the upper tray can be removed.
Please note the shaking speed is limited.

This tray offers an alternative to both clamps and sticky mats and is ideal for tall containers. The tray is covered with a rubber mat and has an upright at each corner. The F-tray is fitted with six cross supports. These support bars securely clamp containers.

Kuhner has also designed a special tray for shaking separating vessels. This very flexible tray can take vessels of various sizes. It is also possible to add a second layer and double the capacity. Movable retaining rods allow vessels to be installed easily.

The pin-clamps are ideal for cleanrooms and areas where sticky mats or other standard clamps are not suitable. The clamps have been designed for easy cleaning and efficient handling of samples. The stainless-steel pin-clamps are compatible with all Kuhner universal trays. The shaking speed is limited to a maximum of 180 rpm at 50 mm shaking diameter.

The ISF4-X incubator shakers can be fitted with a shelf allowing cultivation in petri dishes. One or two shelves can be placed above the shaking table and fixed to the chamber walls with four screws. More.

To reduce evaporation from shake flasks or microtiter plates a Teflon coated water bath can be placed inside the incubator. This water bath is not fitted with an automatic water supply and must be topped up manually
