The innovative ISF1-Z Peltier uses long life peltier elements for precise heating and cooling and also for humidity control. This eco-friendly concept makes coolants or compressors unnecessary. The humidity control of the ISF1-Z Peltier is able to humidify and dehumidify up to 50% compared with the ambient relative humidity. 

This versatile new option for the ISF1-Z Peltier incubator shaker can shake at 3mm orbit diameter with speeds up to 1000rpm. This combination is recommended for users of 96 deep-well microtiter plates with high filling volumes. The 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 3, 6, 9, 12.5, 19, 25, 50, and 70mm. It runs smoothly and quietly and can be stacked up to three machines high. There are special technical add-ons that ensure uniform temperature distribution in the incubator chamber. It comes with our standard 5-year standard warranty guaranteeing quality and durability.

As in a biological safety cabinet, the chamber of a Kuhner incubator shaker can also be sterilized with an integrated UV lamp. The lamp is situated to maximise irradiation of the chamber and shaking table. The UV lamp has a clearly marked external switch and when the door is opened, the UV-lighting is automatically switched off.

Available for light sensitive medium or organisms. Any Kuhner incubator shaker can be delivered with blackened windows to prevent unwanted daylight or UV radiation inside the incubator.

Check out the Kuhner EquipNote "Light protection for Kuhner incubators".

The ISF1-Z incubator shaker with automatic door is designed for easy handling and maximum comfort. The automatic door is activated by pressing a button on the incubator shaker. A foot switch option is also available.

Labelling plates are now available for the ISF1-Z foot switch that is used with the automatic door option. For a  stack of 2x or 3x ISF1-Z incubator shakers with the automatic door feature, these labelling plates will allow the user to easily identify which foot pedal corresponds to each machine. 

This option includes a 10.1-inch touchscreen with our Kuhner Insight Software. The touchscreen has been designed for simple operation, monitoring and programming. It can also be retrofitted to existing incubator shakers. More.

The pull-out table is designed for the ISF4-X and ISF1-Z 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 lower level of the dual table is the standard Z-table or a pull-out table. Combining the pull-out feature (only for the lower platform) with the dual-level function allows faster access to the bottom level for easy handling and better ergonomics.

The distance between the two levels of the dual table is user-adjustable; the maximal distance between the two levels is 200 mm. At this distance the lower level accepts 125 mL, 250 mL, and 500 mL Erlenmeyer shake flasks. If required, the user can also easily remove the upper level completely to use the incubator shaker for flasks or vessels taller than 500 mL Erlenmeyer flasks.

However, with the dual table the shaking speed is limited to 200 rpm at a shaking diameter of 50 mm, 250 rpm at 25 mm, and 300 rpm at 12.5 mm (all other maximum shaking frequencies, dependent on the shaking diameter, can be withdrawn from the ISF1-Z manual).

The ISF1-Z is completely made of stainless steel. It can either be painted white or have a processed stainless steel look.

Kuhner TOM (Transfer-Rate Online Measurement) measures online oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR) and the respiratory quotient (RQ) in up to 16 individual shake flasks for better process understanding and informed process development. TOM is easily installed in any Kuhner shaker and can be operated with various flask types and sizes including single use shake flasks. Kuhner TOM has zero footprint on the shaker tray as it is mounted above (see picture below). More.

To prevent accidental operation of the controllers, the panel can be protected by a perspex cover.

Kuhner CleanShield is a disposable inlay for the newly designed water bath-Z. The CleanShield simplifies the cleaning process, saves users’ time, and provides a clean environment in our shaker incubators. The open water bath has been designed to allow a quick replacement of the CleanShield and a good visual inspection. Both aspects contribute to a safe and reliable performance of the conducted cultivations. The process of changing the sterile Kuhner CleanShield inlays takes just five minutes and cultivation can resume immediately after. Harsh cleaning agents might leave residues or vapors in the incubator that could negatively impact your cultures. The CleanShield eliminates this risk and protects the water bath which results in less maintenance and an increased lifetime of the shaker incubator.

The ISF1-Z comes with two water bath options:

• Standard water bath-Z

• Water bath-Z for Kuhner CleanShield (Option: 104711)

The standard water bath-Z can be converted to a water bath-Z for Kuhner CleanShield, by using the retrofit set 104488.

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.

FU-tray with 8x 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 this tray and cannot be removed. It offers maximum stability and will often hold a larger number of flasks than an universal tray.  

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 trays are available in three sizes and 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.

For a comfortable working height Kuhner offers floor stands for the ISF1-Z and LT-X incubator shakers. These are available in a choice of 400mm or 765mm high. 

Floor stands with wheels are available for the ISF1-Z and LT-X incubator shakers. These stands enable the user to move the machines easily. However, the shaking speed is limited.

The universal stacking adapter allows other equipment to be placed on top of an ISF1-X/Z  incubator shaker, providing an additional work surface. Create more space in your laboratory with the universal stacking adapter.

This stacking adapter is designed for stacking a LT-X on an ISF1-X/Z incubator shaker. Extra work space on the adapter allows room for flasks or a small machine, as well as the LT-X, thus creating a greater working area.

The user-friendly Kuhner Insight software was developed for supervision, monitoring, and recording of data. The software is easy to operate. More.

Kuhner has designed a new light shade plate for the ISF1-Z incubator. This plate is easily placed in front of the door window to prevent radiation affecting the contents of the incubator chamber. It protects light sensitive media from UV, artificial and/or daylight.

Simply lift up the light shade plate to look at the cultures without opening the incubator door. When light protection is no longer required, the plate is easily removed.

Check out the Kuhner EquipNote "Light protection for Kuhner incubators".

You have a low ceiling or low hanging ceiling lamps in your laboratory but want to fit an ISF1-Z triple stack in the room?

With a door opening limiter for the upper shaker (order n° 108602), the maximum height of an ISF1-Z triple stack can be reduced by about 8 cm (from 2536 mm to 2457 mm). The installation of two small spacers into the door hinges reduces the height of the opened door noticeable but without constraining the access to the incubator chamber.

A further reduction of the maximum height is also possible on customer request. Please feel free to contact us via office@kuhner.com.
