The IKA AS 4000.1 uses adjustable clamping rolls to create a manufacturer-approved vessel-holding setup on KS 4000 i control and KS 4000 ic control incubator shakers. Choose the arrangement around vessel geometry, working fill, total moving load and the method’s speed requirement.

Attachment only. Catalog 0008022200 is not an incubator shaker, a set of flasks or a complete culture system. The parent instrument and vessels are separate purchases. This is the companion holder option for the attachment-required KS 4000 instrument, not a duplicate shaker order.

Use the universal-roll format when a suitable adjustable restraint is preferable to a separately selected fixing-clip or dish attachment. Verify the current manufacturer packing configuration if a particular roll count or maximum-count layout is essential.

For suitable mixed vessel shapes

Choose adjustable rolls when the actual vessel geometry can be securely restrained within the manufacturer’s arrangement guidance. Universal does not mean every shape, fill or center of gravity is safe at every speed.

For a KS 4000 setup that needs its holder

The instrument’s current scope excludes vessel-holding attachments. AS 4000.1 supplies a separately ordered holding format; confirm the actual parent model rather than treating it as a universal accessory for every IKA shaker.

For a method with a defined load and layout

Vessel count is only one part of the choice. Count the attachment, vessels and contents in the total load, secure and balance the arrangement and choose a speed supported by the shaker instructions.

One manufacturer-defined AS 4000.1 attachment

• Order code 0008022200, AS 4000.1 universal attachment.
• The clamping-roll holding format documented for KS 4000 i and KS 4000 ic control.
• Parent shaker, vessels and sample contents are not included in this order.
• Current packing counts should be confirmed if the chosen layout requires a specific number of rolls or spare fasteners.

The manufacturer states that the screws used to fasten the attachment onto the shaker are supplied with the KS 4000 instrument. Those mounting screws are not the same question as the current roll-fastener or spare-parts packing configuration.

A historical manufacturer brochure documents a six-roll configuration, but that is not presented here as a newly verified current packing promise. Some current maximum-count layouts need an additional roll.

Adjustability supports selection, not an automatic fit guarantee

Position and secure the clamping rolls under the manufacturer’s assembly instructions for the vessel arrangement. Vessel shape, diameter, height, fill and center of gravity matter; a nominal flask size alone cannot establish a safe setup.

Inspect the holder and fasteners, mount it on the correct parent instrument and secure the vessels. Disconnect the instrument from mains before fitting accessories and wait for the shaker to stop completely before handling the moving assembly.

This page does not promise a specific attachment material grade, autoclave tolerance, sterile condition or universal chemical resistance without source evidence. Use the actual manufacturer cleaning and care instructions for the attachment and shaker.

The holder consumes part of the load allowance

The parent KS 4000 manual gives standard guidance of 6 kg at up to 500 rpm, 12 kg at 400 rpm, 15 kg at 300 rpm and 20 kg at 120 rpm. The total includes the selected attachment, vessels and contents.

Do not take the 20 kg maximum and advertise it as 20 kg of liquid on top of the holder. Secure and balance the layout, start at a suitable low speed and reduce the frequency if operation becomes uneven.

The shaker’s disturbance protection does not replace restraint checks or guarantee spill-free operation. A nominal holder mass is also not a confirmed packed shipping weight.

Example: 250 mL Erlenmeyer flasks

The current manufacturer guide illustrates 12 nominal 250 mL flasks with four rolls for this attachment family. This is a layout reference, not a 3 L working-liquid batch or an automatic maximum-speed approval.

Example: 500 mL or 1 L Erlenmeyer flasks

The guide illustrates nine nominal 500 mL flasks with four rolls, or six nominal 1 L flasks with three rolls. Actual vessel geometry, restraint, working fill, balance and load-dependent speed still govern the method.

Check the rolls needed for dense layouts

The 54 × 25 mL example requires seven rolls in the current guide. Do not assume every published maximum-count arrangement can be achieved with the packing configuration shown in an older brochure or photograph.

Build a complete, specified purchasing path

• Confirm KS 4000 i control or KS 4000 ic control as the parent model.
• Select the vessel type, count and working fill, then confirm the required roll/layout configuration.
• Mount the attachment using the correct instrument-supplied mounting screws and manufacturer procedure.
• Secure and balance the loaded vessels; count the full moving assembly against the load guidance.
• Choose suitable speed and temperature on the parent instrument and check stable operation under the method’s safety controls.

The attachment itself does not heat, cool, shake or control temperature. Choosing AS 4000.1 does not convert an i instrument into an ic cooling configuration.
