IKA RC 2 GREEN basic Circulation Cooler, R290, 800 W Cooling Capacity, Down to -30 °C, 0025004186

Anyone who lets cell cultures or microbiological samples shake unattended overnight needs temperature control that also works below room temperature. The IKA KS 4000 ic control combines an orbital shaking motion with PID-controlled heating up to 80 degrees Celsius and a built-in cooling coil. Together with an externally connected circulation chiller, the 90 litre internal chamber reaches temperatures down to room temperature minus 10 degrees. Without this chiller, the device works as an incubating shaker with heating, entirely without active cooling.PID control from minus 10 to 80 degrees CelsiusTwo PT1000 temperature sensors and an integrated PID controller hold the set temperature with a setting accuracy of 0.1 kelvin. With a vessel containing 0.5 litre of water, 22 degrees room temperature and 37 degrees set temperature, the control accuracy is ±0.5 kelvin and the temperature stability is ±0.05 kelvin. With 0.2 litre of water at 25 degrees room temperature and 37 degrees set temperature, the stability falls to ±0.1 kelvin. Spread over five vessels of 0.5 litre each, the homogeneity in the interior is ±0.5 kelvin. A large LED display shows speed and temperature, and an additional connection socket in the working space takes a further PT1000 sensor, for example the supplied PT 1000.60 made of stainless steel.Cooling coil and external circulation chiller belong togetherThe KS 4000 ic control has no compressor of its own and no refrigerant circuit of its own. The built-in cooling coil needs an externally connected circulation chiller, and IKA names models such as the RC 2 lite, the RC 2 basic or the RC 2 control for this. LT Laborhandel also carries the IKA RC 5 control for this purpose, with 1400 watt cooling capacity down to minus 30 degrees. Without a connected chiller, the temperature range remains limited to room temperature up to 80 degrees. Anyone who knows from the outset that work will only be done above room temperature saves the chiller and chooses the otherwise identical KS 4000 i control (ident no. 0003510000) without a cooling coil.20 kilograms shaking load at 20 millimetre orbitThe orbital motion has a shaking orbit of 20 millimetres and carries up to 20 kilograms of shaking material including attachment. The speed ranges from 10 to 500 revolutions per minute, adjustable in steps of 1 rpm, with a deviation of ±5 rpm. The motor draws 82 watts and delivers 24 watts, designed for a duty cycle of 100 per cent. The electronic timer covers 0 to 999 hours, optionally in timer or continuous operation, with a 7-segment LED display for the remaining time.Safety and everyday operationIn the event of a fault, the device switches off automatically, and likewise when the hood is opened during operation. The controls have an antimicrobial coating, and a drip tray with a drain hose at the back of the device catches spilled liquid. Via the RS-232 interface, the KS 4000 ic control can be connected to the laboratory device software labworldsoft, for documenting temperature, speed and time. The housing is made of powder-coated sheet steel, the front foil of polyester.Typical applicationsMicrobiological cultures with a cooling requirement below room temperatureCell cultivation with tight tolerances for temperature stability and homogeneityUnmonitored shaking operation overnight or over the weekendDocumented temperature control via labworldsoft in quality-assured laboratoriesTechnical detailsType of motionorbital, shaking orbit 20 mmPermissible shaking load (incl. attachment)20 kgSpeed range10 to 500 rpm, steps 1 rpm, deviation ±5 rpmMotor power input / output82 W / 24 WHeating power1000 WTemperature range (with external circulation chiller)Room temp. -10 °C to 80 °CControl accuracy / stability (0.5 l, 37 °C)±0.5 K / ±0.05 KHomogeneity (5 vessels 0.5 l, 37 °C)±0.5 KTimerelectronic, 0 to 999 h, timer and continuous operationWorking area internal chamber (W x H x D)440 x 440 x 352 mmTotal volume internal chamber90 lMaterial housing / front foilPowder-coated sheet steel / polyester foilRS 232 interfaceyesProtection classIP 30 (DIN EN 60529)Dimensions (W x H x D)580 x 520 x 750 mmWeight55 kgConnected load230 V, 50/60 Hz, 1120 W, fuse 2x T10A 250VScope of delivery1 x KS 4000 ic control1 x PT 1000.60 temperature sensor, stainless steel4 x clamping screws short (for fixing the attachment)2 x clamping screws long (for fixing the attachment)Attachments such as the universal attachment or retaining clips are not included and must be ordered together with the device to suit the application. An external circulation chiller for the cooling function is likewise not part of the scope of delivery.Selection guide and serviceIf you need a smaller internal chamber, the KS 3000 ic control (ident no. 0003940100) offers the same cooling principle with a built-in cooling coil, but only 50 litres of volume, a shaking load of up to 7.5 kilograms and an additional USB-B interface. IKA grants a manufacturer's warranty of 2 years for the KS 4000, extended to 5 years with registration at ika.com/register within 90 days of purchase. As an electrical device, the KS 4000 ic control falls under the WEEE directive and must not be disposed of with household waste at the end of its life. Via the procurement service of LT Laborhandel, circulation chillers, attachments and further accessories can be ordered together to suit the application.

It is not possible to maintain the temperature of samples below room temperature using a heater alone. The IKA KS 3000 ic control therefore has a built-in cooling coil with connections for an external cooling unit; IKA cites the RC 2 basic or RC 2 control as examples. With cooling, the temperature range extends from room temperature minus 10 K to 80 °C, provided the inlet temperature is above 3 °C. The incubation shaker performs circular shaking with a 20 mm stroke at 10 to 500 rpm and can hold up to 7.5 kg.Heating and coolingAn integrated PID control system operates with two PT-1000 sensors; the heating power is 1000 W. The setpoint temperature is adjusted and displayed in increments of 0.1 K. With a sensor in the vessel, the control accuracy is ±0.5 K (1 vessel containing 0.5 l of water, 22 °C room temperature, 37 °C). Temperature stability is ±0.05 K (1 vessel containing 0.5 l, room temperature 25 °C, 37 °C), whilst temperature homogeneity across five vessels, each containing 0.5 l, is ±0.5 K. There is a connection socket for an additional sensor in the working chamber. A stainless-steel PT 1000.80 is included in the Scope of delivery.Interior, hood and safety featuresThe inner chamber measures 330 x 330 x 258 mm and has a volume of 50 l. The lid is made of PMMA, whilst the housing is made of powder-coated sheet steel. The unit stops automatically when the lid is opened and switches itself off in the event of a fault. The control elements have an antimicrobial coating to reduce bacteria. A drip tray with a drain hose at the rear collects any liquid. Speed and time are shown on a large LED display. The timer ranges from 1 second to 999 hours; alternatively, the unit can run continuously.Typical applicationsShaking temperature-controlled samples for hours in unattended operationIncubation at a constant temperature, for example at 37 °CTemperature control below room temperature with a connected cooling unitDocumented runs via RS 232, USB-B and labworldsoftShaking of vessels of various sizes using clamps or a universal adapter, up to 7.5 kgWith or without a cooling coilIf you only need to heat from room temperature plus 5 K, you can opt for the KS 3000 i control. It has the same chamber, the same speed and the same shaking weight, but weighs 35 kg instead of 37 kg. For heavier batches requiring a 20 kg shaking load and a 90-litre chamber volume, the KS 4000 i control is available.ModelTemperature rangeShaking weightInternal chamberWeightKS 3000 ic control (this unit)Room temperature minus 10 K to 80 °C (with cooling)7.5 kg50 l37 kgKS 3000 i controlRoom temperature plus 5 K to 80 °C7.5 kg50 l35 kgKS 4000 i controlRoom temperature plus 5 K to 80 °C20 kg90 l50 kgTechnical detailsMotion and strokecircular, 20 mmShaking weight including attachmentup to 7.5 kgMotor power input / output45 W / 10 WRotational speed10 to 500 rpm in 1-rpm increments, deviation 1 %Timer1 s to 59,940 min, 7-segment LED, continuous operation possibleDuty cycle100 %heating power1,000 WTemperature range (flow temperature above 3 °C)Room temperature minus 10 K to 80 °CSetpoint temperature adjustmentin increments of 0.1 KControl accuracy with sensor±0.5 K (1 vessel containing 0.5 l of water, room temperature 22 °C, 37 °C)temperature stability±0.05 K (1 vessel, 0.5 l, ambient temperature 25 °C, 37 °C), ±0.1 K (0.2 l water, ambient temperature 25 °C, 37 °C)Temperature homogeneity±0.5 K (5 vessels, 0.5 l, ambient temperature 25 °C, 37 °C)CoolingBuilt-in cooling coil with connections for external coolingInternal chamber (W x H x D)330 x 330 x 258 mm, 50 lMaterialsHousing: powder-coated sheet steel, cover: PMMA, front panel: painted ABS, front film: polyesterInterfacesRS 232, USB-BDimensions (W x H x D)465 x 430 x 695 mm, 875 mm high with the cover openWeight37 kgOperating environment15 to 32 °C, up to 80 % relative humidityProtection classIP 30 (DIN EN 60529)Mains connection230 V, 50/60 Hz, 1120 WScope of delivery1 x IKA KS 3000 ic control incubation shaker1 x PT 1000.80 temperature probe, stainless steel4 x clamping screws, short1 x USB A-to-B cableLids and the external cooling unit are not included in the Scope of delivery.
