Product information "IKA Rotary Evaporator RV 8 V, Hand Lift Set with Heating Bath up to 180 °C and Glassware, 0010003482"
When a distillation needs a heating bath temperature above 99 degrees Celsius, for example with higher-boiling solvents or oil bath operation, a simple water heating bath is no longer sufficient. The IKA RV 8 V rotary evaporator is designed for exactly this case: the RV 8 drive unit with manual hand lift works together with the HB digital S099 water/oil heating bath, which heats up to 180 degrees Celsius and shows the temperature digitally. The package is completed by uncoated vertical glassware and a Woulff safety bottle, which protects against suck-back into the vacuum system. The RV 8 V thus covers the gap between the compact RV 3 entry-level package and the fully automated RV 10 packages, for laboratories that need higher temperatures but still want to work manually.
Selection guide: RV 3, RV 8 or RV 10, and which specification level?
The RV 8 series differs from the RV 3 series mainly in the heating bath: instead of a pure water bath up to 99 degrees Celsius, the RV 8 V uses a water/oil heating bath with digital temperature display and a heating temperature range up to 180 degrees Celsius, plus a wider speed range from 5 instead of 20 rpm. The following overview classifies the five common complete packages of the RV series.
| Model designation | IKA RV 3 V | RV 3 V-C | RV 8 V | RV 10 digital V Starter Solution | RV 10 auto pro V-C |
| Lift | manual | manual | manual (hand lift) | motor with safety stop | motor with safety stop |
| Control level | eco | eco | heating bath with digital display | digital | auto, with integrated vacuum controller |

Differentiation within the RV family
Anyone who works with low-boiling, aqueous solvents and does not need a heating bath temperature of 180 degrees Celsius is often well enough and more cheaply equipped with the smaller IKA RV 3 V rotary evaporator Anyone who prefers coated glass for additional splinter protection will find, in the IKA RV 8 V-C rotary evaporator the same drive and heating bath combination with coated instead of uncoated glassware. For laboratories that also want an integrated vacuum pump in the set, the Pro version IKA RV 8 pro V-C Complete rotary evaporator is the next step up. Since the RV 8 V includes neither a vacuum pump nor a recirculating chiller, we recommend the IKA RC 2 lite recirculating chiller, which according to the manufacturer is expressly intended for cooling rotary evaporators. Within the RV 8 family itself, the specification can thus be adapted step by step without having to switch to a different size.
Typical applications
The RV 8 V rotary evaporator is suitable wherever higher heating bath temperatures up to 180 degrees Celsius are needed:
- Distillation and concentration of higher-boiling solvents in an oil bath
- Routine operation in chemistry and QA laboratories with changing temperature requirements between aqueous and oil-bath-suitable batches
- Natural product chemistry and extract concentration, where a wider speed range is helpful for different viscosities
- Applications with a suck-back risk, where the supplied Woulff bottle serves as an additional safety stage
- Chemistry, pharmaceuticals, bioindustry, research and development, production and quality assurance, and plant engineering as the fields of application named by the manufacturer
Manual vacuum control at higher process temperatures
Since the RV 8 V works without an integrated vacuum controller, pressure control lies with the separately procured vacuum pump or an upstream vacuum controller. In oil bath operation near the upper temperature limit of 180 degrees Celsius, the vapour pressure of many solvents rises considerably faster than in the aqueous low-temperature range, which is why applying the vacuum slowly and step by step is particularly worthwhile to avoid bumping and foaming. The supplied RV 3.4 Woulff bottle serves here as an additional safety stage: should a back-up nevertheless occur, it catches condensate before it reaches the vacuum line or the pump. The hand lift with 120 millimetres of stroke also allows the flask to be raised quickly out of the hot oil bath if the process has to be interrupted at short notice.
Use, installation and maintenance
The drive unit is designed for ambient temperatures of 5 to 40 degrees Celsius and a relative humidity of up to 80 per cent, protection class IP 20 according to DIN EN 60529. When operating the HB digital oil heating bath near the upper temperature limit of 180 degrees Celsius, attention must be paid to a sufficient oil level and intact carrying handles, since the bath becomes correspondingly hot at these temperatures. The RV 3.4 Woulff bottle should be emptied regularly and checked for tightness so that it reliably protects against suck-back of condensate into the vacuum line in an emergency. The RV 10.8001 seal on the vapour duct is a wearing part and should be the first thing to check if vacuum tightness declines. The drive unit is operated at 100 to 240 volts at 50 or 60 hertz and draws up to 1500 watts, slightly more than with the RV 3 V, which should be taken into account when fusing the laboratory connection. After the oil heating bath has cooled down, it should additionally be ensured before relocating or transporting it that no residual oil can escape, especially if the carrying handles are used for transport, since these rest directly against the hot heating bath and can retain residual heat for longer.

Regulatory information
As an electrical device, the RV 8 V falls within the scope of the WEEE Directive (ElektroG) and bears the IKA registration number DE 66784213. After the end of its service life, the statutory take-back obligation applies, and disposal with household waste is not permitted.
Investment logic: what is in the set, what is still missing?
The drive, heating bath, glassware and suck-back protection are already covered by the RV 8 V, but for operation under vacuum a vacuum pump of its own is missing, and for a closed cooling circuit a recirculating chiller such as the IKA RC 2 lite. Anyone who additionally wants coated glass or an integrated vacuum pump will find this specification in the RV 8 V-C or in the Pro version RV 8 pro V-C Complete, without the drive and heating bath base having to change. For laboratories with occasional need for higher temperatures, the RV 8 V is therefore the obvious addition to an existing RV 3 device, rather than replacing it completely. Since the RV 3 and RV 8 both lack a vacuum pump and recirculating chiller in the same way, both devices can ideally be operated via a shared, already existing vacuum and cooling water infrastructure, which considerably reduces the investment in a second, larger device.
Frequently asked questions
- How hot does the heating bath get? The HB digital water/oil heating bath heats from room temperature up to 180 degrees Celsius, considerably more than the pure water bath of the RV 3 series.
- Is a vacuum pump included in the scope of delivery? No, the package contains the drive, heating bath, glassware and a Woulff safety bottle. A vacuum pump has to be procured separately.
- What is the Woulff bottle for? As a safety bottle, it protects against condensate being sucked back into the vacuum line or the pump in the event of a pressure surge.
- Is the glassware coated? No, the RV 8 V includes the uncoated RV 10.1 glassware. The coated version is available as the RV 8 V-C.
- How is the lift operated? The hand lift is manual, with a stroke of 120 mm.
- Which recirculating chiller suits this device? The manufacturer expressly names the cooling of rotary evaporators as a field of application for the IKA RC 2 lite.
- What power consumption does the drive unit have? Up to 1500 watts at 100 to 240 volts and 50 or 60 hertz, slightly more than the RV 3 versions with 1400 watts.
- Can I also operate the oil heating bath with water only? For water operation up to 99 degrees Celsius, the RV 3 V or RV 3 V-C is designed by construction. The HB digital of the RV 8 V is specifically designed for the extended temperature range up to 180 degrees Celsius with oil.
