Scharlau premium minireactors for liquid-phase synthesis
4 de November de 2023Precision and versatility are essential factors in scientific research and chemical synthesis. Scharlau supplies glassware minireactors specifically designed for liquid-phase synthesis, with outstanding technical features and flexibility that can be adapted to various applications. This blog post has a detailed look at these minireactors and how they can revolutionise your laboratory.
Both models are available from 50 mL up to 2000 mL. Their most outstanding characteristics, technical specifications and how they can be adapted to various applications are described below.
Premium model HME-R
- Temperature range: From room temperature +30°C to +250°C, in 0.5°C intervals.
- Stirrer speed range: Microprocessor controlled, with a range of 100–700 rpm, in 10 rpm intervals.
- Programmes: Capacity for up to ten 6-segment programmes, including temperature, speed, and time.
- Pressure range: From 5 mbar up to 0.7 bar of overpressure.
- Display: Colour touchscreen for easy monitoring.
- Materials: borosilicate 3.3. glassware, PTFE and Hastelloy® for excellent chemical resistance.
- Alarm: Equipped with an audible alarm.
- Over-temperature protection: Includes an automatic safety shutdown.
- Base dimensions: 276 x 315 mm.
- Power: 800 W hot plate and 50 W stirrer.
- Voltage: Operates on 220 V and a frequency of 50-60 Hz.
Premium model M-R
- Temperature range: Depends on the circulating bath to which it is connected.
- Stirrer speed range: Microprocessor controlled, with emphasis on the speed and timing. The temperature is recorded, but not controlled.
- Programmes: Capacity for up to ten 6-segment programmes for speed and time control.
- Pressure range: From 5 mbar up to 0.7 bar of overpressure.
- Display: Colour touchscreen to monitor the process.
- Materials: borosilicate 3.3. glassware, PTFE and Hastelloy® for maximum durability.
- Alarm: Equipped with an audible alarm.
- Over-temperature protection: Includes an automatic safety shutdown.
- Base dimensions: 276 x 315 mm.
- Power: 50 W stirrer.
- Voltage: Operates on 220 V and a frequency of 50-60 Hz.
Replacement parts
Minireactor maintenance requires just two replacement parts, namely two different O-rings.
- O-ring between the main vessel and the lid: 500-0MRJ25 (2.5” O-ring), 500-00MRJ3 (3” O-ring) and 500-00MRJ4 (4” O-ring).
- Stirrer shaft O-ring seal: OR6X178SIL (6.07 x 1.78 O-ring).
Installation and customisation
The minireactors are delivered fully assembled and ready for use. If any parts need adjusting, assembling or disassembling, there is a user’s manual video available on our website that provides detailed instructions.
There is also an option to customise the lid configuration to suit your specific needs.
Applications and flexibility
Scharlau minireactors are primarily designed for liquid-phase synthesis. However, with a few modifications, we can offer solutions for:
- API or solid-phase synthesis (e.g., peptide synthesis).
- Catalyst testing.
- Working at very low temperatures with a thermostated reactor and vacuum jacket.
- Working at moderate overpressures (up to 5 bar).
- Use as a fermenter.
- Customised photochemical reactors.
If the stirrer speed range needs to be adjusted for operation at less than 100 rpm, we can also provide a mechanical stirrer in that specific range.
Main features
These are just some of the notable advantages of our Scharlau minireactors:
- Mechanical stirring with simple alignment.
- Simple height adjustment of the stirring rodn.
- Telescopic stand.
- Clamp with quick opening and closing, no tools required.
- Silicone/FEP O-rings with a PTFE self-centring ring.
- Inert materials, including Hastelloy® stirring rod.
- Reaction vessels available from 50 mL to 2000 mL.
- Aluminium heating block for fast, homogeneous heating (model HME-R).
- Reduced base dimensions.
Scharlau minireactors are the ideal solution for laboratories looking for accuracy, versatility and durability. Both models can be adapted to your needs, and we offer custom-made solutions for your research and chemical synthesis.
