Safety
The user, product, process and instrument was always the focus at BUCHI. The R-220 SE is now lifted up to a new safety level.
User protection
Protection of the operator is of high value with all BUCHI instrumentation. With the focus on easy handling, the risk of maloperation is reduced and the unit gets more safe. This also means that even the simplest and most economical Rotavapor offers maximum protection, without having to purchase additional safety equipment.
“Plastic+Glas” coating on all glass components with the exception of evaporating flask. This coating offers maximum protection for personnel against implosions and glass breakage without hindering operation.
Spring-loaded shut-off valves prevent glass breakage as a result of excessive force during closing.
EasyClamp connections for quick and safe assembly of glass joints.
Patented evaporation flask clamp allows safe single user operation.
Product assurance
Maximum protection for thermo sensitive products against excessively high temperatures.
- An adjustable upper temperature limit prevents unintentionally change of the set point
- An over temperature sensor switches the Rotavapor off when set point temperature has been exceeded by 15 °C
- A mechanical over temperature protection feature protects the heater from burning out
In the event of a problem, the bath is lowered automatically, the heater switches off and the rotation stops.
This optional level sensor stops the R-220 SE when the solvent level in the receiving flask is achieved. Particularly helpful for concentration of product. The same sensor can also be used to detect the solvent in the secondary condenser of the Vacuum pump V-710 to prevent an overflow.
Instrument protection
Additional protection of the instruments is often required in production facilities. For this reason a safety shield made of PMMA is available for the R-220 SE; this shield protects the entire glass assembly.
Unrestricted visibility of the process
Front access to all valves and controls via doors
The coated glass components ensure the protection of the user even with the doors open
The pivoting polycarbonate bath shield protects, on the one hand, the evaporating flask and, on the other hand, the user against splashing.
Transparent shield for continuous visibility of the product throughout the entire evaporation process.
Pneumatic spring for easy pivoting and retention of the shield.
Safety feature – rotation stops when shield is open.
Optional stainless steel cover protects the evaporation flask from above
A steel tube frame is also available as an accessory that provides additional side protection for the R-220 SE.
