RVT450 mechanically refrigerated vapor trap for SpeedVac

The RVT450 is a mechanically refrigerated vapor trap from Thermo Scientific that condenses and collects solvent vapors during vacuum concentration with a SpeedVac. Firstly, the stainless steel chamber cools to approximately -50°C, which efficiently traps a wide variety of solvent vapors. Secondly, the RVT450 protects your oil pump from vapor contamination that degrades pump oil and shortens its lifespan. Moreover, this mechanically refrigerated vapor trap replaces traditional dry ice and methanol cold traps, which makes the working day significantly safer, cleaner and more cost-effective.

CFC-free and consumable-free

Firstly, the RVT450 features a sealed CFC-free refrigeration system. In addition, the unit eliminates the need for dry ice or acetone, which saves you significant costs on consumables each year. Furthermore, the included glass condensation flask (GCF400, 4L) safely collects solvents for disposal in accordance with environmental regulations. As a result, the unit operates continuously and can be left running for extended periods, provided the glass flask is regularly emptied.

Simple operation and maintenance

Firstly, you fill the stainless steel chamber once with 750 ml of CryoCool heat transfer fluid (SCC1 or SCC5, ordered separately). Secondly, you switch the unit on with the front panel switch, and the trap reaches its operating temperature in approximately 30 minutes. In addition, you swap the glass flask in just a few minutes without shutting down the RVT450. Furthermore, the unit requires minimal maintenance, with only periodic checks of hoses, seals and CryoCool level.

Combining with SpeedVac concentrators

Firstly, the RVT450 is designed as the cold trap in a modular SpeedVac setup. Secondly, the unit is the standard cold trap in our SpeedVac P1 kits, including the SRF110, SPD120 and SPD140DDA. Moreover, the RVT450 fits ideally on the lower shelf of a Convenience Cart (CC120/DX), with the SpeedVac concentrator on the upper shelf. As a result, choose the RVT5105 instead of the RVT450 when freeze drying or lyophilizing low-boiling solvents, because that unit cools to -105°C.
