Here at Molecularspray we design and manufacture compact portable ultra-high vacuum (UHV) electrospray deposition (ESD) systems to facilitate the deposition of complex, fragile and non-volatile molecules on surfaces under UHV conditions.
Our systems are helping research groups around the world in universities and industrial R&D to deposit dye molecules, nanorings, single molecule magnets, quantum dots, polymers, nanorods, proteins... find out more below.
The UHV4 is a modular electrospray deposition source capable of producing a molecular beam from an electrosprayed solution at pressures as low as the 10-8 mbar range. The system features a desolvation entrance capillary, two differentially pumped molecular beam skimmers and a final differentially pumped aperture [...]
The MV5+ and MV5- are designed with both portable and lab-based electrospray deposition in mind. Probably the smallest electrospray high voltage power supply available, it is housed in a robust aluminium case that can fit almost anywhere around even the most complex UHV system. The MV5 comes with [...]
The inlet heater quite simply heats the inlet capillary of the UHV4 electrospray deposition system. There is sometimes an advantage to heat the inlet in order to increase desolvation of the plume as it enters the vacuum stages. This self-contained heating unit is powered by its own 28V DC supply and is temperature regulated [...]
The visualizer add-on is a high quality 25X microscope and lightsource which is mounted to the front end of the UHV4 to enable the electrospray plume to be monitored during a deposition. It can be used manually with the eye-piece or through the HD video camera coupled to a computer [...]
Our systems are supplied as standard with the NewObjective stainless steel metal tapertips. We can also supply replacements and emitters of difference sizes. Simply email for a quote.
The SK4 service kit & spares set for the UHV4 system has been put together to help you deal with whatever your experiment throws at you. Things do go wrong. You could be in the middle of a key experiment at the synchrotron or on a short visit to another research lab when you break a syringe [...]
Stage 2 of the UHV4 series electrospray deposition system can be pumped using the backng pump of the turbo on stage 3 under most circumstances. The S23 coupler simply provides a way to connect the two pumping lines together so that only two scroll pumps and one turbo are required [...]
This redesigned CF 2.75" (DN35CF) entrance flange has the entrance capillary fitting machined directly into flange allowing the capillary to be tightly gripped accurately and reproducibly centred at the point where it enters the first skimmer stage. This new model also features a recessed thread [...]
This 10 ml gas-tight syringe is modified with PEEK fittings for a leak-free connection to the 1.6 mm (1/16") polymer capillary tubing to that delivers your solution to the electrospray head [...]
