Vacubrand are proud to introduce two new diaphragm pumps, the ME 1 and ME 1 C for filtration and sample preparation in chemistry, microbiology, waste water control and other analytical applications. These two pumps are compact, offer high performance and are easy to use. They are ideal for both single and multiple filtrations.

The ME 1 is suitable for aqueous filtration and the ME 1C with its exceptional chemical resistance properties is ideal for more aggressive solvents.

With a new top mounted power switch and space saving design, the ME 1 and ME 1 C are easy to use (even with gloves) and require minimal bench space. An optional manual control valve is available with a dial gauge to enable variable fine adjustment of the pumping speed (max. 0.7 m³/h).

Based on the MD 1 and MD 1C series, the ME 1 and ME 1C provide a well-proven and long diaphragm life time.

The Vacuubrand Chemistry-HYBRID-pump RC 6 provides the vacuum performance of an oil-sealed two-stage rotary vane pump (10^-3 mbar) with the unique ability to safely pump condensable or aggressive gases.

The RC 6 is ideal for benchtop freeze dryers, centrifugal evaporators, high-boiling point solvent evaporation and fine vacuum distillation.

Common rotary vane pumps’ corrosion weaknesses are overcome using a chemistry inert diaphragm backing pump. This pump evacuates the oil stages of the rotary vane pump and reduces both the oxygen partial pressure and the partial pressure of corrosive gases. Any reactions within the oil and potential corrosion attacks on the pumping unit are therefore significantly reduced. To ensure the dew point of most common solvents is never reached, the RC 6 balances the pressure and temperature within the oil reservoir. This drastically reduces the occurrence of condensation within the oil stages and increases the oil’s lifetime by many hundreds of percent.

The RC 6 can operate in a variety of applications without the need for a cold trap. Other noteworthy advantages include its drastic reduction of waste oil, its unique ability to condense and recover hazardous vapours, and its resistance to corrosive vapours.

The new chemistry HYBRID pump RC 6 is a great solution for all applications where less than 2 mbar vacuum and corrosion resistance is essential.

The new Vacuubrand automatic chemistry vacuum pumping system PC 3001 VARIO offers latest chemistry diaphragm pump technology combined with a unique fully automated vacuum control system. Applications include rotary evaporation, vacuum concentration, vacuum drying, general distillations and even filtration.

PC 3001 VARIO is an oil free, corrosion resistant pumping system with "high" vacuum. The outstanding ultimate vacuum of 2 mbar allows use with high boiling point solvents like DMSO or DMF at temperatures as low as room temperature.

The vacuum controller’s unique software automatically detects the required process vacuum and tracks changes in the system. Common problems in distillations like bumping of solvents are prevented which lets you concentrate on real research work rather than babysitting your vacuum application.

Vacubrand’s unique encapsulated cylinder head design with stability cores prevents 3 dimensional plastic creeping – outwards, inwards and downwards – which is a common reason for performance loss in other brands. Together with the non-contact flat sandwich diaphragm design this provides long term performance stability and reliability, but most importantly, it provides no stress on the motor. The result is low noise, low temperature and ultimately a much longer life expectancy. Vacuubrand wear part lifetime is up to 20,000h. A further advantage of the non-contact flat sandwich technology is higher performance under vacuum leading to shorter process times.

PC 3001 VARIO comes complete with solvent recovery options including water or dry ice condensers.

Most laboratory water jet vacuum pumps consume around 250L of water per hour when used for 5 hours per day - that’s 312,500L per year. Consider how many water jet pumps are in your laboratory and calculate how much water is being used.

Vacuubrand’s diaphragm pumps don’t consume water or oil and don’t generate waste.

Due to greater performance under vacuum, Vacuubrand diaphragm pumps can replace multiple water jet pumps when used with our VACUULAN local area vacuum system. Unlike most water jet pumps which send pumped media into the waste water system, diaphragm pumps can protect the environment and laboratory staff by using solvent recovery technology.

Diaphragm pumps are available with ultimate vacuum down to 0.3 mbar and 12 m³/h - in a chemistry or aluminium design for non-corrosive applications. All pumps feature temperature safety cut-out switches. Gas ballast comes standard with the Vacuubrand chemistry pumps to improve performance when pumping condensable vapours.

Vacuubrand’s non-contact flat diaphragm design and unique encapsulated cylinder head design with stability cores provides long term performance stability and reliability. Vacuubrand’s wear part lifetime is up to 20,000h for VARIO models.
