Vacuum Pumps, Air Compressors and Lab Utility Equipment

The pumps, stirrers and enclosures that keep sample preparation running quietly.

VP30 anti-corrosion diaphragm vacuum pump

Laboratory Equipment · 6 models

Behind every filtration, evaporation and digestion sits a utility that has to keep working: a vacuum source, a clean air supply, a stirrer that does not lose the bar. LabTech builds that layer as separate, serviceable units, including a chemically resistant diaphragm pump, a filtration pump with adjustable vacuum, an air compressor with a stainless steel tank, a magnetic hotplate stirrer and an acoustic enclosure that takes pump noise off the bench.

Fluoroplastic wetted parts

Parts in contact with pumped gas are chemically resistant fluoroplastic, including the PTFE laminated diaphragm.

Oil-free operation

Diaphragm pumping removes the oil changes and maintenance that oil-sealed pumps demand.

Quiet by design

A wave-shaped acoustic enclosure with optimized airflow lowers pump noise without trapping heat.

Stirring that recovers

The stirrer detects a lost stir bar and recaptures it rather than stalling an unattended run.

Models

Choose the configuration.

The design brief across the family is corrosion resistance and low noise. Pump parts that touch gas are fluoroplastic, including a PTFE laminated diaphragm. The compressor dries its own air and drains itself. The stirrer detects a lost stir bar and recaptures it, and stops heating if the independent safety circuit trips. The enclosure wraps a noisy pump in wave-shaped acoustic foam while keeping airflow and temperature visible.

VP series diaphragm pump

Chemically resistant diaphragm vacuum pump

A two-stage, oil-free diaphragm pump range for rotary evaporation, filtration and vacuum concentration. Pumping speed runs from 18 to 50 L/min, ultimate vacuum from 20 to 250 mbar, and the wetted path is fluoroplastic with a PTFE-laminated diaphragm.

  • 18–50 L/min pumping speed
  • 20–250 mbar ultimate vacuum
  • Oil-free two-stage diaphragm
  • Fluoroplastic wetted parts

Magnetic hotplate stirrer

Magnetic hotplate stirrer with independent safety circuit

A hotplate stirrer for general bench work, built for high temperature and corrosion resistance. Temperature is set and shown on an LCD, and an external sensor can report the actual sample temperature rather than the plate temperature. If the bar decouples, the unit finds and recaptures it; if the independent safety circuit trips, heating stops.

  • High-temperature and corrosion-resistant construction
  • Precise temperature control with LCD digital display
  • External temperature sensor option for actual sample temperature
  • Detects a lost stir bar and recaptures it automatically
  • High explosion-proof safety rating
  • Independent safety circuit stops heating above the safety temperature

Air compressor

Laboratory air compressor with stainless steel tank

A clean, dry air supply for instruments and sample-preparation accessories. The compressor drains itself and passes air through a built-in centrifugal drying system and an electronic water remover. A large stainless steel tank keeps pressure steady, and a box-type enclosure with wave-shaped acoustic foam keeps the unit quiet enough to sit in the laboratory.

  • Automatic drainage with built-in centrifugal drying for clean, dry air
  • Large-capacity stainless steel air tank for stable pressure
  • Electronic water remover for thorough moisture removal
  • Compact, lightweight and rust-resistant unit
  • Complete compressor protection system
  • Enclosed cabinet with wave-shaped acoustic foam for low noise
  • Simple to operate and maintain

Sound enclosure

Acoustic enclosure for vacuum pumps

A cabinet that puts a quiet shell around a noisy pump. Wave-shaped foam with fine pores absorbs sound as air passes through, and the inlet and outlet are shaped to keep air moving through the box. Temperature is monitored and shown on an LED display, and casters let the whole assembly be rolled aside for maintenance.

  • Wave-shaped acoustic foam absorbs sound across the cabinet
  • Optimized inlet and outlet airflow for heat removal
  • Real-time temperature monitoring with LED display
  • Assembles easily from illustrated instructions
  • Casters for moving the pump and servicing it

Light-wave heating instrument

Near-infrared light-wave heating instrument

A heating instrument that works by radiation rather than through a hot plate surface. Near-infrared light heats the sample directly, with conduction as a secondary path, so temperature comes up quickly and evenly across the vessel. Power and temperature are both adjustable, and a timer lets the instrument run a set program.

  • Near-infrared heating: radiation first, conduction second, for a fast ramp
  • Even light distribution across every part of the sample
  • Low power, fast heating
  • Special surface treatment for corrosion resistance
  • Adjustable heating power and temperature
  • Timer-controlled operation

Vacuum filtration pump

Filtration vacuum pump with adjustable vacuum

A filtration pump for large volumes and difficult liquids. High displacement gives it an advantage with heavy filter loads, viscous media and particle-rich samples, and a pointer gauge shows system vacuum while a knob sets it. The PTFE vacuum diaphragm is molded in one piece, with extra thickness for fatigue resistance.

  • High displacement for large filtration volumes
  • Suits high-viscosity and particle-rich media
  • Pointer gauge shows system vacuum in real time
  • Pressure knob adjusts vacuum to the method
  • One-piece PTFE vacuum diaphragm, thick-walled and fatigue resistant
  • Compact housing with low noise and low vibration
  • Several vacuum levels available

Questions

Before you buy.

Which vacuum pump suits corrosive solvent vapors?

The anti-corrosion diaphragm vacuum pump is the model for solvent vapor: every part that can contact the pumped gas is fluoroplastic, the diaphragm is PTFE laminated, and the two-stage design reaches a low ultimate vacuum without oil. For filtration work with large volumes, viscous liquids or particle-rich samples, the vacuum filtration pump adds high displacement and a vacuum knob with a pointer gauge.

How do I reduce vacuum pump noise in the laboratory?

Use the sound enclosure. Its wave-shaped, finely porous foam absorbs sound as air passes through, while the optimized inlet and outlet keep air moving so the pump does not overheat. Temperature is monitored and shown on an LED display. It assembles from illustrated instructions and sits on casters, so the pump can be moved for maintenance without dismantling anything.

Why does a magnetic stirrer need an external temperature sensor?

The plate and the sample are not at the same temperature. The magnetic hotplate stirrer supports an external sensor so the reading reflects the sample itself, and its LCD shows the set value digitally. The unit also detects a stir bar that has decoupled and recaptures it, and an independent safety circuit stops heating if the safety temperature is exceeded.
