Application
Vacuum pumps for laboratory vacuum and glove boxes
In the laboratory, vacuum works on many instruments: on the rotary evaporator, the desiccator, filtration, the freeze dryer, the mass spectrometer and the glove box, in which air-sensitive substances stay under protective gas. For this Pfeiffer Vacuum describes quiet, clean vacuum for mass spectrometry, freeze drying, glove boxes and filtration, supplied individually at the instrument or centrally. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it ā 131 models from 6 manufacturers.

In short
Laboratory vacuum and glove boxes: the key facts
- QuietFor the HiScroll Pfeiffer Vacuum names about 45 dB ā quiet, clean vacuum for mass spectrometry, freeze drying, glove boxes and filtration.
- Glove boxFor glove boxes Edwards describes: remove the residual air, then fill with nitrogen or argon; Pfeiffer Vacuum names clean vacuum for air-sensitive work (HiScroll), Becker gas circulation in glove boxes.
- Chemistry laboratoryFor chemistry, pharmacy and chemistry laboratories Leybold lists TRIVAC B (BCS PFPE), NEO D and SCROLLVAC; Atlas Copco names DVS and GVS A for general and chemical laboratories.
- UniversitiesEdwards names RV and E2M for laboratories and universities in chemistry, biology, physics and geology.
Operating principle
How it works: Laboratory vacuum and glove boxes
The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.
- EvacuationThe pump draws the air out of the instrument or glove box; for glove boxes Edwards describes the removal of the residual air.
- WorkingUnder vacuum, samples are evaporated, filtered, dried or measured ā Pfeiffer Vacuum names mass spectrometry, freeze drying, glove boxes and filtration.
- VentingThe instrument is vented; according to Edwards, the glove box is filled with nitrogen or argon so that the sample does not come into contact with air.
Vacuum and sizing
Laboratory vacuum and glove boxes: how much vacuum is needed
What the manufacturers say about pressure, pumping speed and sizing.
Which vacuum
The pressure required depends on the instrument and the solvent; as a figure Pfeiffer Vacuum names the noise: HiScroll about 45 dB.
Which pumping speed
Pfeiffer Vacuum distinguishes between supply individually at the instrument and central supply; Atlas Copco names GVS A for the central laboratory.
What determines the design
Cleanliness and noise (Pfeiffer Vacuum), compatibility with chemicals ā for chemistry laboratories Leybold lists TRIVAC B in the BCS PFPE version ā and, for the glove box, the protective gas (Edwards: nitrogen or argon).
What the manufacturers point out
Besides laboratory vacuum, Becker names gas circulation in glove boxes; Busch names COBRA for glove boxes and isolators; Edwards names rotary vane and scroll pumps for glove boxes.

Frequently asked questions
Laboratory vacuum and glove boxes: frequently asked questions
Which vacuum pump for the laboratory?
For laboratory vacuum Pfeiffer Vacuum names HiScroll, ACP, DuoVane and SmartVane ā quiet and clean for mass spectrometry, freeze drying, glove boxes and filtration. Leybold lists TRIVAC B, NEO D and SCROLLVAC for chemistry laboratories, Edwards RV and E2M for laboratories and universities, Atlas Copco DVS and GVS A for general and chemical laboratories, Busch COBRA for glove boxes, Becker BCV.
Which vacuum pump for a glove box?
Pfeiffer Vacuum names the HiScroll for clean vacuum in air-sensitive work. Edwards names rotary vane and scroll pumps for glove boxes, Leybold the NEO D, Busch COBRA for glove boxes and isolators. Becker names gas circulation in glove boxes.
How does a glove box work with vacuum?
According to Edwards, the residual air is removed from the box and the box is then filled with nitrogen or argon; this keeps air-sensitive substances from coming into contact with oxygen or moisture. The vacuum pump evacuates the box or its airlock; Pfeiffer Vacuum names clean vacuum for this.
Oil-free or oil-lubricated in the laboratory?
Both are named. Pfeiffer Vacuum places the dry HiScroll at about 45 dB alongside the oil-lubricated DuoVane and SmartVane and the multi-stage ACP; Leybold lists the oil-lubricated TRIVAC B and NEO D alongside the dry SCROLLVAC; Edwards names rotary vane and scroll pumps for glove boxes; Atlas Copco the dry DVS and the oil-lubricated GVS A.
How loud is a laboratory vacuum pump?
For the HiScroll Pfeiffer Vacuum states about 45 dB and describes quiet vacuum as a requirement in the laboratory.
Which vacuum pump for the chemistry laboratory?
For chemistry, pharmacy and chemistry laboratories Leybold lists TRIVAC B in the BCS PFPE version, NEO D and SCROLLVAC. Atlas Copco names DVS and GVS A for general and chemical laboratories, Pfeiffer Vacuum ACP, DuoVane, HiScroll and SmartVane also for chemistry.
How much vacuum does a rotary evaporator need?
In physical terms: the lower the pressure, the lower the boiling temperature of the solvent; the pressure required therefore depends on the solvent and the bath temperature.
Which vacuum pump for universities and research laboratories?
Edwards names RV and E2M for laboratories and universities in chemistry, biology, physics and geology. Pfeiffer Vacuum names HiScroll, ACP, DuoVane and SmartVane, Busch COBRA for glove boxes and isolators in the laboratory.
Which vacuum pump for freeze drying and mass spectrometers in the laboratory?
Pfeiffer Vacuum names both under laboratory vacuum and, for them, HiScroll, ACP, DuoVane and SmartVane ā quiet and clean, individually at the instrument or central.
A single pump or a central vacuum system?
A central system in a room of its own keeps noise and heat away from production and matches its output to the demand. Central vacuum systems are planned and built by Eugen Theis Vakuum, a company of the Ehrler & Beck group ā more under Central Vacuum.
Does Ehrler & Beck also supply spare parts and service?
Yes. Ehrler & Beck offers original spare parts and accessories as well as maintenance and repair.
