Vacuum filtration can support e-liquid and vape laboratory sample preparation by separating particulates from liquid samples before further testing, where required by the analytical method. A suitable vacuum system should provide sufficient pumping capacity, chemical resistance, and adjustable suction for the filtration setup.

• The ME 1C chemistry diaphragm pump reaches 100 mbar and 0.7 m³/h, making it the right size for filtering formulations, raw materials, or analytical samples during particulate removal and sample prep.
• Upgrade to the ME 2C NT Chemistry diaphragm pump (7 mbar, 2.1 m³/h) when your lab needs higher throughput on the same filtration and SPE workflows.
• Both pumps are oil-free and chemically resistant, which we recommend for filtration and SPE tasks involving flavor and nicotine-containing liquids.

Vacuum degassing removes dissolved gases and entrained air from liquids. In e-liquid and vape laboratories, it can support sample preparation or formulation development where bubbles interfere with a defined testing or processing method. The vacuum system should remove gas while limiting foaming and unintended loss of volatile ingredients.

• The MZ 1C and MZ 2C NT chemistry diaphragm pumps are built to remove entrained air and bubbles from PG/VG and flavor mixtures after blending, a step formulations need before they're stable enough to bottle.
• The MZ 1C reaches 12 mbar for standard batch sizes, while the MZ 2C NT adds pumping speed for larger or faster-moving degassing processes.
• The chemistry-resistant diaphragm design accounts for the flavor components and vapors that can be present during degassing.

Controlled vacuum enables solvent evaporation at lower temperatures. In vape laboratories, this can support sample concentration or solvent removal during analytical preparation and development, where specified by the method. Stable pressure helps maintain effective evaporation while limiting bumping and excessive thermal exposure.

• For R&D work involving volatile flavor components, solvent removal, concentration, or rotary evaporation, the PC 3001 VARIO select is one of BRANDTECH's strongest premium options for e-liquid applications.
• Chemical-resistant and oil-free, with automatic VARIO vacuum control for precision, we recommend this pump for the kind of precision rotary evaporation flavor R&D demands.

Vacuum aspiration transfers liquid from sample vessels into a collection bottle, supporting organized waste handling during laboratory work. In vape labs, potential applications include removing compatible aqueous wash solutions or residual liquids from testing vessels. The system should provide adjustable suction and contain the collected waste without allowing liquid to reach the pump.

• The BVC control fluid aspiration system integrates a chemistry diaphragm pump with a collection bottle and electronically adjustable suction, making it suitable for removing liquid waste, cleaning vessels, and handling QC and sample-prep liquids.
• The BVC professional fluid aspiration system adds a non-contact liquid-level sensor for additional protection against overfilling. 
• Collection options include 2 L borosilicate glass and 4 L polypropylene bottles.

• For e-liquid labs running filtration, aspiration, degassing, and other vacuum needs across several benches at once, a VACUU·LAN laboratory vacuum system which includes one or more VACUUBRAND chemistry diaphragm pumps to distribute vacuum lab-wide while keeping every connection oil-free and chemically resistant.
• BRANDTECH positions VACUU·LAN lab vacuum systems specifically for multi-user labs running chemical R&D and QC side by side.
