Aspirator Q-1

Code No.: 0000336-000

Circulates water in the water bath and exerts suction with the water flow. The suction depends on the water temp. The water circulates in the tank makes no concern for discharge of contaminated water.

Combined with Test tube Concentrator TC-8F


Aspiration of Waste liquid in experimental operation
Depressurization of Test tube Concentrator TC-8F and suction filtration

Down Load(Useful Information)

General Catalog


Equipped with Two Suction ports
The Pressure reducing Valve (sold separately) can be attached to either ports. The suction (vacuum degree) can be stabilized by using the Pressure reducing Valve while keeping the water temp. constant. See below for stabilization on water temp.
Water temperature and Suction (vacuum degree) in relation.
As the vacuum degree that is obtained from the Venturi effect varies depending on the water vapor pressure, the water temp. is related to the suction. It is easier to maintain suction (vacuum degree) and improve reproducibility by throwing Ice or the Cooling pipe into the tank or cooling the water inside bath with the Circulator for Open circuit (See right table). Also, when the Cooling pipe or Circulator is used, the samples that are limited to those materials are not damaged.
”Aspirator” generates suction by water flow

The simpler device than Vacuum pump to get suction effect by Venturi effect by water flow. As it causes the water flow by circulating the water in the bath, it is suitable for long-time use compared to the method of connecting to the tap water supply. No concern for discharge of contaminated water.
*The disposal of water in the water bath.
Aspirator mixes the aspirated waste fluid and the evaporated solvent into the water stream in principle. Dispose the water in the tank after drying the organic solvent, etc. under the reduced pressure or suck up the waste liquid according to regulations (Be careful in particular with the Low boiling point solvents that can easily be liquefied and mixed at once).
