Comments about Cole-Parmer Aspirator Pump, 18 L/min, 9.5l Bath, 115 VAC:
Catalog rates vacuum at 10 torr. This is possible only if water bath is less than 10 degress C. Aspirator OEM apparently makes a purpose-built cooler which is not stocked by Cole Parmer. Suggested Cole Parmer coolers cost way more than aspirator and are not portable. Addition of ice does permit obtaining 10 torr. We use for vacuum deaerating water. High moisture was damaging normal mechanical vacuum pumps. This device is immune to high moisture problem.
