Welch 8890A-70 Rotovap Pump
*****ALERT*****
Manufacturer Welch Vacuum has replaced this product line with the Welch CRVpro series. This pump is no longer in production.
The Welch CRVpro series is the latest innovation in the high vacuum, direct-driven vacuum space. Vacuum users can expect increased reliability and longer service live when compared to other direct drive, rotary vane vacuum pumps.
- Consumes up to 36% less oil than comparable pumps
- Runs 10°C cooler than comparable pumps. This reduced the degradation of vacuum pump oil, increasing the running time between service intervals.
- Has a 40% larger oil capacity than comparable pumps. Dilutes aggressive chemicals.
- Has a chemical resistant coating in the oil case and pump module. Protects non-moving parts.
-------------------------------------------------------------------------------------------------------------------
- Evaporates high boiling solvents
- Handy vacuum level measurement and adjustment
- Exhaust oil recycler eliminates oil mist
Rugged GEM direct drive gear pumps provide versatile vacuum for applications requiring a broad range of vacuum level operating conditions. GEM pumps can operate continuously in the pressure range that rotary vane pumps can not: 10 torr up to atmospheric pressure; oil recycler 1416B is recommended for prolonged operation over 1 torr. Maximum vacuum = 0.1 torr (0.133 mbar). Includes exhaust oil recycler 1416B, vacuum gauge and regulator.
