When you're piecing together a lab heating, cooling, and vacuum station, the pump often gets the least attention until it's time to pull a vacuum. Two very different options are competing for that spot. The Savant Instruments Laboratory Vacuum Gel Pump GP110-120 is listed at $149.00 and comes to you used. The Win Outdoor HZW-165 is listed at $80.99 as a new open-box item. One is a specialized pump; the other is a broader lab vacuum. Which should you buy depends on the job you need it to do.
Quick Verdict
Choose the Savant GP110-120 if your lab workflow is built around a dedicated gel pump and you're comfortable with a used unit. Choose the Win Outdoor HZW-165 if you want a general-purpose lab vacuum that arrives as a new open-box item and you don't mind adding the small setup pieces described in the listing.

Where Each Pump Wins
The Savant GP110-120 is the better fit when your work is tied to a gel-pump workflow. The unit was pulled from a working environment, so you're getting a pump with a documented history.
The Win Outdoor HZW-165 wins when you want a more general-purpose lab vacuum. It is listed as new open-box, and the setup path is simple: add a silencer and filter, then plug in. The package makes it a good candidate for a bench that needs flexibility.
Product Notes
Savant Instruments Laboratory Vacuum Gel Pump GP110-120
The Savant GP110-120 is a used gel pump with a working-environment history. The listing describes typical signs of wear like scratches and scuffs, and says it was tested to power on only. That means you're getting a power-on-checked unit, but you are not getting a load-tested one. The Gel pump classification is the real reason to consider it: this is not a general-purpose lab vacuum but a piece of equipment aimed at gel work. For a lab that already runs gel procedures and needs a dedicated pump, that specificity is useful. The limitation is the used condition, so you'll want to assess whether the wear matters for your workflow.
2- Stage 50L/m Oil Free Lab Vacuum Pump Oilless Medical Mute Pump HZW-165 (110V
The Win Outdoor HZW-165 is a new open-box oil-free lab vacuum pump built around a 2-stage, 50L/m design. The listing's setup path is straightforward: attach a silencer at the air outlet, add a filter at the air inlet, then plug in. That makes it a much more approachable option for a general lab bench, especially because the oil-free design removes oil changes from the routine. It's also listed as portable and weighs 8.82 pounds, with product dimensions of 10.63 x 9.84 x 7.09 inches if you're planning bench space. The main limitation is the open-box condition: even though it's described as new, you'll need to supply the silencer and filter the setup description mentions. For a flexible, low-maintenance lab vacuum, this pump is a strong choice.
Final Choice by Use Case
Choose the Savant GP110-120 if you need a dedicated gel pump and are willing to work with a used unit that was checked for power-on only.
Choose the Win Outdoor HZW-165 if you want a portable, low-maintenance lab vacuum for general bench use and you're comfortable with a new open-box item.
