HFS Vacuum Pump vs Uimoso 6L Chiller: Pick the Right Lab Tool for Your Work

Choosing between a used vacuum pump and a new recirculating chiller comes down to whether your lab needs suction or precise temperature control. This head-to-head compares price, capabilities, and best use cases.

Last updated Aug 15, 2026

When you're equipping a lab, it's easy to get pulled in different directions. In the lab heating, cooling, and vacuum equipment space, two common tools solve very different problems: a vacuum pump that removes air and a recirculating chiller that manages fluid temperature. If you have room for only one right now, the choice comes down to the work in front of you. The HFS 2-Stage 12CFM 1HP Laboratory Vacuum Pump VP 2200 and the Uimoso 6L Laboratory Recirculating Chiller are priced far apart and built for different tasks. This head-to-head helps you match the equipment to your bench.

Quick verdict

If your immediate task is suction-dependent-vacuum filtration, degassing, or pulling lines-the HFS 2-Stage Vacuum Pump VP 2200 is the direct answer at USD 199.00. If your work needs a stable temperature from 23°F to 212°F, the Uimoso Recirculating Chiller at USD 668.99 is the better fit.

Where each product wins

  • HFS 2-Stage Vacuum Pump VP 2200 wins for vacuum work. It combines a 2-stage design with a 1 HP motor and is marked portable.
  • Uimoso Recirculating Chiller wins for temperature-sensitive protocols. Its dual circulation system can cool and heat, with a 304 stainless steel water tank and precise temperature display.

Product notes

HFS 2-Stage 12CFM 1HP Laboratory Vacuum Pump VP 2200

Workflows that need consistent vacuum have a strong option in the HFS 2-Stage 12CFM 1HP Laboratory Vacuum Pump VP 2200. The 2-stage design and 12 CFM free air displacement give it useful suction for filtering, degassing, and running multiple lines. It is marked as portable, so moving it between benches is practical. The pump works with standard 110-127V and includes a power cord, which keeps setup simple. The trade-off is condition: this is a used unit, and while it has been checked for power and basic function, it was not tested in the field of use. That makes it a reasonable pick when you can inspect the unit and confirm it suits your lab's workflow, but less ideal if you need a factory-fresh pump with no previous operating history.

Uimoso 6L Laboratory Recirculating Chiller

When temperature stability is the priority, the Uimoso 6L Laboratory Recirculating Chiller covers both cooling and heating tasks. Its range starts at 23°F and reaches 212°F, so the same unit can preserve biological samples or support chemical synthesis. The dual circulation system keeps the internal tank steady while also connecting to external equipment, giving it flexibility for small-scale experiments and larger processes. The 304 stainless steel water tank and temperature display with ±0.01°C resolution point to precise control. The main drawback is the footprint: at 54.5 lbs and dimensions of 12.6 x 15.6 x 26.2 inches, it is a stationary piece of equipment. Plan for dedicated bench space rather than frequent moves. If your work needs both heating and cooling in one instrument, the Uimoso is the more complete package.

Final choice by use case

Choose the HFS 2-Stage Vacuum Pump VP 2200 when the task is suction-focused: vacuum filtration, degassing, or running a manifold. It costs less and can be moved around, but it is a practical tool for vacuum work.

Choose the Uimoso 6L Recirculating Chiller when the task is temperature-focused: maintaining biological samples, driving chemical synthesis, or circulating heated or cooled fluid to external instruments. It is new, heavier, and built to stay in one place, and it covers a wide thermal spectrum.
