Flex-MVP automated vacuum parallel concentrator

Organic Sample Preparation · 3 models

Vacuum parallel concentration removes solvent from many vessels at once under reduced pressure, heating and vortex oscillation, and recovers the solvent instead of venting it. LabTech's MVP series is built for that batch: Flex-MVP runs 16 channels with 200 mL or 50 mL cups, MVP 12 handles 900 mL cups and large-volume work, and MVP 48 takes 48 positions in 60 mL bottles or 50 mL centrifuge tubes. All three share one design principle, with each vessel sealed and exhausted on its own line.

Add or remove mid-run

Vessels are sealed individually, so one sample can be loaded or taken out without stopping the others.

No cross contamination

Each cup exhausts through its own line, containing bumping and boil-over to a single vessel.

Solvent recovery

Solvent is recovered rather than vented; MVP 12 recovers 85 percent or more of a 500 mL petroleum ether load.

Full-surround heating

The water bath surrounds each cup, transferring heat into the vessel wall and shortening the evaporation step.

Models

Choose the configuration.

Independent sealing matters because a single bumping sample can otherwise cross-contaminate a whole batch. On these systems each concentration cup has its own line, so a sample can be added or removed without depressurizing the chamber or pausing the other vessels. Full-surround water-bath heating wraps the cup rather than heating it from one side, and the transparent chamber and flip-up lid keep the batch visible and accessible.

Flex-MVP

16-channel automated vacuum parallel concentrator

Flex-MVP is a 16-channel vacuum parallel concentrator that accepts 200 mL or 50 mL cups. Its sample rack and cover form one flip-up lid with snap locks, and the concentration chamber is fully transparent. Vessels can be sealed individually as well as collectively, so a single sample can be added or removed without pausing the instrument or releasing vacuum on the rest of the batch.

16 channels with 200 mL or 50 mL concentration cups.
Individual or whole-batch sealing, with no need to pause or depressurize.
Flip-up lid with snap locks opens and closes in one movement.
Each cup has its own sealed line and independent exhaust path.
Full-surround water-bath heating around every cup.
Adaptive sealing accommodates dimensional variation in glassware.
Fully transparent chamber keeps the whole batch visible.

Channels	16 simultaneous
Cups	200 mL or 50 mL
Sealing	Individual and whole-batch, adaptive to glassware tolerance
Heating	Full-surround water bath
Chamber	Fully transparent

MVP 12

12-channel large-volume vacuum parallel concentrator

MVP 12 concentrates 12 samples at once in 900 mL cups and supports large-volume work up to 1000 mL. Under heating, reduced pressure and vortex oscillation it evaporates samples to dryness or to a set volume and recovers the solvent, with 500 mL of petroleum ether recovered at 85 percent or more. It is used for oil enrichment ahead of acid value and peroxide value testing in food.

12 channels concentrate simultaneously in 900 mL cups.
Supports large-volume concentration up to 1000 mL.
500 mL petroleum ether recovery of 85 percent or more.
Full-surround water-bath heating raises evaporation efficiency.
Safety lock allows instant lid opening and closing.
Independent lines per vessel prevent carry-over from bumping.
Suited to oil enrichment for acid value and peroxide value testing.

Channels	12 simultaneous
Cups	900 mL
Sample volume	Large-volume concentration up to 1000 mL
Solvent recovery	500 mL petroleum ether, 85 percent or more
Lid	Safety lock, instant open and close

MVP 48

48-position vacuum parallel concentrator

MVP 48 brings the same vacuum concentration principle to 48 positions, using 60 mL bottles or 50 mL centrifuge tubes. Sealing lids are elastic to take up container variation, and each vessel exhausts independently so bumping stays contained. It is aimed at food, traditional Chinese medicine, environmental and agricultural laboratories running long sample series.

Up to 48 samples concentrated in one batch.
Compatible with 60 mL bottles and 50 mL centrifuge tubes.
Elastic sealing lids accommodate container tolerance.
Safety lock for instant, low-effort lid operation.
Independent exhaust lines contain bumping and prevent cross contamination.
Heating, reduced pressure and vortex oscillation drive evaporation.

Positions	Up to 48
Vessels	60 mL bottles, 50 mL centrifuge tubes
Sealing	Elastic sealing lids
Lid	Safety lock, instant open and close

Questions

Before you buy.

How does vacuum parallel concentration differ from nitrogen blow-down?

Vacuum concentration lowers the boiling point under reduced pressure while heating and oscillating the vessel, and it recovers the evaporated solvent. Nitrogen blow-down directs a gas stream across the liquid surface instead. The two approaches suit different volume ranges and different needs for solvent recovery.

Which MVP model handles the largest volume?

MVP 12 supports large-volume concentration up to 1000 mL in 900 mL cups across 12 channels. Flex-MVP takes 200 mL or 50 mL cups in 16 channels, and MVP 48 takes 60 mL bottles or 50 mL centrifuge tubes across 48 positions.

Can samples be added or removed during a vacuum run?

On Flex-MVP, yes. The combined whole-batch and individual sealing design lets a single cup be added or removed without pausing the instrument or releasing vacuum on the other samples. Each cup has its own sealed line and exhaust path, so the rest of the batch continues unaffected.
