Precision Vacuum for Laboratory & R&D Applications

Patkar's lab vacuum range brings the same OTL™ engineering principles to smaller-scale laboratory and pilot plant applications, delivering clean, consistent, deep vacuum for research, development, and quality control.

Same OTL™ principles. Lab scale.

Most lab vacuum pumps are imported, expensive to service, and not designed for the vapor loads common in Indian pharmaceutical R&D. Patkar lab pumps are built in India with the same engineering philosophy as our industrial OTL™ range.

Clean vacuum output

No oil migration into your process stream, critical for analytical and pharmaceutical R&D work where contamination invalidates results.

Locally serviced

Spares available from Thane. No waiting on imports. Our engineers understand Indian lab environments, chemistries, and process conditions.

Consistent deep vacuum

Rotary vane design achieves and maintains deep vacuum throughout your experiment, no drift that would compromise analytical accuracy or process replication.

Two models for laboratory & pilot scale

Lab vacuum or industrial OTL™?

Choose Lab Vacuum if...

  • Your application is in a laboratory or R&D setting
  • You need bench-top or compact installation
  • You're running pilot trials before scaling to production
  • Your vapor load is low (single vessel or small setup)
  • You want to test OTL™ performance at smaller investment

Choose Industrial OTL™ if...

  • You're running production-scale distillation or drying
  • You need to handle high solvent vapor loads
  • You want to replace a steam jet ejector system
  • Your current pump is causing oil contamination issues
  • You need 3,000+ installation-proven reliability
