Product Description

This Pall 4821A Envirochek Lab Shaker is a high-performance, precision instrument specifically engineered for the elution of microorganisms from Envirochek and Envirochek HV capsule filters. It is the industry-standard equipment required to meet the rigorous demands of US EPA Methods 1622, 1623, and 1623.1 for water quality monitoring.

Built with an industrial-grade motor and a reinforced chassis, this platform shaker provides the consistent, high-speed oscillation necessary for laboratory pathogen recovery. Unlike standard benchtop shakers, the 4821A is designed for continuous reliability in professional environmental testing facilities.

Value Note: This unit offers exceptional value for a laboratory needing to replace an existing unit or expand testing capacity without the $11,000+ capital expense of buying new.

Shipping & Logistics Note

Please Note Logistics Precautions:

At nearly 90 lbs, this is a heavy-duty piece of industrial machinery. To ensure it arrives in its pristine cosmetic and mechanical condition—and to protect the precision internal drive shafts from transit vibration—the following protocols are used:

  • Secure Arm Detachment: The side elution arms will be professionally removed and individually padded/wrapped to eliminate torque strain on the internal motor mounts during handling.
  • Premium Industrial Packaging: The unit will be heavily anchored, boxed, and cushioned to withstand commercial carrier transit safely.
