IKA HS 250 basic Platform Shaker

The IKA HS·250 basic is a compact platform shaker designed for uniform mixing and agitation of liquids in flasks, bottles, tubes, and other lab vessels. It’s ideal for biology, chemistry, microbiology, and routine mixing workflows where consistent reproducible shaking is needed.

Key Features
Movement type: Horizontal back-and-forth / orbital platform action suitable for gentle mixing of suspensions and solutions.
Speed range: 0-500 rpm (adjustable) for a wide variety of shaking intensities.
Shaking distance: about 19 mm (HS 250 B with AS 1.9 universal attachment) — provides effective reciprocating motion for thorough mixing.
Control: Analog speed adjustment (knob) — simple and robust operation.

Platform & Compatibility
Interchangeable platform: Accepts a range of holders or clamps for different vessel sizes (attachment sold separately).
Suitable for mixing flasks, bottles, and tubes in labs working with cell cultures, suspensions, reagents, and solutions.
Quiet, stable mechanical design ideal for everyday shaking tasks.
