SureStand™ Pipette racks accommodate multi-channel pipettes with the stability of a traditional acrylic rack. The “windows” allow the user to insert the multi-channel manifold through the rack, while keeping the body of the pipette stable by securing the pipette at two points; under the finger hook, and near the bottom of the handle.

Excellent for use where horizontal leveling is desirable.

Shoe covers are durable and available in various weights to accommodate specific protection requirements.

Demonstrate the Stirling Design External Combustion Engine with our 18×11 cm working model. The Stirling engine currently is being re-examined as a practical source of power because of its adaptability to almost any fuel. First produced in the 1800’s as a non-electric fan and an automatic hot air water pump, the engine soon became obsolete due to its lack of sufficient power when compared to the newly developed combustion engine. Any fuel can be used with our model, but denatured alcohol is suggested for clean operation.
