Holding clamp for holding an angular bottle on a shaking platform of a laboratory shaking device

A holding clamp for holding a bottle with flat side surfaces on a shaking platform of a laboratory shaking device comprising:

• a base plate having a fastening device for fastening the holding clamp on the shaking platform;
• at least two holding arms which protrude from the base plate and which form a vessel receiving space arranged between the holding arms,
• wherein each of the least two holding arms has at least one spacer tab that is arranged entirely outside the vessel receiving space and protrudes from the corresponding holding arm in a direction away from the vessel receiving space;
• and
• a plurality of resilient tensile elements, at least one of said resilient tensile element elements connecting spacer tabs of adjacent said holding arms,
• wherein at least one flat contact surface designed for contact with the bottle is arranged on each of the at least two holding arms,
• and wherein the at least two holding arms are designed such that the flat contact surface can be brought into contact two-dimensionally with one of the flat side surfaces of the angular bottle.
