Process a full rack of Thermo Scientific™ Matrix™ or Thermo Scientific™ Nunc™ tubes in less than one minute with this ergonomic, manual capper/decapper. The Thermo Scientific™ 8-Channel Screw Cap Capper/Decapper is designed to cap tubes to the optimal torque to maintain sample integrity and prevent sample loss during storage. The 8-channel Capper/Decapper is a practical addition to benchtop processing of screw top storage tubes.

• Improves processing throughput of manual procedures with automated column-wise decapping and capping in just four seconds
• Ensures reproducibility by capping all tubes to the optimal torque level specified for the tube
• Allows anyone in the lab to cap or decap tubes with a light weight, easy-to-use and ergonomic design
• Stand allows easy storage of removed caps during sample processing steps
• Virtually always available for use with long battery life and quick recharge time

With recirculation valve and calibration mechanism.

• Quick, easy and precise volume adjustment due to interior scalloped track and practical screw mechanism
• Innovative recirculation valve avoids reagent waste
• No drips after tube has been capped
• Easy calibration adjustment
• High-quality materials (PTFE, PFA, FEP, borosilicate glass, platinum-iridium) ensure good chemical resistance to most acids, solvents and bases
• A positive displacement plunger with PFA seal minimizes the crystallization of liquids and therefore the possibility of the plunger jamming
• Easy to dismantle for cleaning, no tools necessary
• Completely autoclavable at 121 °C
• Can be rotated 360° on bottle
• Certificate of conformity according to DIN 12600 DE-M marked
