Safe and effective protection from radioactive compounds is an essential requirement in certain life science research laboratories, for example those handling either beta or gamma emitting materials used in the detection of nucleic acids and proteins, or other techniques, such as radioimmunoassay and metabolic studies. Cleaver Scientific (CSL) manufactures the largest range of acrylic radiation shielding products from their facility in the UK. CSL has developed a wide range of over 120 Radiation Safety Products which provide optimum protection for laboratory personnel involved in applications where either Beta or Gamma emitting compounds are used. The range includes: shields, boxes, racks, waste bins, spillage trays and cabinets. Flexibility and low cost are important requirements for many customers and CSL meet this demand by offering custom-built shields and boxes which are manufactured in a variety of shapes and sizes to suit most applications and budgets. The storage boxes are ideal for waste material and samples. Interchangeable inserts hold various sizes of tubes, such as micro-centrifuge, centrifuge tubes, scintillation vials, universals, cryotubes and falcon tubes.
