Blood typing is a method of classifying blood based on the presence or absence of specific proteins (erythrocytes), on the surface of red blood cells. Blood type, an inherited characteristic, is valuable to know in that it affects medical procedures, such as surgery and transfusions, paternity testing, as well as serving as evidence in criminal investigations. Determining blood type can help provide supporting evidence or eliminate a possible suspect's involvement in crime. This activity includes a teachers manual and a student guide and analysis copy-masters. There is enough material for 15 groups. Note: This activity uses Innovating Science Simulated Blood and is safe for classroom use. Kit Contents: • Blood typing trays • 4 Simulated blood samples: Victim, Suspect #1, Suspect #2, Crime scene • 1 set ABO/Rh blood typing anti-sera • 1 pack mixing sticks

Crime scene investigators examine the scene of possible violent crime for evidence, such as fingerprints, hair, fibre, etc. After collecting the evidence, they notice there is no visible blood. Someone sprays the area with a liquid then turns out the lights. A strange, faint glow appears in certain areas of the scene. Learn how Luminol is used in scenes like this everyday. The special Luminol formulation does not require a separate hydrogen peroxide catalyst. Simply re-hydrate and use with the simulated blood haemoglobin to show your class. This activity includes an instruction manual with suggested activities. There is enough material for several demonstrations. Kit Contents: • 1 bottle Luminol • Re-hydrating Solution • 1 bottle Luminol powder • 1 bottle simulated blood haemoglobin

ABO typing of blood left at the scene of crime can help to narrow down a list of suspects. In this experiment your students will use agglutination to identify the blood group of unknown blood samples as a step to identify a criminal. Kit Includes: instructions, control ABO simulated blood samples, unknown simulated blood samples, transfer pipettes, microtitre plate. All You Need: automatic micropipette (5-50 µL) with tips (optional). For 10 Lab Groups. Complete in 45 minutes.

High quality, non-adhesive plastic tape printed with the words 'CRIME SCENE DO NOT ENTER'. This tape is ideal for crime scene protection or other areas where forensic work needs to be carried out or is still ongoing. Simply unroll the plastic tape and it can then be tacked, stapled, wrapped or tied around suitable objects to create an instant and highly visible barrier. Dimensions (W x L): 75 mm x 100 metres.

Disposable protective suits suitable for forensics work. Size large. Sold individually.

Disposable, blue PVC over-shoes, to protect feet and help prevent cross contamination. Supplied as pack of 10.

Correctly packaged evidence is essential if reliable scientific results are to be obtained. Preserving the chain of custody is important because it maintains the integrity of the evidence. Whenever person comes in contact with piece of evidence, the contact must be documented to prove that the evidence was always accounted for and that no one tampered with it. These specially manufactured bags have many tamper-evident features, including unique bag number and printed label. These bags also have the added benefit of being leakproof.

These plain inch (15 cm) sterile dry swabs on plastic shafts, for specimen/evidence collection, come labelled for inclusion of details such as date, site and time references. Each swab comes in its own polypropylene tube for transport back to the laboratory. Sold as pack of 10 DNA-free swabs, each in its own tube.

These small economy pads leave crisp, clear imprint and dry almost instantly. Only slight residue is left on the fingers which can be removed by rubbing them together or wiping them with towel or cloth. These small pads will give you approximately 1000 individual inked impressions. Dimensions (Dia.): 50 mm.

Pre-cut, uniform quality lifting tape for the ultimate preservation of latent fingerprints, ready cut for convenience. It will conform and stretch and allow fingerprints to be lifted from doorknobs, wooden surfaces, light bulbs etc. Supplied with protective backing sheet. Dimensions (L xW): 120 x 65 mm.

A high quality, dome headed, hand made brush, manufactured by blending up-to-date technology with traditionally crafted skills. These brushes permit even the faintest print to be developed with minimal distortion. Made with soft pony hair, this is a very popular and also economical, fingerprint brush. Each brush is supplied in a clear plastic tube to assist storage and avoid damage to bristles.

A very useful kit designed for students investigating fingerprinting, easily adaptable to suit your needs and lesson plans. Including an information booklet explaining fingerprinting and instructions for use. Kit Contents: • user manual and carry case • Fingerprint powders (4 magnetic, fluorescent and white) • 12 hinge lifters (4 of each black, white and clear) • magnetic wand • fingerprint brushes • 1 pair of protective gloves • protective apron • protective face mask.

Evidence left behind at a crime scene can identify a potential culprit. Even in this age of DNA, fingerprints and blood stains are still important at helping to identify a criminal. In this experiment, your students will solve crime by dusting for fingerprints and use fluorescent dust (not included) to search for and identify trace amounts of blood. Kit Contents: • instructions • brushes • magnifying lens • fingerprint cards • black dusting powder • fingerprint lifters All you need: alcohol, fluorescent dust, and long wave U.V. light. For 10 lab groups. Complete in 50 minutes.
