Whatman™ Grade 17 Chr filter circles and Antibiotic Assay Discs are ideal for determining the type of causal agent of infectious diseases and for checking their sensitivity to antibiotics and chemotherapeutic agents in vitro by means of the inhibition zone determination method. The antibiogram allows rational and selective chemotherapy. The test discs can be coated with chemotherapeutic agents, placed on the innoculated nutrient agar and incubated. The size of the inhibition zone is a measure for the effectiveness of the substances.
A blood collection tube is a pre-sterilized glass or plastic tube with a fixed rubber stopper, containing a vacuum which facilitates the draw of a predetermined volume of blood or liquid. Blood collection tubes are predominantly used for blood sample collection in venipuncture, serum separator tubes. Some blood collection tubes tubes will contain additives designed to coagulate, stabilize or preserve the blood sample prior to clinical lab testing. Most blood collection tubes (like BD Vacutainer tubes) are available with a safety rubber stopper and a variety of marking and labeling options. Various brands and sizes are available which will allow your clinical lab to draw different volume sizes of blood.
Blood collection tube needle holders (Vacutainer needle holders) are made of unbreakable polypropylene (PP) and are designed and priced to be disposable. These single-use vacuum blood collection tube holders complete the blood collection assembly when combined with appropriate needles and evacuated blood collection tubes. They may be used only once and then are to be discarded with the needle attached. This eliminates the hazards associated with reusable needle holders. These needle holder fit both 13mm and 16mm blood collection tubes and all common needle units.
Microhematocrit testing of blood requires the use of blood capillary tubes which are used in the procedure for determining the ratio of PCV (Packed Cell Volume) of red blood cells to the volume of whole blood. This is performed by centrifuging the blood within the microhematocrit blood capillary tubes. Capitol Scientific offers both pre-treated and non-treated blood capillary tubes from a variety of manufacturers to suit your serology testing needs.
Patient blood is routinely tested to determine what blood type the patient has. Blood Types "A", "B", and "O" are the main types of blood. Blood typing tubes are used by clinical laboratories to determine the type of blood a patient has as well as to detect the presence of unexpected antibodies which may cause reactions with donor blood. Blood typing tubes are also used for blood compatibility testing which requires the clinical analytical testing of both patient and donor blood to ensure that the two blood samples are compatible in the event of a needed blood transfusion. Capitol Scientific offers a wide variety of blood typing tubes from various manufacturers in different sizes.
Westergren ESR Determination Tubes and Kits are designed for blood testing of erythrocyte sedimentation rates or ESR. ESR is the sediumentation rate of blood cells within a one-hour period of testing. The Westergren ESR test is a measurement of inflammation and is one of the most common blood test known in hematology. The Westergren ESR Test is performed by inserting anti-coagulated blood in to the Westergren ESR tube and then the rate at which red blood cells fall (or sediment) is measured and recorded in millimeters per hour.
Capitol Scientific offers a full line of Westergren ESR Determination tubes and kits from Kimble, Globe Scientific and other manufacturers to suit your hematology laboratory needs.
