block scientific is pleased to provide a wide range of products from helena. the products we offer include, but are not limited to the following.
cascade m-4 coagulation analyzer
cascade m-4, 4-channel analyzer, 6-line screen, 110v / 220v. these are ideal for all routine clotting assays – pts, aptts, thrombins, fibrinogens and factor assays.
thromboplastin reagent, 200 tests, 10 x 4 ml
thromboplastin reagent is prepared from rabbit brain tissue for use in automated, semi-automated and manual pt tests and assays for factors ii, v, vii and x. reagent is lyophilized; reconstitute with water. reconstituted stability is 7 days at 2-8°c. international sensitivity index (isi) values are between 2.0 and 2.5.
also available: 10×10 ml, 10x20ml
calcium chloride, 10 x 10 ml
aptt-es reagent is an optically clear, stabilized liquid with a soluble ellagic acid activator. it’s extra sensitive to heparin, lupus-like anticoagulants, and factor deficiencies.
aptt-sa, 10 x 10 ml
aptt-sa reagent, 1000 tests
0.025 m calcium chloride, 1000 tests, 10 x 10 ml
aptt-sa reagent uses a soluble ellagic acid activator to provide a more optically clear reagent, an important consideration for automated analyzers with sensitive photo-optical detectors. ellagic acid reagents also offer excellent precision and sensitivity. aptt-sa reagent is a stabilized liquid available in three convenient kit sizes.
