H-Pack

These stain packs are designed to eliminate problems with precipitate, artifacts, drying of slides, and overstaining which causes abnormal staining characteristics of all cellular elements; i.e., false toxic granulation. One adjustment should be all that is necessary to obtain desired color and intensity. Buffer solution compliments individual stain lots to allow consistent staining characteristics. Normal and abnormal WBC's and platelets are vividly demonstrated. Bacteria within leukocytes can be clearly observed. RBC staining gives excellent results of normal cellular elements including all abnormalities and inclusion bodies. Parasites, such as malaria, are well-defined. Bone marrow preps can be stained routinely. Neither freezing nor high temperature causes change in staining ability.

RECOMMENDED USES: H-PACK* & H-PACK*II may be used on all specimens requiring a WBC differential, particularly spinal fluid and nasal smears, and any procedure requiring a Wright counterstain.Other uses include LE preps, parasitic elements such as malaria, thicker buffycoat smears, mature and immature elements of routine bone marrow smears, inclusion bodies such as basophilic stippling, etc. All stain clearly and distinctly.

RECOMMENDED PROCEDURE: Prior to inserting stain pack, all cannulas, tubing and platen surfaces should be cleaned with methanol. For optimum results, new tubing should be soaked in methanol. In order to prevent staining inconsistencies or artifacts due to quality of slides or humid conditions affecting the smear, we recommend fining in methanol. (After fixing, it is not necessary to dry slide prior to insertion into machine.) Crenation of red blood cells can be caused by mechanical changes in preparation of slide prior to staining. H-PACK*: Place into your instrument with the cut out holes facing forward. Insert cannulas through plastic bottles until flush. NOTE: 1f cannulas are dull and do not puncture bottles smoothly, use 18 - 20 gauge needle to puncture bottles prior to inserting cannulas. H-PACK* II: The cannulas are inserted into the appropriate containers of solution. The stain container has two cannulas, one inserted at each end of the container. The buffer and rinse containers have one cannula each.
