 1. Center the loop above the sections |  2. Slowly lower the loop over the sections and touch the water |
 3. Gently lift up the loop with the sections in a droplet of water |  4. Lower the loop onto a grid and lift up again |
 5. The grid holds to the loop by surface tension |  6. Lower the loop to the filter paper to remove water |
 7. For coated grids, touch with filter paper to remove water |  8. Separate the grid from the loop with an eyelash |
A useful device, especially for ultramicrotomy. Made of stainless steel, with a fine chuck able to hold thin wires and even hairs as well as needles.
Loops are great for picking up sections in ultramicrotomy and then placing these, free of wrinkles on grids or microscope slides.
Kolle type handle, length 200mm or 290mm with bakelite grip; excellent when heat-sterilising loops or needles. Overall length of nichrome loops, needles and lancets is 50mm.
The lancet is pointed but not sharp. It could be sharpened for dissecting purposes.
These well made nichrome wire (0.25mm thick) loops may be inserted into a needle-holder or glued to any handle. Three different diameter loops are available. All are 63mm long. Pkt/3.

High-strength ABS loops are smooth and flexible to facilitate uniform streaking without damaging the gel surface. Being both sterile and disposable eliminates any risk of cross contamination. All loops are free of lubricants and do not contaminate media.
Available in convenient peel pouch, 20 loops/pouch. Pk/100 = 5 pouches.
Designed for spreading and dispersing liquids across the surface of agar culture plates. These triangle-shaped spreaders have smooth rounded surfaces to prevent any cutting or gouging of agar during inoculation of culture plates. Cross-shaped loop shaft improves grip and assists orientation, making diluting and streaking easy. Autoclavable.
Stout tip for scoring, cutting and bold markings.
Our scribing tools feature the best surface finish attainable. This finish creates an optimum cutting edge ensuring high accuracy and long life. Our scribes are used widely for scoring and scribing on glass and other materials; they are dominant in the Semi Conductor and Fibre Optic markets.
Obtuse (wide) diamond cutting angles are more durable and may be used for scoring and bold markings. Finest markings are made with tools using an acute (sharp) angle. Two of these are in the section with the micro-tools on page T5.
The diamond’s cutting tip is more pointed for finer glass marking and scoring of thin glass. The exposed thin tip is useful for precise positioning; it requires and tolerates low pressure only. Angled shanks facilitate natural pen handling, with the diamond in the vertical position. These pens do not use a refill.
A high quality black pen for marking and cutting glass plates or slides. Durable and functional.
This diamond-tipped scribe tool is made from natural diamond material and a retractable pen body. Tip angle is 105° and refills are available.
SEM: for placing adhesive tapes or sheet material on specimen mounts, punch a conveniently shaped circle.
TEM: punch circles from ACLAR film for growing cells and then mounting on a rod-type holder end, for ultramicrotomy.
AFM: specimen support discs.
Maximum thickness for punching is 1.7mm.

- Sturdy solid construction with firm dependable keys
One Cell Tally Counter
One Counting Unit Tally Counter. A chrome plated with counter with a flange (63.5mm dia.) for desktop mounting. The recording lever is on the right side and the reset knob on the top. The counter is ideal for serial sectioning work. Four digit place.
Two Cell Tally Counter
A counter with two counting keys each with 0 to 999 range with a single reset knob. It comes with removable tabs for top identification.
Five Cell Type Counter/Totaliser
5 Place set to count Basophils, Eosinophils, Seg., Lymphocytes, Monocytes
When a total of 100 cells is counted, a bell rings. The percentage of each type of cell can then be read directly from the window above each key. A simple counter-clockwise rotation of the end knobs will zero all the counts.
Each key has the name and picture of a particular cell above it, representing groups of leucocytes.
Six Cell Tally Counter/Totaliser
A counter with five keys and one totalise unit (0 to 999), which records the total number of strokes made on other keys. At 100 increments, totalising unit rings bell. When totalising unit records 100, each figure corresponding to individual keys automatically displays percentage. Two reset knobs, removable tabs on top of counter provide area for identification of classification being counted.
Eight Cell Type Counter/Totaliser
8 Place set to count Basophils, Eosinophils, Myelophils, Juven., Stab., Seg., Lymphocytes, Monocytes
When a total of 100 cells is counted, a bell rings. The percentage of each type of cell can then be read directly from the window above each key. A simple counter-clockwise rotation of the end knobs will zero all the counts.
Each key has the name and picture of a particular cell above it, representing groups of leucocytes.
Natural rubber blower (eco duster) with 10cm tubing on one end. Used for eco dusting surfaces such as negatives, specimens and microscope parts. A two-way valve prevents suck-back, and the rubber nozzle prevents scratches on the surface to be cleaned.
