Color coded for easy product identification

Each loop size and model has a unique color code to facilitate easy recognition and to distinguish different products.

Ultra smooth loop surfaces allows easy streaking

No rough plastic edges, flashing or burrs on the loop head means smooth, problem free planting and streaking of cultures. Loops do not cut or gouge the agar surface during streaking.

Choice of rigid or flexible loops

Copan manufactures two lines of 1 µl and 10 µl loops using two different plastic compounds: soft-flexible plastic or harder rigid plastic to cater to different applications and microbiologists’ preferences.

Free of lubricants, oils and electrostatic charges enables consistent wetting
and complete liquid transfer

Eliminating these factors, allows consistent wetting of the plastic and enables the correct surface tension on the inside walls of the loop. Correct size droplet is formed and complete transfer of this volume takes place without leaving behind any beads of liquid.

Hexagonal loop shaft improves grip, assists orientation and makes diluting and streaking easy

When viewed in cross section, the shafts of the Copan loops have a hexagonal shape creating a handle with six flat surfaces. This design facilitates maximum grip and easy orientation of the loop head. When planting and streaking cultures for isolated colonies, the hexagonal handle allows the microbiologist to quickly and easily rotate the loop head from one flat side to another or from flat side to the edge of the loop. Diluting streaks for isolated colonies can be performed very quickly and smoothly through this easy action. The hexagonal loop shaft helps the microbiologist index the first streak then to rotate the loop head to achieve the second, third and fourth dilution streaks.

Available in Zip-Lock Resealable Pack, Medical Peel Pouch or Individually Wrapped

Loop Accuracy Certified Using Evans Blue Dye Method

The Volume Delivery Consistency of each production lot of loops is quality controlled and certified using the Evans Blue Dye Method. This method measures the actual volume of liquid transferred by a loop.

Certification of Calibration in Every Pack

Choice of Regular or Mini-Needle

Copan offers a choice of two types of plastic disposable needles: Regular and Mini-Needles. The total length of the Regular Needle product is 20cm and it has a 1.45mm diameter needle shaft. Regular Needles have a much longer reach and a broader needle shaft in comparison with the Copan Mini-Needles. Mini-Needles can be used for more delicate operations, they have a more slender design and the needle shaft itself is narrower and more flexible than the Regular Needle. The total length of the Mini-Needle product is 15cm and the needle shaft has a 1.15mm diameter.

Choice of features -flexibility, thickness or length

The users can choose which features best suit their specific task – flexibility, diameter of the needle or the total reach.
