Utilizes a locking ring which secures sterile velveteen squares onto a PVC cylinder for easy control of the plating device. To produce replicas, the Petri dish carrying microbial colonies is inverted and lowered onto the cloth surface, then lifted. A fresh sterile nutrient plate is then lowered onto the velveteen surface and lifted, leaving a replica of the original colonies in the new dish. May be disinfected between uses with a brief rinse in 70% ethanol or chlorine bleach Aluminum ring is 10.2cm (4") diameter; PVC cylinder is 6.9cm (2¾") high For use with 90 to 100mm Petri dishes ...

These cloning cylinders facilitate the isolation of individual cell clones, each generated from a single cell, yielding a homogenous population of cells. To isolate a clone, a thin layer of grease is applied to the bottom edge of the cylinder and then inverted over the clone of choice. After adding a small volume of Trypsin or EDTA, the dish is incubated at 37°C (98.6°F) briefly until cells detach. Cells are then collected from inside the cylinder and transferred to another vessel for further growth. Cylinders are tapered so bottom edge is wider than the top ensuring a good ...

For proper sampling of powders, pellets and other friable materials which may become non-homogeneous in bags, this three zone sampler is invaluable. The steel point is inserted through the bag wall. When the sampler is in deep enough to cover the three cells, a half turn of the handle allows samples to enter. The handle is then returned to the original position, the unit removed, and the three samples transferred into containers for analysis. Made of 1.9cm (¾") diameter anodized aluminum with a sharp stainless steel point Port opening: 7.6cmL x 1cmW (3 x ⅜"); port volume; 9cc Distance ...

Hand-held, cordless homogenizer features a simple push in / pull out pestle exchange and is ideal for thorough and faster processing of one to many samples. Matched pestle tips and micro tubes can be used either with the homogenizer or with hand processing. Pestles and tubes assure tight tolerances and thorough homogenization and grinding of materials resulting in optimal efficiency of pellet reconstitution or re-suspension Pestles and tubes are chemical and heat resistant; colorant-free to eliminate potential leaching of heavy metals into samples Tubes have 25% thicker bottoms than ...
