PNEUMATIC EGG PUNCH

Hand-held pneumatic egg punch produces a clean, circular fracture in embryonated chicken eggs. The lab technician holds the egg punch in one hand and centers the bottom of the punch over the end of the egg. As the trigger button is pushed and released, the knife makes a 1" diameter cut, and the circular cap of the egg is ready to be lifted off. The lower air sac membrane is exposed, intact and readily accessible. Because the unit is hand-held, it can be used at any convenient height. Each unit includes brass fittings and six feet of tubing to connect to a compressed air source.
The egg punch may be sterilized by suitable disinfectants or by heating in dry air. It should not be totally immersed in liquids.

NAIL HOMOGENISER

Hand-held attrition mill that easily pulverizes small nail samples for more reliable dermatological testing. When treated with 10% KOH, the micronized samples spread out rapidly and evenly beneath a cover slip, making study easier and more accurate. The homogeneous sample derived from using the Nail Homogenizer increases the chances of discovering fungal hyphae in a specimen. Additionally, using pulverized samples increases the possibility of culture isolation by permitting greater numbers of potentially viable fungal cells to come into direct contact with the isolation medium.
Pulverizing in the Nail Homogenizer is a simple task, and laboratory safety is improved since no sharp-edged tools are required. The technician places a specimen in the mill cavity, presses the two mill halves together, and rotates the halves in opposite directions several times. This process is successful with other tough, resilient materials in addition to nail clippings.
Cutting head inserts are replaceable, and the entire unit is autoclavable in preparation for the next sample.

ANALYTICAL MILL

Batch mill for 2 different grinding procedures:
Impact grinding of hard, brittle or non-elastic grinding materials with high-grade stainless steel beater. This beater can be used for a Mohs hardness up to 6 (incl. with delivery).
Cutting grinding for pulverizing soft, fibrous materials with a cutting blade (not incl. with delivery).
- Moist and gluey materials can be pulverized by adding water
- Grinding chamber made of Tefcel (PTFE, glass fiber-reinforced) with stainless steel inlet (1.4571), useful volume 80 ml (incl. with delivery). For embrittlement of grinding materials with liquid nitrogen in the grinding chamber
- Optionally, a 250 ml grinding chamber is available
