Features of titrets technology: Dependable, sealed single-use titrants Fast, easy procedure, no need to count drops No burettes or other equipment necessary Perform a titration ANYWHERE

Designed to measure conductivity in water analysis, biology, chromatography, food, electronics, dairies, and PC-board rinsing, the conductivity meter provides results in conductivity (micromhos/cm and microsiemens/cm), resistivity (megohms), and dissolved solids (parts per million).

Based on the Atmel AT91SAM3X8E ARM Cortex-M3 microcontroller.

This ripple tank is transparent, acrylic plastic and supported in a sturdy plastic frame.

The skull of the Bullmastiff reflects its canid origins and breed characteristics, being 60% Mastiff and 40% Bulldog; a short muzzle preferably with a level or slight under bite like a Bulldog, and a heavy, square skull with moderately wide set eyes like a Mastiff. This skeleton would be a great addition to any veterinary program or comparative anatomy program focused on canid evolution.

These all adds up to a comprehensive storage system.

The FDA-approved, Saniclave 102 is fashioned with a simple push-button operation.

Apparatus for measuring the time it takes for a ball to fall a certain distance using a digital timer. Very easy to set up and use but nevertheless highly accurate. Includes 3 steel balls. A micro-magnet holds the ball in its start position. Three contact pins under the release mechanism ensure that the start position of the ball can be reproduced and act as the contacts of a switch that opens when the ball is released, thus triggering the beginning of the timing measurement. When the ball strikes the contact plate at the bottom, the timer is stopped. The ball is also held firmly on the plate so that it does not bounce. The height through which the ball drops can be adjusted to a fraction of a millimeter and read off a scale on the column.

Mounted on molded plastic base, the unit consists of a base into the top of which may be screwed one of a set of four vases of differing shapes. An aperture in the bottom has a thin rubber diaphragm across it, bearing upon the short arm of the lever pointer. A moveable index on the vertical rod enables the height of water in vases to be set at same level. The apparatus is mounted on moulded plastic base that measures 25 x 17.5cm. The experiment is performed by screwing in each vase, in turn, and filling with water to the same level. It will be seen that the given height of water will result in the same deflection of pointer whatever shape of the vase.
