LABWARE Test Tubes TEST TUBE GLASS TYPES SODA GLASS test tubes are suitable for general laboratory work and can withstand moderate warming (e.g. in a water bath) but NOT direct heat. They are an economical choice for situations where direct heat is not involved. NEUTRAL BOROSILICATE GLASS test tubes can withstand moderate temperature changes but should not be used straight from cold to a hot Bunsen flame without pre-warming first (e.g. by moving tube in and out of a Bunsen flame). These glass tubes have good chemical resistance and are a cheaper alternative to borosilicate glass, when only gentle heating is required. BOROSILICATE 3.3 GLASS test tubes are suitable for most laboratory applications and may be used for heating samples up to boiling point etc. This glass type has very good heat and chemical resistance. CARE! With all test tubes and other types of glassware, continuous intensive heating of the same spot will result in softening and deformation of the glass, regardless of glass type or brand.

ST14255 £21.59 ea TH15584 £9.38 ea An explanation of why laboratory thermometers can appear inaccurate when measuring water boiling.* Water boils at 100°C only under controlled laboratory conditions. To accurately test a thermometer at 100°C in a UKAS Laboratory, our supplier uses an oil bath controlled by a calibrated master platinum resistance thermometer, and controls environmental issues such as ambient temperature, pressure and humidity with air conditioning and conversion tables. This situation is impossible to replicate when boiling water in a beaker in a classroom environment. • Tap water contains impurities which will elevate or depress its boiling point. • Atmospheric pressure has a similar effect. • It is necessary to know whether the thermometer is a partial or total immersion model and to use it correctly; for instance, the emergent stem of a partial model when exposed to steam will be heated inappropriately and consequently over-read. Thermometers are designed to be at their most accurate at the mid range position. Therefore, if 100°C is the important temperature, the appropriate model would be one covering -10/150°C or -10/200°C, rather than the usual -10/110°C types found in schools. In practice, rather than attempting to prove that water boils at 100°C, teachers could use the visible discrepancy apparent during classroom experiments to illustrate the effects of the factors listed above! * Information provided courtesy of Brannan & Sons Ltd.

GLOSSARY MECHANICAL STAGE BASE A mechanical stage may be fitted or supplied with the microscopes and retains the prepared slide. Mechanical movement allows the slide to be manipulated in ‘x’ and The base normally contains the illumination system ‘y’ directions.

There are different types of condenser. NOSE PIECE The stage condenser N.A 0.65 incorporated in the stage. The Abbe condenser N.A 1.25 this is under the stage and is able to focus light.

OBJECTIVE LENSES There are different types of diaphragm used in microscopes. The disc diaphragm is a revolving plate with a series of different sized holes fitted The main objective lenses are 4x, 10x, 40x (spring loaded) retractable and 100x beneath the stage.

(Achromatic Superior Contrast) or plan Achromatic. The terms refer to optical EYEPIECE correction. OIL IMMERSION OBJECTIVE A primary image is formed by the objective lenses: the eyepiece forms a secondary image, which is what you view. The 100x objective is lowered in to a drop of immersion oil placed on the slide. Oil Two types of eyepieces are commonly available. immersion lenses should be used in conjunction with an Abbe condenser. The oil is Widefield – large field of view. the same refractive index as the objective lens and cover slip. Huygenian – narrow field of view, graticules can be fitter to appropriate eyepieces. PARCENTERED The eyepieces fit onto the eyepiece tube or ocular tube. FIELD OF VIEW Applied to each objective viewing – the same centre point in turn. PARFOCAL The area which is seen through the eyepiece when the microscope is in focus. FOCUSING The ability of the microscope to stay in focus when the objectives are changed. Applies when high magnification to low magnification is selected. There are two types of focusing mechanisms. RMS Rack and pinion – separate coarse and fine focusing controls. Coaxial focusing – comprising both the coarse and fine focusing controls around a Royal Microscopical Society. common axis.

MICROSCOPES Motic Microscopes Digital Microscopes continued MOTIC Wi-Fi DIGITAL This range of digital microscopes are both affordable and MICROSCOPES up-to-date requirements for the needs of today’s young scientists. Adaptable to the new Moticam X camera which has These microscopes require two power supplies: one for the illumination added WiFi features, bringing technology to the classroom. (supplied) and USB power for the camera. You can use either a computer USB port, or a USB plug‑top power supply for this. BA50-X WiFi Digital Microscope The USB port on the Wi-Fi microscope is for power only – the image is not transmitted over USB. Timstar are pleased to introduce the new, versatile BA50-X WiFi digital microscope, which represents the latest in Educational technology. Like the BEST Moticam X, this digital microscope transmits live images to wireless laptops, iOS or Android Tablets. Featuring high-speed, full resolution imaging SELLER technology built into the head of the microscope, the BA50-X can be used as a normal microscope with the built-in eyepiece, or used to share live images with your class, using WiFi tablets or Windows Laptops. Please note: connection to the microscope camera is exclusively over WiFi, using the microscope’s own ad hoc network. The USB port is for power only.

Motic Play and Educator are imaging software tools designed for children using digital microscopes. The software uses pictures and sounds to help children capture and edit still images and videos. The software makes science fun for children and will allow them to capture and measure microscopic images and videos. They can add text and icons or apply effects such as “mosaic” or “emboss” to the images. Children can rotate the pictures, paint them, turn them to gray-scale and much more. The images they create can be shared by e-mail or exported for printing. The software allows children to imagine and create a variety of fun science-related images with step-by-step picture help sections that cover all of the functions. The Play version is designed for more Primary School level whereas Educator is for Key Stage 3 and beyond. The DS-2, DM-52 and DM-111 are all supplied as standard with this package. Motic Images Plus 3.0 – a fresh approach for powerful microscopy software. Motic Images Plus 3.0 is the first all-new redesign of this popular software, which includes all the major updates in digital microscopy. Unlock the potential of your microscope and capture, measure and quantify the image that you see through the eyepiece, onto a computer screen. The software comes with an interactive white balance and background balance in order to optimize the image background in terms of colour temperature or shading. Existing users with version 2.0 can upgrade to Images Plus 3.0 free of charge. • User-friendly interface • Multi-platform: Identical interface on Windows, Apple or Linux • Intuitive & Customizable OS • Live measurements • Empowers your microscope to be a more efficient scientific tool • Multilingual software; simple to change between languages • Multilingual software; simple to change between languages • Free upgrade from Images Plus 2.0 to 3.0 448 …inspiring tomorrow’s scientists through practical science.
