• YCW-012S shaking water bath — GEMMY Industrial: A reciprocating shaking water bath built on a microprocessor digital controller that displays the actual bath temperature and holds uniformity to +/-0.1 degrees C. Shaking stroke is set on a control knob from 20 to 200 rpm, produced by an induction motor giving a 20 mm circular motion at 0 dB. Tube racks and the flask platform can be raised, lowered and removed to suit different vessel lengths, or taken off entirely when shaking is not wanted. An audible over temperature alarm cuts the power at 2 degrees C above the set point, and temperature recalibration is available when the actual reading drifts from the display.

It works from 5 degrees C above ambient up to 100 degrees C for biological, clinical research, medical, biochemical, industrial and teaching laboratories. The moulded tank has rounded corners and seamless stainless steel sides for even circulation and easy cleaning, and a rotating stirrer directs flow around the tank to improve uniformity. Concentric ring covers are offered to cut heat loss when flasks are suspended in the bath.
• KHT-410E haematocrit centrifuge — GEMMY Industrial: A micro haematocrit centrifuge for packed cell volume work, used in biochemistry, microbial immunity genetics, blood separation and general clinical testing to establish the percentage of red blood cells against whole blood, which can indicate anaemia or polycythaemia. GEMMY states that all models in the range run at a fixed 12000 rpm apart from the PLC-012 and PLC-012E. The time is set and the run started with the START button, the rotor lid must be closed before spinning, and a reading scale is supplied so the capillary tube can be read directly. EPDM is used for the rotor gasket to extend service life, and a safety device cuts the power if the lid is opened during operation.

Low moisture content suits hydrophilic and moisture sensitive powders and functional fillers, and GEMMY reports no cracking even at zero per cent humidity and stability below 65 degrees C without refrigeration. Sizes 00#, B#, 0#, 1#, 2#, 3# and 4# follow conventional dimensions so existing filling machines do not need altering. GEMMY publishes no model code for this item.
• VM-300 vortex mixer — GEMMY Industrial: A benchtop vortex mixer running to 3150 rpm with a single tube head, or 1800 rpm with the 3 inch pad, driven by a 5.6 mm eccentric. Two mixing heads are interchangeable: a 26 mm diameter rubber cup for conventional single tube work, and a 3 inch platform pad for multiple tubes or a flask. Operation is either TOUCH for intermittent running, where stirring intensity is controlled by the pressure applied to the pad, or SWITCH for continuous mixing at the flip of a switch. The unit measures 130 x 165 x 180 mm and weighs 5.0 kg, heavy enough to resist slipping and creeping under vibration.

• VRN-200 orbital shaker — GEMMY Industrial: An orbital shaker with a 263 x 263 mm platform and a 21 mm orbit, set between 75 and 250 rpm or supplied to run at a fixed 130 rpm. It is intended for long term uniform mixing of test solutions in micro-titration assays and for haematology, urology and EIA or ELISA immunology work, including Alpha, Kline, Mazzini, syphilis and pregnancy applications. A textured non-slip rubber foam pad grips printed well slides, culture plates, flasks and tube racks by friction, and the contoured platform holds six plates. The single eccentric drive carries 1 kg at 100 rpm, and a lit ON/OFF switch shows at a glance whether the unit is running, either continuously or on a timer up to 60 minutes.

Speed is set from 75 to 250 rpm, or the unit can be supplied at a fixed 130 rpm, on a single eccentric drive rated for 1 kg at 100 rpm. The contoured platform takes three 96 well microplates, and the textured non-slip rubber foam pad also grips printed well slides, culture plates, flasks and tube racks. It runs continuously or on a timer for intermittent shaking up to 60 minutes, with a lit ON/OFF switch.
• VRN-480 orbital shaker, rotator — GEMMY Industrial: The heavy duty shaker in the range, with a 422 x 282 mm platform, a triple eccentric drive and counterbalance that hold a vibration free 25.4 mm orbit at speed even under heavy or unbalanced loads. Solid state control covers 40 to 400 rpm and the platform carries 15 kg at 100 rpm, with speed shown on an analogue tachometer or a three digit LED so runs can be repeated accurately. The platform turns on six permanently lubricated sealed ball bearings, and the precision machined drive housing sits on four cushioned feet that stop the unit creeping. Flask platforms are listed as GE-125-15 for fifteen 125 ml flasks, GE-250-11 for eleven 250 ml flasks and GE-500-06 for six 500 ml flasks, and timed operation runs up to 180 minutes.

GEMMY quotes temperature uniformity of +/-3.0 degrees C and stability of +/-0.5 degrees C, both measured at 180 degrees C, with the timer only starting once the actual temperature reaches 2 degrees C below the set point. Double wall construction with heavy gauge glass fibre insulation retains heat, and adjustable fresh air inlet ports at top and bottom control the amount of convective air. Safety cover includes an over temperature alarm and cut-out at 10 degrees C above the set point and an independent safety switch that removes power at 220 degrees C if the primary control fails.
• YCO-N01 analogue hot air oven — GEMMY Industrial: The gravity convection oven in GEMMY's range, offered where cost is the deciding factor and where accurate temperature control and uniformity are not critical, or where samples must not be disturbed by air movement. Temperature is read directly from a mercury thermometer mounted on the top of the cabinet, and control is by hydraulic thermostat sensor. The door lock is a newer design intended to be easier to open and close, and the formed door gasket limits heat loss. GEMMY publishes no numerical specification table for this model.
• DB-005 dry bath incubator, block heater — GEMMY Industrial: The compact analogue dry bath in GEMMY's range, weighing 2.5 kg with a 200 W heater and a maximum of 105 degrees C, holding uniformity at 37 degrees C to 0.3 degrees C under PID control. Temperature is set on an analogue control and read from a thermometer, with an over heat alarm fitted. Applications listed include incubating DNA specimens, cross matching and screening in the blood bank, incubating melted agar, enzyme assays, digestions and milk residue tests, as well as serology, haematology, pathology and biochemistry work. Interchangeable heating blocks accept test tubes, cuvettes and microcentrifuge tubes, each with a well for a removable thermometer, and a solid block with no holes turns the unit into a hot plate.
• DB-006 dry bath incubator, block heater — GEMMY Industrial: The larger analogue dry bath, 3.5 kg with a 450 W heater reaching 105 degrees C, with uniformity at 37 degrees C quoted at 0.5 degrees C under PID control. Setting is analogue with a thermometer readout and an over heat alarm. It covers the same bench work as the rest of the DB range: incubating DNA specimens, blood bank cross matching and screening, melted agar, enzyme assays, digestions, milk residue tests, serology, haematology, pathology and biochemistry. Heating blocks are interchangeable for test tubes, cuvettes and microcentrifuge tubes, each with a thermometer well, and a solid block converts the unit to a hot plate.
• DB-006E dry bath incubator, block heater — GEMMY Industrial: The digital dry bath in the range, with digital setting, an LED digital readout and a digital 99 hour timer, which the analogue DB-005 and DB-006 do not carry. The 450 W heater runs to 99 degrees C with uniformity at 37 degrees C quoted at 0.5 degrees C under PID control, and an over heat alarm is fitted. Net weight is 5.5 kg. The same interchangeable heating blocks accept test tubes, cuvettes and microcentrifuge tubes, each with a well for a removable thermometer, and a solid block turns the unit into a hot plate.
• IN-601 laboratory incubator — GEMMY Industrial: A laboratory incubator offered in six capacities from 34 to 150 litres, working from ambient plus 5 degrees C to 75 degrees C, in either an analogue or a digital build. The analogue version uses ON/OFF control with a mercury thermometer on the top of the cabinet and natural gravity convection, giving uniformity of +/-5.0 degrees C and stability of +/-3.0 degrees C at 37 degrees C. The digital version uses microprocessor PID control with forced convection, tightening uniformity to +/-3.0 degrees C and stability to +/-1.0 degrees C at 37 degrees C, and cuts out at 4 degrees C above the set point rather than at 80 degrees C. On the digital model the mechanical 180 minute timer starts only once the set temperature has stabilised, shows END when the cycle finishes, and stores the temperature and elapsed time if the door is opened mid run.
