A reflux condenser with a cooling (heating) jacket and a valve system is usually used in distillation plants to separate liquids with different boiling points. Core 60/46 and coupling 29/32 are the sizes and types of connecting parts of the dephlegmator. The 60/46 core indicates the diameter size of the internal part of the reflux condenser, where a connection of 60 mm external diameter and 46 mm internal diameter is used. The 29/32 coupling indicates the size of the connection hole or reflux condenser pipe, where a connection of 29mm outer diameter and 32mm inner diameter is used. Such connection sizes can be standard and determined in accordance with the technology and equipment used.

The mixer operates in a speed range from 50 to 1500 rpm, the maximum heating temperature of the working surface is 500 °C. The heating plate includes a base made of stainless steel and a working surface made of fire-resistant glass (glass ceramics). At temperatures above +550 °C, automatic overheating protection is triggered and turns off the heating. The device is equipped with an LCD screen to display set and actual temperatures, rotation speeds and additional animated icons. There is a timer for the specified operating time of the mixer; its maximum value is 990 minutes. There is a function for automatic detection of armature rotation failure. When the device detects an armature failure, the rotation stops. Then rotation resumes, but the speed is reduced by 10%, followed by restoration of the rotation speed to the user-specified parameters. A stall occurs if the armature becomes disengaged with the stirrer magnet and stops rotating. Disruption can occur for various reasons: the rotation speed is too high, the viscosity of the medium has changed during the mixing process, etc. When the power of the device is turned off, the set values of temperature, speed, timer time and the mode of detection (determination) of failure of armature rotation are stored in non-volatile memory. The armature rotation speed and heating temperature are set using two rotating knobs. Characteristics Motor power 16 W Range of operating speeds of the motor shaft, 200-1500 rpm Discreteness of setting the specified speed of rotation of the motor shaft, 10 rpm Resolution of displayed motor shaft rotation speed, 10 rpm Connection – external temperature sensor PT1000 (sold separately) Power consumption, 20 W Dimensions, weight Overall dimensions LxWxH, 380x220x120mm Working surface size, LxW, 200x200mm Maximum anchor length, 80mm Device weight 4.4 kg Contents of delivery Stirrer without heating PL-R-basic Operating manual combined with passport Anchor for stirrer in fluoroplastic sheath 8*50 mm Power cable with Euro plug

The Primelab borosilicate glass reaction flask is an essential glass vessel used in scientific research, educational institutions, laboratories and industries. It is practically impossible to do without it when carrying out chemical reactions. The flask is made of transparent borosilicate glass, which allows you to observe the reaction process in real time. At the same time, it has a long service life and wear resistance. Suitable for heating and cooling contents as it is thermally stable. The PrimeLab company is ready to manufacture reaction flasks in any quantity to order. The order fulfillment time depends on the volume.

An exhaust cabinet for heating furnaces. The chamber of the laboratory fume cupboard is sheathed with ceramic granite (30x30 cm) from the inside. The camera housing is made of chipboard (16 mm). The base of the cabinet is an all-welded metal frame in powder coating. The side laminated panels (chipboard with a thickness of 16 mm) are edged along the facade with a durable PVC edge with a thickness of 2 mm, which increases their impact resistance and mechanical strength. Exhaust laboratory cabinets are used when working with toxic and harmful volatile materials, with clean materials, with dissolution or decomposition under heat treatment, during sample analysis and many others. The standard version of the cupboard has a countertop of the exhaust laboratory cabinet made of ceramic granite. Porcelain stoneware (tile) has a number of advantages: it is resistant to prolonged exposure to acids, alkalis and organic solvents, it has higher mechanical resistance, it withstands high temperatures, it has limited resistance to hydrofluoric acid. Many possible variants of table tops resistant to aggressive materials make the fume cupboard indispensable for any laboratory. The complete set of the fume cupboard includes: a working chamber: a lifting screen with counterweights, a granite table top; an exhaust pipe on the cabinet lid with a diameter of 150 mm; grounded and not grounded electrical outlets (2 items); powder-coated metal frame (25x25 mm); legs height-adjustable within 15 mm.
