Test resistors and calibration solutions to test the meters with conductivity function as well as to calibrate the system from the device and conductivity measuring cell

• Optimal measuring safety by PTB/NIST traceable standard solutions
• Easy device check by highly precise test resistors
• Pharmacopeia conforming test kits

This novel stirring system has been conceived to mix low viscosity fluids as well as highly viscous media at slow speeds. Its special design creates inherent dynamic currents to produce perfectly homogeneous mixing results in very little time. Additional components like baffles, bottom bearings, etc. are not needed.

Advantages at a glance:

• suitable for low to highly viscous fluids
• stirs media containing solids and fibres without any difficulty
• gentle, low-shear stirring, due to slow stirring speed
• constant product temperature, with no heating effect
• short mixing times as the entire contents of the container are agitated
• no air addition, no foaming
• no baffles required
• low gear wear due to balanced forces
• minimal power consumption thanks to low speeds and short operation times
• easy cleaning
• material no. 1.4404

• a single stirring zone, near to the container base, ensures easy mixing of settled residues, e.g. in flow-through mixing containers
• no baffles required, thus no additional sources of ignition

BSR series stirrers perform routine mixing tasks up to 200 l.

General specifications:

• operating pressure max. 6 bar
• air consumption 800 l/min. at 6 bar
• power output 640 W at 6 bar
• clockwise rotation
• ATEX rating to Ex II 2G Ex h IIC T5 Gb

• all-stainless steel housing
• continuously adjustable speed control valve
• spherical clamping device with support arm diam. 16 mm, length 200 mm
• floor stand with rod (height 1000 mm, width 600 mm) and bosshead
• plug-in connector DN 7.8
• silencer
• output shaft L 32 mm x diam. 14 mm

Double-Cardan-Coupling DCK I:
With 8mm dia. hexagonal input drive receiver and 6mm square socket drive output.

Fixed-diameter connection between motor and stirring shaft. Suitable for use in potentially explosive atmospheres (ATEX). Material no. 1.4404

The dissolver stirring rotor creates a radial flow with high turbulence. The mixture is drawn from top to bottom. High shear forces are created at the dissolver disk, which provides effective particle reduction. Recommended for medium to high speed operations.

Stirrer head with a permanent magnetic coupling for mixing applications under vacuum. No straight-through shaft, no shaft sealing rings required as the torque is provided contactless by magnetic force.

Speed: 2500 rpm
Material: 1.4435 (AISI 316L)
Seal: FKM
Bearing: Ball bearing made of stainless steel

Drive shaft supplied with 6 mm external square stub.

Used as a shaking platform. For the slow moving of e.g. nutrient media solutions in Petri dishes and flasks.
