About Direct Drive Stirrers

AC/DC Lab Stirrers

Designed to meet requirements of laboratories demanding wide flexibility of stirring operations, these stirrers are available in various models. Choice of model will be dependant on the batch size / volume to be stirred.

Salient features:

	Multipurpose stirrers for general purpose & PUF stirring
	Heavy duty stirrers for pilot plant, bench scale process & small batch production
	Models also available with digital speed indicator for speed indication & process validation

PMDC Lab Stirrers
PMDC Stirrers are specially designed for routine laboratory work, research and development, QA analysis and sample preparations. Stirrers have uniform speed control with digital RPM indicator which gives speed read outs, valuable for applications where process validation and reproducibility is required.

RQ-121/D, RQ-126/D and RQ-129/D models use direct drive motors & are ideal for day to day laboratory use with aqueous & low viscosity liquids such as light oils.

Salient Features:

	PMDC motor for powerful stirring			Hollow shaft in Geared models permitting height adjustment
	Reliable performance even in continuous use			Chuck for easy interchangeability of shaft
	Stepless electronic speed regulator with digital display			Stirring shaft SS 316; Retort Rods SS 304

FAQs of Direct Drive Stirrers:

Q: How do I operate and adjust the speed on the Direct Drive Stirrer DDS-02?

A: The DDS-02 features a variable speed control that allows you to precisely set the stirring rate up to 3500 RPM. Simply adjust the speed controller knob until the desired consistency is achieved for your solution. Always start at a lower speed and gradually increase as needed.

Q: What types of solutions is this stirrer suitable for mixing?

A: The Direct Drive Stirrer DDS-02 is designed to handle viscous solutions up to 2 liters, making it ideal for laboratory samples requiring thorough mixing, including chemical, biological, and analytical preparations.

Q: Where can the DDS-02 stirrer be installed for optimal performance?

A: It is intended for table-top mounting, which ensures stability during operation. Place it on a flat, secure laboratory workbench, with access to a 220 V power source and adequate ventilation.

Q: What safety features are included in the DDS-02 model?

A: The stirrer is equipped with overload protection to prevent motor damage during intense use. Additionally, its IP21 protection class guards against intrusion by solid objects and limited moisture, enhancing operational safety.

Q: When should I use the continuous duty function on this stirrer?

A: Continuous duty is recommended for extended mixing protocols where uninterrupted agitation is essential, such as during prolonged emulsification or when mixing large volumes consistently.

Q: What are the benefits of the stainless steel impeller for laboratory applications?

A: Stainless steel impellers offer superior resistance to corrosion, chemical reactions, and wear, ensuring hygienic operation and longevity in laboratory environments.
