Perform Routine Pipette Tests in the Lab Efficiently

When carrying out routine performance tests and adjustments on pipettes in the lab, it’s essential to maintain the integrity of the test while being cost and time-efficient. Get reliable results with the use of the OHAUS Explorer PLUS EXP semi-micro balances and the pipette adjustment kit.

Selecting the Correct Balance

When laboratory work and research requires accuracy to the hundred-thousandth, there is simply no room for error. The Explorer PLUS EXP series of semi-micro balances has been designed with the technology to ensure that your very specific weighing results are accurate. Sophisticated laboratories requiring accuracy and looking for innovative technology to obtain measurement results can find both in Explorer semi-micro balances.

The Explorer EXP balances come with the pipetting application in-built as standard, just simply add you pipette information to the balances and dispense upto 30 samples for an instant result.

Selecting the Correct Balance

Making Sure Your Pipetting is Accurate

When pipetting small volumes the effect of evopration becomes greater, to the point where it can invalidate your results. Get reliable results with the use of the OHAUS Pipette Adjustment Kit which significantly reduces the rate of evaporation in comparison to using an open beaker. To perform routine tests and adjustments, simply install the kit onto an Explorer EXP Semi-Micro balance—no tools needed.

A large capacity reservoir (120 ml) allows high volume pipettes to be measured, reducing the frequency at which it needs to be emptied. Pipettes as low as 100 μl volume can be checked precisely.

Capturing Your Data

When checking your pipettes it's important to ensure you keep a regular log of the results, this can be done via PC or by our SF40A printer.

The SF40A combines high performance and multiple functions to offer OHAUS quality and durability in a portable printer. The SF40A offers advanced functionality in an easy-to-use and set up printer at an exceptional value. This versatile printer is ideal for use in conjunction with OHAUS balances and scales in laboratory, industrial, and educational applications to ensure accurate documentation of weighing results.

Using the Right Pipette Tips

The precision and accuracy of even the best calibrated pipette can be wiped out if you choose the wrong kind of tips. Depending on the experiment you are doing, the wrong kind of tips can also make your pipette a source of contamination, lead to waste of precious samples or reagents—or even cause you physical harm in the form of repetitive stress injury (RSI).The OHAUS Biotix Ergonomix System uses positive stop technology to keep your ejection forces consistently low compared to other universal pipette tips.

Step Up Your Cosmetics Manufacturing with OHAUS

Honeywell LabReady™ Blends

The cosmetics industry is a billion-dollar industry, in continuous evolution. As manufacturers expand their range of products to respond to market needs, quality and regulatory requirements are also continuously evolving. The regulatory landscape in the cosmetics industry is complex, and there are several guidelines and regulations that manufacturers must follow. The regulatory approaches employed by different countries can differ significantly and are heavily reliant on the classification systems used to categorize cosmetic products as well as the ingredients utilized.

In recent decades, there has been a trend towards harmonizing regulations that govern cosmetic production and testing due to these diversities. The most important in this sector are: GMP Pharmacopoeia FDA Food Guidelines Local Regulations Good Manufacturing Practices (GMP) for cosmetic products. ISO 22716:2007 provides guidelines for GMP in cosmetic products, and this standard covers all aspects of the manufacturing process, including sourcing of raw materials, production, packaging, storage, and distribution.

Compliance with this regulation is essential for the cosmetics industry to maintain the safety and trust of consumers. Companies that fail to comply with these regulations risk legal action, damaged reputation, and loss of business.

The European Union has set out regulations under (EC) 1223/2009, which outlines the requirements for cosmetic products to be placed on the market within the EU. This regulation covers all aspects of the production process, including safety assessments, labeling, and packaging. To ensure the safety, quality, and effectiveness of their products, it is essential for Cosmetics manufacturers to invest in rigorous testing procedures.

Complying with the regulations and standards begins in R&D departments, throughout production, QC/QA laboratories including requirements for facilities, personnel, and the final products in order to comply with these standards and regulation.

Laboratories play a crucial role in ensuring the safety and quality of cosmetic products. The quality control/quality assurance labs in cosmetic companies are responsible for testing raw materials, formulations, and finished products, as well as monitoring production lines and personnel involved in the manufacturing process of the final products. To ensure accurate testing results, cosmetics labs are equipped with specialized instruments and equipment.

Lab Balances

Lab balances are used to measure precise amounts of raw materials and finished products. In the cosmetics industry, it is essential to measure small amounts of ingredients with great accuracy. Lab balances help to achieve this by providing precise measurements, ensuring consistency in the formulation of the product.

Centrifuges

Cosmetic products often contain a variety of ingredients, some of which may be in different phases or have different densities. Centrifuges can be used to separate these components based on their density and size. They are often used to determine the concentration of specific substances, such as preservatives and to control the proper homogenization of creams.

Overhead Stirrers

Overhead Stirrers perfectly meet such needs. They can be used to create emulsions or to ensure that the active ingredients of the cosmetic product are distributed evenly throughout the formulation. They can also be used to prepare pilot batches that are then transferred to production.

Moisture Analyzers

Moisture analyzers allow cosmetic manufacturers to determine the water content of their products. Water is a critical component of many cosmetic formulations, and accurate control of the water content is essential for ensuring the stability and safety of cosmetic products. Excessive moisture in cosmetic formulations can create an environment in which microorganisms can grow, leading to contamination and spoilage of the product. On the other hand, insufficient moisture can cause the product to dry out, affecting its texture, appearance, and performance.

Hotplates and Stirrers

Hot plates and stirrers are a useful piece of equipment in the R&D or QC laboratories where different procedures are being performed e.g. extraction, melting or mixing. Hot plates provide a controlled heat source for various applications in the cosmetic manufacturing process. They help heat, melt and mix solid ingredients, such as waxes and oils for the preparation of certain formulations. Precise temperature control assures the sample’s safety and refrains from overheating. Hotplate Stirrers  are used for the preparation of culture media for microbiological control. When the viscosity of the sample is too high for a hotplate stirrer, there is a need for a mixer with sufficient torque to agitate the viscous solution, cream or lotion.
