Accurate, safe and efficient powder and liquid dispensing is now possible! Watch this video and see how easy it is with the XPR Automatic Balance. 

Accuracy and Ease of Handling

Manually weighing out powders with a spatula can be a difficult, slow and repetitive task, particularly when many samples have to be weighed. It also takes a lot of skill and experience to weigh accurately in the low milligram range as the physical properties of different powders vary considerably; statically charged or hygroscopic samples can make that task even more difficult.

Safety

Hazardous and toxic substances, including active pharmaceutical ingredients, can pose a risk to health, even at the nanogram level. It is very easy for particles to become airborne, especially when dealing with light, low density and fluffy compounds, which need to be handled with extreme care.

Data Management and Traceability

All measurement and process data must be fully traceable and securely stored, and readily accessible for audit purposes.

Would you like to weigh solid substances faster and avoid repetitive, time-consuming manual steps? Or perhaps you want to take advantage of the lower minimum weights offered by automated solutions and use much less of precious substances? Do you want to improve user safety due to reduced exposure risk?

Safety Benefits

Safety is a key advantage of the XPR Automatic Balance. Potentially harmful or unknown powders are stored in sealed dosing heads and simply clipped onto the balance when required, significantly reducing the exposure risk for the operator. Automated powder dispensing has a low risk of spillage and is carried out inside a closed system (draft shields). If necessary, the whole system can easily be placed inside a safety cabinet or glove box for a higher level of protection.

Increased Productivity

Precise and accurate dispensing of powders manually requires great concentration from the technician and has a high risk of human error, which can lead to out-of-specification (OOS) and out-of-tolerance (OOT) measurements. With automated weighing this error-risk is minimized and the operation is significantly faster.

Economical Substance Usage

Automated dispensing with the XPR Automatic Balance reduces the minimum net sample weight by up to 30%. This means possible saving of up to 75% of your valuable substance or rare samples, and consequently contributes to a fast return on investment.

Operation of the XPR Automatic Balance

1. Attach the dosing head to the system. An RFID chip in the dosing head can store all the necessary information about the substance.
2. Define the amount you wish to dispense and the acceptable tolerance.
3. The system will dispense the requested amount, automatically record the measurement data and print it out, if required.

Automatic Documentation

The XPR Automatic Balance can be combined with LabX™ laboratory software for a full workflow solution offering the benefits of comprehensive data handling and sample tracking functionalities. All measurement and process data, including metadata, is stored in a secure centralized database and can be accessed instantly, so you can ensure that you are audit ready.

• Preparation of samples for analysis in pharmaceutical quality assurance or quality control (QA/QC), where active pharmaceutical ingredients (APIs) are usually classed as unknown potency and must be considered as high risk.

• Weighing of powders for high-throughput experimentation (HTE) in pharmaceutical drug development. Powder weighing becomes a bottleneck when multiple powders need to be weighed in varying amounts to set up parallel experiments, such as salt screening or solubility screening applications. Faster results mean faster time to market and greater profitability.

• Bottling or filling applications, where there is a continuous requirement to weigh out precise amounts of powders into specific container formats. This may be a commercial supplier of chemicals and reagents, or an internal company department that provides a central service supplying substances to other parts of the organization, such as a central compound management facility.

• Laboratory safety, especially when handling toxic or hazardous substances, is of increasing importance to health and safety departments in many industries. This application note explains how using an XPR Automatic Balance for automated powder and liquid dispensing can significantly reduce exposure risk, and provide safety benefits to the researcher when handling toxic or hazardous compounds in the laboratory.

Simply add a sample changer to your XPR Automatic Balance and dispense solids and liquids into up to 30 containers in one fully automated run! Our large portfolio of adapters supports many of the standard vials and containers used in a modern laboratory. In addition, we offer specific adapters for capsule filling applications.

A fully automated system with high throughput may be appropriate for situations where many powders need to be weighed in small quantities, for example, for catalyst screening, formulation experiments or solubility screening. The CHRONECT XPR Robotic Powder Dispensing platform can accurately weigh up to 32 different powders into as many as 288 vials in a single batch. The system can simultaneously house up to three different plates accommodating between 36 (3 x 12) and 288 (3 x 96) vials or containers from 1 to 8 mL in volume.
