Exploring and grading coffee.

Use the PK100 to explore coffee. The extremely low retention design allows you to switch from coffee to coffee and easily change the grind size. The 98 mm burrs rotate at just 900 rpm to achieve filter grinds in ~5.5 seconds and the finer espresso doses in around 10 seconds.

The shop version comes with a 700 gram capacity hopper and bag clip so you can use it either for both cupping, brewing and retail. However, if you primarily want to grind coffee for customers check out the Compak retail grinders. Our favourite PK100 version is the Single Dose which is ideal for cupping, it has open collar and comes with a dosing cup.

Shipping & Installation


United Baristas Equipment Store ships to UK physical addresses. Free shipping is available on  products over £200, some exclusions apply and there are surcharges for some bulky and oversize products to remote regions. Any shipping costs are calculated at checkout.


Orders are dispatched as soon as practically possible after payment clearance. However, by arrangement, we can store purchased items in the UK warehouse until you’re ready to receive them. Tracking or delivery information is provided at the time of dispatch.


In stock products

In stock items are typically dispatched within two working days of payment clearance. We endeavour to keep the most popular products in stock.

Product options and customisation

Products that require bespoke assembly, customisation or manufacture have longer lead times. It’s best to order these items well in-advance as it is easier for us to store these items in the UK warehouse than it is to speed up customisation work or manufacturing.

Product options are typically completed within 5 working days. Comprehensive customisation work can take up to 50 working days depending on the complexity of the work and the availability of parts. If your item is being assembled or painted by the manufacturer, the factory lead-times apply.

Factory Orders

Orders that utilise production options, bespoke manufactured or not available from the UK warehouse are categorised as factory order items. These products are typically dispatched from the UK warehouse within 10 – 25 working days of payment clearance. Lead times vary by manufacturer, an overview is available. We will contact you with an expected dispatch date when you’re item is en route to the UK warehouse.

Bulky & Heavy Delivery

Bulky and heavy items are delivered palletised with a kerbside delivery service. Make sure you have the ability to move bulky and heavy items from the lorry into your premises.


United Baristas can install select items. Select the installation option at checkout to book this service.

Most products have installation requirements for electrical supply, water and waste. Installers are not able to perform plumbing or electrical work other than connecting the item. You can view the requirements on the product’s information page.

If you opt for installation, we will be in touch to arrange a pre-installation check. Assuming everything is ready, we will then be able to confirm an installation date. In many cases, the installer will bring the item with them to install.

Care & Maintenance


All grinders should be regularly cleaned to prevent build-up of grounds in the burrs and chamber. This is typically done in-house as part of the shutdown procedure. Cleaning your grinder both improves the quality of your coffee and helps prevent wear.

Product Information

Specific care and maintenance information is available for this product. To view videos and documentation, follow the product link on the Product Information section.

Maintenance & Service

With use, the burrs eventually lose their sharp edge becoming blunt. Replacement burrs are readily available and can be installed in-house by someone with moderate training or by an engineer as part of a service visit.

Carbon Footprint

Embodied carbon

United Baristas is establishing a programme to address the embodied carbon in the products we sell. We’ll update this section when the programme is launched. Your purchase of this product will be included in the programme and helps us to start this initiative. Thanks for your support.

Carbon emissions from use

Usage is the greatest cause of a product’s carbon footprint across all stages of its life from manufacture to disposal. There’s a tendency not to consider these emissions if the primary focus is on cutting waste. However, in 2022, approximately 182 grams of CO2e were emitted for every kWh generated in the United Kingdom. Shifts to renewable and nuclear generation, we well as the phasing out of coal and gas generation, will reduce the carbon intensity of electricity over time.

You can lower your electricity consumption and carbon emissions by both purchasing energy-efficient coffee equipment and using energy-efficient practices. More information is available on United Baristas.

Maintaining equipment

You can lower the carbon footprint of this product by keeping it in working condition and prolonging its working life. You can source parts and find engineering services on United Baristas Market. From a carbon reduction perspective, it makes sense to upgrade when a new product’s efficiency is great enough to outweigh the embodied carbon within several years.

End of life

As many components can be recycled and precious metal recovered, dispose of this product responsibly and do not discard in general waste. Further information is available in the product’s manual.

Repair, Reuse, Recycle

Repair & maintenance

Parts for this product are readily available and can be replaced. Minimise wear with regular care and maintain programme. Basic care and maintenance should be carried out in-house, as well as the replacement of some parts. Regular servicing and the replacement of electrical or boiler components can be performed by an engineer.


Aim to maximise the working life of all coffee-making equipment. If you should no longer have need for this item, sell it to another barista or coffee company on United Baristas Marketplace.


At end of life many of the components can be recycled. Dispose of this product responsibly and do not discard in general waste. Specific information is available in the product’s manual.
