Laboratory fabrication guide
A sink opening fixes more than the bowl. It fixes where an operator reaches, where water and waste travel, and how much dry work surface remains beside the wet work.
On Hup Hing's product page, the relationship is visible in one unit. It combines an integrated sink basin with a top-mounted hood or canopy and a lower cabinet. When a laboratory sink becomes part of a custom stainless steel station, those parts need to be planned together.[2]
Begin with the work at the sink
Write down what will be washed, rinsed or placed beside the basin. It may be small components, sample containers, tools or another item from the process. Note the largest item that must be handled, how it is held, where it goes after rinsing and whether it needs to dry on the same station.
The operator's approach matters as well. Mark the side from which the person normally arrives, the direction in which the hands move and the surface needed for a short pause after washing. Hup Hing's laboratory workbench guide recommends mapping the equipment, sink position, splash protection, service routes, storage and cleaning access before the stainless steel construction is finalised.[3]
This is where a catalogue photo stops being enough. A basin can look well placed and still leave the operator reaching across a dry instrument or turning a wet part into a wall.
Draw the wet zone before the cut-out
Put the basin outline on the room drawing before deciding the final worktop size. Add the tap clearance, the rear upstand or backsplash if the work calls for one, the splash direction and the usable surface beside the sink. Keep the dry instrument area visible on the same drawing.
Hup Hing's existing guide makes the same point in practical terms: sink position should follow the actual workflow rather than being placed at the end by habit. It also calls out tap clearance, splash protection, waste routing and the relationship between wet work and dry instruments.[3]
Equipment footprints belong on the drawing too. The company's laboratory work-table guide starts with the equipment footprint and user workflow, then moves to dimensions, surface details, under-bench needs and site constraints.[4] That order helps the fabricator see why the sink is in a particular position instead of treating it as a late cut-out.
Leave water, waste and service routes in the drawing
A sink is connected equipment. Show the incoming water point, drain location, pipe route, access to valves and any wall or floor obstruction that could affect installation. If the station includes a hood or canopy, show the intended exhaust direction and the space around the connection. Do not fill in a pipe size, chemical-compatibility statement or ventilation result from a photograph.
Access below the worktop deserves a line on the drawing. Someone may need to inspect a connection, clean beneath the basin or reach a service point without dismantling the whole station. A lower cabinet can be useful, but its doors and internal storage must not block the work needed around the sink.
Choose what sits below the work bay
The lower part of the station affects daily access. Hup Hing's product page describes a lower cabinet for cleaning tools, chemicals or accessories, alongside the sink and hood arrangement.[2] That is a product-specific layout, not a rule that every laboratory sink needs an enclosed cabinet.
Decide whether the area below should stay open, hold a shelf, or use doors. Check the door swing against the operator's standing position. Leave room for cleaning around the base and keep any service panel reachable. If bottles or tools are stored below, state their approximate size and how often they are taken out. These small details change the usable work area more than a polished product photograph suggests.
Make the quotation brief easy to draw
A first enquiry does not need to be a finished engineering specification. It does need enough information for the fabricator to draw the right problem. Send:
- a room plan or marked-up photo showing walls, doors, floor level and nearby equipment;
- the outside dimensions available for the station, plus the operator side;
- the sink or basin size you are considering and the largest item that will be washed;
- water, waste, power and exhaust points already available at the site;
- the storage arrangement, access panels and cleaning access you expect below the work bay;
- the process, liquids and cleaning routine that the buyer's technical team will review.
Photographs from two angles are often more useful than one carefully cropped image. Include the route used to bring the station into the room as well. A unit that fits the wall can still be difficult to move through a doorway or around an existing machine.
Two points to settle before fabrication
Should the basin sit on the left or the right?
There is no universal side. Choose it from the operator's approach, the drain point, the adjacent equipment and the place where washed items are transferred. Hup Hing's published rinse-station article describes basin side and faucet position as details that can be adjusted when the operator direction, drain point and surrounding equipment are known.[5]
Does adding a sink make a workbench suitable for every laboratory?
No. The sink is one part of the station. Material selection, fabrication details, drainage, exhaust, cleaning method, access and the room's own requirements still need a project review. The product page shows one integrated Hup Hing arrangement; it does not replace the buyer's approval of the final design.[2]
Start with the actual room
Kilang Kejenteraan Hup Hing Sdn Bhd provides custom stainless steel fabrication for laboratory and industrial applications from Negeri Sembilan, Malaysia, and its official site states that the business has provided fabrication services since 1980.[1] The relevant Hup Hing pages are the Cleaning Station & Fume Hood product page, the laboratory workbench guide and the Medical & Lab Industries range. Send the room drawing, process notes and preferred arrangement through the Hup Hing enquiry page or WhatsApp +6016-330 2905.
Discuss a laboratory sink station
Share the work process, room constraints, basin position and service points. Hup Hing can review the fabrication brief before the drawing is released.
